0:00:02 > 0:00:04Sports people must be fast,
0:00:04 > 0:00:05strong...
0:00:08 > 0:00:09..and deadly accurate.
0:00:11 > 0:00:16But did you know they wouldn't be able to compete without maths?
0:00:16 > 0:00:17Time-keeping...
0:00:19 > 0:00:23..scoring, speed...
0:00:23 > 0:00:25shape, distance.
0:00:25 > 0:00:27It's all mathematics.
0:00:27 > 0:00:31A tenth of a second or just a few millimetres
0:00:31 > 0:00:35can transform an ordinary person into a world champion.
0:00:35 > 0:00:38Great Britain get the gold!
0:00:38 > 0:00:41- This is...- 3, 2, 1...- Go!
0:00:41 > 0:00:44We take teams to a secret location...
0:00:44 > 0:00:46This really IS a special place.
0:00:49 > 0:00:50This is fabulous!
0:00:50 > 0:00:53..to be given a behind-the-scenes tour...
0:00:53 > 0:00:56HE SCREAMS
0:00:56 > 0:00:59..and meet their sporting heroes...
0:00:59 > 0:01:00Hi, nice to meet you.
0:01:01 > 0:01:03..who'll give them a maths challenge.
0:01:03 > 0:01:083, 2, 1, go!
0:01:08 > 0:01:09- Go!- Go!
0:01:09 > 0:01:12And if they get it right...
0:01:12 > 0:01:1317!
0:01:14 > 0:01:18One, two, three, four...
0:01:18 > 0:01:22Probability suggests we should dive to the bottom right hand corner.
0:01:22 > 0:01:25..they win a gold medal.
0:01:27 > 0:01:30This challenge is all about football.
0:01:31 > 0:01:36Football is played on a rectangular grass pitch up to 120 metres long
0:01:36 > 0:01:40and 90 metres wide. Two teams of 11-a-side kick a round ball
0:01:40 > 0:01:44into a goal on the opposite team's half.
0:01:44 > 0:01:48On the pitch, only the goalkeeper can handle the ball,
0:01:48 > 0:01:49and only in the penalty area.
0:01:49 > 0:01:54The games last for 90 minutes and the team with the most goals wins.
0:01:54 > 0:01:58So, are you ready? 3, 2, 1, Go!
0:02:00 > 0:02:04Today, football fans Hayden and Romario are being taken
0:02:04 > 0:02:09to a secret location to complete their 3, 2, 1, Go! challenge.
0:02:11 > 0:02:14They have no idea where they're going.
0:02:16 > 0:02:19They've both been playing football since they could walk.
0:02:20 > 0:02:22I get so much enjoyment out of it.
0:02:22 > 0:02:25Yeah, and you can get away from all homework and stuff
0:02:25 > 0:02:28- and it's just a way of freedom, really.- Yeah.
0:02:28 > 0:02:32Hayden gets to enjoy a lot of that freedom
0:02:32 > 0:02:35because he plays for the Potters Bar Crusaders.
0:02:35 > 0:02:38And with them, he has won the league.
0:02:38 > 0:02:42He's also played in the Arsenal soccer schools, which is good,
0:02:42 > 0:02:45because they're both die-hard supporters of one club.
0:02:45 > 0:02:47BOTH: Arsenal.
0:02:47 > 0:02:51I used to live sort of around that area, so it's sort of my home team.
0:02:51 > 0:02:55Romario plays for his local club, Barnet Azzurri,
0:02:55 > 0:02:58and has been on two successful tours with the team.
0:02:58 > 0:03:01He's also played AGAINST the Arsenal Academy,
0:03:01 > 0:03:05but they both hope to play FOR Arsenal one day.
0:03:05 > 0:03:10I like the way they play, really. The players are very skilful.
0:03:11 > 0:03:14They ARE extremely skilful.
0:03:14 > 0:03:18In fact, they're one of the most successful British clubs,
0:03:18 > 0:03:21winning 13 First Division and Premier League titles,
0:03:21 > 0:03:25two League Cups and no less than ten FA Cups.
0:03:27 > 0:03:30And it looks like the lads have just spotted where they're going.
0:03:32 > 0:03:35- Arsenal Training Centre. - Arsenal Training Centre.
0:03:35 > 0:03:37Yes, that's right.
0:03:37 > 0:03:41- Amazing.- Amazing. Absolutely great.
0:03:42 > 0:03:46This is where their favourite team Arsenal train.
0:03:46 > 0:03:51With ten full-size pitches, each to the exact specification of their home stadium,
0:03:51 > 0:03:55they come here to prepare for all their matches.
0:03:55 > 0:03:59Today the pitches are covered in snow, so they're training indoors.
0:04:03 > 0:04:06It's a top-secret location,
0:04:06 > 0:04:10and usually only the players are allowed in.
0:04:10 > 0:04:14Hi, guys, welcome to Arsenal Football Club. These are for you.
0:04:14 > 0:04:16If you'd like to follow me.
0:04:16 > 0:04:20But today, Romario and Hayden are going to be given special access.
0:04:22 > 0:04:23BOTH: Amazing.
0:04:23 > 0:04:25So who've you spotted, lads?
0:04:25 > 0:04:26Thierry Henry.
0:04:26 > 0:04:29Yep, there he is, playing keepy-uppy with Johan Djourou.
0:04:29 > 0:04:33- Sagna.- Pires, Sagna.
0:04:37 > 0:04:41And there's Alex Oxlade-Chamberlain playing table tennis...?
0:04:43 > 0:04:47And one of the top players, Per Mertesacker, has taken a break
0:04:47 > 0:04:50to give them their 3, 2, 1, Go! maths challenge.
0:04:50 > 0:04:51- Hello.- Hello, nice to meet you.
0:04:51 > 0:04:53And there's someone else with him, too.
0:04:53 > 0:04:56- And you?- Romario. - Do you play football?
0:04:56 > 0:04:58Yeah. Hello, Wenger!
0:04:58 > 0:05:01Um, that's Monsieur Wenger to you!
0:05:01 > 0:05:06After all, it is Arsene Wenger, the Arsenal manager. Best behaviour, boys.
0:05:06 > 0:05:09- Do you play football?- Yeah. - What position?- Centre mid, up front.
0:05:09 > 0:05:13I play right back.
0:05:13 > 0:05:15I'm impressed.
0:05:15 > 0:05:19New talents...for our club, maybe?
0:05:19 > 0:05:25Per Mertesacker is a defender and, as well as playing for Arsenal,
0:05:25 > 0:05:28he's also played for his national team, Germany,
0:05:28 > 0:05:31where he's won 78 international caps.
0:05:31 > 0:05:36And it's rumoured that he was bought by Arsenal for £10 million.
0:05:36 > 0:05:39What's the best game you've played in?
0:05:39 > 0:05:43Oooh, I've played many games for the national team of Germany,
0:05:43 > 0:05:47and...we have some good games,
0:05:47 > 0:05:49but with Arsenal, every game is very massive.
0:05:49 > 0:05:54What's more fun and exciting - playing for Arsenal or Germany?
0:05:54 > 0:05:58The German league is good, obviously is very good,
0:05:58 > 0:06:01and I like to play there for a long, long time,
0:06:01 > 0:06:06but now I change my mind and England is much, much better.
0:06:06 > 0:06:11OK, enough idle banter, then. Time for their 3, 2, 1, Go! Challenge.
0:06:11 > 0:06:13OK, listen, here's your challenge.
0:06:13 > 0:06:16Our goalie Wojciech Szczesny always studies
0:06:16 > 0:06:18where strikers place the ball.
0:06:18 > 0:06:22Speak of the devil, there's Wojciech Szczesny himself!
0:06:24 > 0:06:28Anticipating where penalty might go is key to saving it.
0:06:28 > 0:06:31Watch where the strikers aims the penalties
0:06:31 > 0:06:34and predict where his next one will be.
0:06:34 > 0:06:363, 2, 1, Go!
0:06:38 > 0:06:42So the boys have been given their prediction challenge.
0:06:42 > 0:06:45But first, an outside pitch has to be cleared of snow.
0:06:46 > 0:06:47Wow.
0:06:49 > 0:06:52I wish I could just jump in and play!
0:06:52 > 0:06:54Yeah. In an Arsenal shirt.
0:06:58 > 0:07:03Now, the boys are up against the 3, 2, 1, Go! striker,
0:07:03 > 0:07:08nicknamed White Boots because he, um, has...white boots.
0:07:08 > 0:07:12Some say he never misses the goal.
0:07:12 > 0:07:15Now, the boys have to watch White Boots take penalties,
0:07:15 > 0:07:19then predict which direction he will go when they face him
0:07:19 > 0:07:22for the final shot. You feeling lucky, boys?
0:07:26 > 0:07:28Right, we've got to work out what side he favours
0:07:28 > 0:07:31and plot them on the board. Let's get our pen. OK.
0:07:31 > 0:07:36Right, on the board is a diagram that represents the goal.
0:07:36 > 0:07:39It's divided into four quarters. The boys have to mark on the table
0:07:39 > 0:07:44which quarter White Boots aims each penalty,
0:07:44 > 0:07:47so they can work out his statistics afterwards.
0:07:49 > 0:07:52And there he goes with the first shot.
0:07:52 > 0:07:54And White Boots puts it straight in!
0:07:54 > 0:07:57- First one right. - Yeah, right in the corner.
0:07:57 > 0:07:59So, they've marked it on the board.
0:07:59 > 0:08:01- Let's see where the next one goes. - Yep.
0:08:03 > 0:08:05- Bottom left, yeah?- Yeah.
0:08:05 > 0:08:07Now, I know White Boots is a deadly shot,
0:08:07 > 0:08:11but this keeper doesn't seem to be trying very hard.
0:08:11 > 0:08:12- Bottom right.- Yeah.
0:08:12 > 0:08:15Predicting where a striker is likely to place a ball
0:08:15 > 0:08:19will give an added advantage to any keeper.
0:08:19 > 0:08:21- Bottom right again. - About there?- Yeah.
0:08:21 > 0:08:25And to know that, they must study a striker's form.
0:08:25 > 0:08:28That's bottom left that time.
0:08:28 > 0:08:32Oh, White Boots, off the bar but behind the line.
0:08:32 > 0:08:34- That one had a bit of a bounce there.- Yeah.
0:08:36 > 0:08:42Like a penalty. Top left, little bit more middle. Yeah, about there.
0:08:42 > 0:08:44About there, yeah.
0:08:44 > 0:08:47And deadly White Boots is racking up the goals,
0:08:47 > 0:08:49he's giving the boys plenty to think about.
0:08:49 > 0:08:54- Bottom right again.- Up there. - Yeah. He favours bottom right.
0:08:54 > 0:08:56Bottom right-hand corner, yeah.
0:08:56 > 0:08:59Statistics are incredibly important to sport teams.
0:08:59 > 0:09:01It helps them to know how good their players are
0:09:01 > 0:09:03and also to size up their competitors.
0:09:05 > 0:09:10- Bottom right again. About there, maybe?- Yeah, yeah.
0:09:10 > 0:09:16Right, White Boots has finished his run of penalties. What's next, lads?
0:09:16 > 0:09:20Now we need to add up each quarter and see how many there is.
0:09:20 > 0:09:22One, two, three, four, five, six, seven, eight, nine.
0:09:22 > 0:09:24Nine for this one.
0:09:24 > 0:09:27There's just one in this one.
0:09:27 > 0:09:29This one's got four. One, two, three, four.
0:09:29 > 0:09:34And the last one's got one, two, three, four, five, six.
0:09:34 > 0:09:39- So add them all up. - That's 10... 14 plus 6 is 20.
0:09:39 > 0:09:44They've got the number of shots aimed at each quarter of the goal.
0:09:44 > 0:09:50So we've got 20 shots, so we need to work out the percentage out of 100.
0:09:50 > 0:09:53Exactly. To work out what percentage of the total goals
0:09:53 > 0:09:57went into each quarter of the goal, they need to work out
0:09:57 > 0:10:00what percentage of the total each individual goal is worth.
0:10:00 > 0:10:03So that would be 100 divided by 20.
0:10:04 > 0:10:07- Which equals...- Five.- Five.
0:10:07 > 0:10:10So that equals one single shot.
0:10:12 > 0:10:16That's right. For 20 shots, each one is 5% of the total.
0:10:16 > 0:10:20So what percentage of the total went into each quarter?
0:10:20 > 0:10:23So that means each one equals 5. So 9 x 5...
0:10:23 > 0:10:28That equals 45% for this quadrant.
0:10:28 > 0:10:31This one's just got 1, so that will be 1 x 5, which is 5%.
0:10:34 > 0:10:40This one down here has 4, which will be 5 x 4, which is 20. 20%.
0:10:41 > 0:10:43And the last one up here's got 6. 6 x 5 equals 30,
0:10:43 > 0:10:46so that means 30%.
0:10:46 > 0:10:51So the right-hand corner was the one with the most percentage of him shooting.
0:10:51 > 0:10:53That's right.
0:10:53 > 0:10:5745% of White Boots' shots went to the bottom right-hand corner.
0:10:57 > 0:11:01So now it's time to face him yourselves. What's your plan?
0:11:01 > 0:11:05- It's most likely...- Most likely to be the bottom right-hand corner,
0:11:05 > 0:11:06as the probability is 45%.
0:11:06 > 0:11:11- He could go here, as that's second highest.- Yeah, second highest.
0:11:12 > 0:11:14All the others are less.
0:11:14 > 0:11:17So probability suggests that if we were to save this next shot,
0:11:17 > 0:11:22we should dive to the bottom right corner. So who's going to do this?
0:11:22 > 0:11:23I'll go and try and save it.
0:11:24 > 0:11:26So, crunch time.
0:11:26 > 0:11:29Did the boys study the striker's previous form well enough?
0:11:29 > 0:11:34They nearly went for the top left, because it had a pretty high percentage of goals,
0:11:34 > 0:11:37but they decided to go with bottom right.
0:11:37 > 0:11:42Can this prediction mean Romario can get behind the ball by diving to his left?
0:11:42 > 0:11:46White Boots looks determined to remain unbeaten.
0:11:46 > 0:11:50Here he comes. It's got power.
0:11:50 > 0:11:52Romario commits to the dive...
0:11:52 > 0:11:55White Boots goes bottom right...
0:11:55 > 0:11:58- and Romario's got it! - Yes, he saved it!
0:11:58 > 0:12:01White Boots, you are SO predictable!
0:12:03 > 0:12:04Bottom right looks favoured.
0:12:04 > 0:12:08Romario and Hayden stepped up to the challenge.
0:12:08 > 0:12:11They recorded the direction of White Boots' penalties
0:12:11 > 0:12:13and worked out his shooting statistics.
0:12:13 > 0:12:16They made their prediction based on the facts,
0:12:16 > 0:12:19before facing White Boots' final shot.
0:12:19 > 0:12:23And they came home heroes. What was your prediction again, boys?
0:12:23 > 0:12:25BOTH: Bottom right.
0:12:27 > 0:12:30They have completed their 3, 2, 1, Go! challenge,
0:12:30 > 0:12:33and Arsenal player Per Mertesacker has got their prizes.
0:12:33 > 0:12:35- First.- Thank you.
0:12:38 > 0:12:40Thank you.
0:12:40 > 0:12:42- Hayden...- Thank you.
0:12:44 > 0:12:45- Well done.- Thank you.
0:12:45 > 0:12:48- How was that, boys? - That was brilliant!
0:12:48 > 0:12:51Meeting Per, that's amazing, and seeing all the Arsenal players.
0:12:51 > 0:12:53Yeah, speaking to them in person, as well.
0:12:53 > 0:12:57Brilliant, once-in-a-lifetime opportunity.
0:12:57 > 0:13:00And what about the big boss, Arsene Wenger?
0:13:01 > 0:13:03Should have asked him for a trial!
0:13:03 > 0:13:07Now your teacher has a challenge for you.
0:13:07 > 0:13:103, 2, 1, Go!
0:13:14 > 0:13:17Sports people must be fast,
0:13:17 > 0:13:19strong...
0:13:20 > 0:13:22..and deadly accurate.
0:13:24 > 0:13:28But did you know they wouldn't be able to compete without maths?
0:13:29 > 0:13:30Time-keeping...
0:13:32 > 0:13:34..scoring,
0:13:34 > 0:13:36speed...
0:13:36 > 0:13:38shape, distance.
0:13:38 > 0:13:41It's all mathematics.
0:13:41 > 0:13:45A tenth of a second or just a few millimetres
0:13:45 > 0:13:49can transform an ordinary person into a world champion.
0:13:50 > 0:13:51Great Britain get the gold!
0:13:51 > 0:13:55- This is...- 3, 2, 1...- Go!
0:13:55 > 0:13:57We take teams to a secret location...
0:13:57 > 0:14:00This really is a special place.
0:14:02 > 0:14:04This is fabulous.
0:14:04 > 0:14:06..to be given a behind-the-scenes tour...
0:14:09 > 0:14:12..and meet their sporting heroes..
0:14:12 > 0:14:13Hi, nice to meet you.
0:14:14 > 0:14:16..who'll give them a maths challenge.
0:14:16 > 0:14:213, 2, 1, Go!
0:14:21 > 0:14:23- Go!- Go!
0:14:23 > 0:14:25And if they get it right...
0:14:25 > 0:14:2717!
0:14:28 > 0:14:31One, two, three, four...
0:14:31 > 0:14:35Probability suggests we should dive to the bottom-right corner.
0:14:35 > 0:14:38..they win a gold medal.
0:14:38 > 0:14:42This challenge is all about cycling.
0:14:46 > 0:14:50Track cycling takes place in specially-built velodromes,
0:14:50 > 0:14:55made up of two 180-degree circular bends connected by two straights.
0:14:55 > 0:14:59Cyclists race at speeds of up to 80 kilometres per hour
0:14:59 > 0:15:03on specially designed bikes with no brakes. So are you ready?
0:15:04 > 0:15:053, 2, 1, go!
0:15:09 > 0:15:13Today's cycling fans, Dale and Jermaine, are being taken to a secret location
0:15:13 > 0:15:17in Manchester to complete their 3, 2, 1, Go! challenge.
0:15:17 > 0:15:22Dale likes nothing more than going out into the countryside on his BMX.
0:15:22 > 0:15:28I do jumps with my mates, go across the mud parts and get wet. Muddy.
0:15:30 > 0:15:32Dale is mad about cycling.
0:15:32 > 0:15:36He's been riding a bike for over ten years,
0:15:36 > 0:15:39and hasn't looked back since discovering BMXing,
0:15:39 > 0:15:43but loves watching the track cycling on TV.
0:15:43 > 0:15:48Although the lads don't know where they're going yet, they're already having a laugh.
0:15:48 > 0:15:52Jermaine is a sports star in the making.
0:15:52 > 0:15:54As a competitive swimmer and cyclist,
0:15:54 > 0:15:56he's training for a triathlon.
0:15:56 > 0:15:59He's also been cycling for ten years
0:15:59 > 0:16:02and likes watching the swimming and cycling on TV.
0:16:02 > 0:16:07So, as budding sportsmen, is there anywhere you've ever dreamt of going?
0:16:07 > 0:16:12The one place I would like to go in Manchester cycling is a velodrome, because I've never been before.
0:16:12 > 0:16:14Well, lads, this is your lucky day.
0:16:14 > 0:16:16You've seen where we're headed?
0:16:16 > 0:16:19- Professional cycling. - Yep, you've got it.
0:16:22 > 0:16:28This is the National Cycling Centre in Manchester and it was Britain's first indoor Olympic cycling track.
0:16:28 > 0:16:32A cycle arena is called a velodrome.
0:16:32 > 0:16:37And this one is where members of the Great Britain Olympic team are training.
0:16:40 > 0:16:44This is where the boys will be given their 3, 2, 1, Go! challenge.
0:16:47 > 0:16:50Hi Jermaine, Dale, welcome to the National Cycling Centre.
0:16:50 > 0:16:52Do you want to come this way?
0:16:52 > 0:16:56The boys are going to be given a special tour of the velodrome.
0:16:58 > 0:17:03You've seen some of the bikes we've got here. These are the bikes that we use on the velodrome now.
0:17:03 > 0:17:06And they're just about to see the track for the first time.
0:17:06 > 0:17:10- OK, guys, this is the track.- Wow! - Pretty impressive, yeah?- Yeah.
0:17:12 > 0:17:17And today Team GB are training with their coach...on a motorbike.
0:17:20 > 0:17:21Have a closer look.
0:17:27 > 0:17:30- It's a big place though, innit? - It's really big, yeah.
0:17:30 > 0:17:32And you're about to get the track all to yourselves.
0:17:32 > 0:17:37It's your chance to take a spin while Team GB take a break in their training.
0:17:37 > 0:17:40Do you think you'd be able to get round the banking here?
0:17:40 > 0:17:44- No, I reckon I'll slip.- I don't blame you for being a bit worried, Dale!
0:17:44 > 0:17:47You see the way the track is? As you come into the banking here,
0:17:47 > 0:17:50the steepest part goes to 42 and a half degrees.
0:17:50 > 0:17:53What you need to do when you're starting out is just pedal faster.
0:17:53 > 0:17:57- Yeah, yeah.- Yeah? So I reckon you would be able to ride on here.
0:17:57 > 0:18:00It'd be hard, but I'll have a go, yeah.
0:18:02 > 0:18:05Right then, better get to the bike store to get fitted up.
0:18:05 > 0:18:06Come and have a look.
0:18:06 > 0:18:10This is the biggest fleet of track bikes in the UK,
0:18:10 > 0:18:13and each bike is designed just for track cycling.
0:18:13 > 0:18:18With just one gear and an aerodynamic frame,
0:18:18 > 0:18:20these bikes are built for speed.
0:18:20 > 0:18:23- How fast will they go? - How fast will they go?
0:18:23 > 0:18:26They actually go as fast as the person who's pedalling them.
0:18:26 > 0:18:29OK, and they can get them up to around 62k.
0:18:29 > 0:18:32Our squad riders can go a lot faster.
0:18:32 > 0:18:36Yep, I think that's fired the boys up. Let's get you on the track.
0:18:36 > 0:18:42First thing you need to both know is you have no brakes on your bikes.
0:18:42 > 0:18:49OK, no brakes! Well it's too late to chicken out. You're on your own and it's time for the warm up.
0:18:49 > 0:18:53Go on, Jermaine. Go fast. Don't be scared.
0:18:53 > 0:18:54If you fall off, you fall off!
0:18:54 > 0:18:56HE LAUGHS
0:18:56 > 0:18:58If you die, you die!
0:18:59 > 0:19:02Those are, erm, interesting words of encouragement from Dale,
0:19:02 > 0:19:05but it doesn't seem to have put Jermaine off.
0:19:05 > 0:19:07Just get a feel of the bike.
0:19:11 > 0:19:13- Dale, are you ready?- Yeah.
0:19:13 > 0:19:15Off you go, Dale.
0:19:17 > 0:19:19They're both picking up speed - total naturals.
0:19:19 > 0:19:23I think they're ready for a time trial. Jermaine is off first.
0:19:23 > 0:19:263, 2, 1, go!
0:19:26 > 0:19:28Fast as you can!
0:19:29 > 0:19:32And he's looking fast!
0:19:32 > 0:19:35Next up, the clock starts for Dale.
0:19:35 > 0:19:383, 2, 1, go!
0:19:41 > 0:19:43The boys are whizzing round.
0:19:43 > 0:19:46Jermaine has hit his home straight and is about to cross the line.
0:19:46 > 0:19:50Fast as you can. All the way to the line, keep going.
0:19:50 > 0:19:54Don't forget to keep pedalling! Keep pedalling.
0:19:54 > 0:19:5730.06.
0:19:57 > 0:20:02That's a good time for Jermaine, but Dale is flying round the track.
0:20:02 > 0:20:05It doesn't look like he's having any problems with the banking.
0:20:05 > 0:20:07All the way, Dale, all the way.
0:20:08 > 0:20:1026.22.
0:20:10 > 0:20:12Amazing times.
0:20:13 > 0:20:16- Well done, Dale. How did you find that?- Easy.
0:20:16 > 0:20:20Easy? You did it in 26.22 seconds. Well done.
0:20:20 > 0:20:22DALE BREATHES HEAVILY
0:20:22 > 0:20:23- You out of breath?- Yeah.
0:20:26 > 0:20:27That's a great job, lads.
0:20:27 > 0:20:32You've managed some super-fast times on the very track our elite cyclists train and race on,
0:20:32 > 0:20:36and today a world champion has taken a break in her training
0:20:36 > 0:20:40to give the guys their 3, 2, 1, Go! challenge.
0:20:40 > 0:20:42- Hi guys, my name's Sarah. What's your name?- Dale.
0:20:42 > 0:20:45- Hi, Dale.- I'm Jermaine. - Hi, Jermaine, how are you?- Fine.
0:20:45 > 0:20:48- Have you had a good day at the velodrome?- Yeah.
0:20:48 > 0:20:52Sarah Storey is world champion in paracycling.
0:20:52 > 0:20:55She has competed at no less than five Paralympic Games,
0:20:55 > 0:20:58where she's won 18 medals
0:20:58 > 0:21:01and she has an incredible 71 world records!
0:21:03 > 0:21:08And it was at the Manchester velodrome where Sarah learned to ride a track bike.
0:21:09 > 0:21:13- How did you find it on the velodrome?- We did a time trial.
0:21:13 > 0:21:17- You did?- Yeah.- Over one lap?- Yeah. - 250 metres. Do you know what time you did?
0:21:17 > 0:21:20- 26 point-something seconds.- Pretty quick.- 30.6.- That's all right.
0:21:20 > 0:21:21How did you find it?
0:21:21 > 0:21:24- Was it quite hard getting the gear going from standing?- Yeah.- Yeah...
0:21:24 > 0:21:26I found it harder from there.
0:21:26 > 0:21:29Yeah, getting onto the track and staying on the track and the bank,
0:21:29 > 0:21:31- it's not as easy as it looks, is it?- No.
0:21:31 > 0:21:35What was the year that you won your first gold medal?
0:21:35 > 0:21:37I won my first gold medal in 1992 when I was 14,
0:21:37 > 0:21:43and that was in Barcelona at the 1992 Paralympic Games.
0:21:43 > 0:21:47Amazing! 14 years old! That's just one year older than the boys.
0:21:47 > 0:21:50But now they have a chance to win their very own medals.
0:21:50 > 0:21:54Sarah has got Dale and Jermaine's 3, 2, 1, Go! challenge.
0:21:54 > 0:21:55Listen up, boys.
0:21:56 > 0:22:00I race 12 laps of the velodrome, that's in the individual pursuit,
0:22:00 > 0:22:02but I can pick my position on the track.
0:22:02 > 0:22:07Calculate how much further I would travel if I rode it on the red line
0:22:07 > 0:22:09rather than on the black line during my race.
0:22:09 > 0:22:12OK? 3, 2, 1, go!
0:22:12 > 0:22:17So Dale and Jermaine have been given a measuring and arithmetic challenge.
0:22:17 > 0:22:21Right, so we've got to measure the black and red line down there, let's go.
0:22:24 > 0:22:30The track is oval-shaped, which means the inside edge is shorter than the outside one.
0:22:30 > 0:22:34So it makes sense for the riders to stick to the inside edge on the track.
0:22:34 > 0:22:37That's the black line.
0:22:37 > 0:22:39But there are times when they might need to move up the track
0:22:39 > 0:22:42like if they need to overtake someone in front of them.
0:22:42 > 0:22:46This would take them to the next line up the bank, the red line.
0:22:46 > 0:22:50Although this allows the rider to get a better position in the race,
0:22:50 > 0:22:53it means that they will have to cycle a longer distance.
0:22:53 > 0:22:55But how much further would the cyclist travel
0:22:55 > 0:22:59if they spent the whole race on the red line rather than the black?
0:22:59 > 0:23:05So, first up to work this out they need to measure both the black and red lines
0:23:05 > 0:23:08that are marked out on the track, then do the sums.
0:23:08 > 0:23:15Before they start, we thought it might be a good idea to clear the track of riders!
0:23:15 > 0:23:17One, two, three...
0:23:17 > 0:23:21Being able to understand distance is really important in cycling,
0:23:21 > 0:23:25as every race is defined by the maximum distance the cyclist will travel.
0:23:31 > 0:23:33Keep going, all the way round!
0:23:33 > 0:23:36..248, 249, 250.
0:23:36 > 0:23:42- Let's swap.- Anyone else apart from me spotted a clue on the track?
0:23:42 > 0:23:46Right that's the black line done, next it's the red.
0:23:46 > 0:23:48Three, four...
0:23:53 > 0:23:57253, 254, 255.
0:23:57 > 0:24:00255. I'll go and write it down.
0:24:00 > 0:24:02Good work, lads.
0:24:02 > 0:24:04Hurry up!
0:24:04 > 0:24:06Time for the sums.
0:24:06 > 0:24:10- So what was the...- Black line distance, that's 250 metres.
0:24:12 > 0:24:15And the red line was 255.
0:24:19 > 0:24:21The difference must be five metres.
0:24:21 > 0:24:26Spot on, you've found the difference in length between the two lines.
0:24:26 > 0:24:30Now to work out what a five-metre difference means over a 12-lap race.
0:24:33 > 0:24:38- You've got to do it 12 x 5. - Yep, that's the sum.
0:24:38 > 0:24:41Being able to multiply and divide numbers
0:24:41 > 0:24:46helps cyclists work out how many laps they have to cycle in any given race.
0:24:46 > 0:24:50Anyhow, back to the sum, 12 x 5.
0:24:50 > 0:24:54That means she's got to travel 60 metres more if she goes on the red line.
0:24:54 > 0:24:57Spot on!
0:24:57 > 0:24:58Right, done.
0:24:58 > 0:25:03Good work. 60 metres is a huge amount over a race.
0:25:03 > 0:25:04It's nearly a quarter of a lap.
0:25:04 > 0:25:09Sticking to the red line would add critical seconds onto Sarah's time,
0:25:09 > 0:25:13and could mean the difference between winning and losing.
0:25:13 > 0:25:16It's definitely worth sticking on the black.
0:25:16 > 0:25:19They did a top job measuring those lines,
0:25:19 > 0:25:24and calculating the difference between the lengths in record time.
0:25:24 > 0:25:28- And that difference again? - BOTH: 60 metres.
0:25:30 > 0:25:33The lads have completed their 3, 2, 1, Go! challenge,
0:25:33 > 0:25:36and cyclist Sarah Storey has their prizes.
0:25:36 > 0:25:39Congrats, guys, that was really, really good.
0:25:39 > 0:25:44I had absolutely no idea that I would go so much further in a race if I rode so far up the track.
0:25:44 > 0:25:46I'd like to give you a certificate,
0:25:46 > 0:25:52and also, hopefully this will be the first of many gold medals to come in your careers.
0:25:52 > 0:25:56Hang it somewhere proud, so you remember your day here at the velodrome.
0:25:56 > 0:25:59- So congratulations.- Thanks.
0:26:01 > 0:26:06OK, now your teacher has got a challenge for you. 3, 2, 1, Go!
0:26:10 > 0:26:13Sports people must be fast,
0:26:13 > 0:26:15strong,
0:26:15 > 0:26:17and deadly accurate.
0:26:19 > 0:26:24But did you know they wouldn't be able to compete without maths?
0:26:24 > 0:26:27Time keeping...
0:26:27 > 0:26:30scoring...
0:26:30 > 0:26:31speed...
0:26:31 > 0:26:34shape...distance.
0:26:34 > 0:26:36It's all mathematics.
0:26:36 > 0:26:40A tenth of a second or just a few millimetres
0:26:40 > 0:26:45can transform an ordinary person into a world champion.
0:26:45 > 0:26:48COMMENTATOR: Great Britain get the gold!
0:26:48 > 0:26:51- This is...- 3, 2, 1.- Go.
0:26:51 > 0:26:55- We take teams to a secret location. - This really is a special place!
0:26:58 > 0:26:59This is fabulous.
0:26:59 > 0:27:02To be given a behind-the-scenes tour...
0:27:04 > 0:27:07..and meet their sporting heroes...
0:27:07 > 0:27:10Hi, Jack, nice to meet you.
0:27:10 > 0:27:12..who'll give them a maths challenge.
0:27:12 > 0:27:163, 2, 1, go!
0:27:16 > 0:27:18- Go!- Go!
0:27:18 > 0:27:21And if they get it right...
0:27:21 > 0:27:2217!
0:27:23 > 0:27:27One, two, three, four...
0:27:27 > 0:27:31Probability suggests you should dive to the bottom right hand corner.
0:27:31 > 0:27:33..they win a gold medal.
0:27:35 > 0:27:38This challenge is all about gymnastics.
0:27:41 > 0:27:46Gymnastics is a sport that involves the performance of exercises,
0:27:46 > 0:27:49demonstrating strength, agility, and balance.
0:27:49 > 0:27:55Floor exercises take place on a mat measuring 12 metres by 12 metres.
0:27:55 > 0:28:01A performance must contain forward, backwards and sideways acrobatic elements, and a balance move.
0:28:01 > 0:28:06It must not exceed 70 seconds. And they must not step outside the lines.
0:28:06 > 0:28:08So, are you ready?
0:28:08 > 0:28:103, 2, 1, Go!
0:28:12 > 0:28:19Today, twins Heather and Beth are being taken to a secret location near Heathrow Airport
0:28:19 > 0:28:22to complete their 3, 2, 1, Go! challenge.
0:28:22 > 0:28:27They're really into gymnastics and know all about the ins and outs of the sport.
0:28:27 > 0:28:29There's a lot of elements to gymnastics.
0:28:29 > 0:28:33You've got, like, the trapeze, and you've got the balance beam.
0:28:33 > 0:28:37Heather loves to watch the gymnasts on the balance beam and bars,
0:28:37 > 0:28:40and is learning gymnastics herself at school.
0:28:40 > 0:28:43She really enjoys practising on the trampoline
0:28:43 > 0:28:47and her favourite move is the straddle jump.
0:28:47 > 0:28:50Heather's twin sister Beth loves the accuracy of gymnastics.
0:28:50 > 0:28:55You've got to be perfect, because if you do just one little thing wrong, you can lose a lot of points.
0:28:56 > 0:29:01Beth's favourite discipline to watch is rhythmic gymnastics with ribbons,
0:29:01 > 0:29:05but at school she really enjoys practising on the balance beam,
0:29:05 > 0:29:08and she has won sports day twice.
0:29:09 > 0:29:14The girls are so sports mad, they've been picked to be Olympic ambassadors at their school.
0:29:14 > 0:29:18We've always been involved in sport within our school.
0:29:18 > 0:29:20We're not necessarily the best,
0:29:20 > 0:29:23but they chose people enthusiastic about the Olympics wanting to do it.
0:29:23 > 0:29:26I'd have thought they'd have guessed where they're going by now.
0:29:26 > 0:29:29It's the Heathrow Gymnastics Club.
0:29:30 > 0:29:31Wow.
0:29:31 > 0:29:34Wow, indeed!
0:29:34 > 0:29:39The Heathrow Gymnastics Club is the UK's only official Olympic association training gymnasium.
0:29:39 > 0:29:42It's the largest gymnastics facility in England,
0:29:42 > 0:29:46and is the most successful British club across all disciplines.
0:29:46 > 0:29:50And this is where they're going to be given their 3, 2, 1, Go! challenge.
0:29:50 > 0:29:51That'll be good!
0:29:53 > 0:29:56For any gymnastics enthusiast, this is a real treat.
0:29:58 > 0:30:00You guys done any gymnastics before?
0:30:00 > 0:30:02We've done trampolining at school.
0:30:02 > 0:30:08This is where elite British gymnasts come to train.
0:30:08 > 0:30:10Wow, it's massive.
0:30:10 > 0:30:13It certainly is! Even though they've come for a maths challenge,
0:30:13 > 0:30:18the girls can't pass up a chance to train where some of the British Olympic team practise their stuff.
0:30:18 > 0:30:21First things first, warm up.
0:30:23 > 0:30:25Now, come on, girls - reach!
0:30:25 > 0:30:27Can't stretch that far!
0:30:27 > 0:30:31Now time for the bars. Chalk up.
0:30:35 > 0:30:37SHE LAUGHS
0:30:37 > 0:30:39And that's not bad at all, girls.
0:30:39 > 0:30:41- Thank you.- That's all right.
0:30:41 > 0:30:45Now time for Heather's favourite, the trampolines.
0:30:56 > 0:30:58Now, I'm afraid it's time to jump off
0:30:58 > 0:31:01and get ready for your maths challenge.
0:31:01 > 0:31:03And one of the British Olympic gymnastics team
0:31:03 > 0:31:07has taken a break in training to meet Beth and Heather
0:31:07 > 0:31:09and give them their challenge.
0:31:09 > 0:31:11- I'm Beth.- Hi, Beth. - I'm Heather.- Hi, Heather.
0:31:11 > 0:31:13Here's hoping he can tell them apart.
0:31:14 > 0:31:17Daniel Purvis became the world number one
0:31:17 > 0:31:20men's artistic gymnast in 2011.
0:31:30 > 0:31:34He's been the British all-round gymnastics champion twice.
0:31:34 > 0:31:36He won gold in the World Cup,
0:31:36 > 0:31:39and also got gold in the 2012 Test Event.
0:31:42 > 0:31:44What's your favourite sports then?
0:31:44 > 0:31:46Gymnastics and the diving and swimming,
0:31:46 > 0:31:50- I think they're the most precise ones.- All right, cool, good answer!
0:31:50 > 0:31:54OK, girls, we're going to have to crack on. Time for the challenge.
0:31:54 > 0:31:57My routines are full of somersaults and flips and spins.
0:31:57 > 0:32:00Can you work out where I'd be at different degrees of rotation?
0:32:00 > 0:32:02Three, two, one, go!
0:32:04 > 0:32:08So Beth and Heather have been given a rotation measuring challenge.
0:32:08 > 0:32:11I think you have to draw these angles.
0:32:11 > 0:32:16Angles that Daniel was at, at different points in his flips.
0:32:16 > 0:32:18Yep, you've got it.
0:32:18 > 0:32:20Heather and Beth have been given a list
0:32:20 > 0:32:22of three different degrees of rotation
0:32:22 > 0:32:25that Daniel's body will pass through in a 360 spin.
0:32:25 > 0:32:29Their job is to measure them out, and mark them on the board,
0:32:29 > 0:32:32using a protractor and a few pictures of Daniel.
0:32:32 > 0:32:35We've already put the first one down, to get the girls going.
0:32:35 > 0:32:39Daniel at 45 degrees in his spin.
0:32:39 > 0:32:41So now for the next one, 162 degrees.
0:32:41 > 0:32:43OK, so we need to get a picture of Daniel,
0:32:43 > 0:32:47and if you get the protractor and the pens.
0:32:47 > 0:32:50- OK, so if you measure 162 degrees. - OK.
0:33:01 > 0:33:03That's good measuring, girls.
0:33:07 > 0:33:10Shall we go from here?
0:33:10 > 0:33:12And just draw through the middle.
0:33:12 > 0:33:13There's the first one done.
0:33:13 > 0:33:15Perfect!
0:33:15 > 0:33:18Understanding rotation is really important for gymnasts
0:33:18 > 0:33:21when they are learning and perfecting spins and somersaults.
0:33:21 > 0:33:24They should know roughly whereabouts their body should be
0:33:24 > 0:33:26at these different degrees of rotations.
0:33:26 > 0:33:28So the second one is 239.
0:33:28 > 0:33:31That's right, girls. This one is a little tricky, though,
0:33:31 > 0:33:34because the protractor finishes at 180 degrees.
0:33:34 > 0:33:36But there's a way round it.
0:33:36 > 0:33:41First, find the difference between 239 and 180.
0:33:41 > 0:33:45- Take away 180 from 239. - Which is 59 degrees.
0:33:45 > 0:33:49Then reposition the protractor, so that it starts at 180,
0:33:49 > 0:33:52and mark from there the difference you calculated.
0:33:52 > 0:33:56We need to measure 59 degrees off the protractor.
0:33:59 > 0:34:01And there it is.
0:34:01 > 0:34:05- 180 plus 59?- 239.
0:34:05 > 0:34:11Try and stick this here, and draw the line through.
0:34:11 > 0:34:12Perfect.
0:34:12 > 0:34:16It's incredible to think Daniel's body goes through all of these degrees.
0:34:16 > 0:34:17Which one next?
0:34:17 > 0:34:20And the last angle is 324 degrees.
0:34:20 > 0:34:25This time, they need to find the difference between 324 and 180.
0:34:25 > 0:34:28That way, they can figure out where to mark the board,
0:34:28 > 0:34:30while holding the protractor in the new position.
0:34:30 > 0:34:36- 324 minus 180 degrees is...- 144.
0:34:36 > 0:34:39Oh, they're good! So round to 144 on the protractor.
0:34:39 > 0:34:43I'll just draw a straight line from the centre through.
0:34:43 > 0:34:48That's 324 degrees there from zero.
0:34:48 > 0:34:53That's right. 180 plus 144 makes 324.
0:34:53 > 0:34:55OK, get the last picture of Daniel.
0:34:59 > 0:35:01And we need to draw a straight line through.
0:35:04 > 0:35:07Amazing work. That was a tricky challenge
0:35:07 > 0:35:10and you completed it in record time.
0:35:10 > 0:35:14You managed to use the protractor to find specific degrees of rotation,
0:35:14 > 0:35:16and mark them up on the board.
0:35:16 > 0:35:20You also expertly used subtraction to mark up those bigger numbers.
0:35:20 > 0:35:24So take us through those degrees of rotation, girls.
0:35:24 > 0:35:30- 162 degrees.- 239 degrees. - And 324 degrees.
0:35:33 > 0:35:37Beth and Heather have completed their 3, 2, 1, Go! challenge
0:35:37 > 0:35:38and it's time for their reward.
0:35:38 > 0:35:40Great job today, girls, well done.
0:35:40 > 0:35:43Here's your medals, congratulations again.
0:35:43 > 0:35:46- Thank you.- Congratulations. - Thank you.
0:35:47 > 0:35:49Well done, great job.
0:35:53 > 0:35:56Now your teacher has a challenge for you. 3, 2, 1, go!
0:36:00 > 0:36:03Sports people must be fast...
0:36:03 > 0:36:05strong...
0:36:05 > 0:36:07and deadly accurate.
0:36:11 > 0:36:14But did you know they wouldn't be able to compete without maths?

0:36:30 > 0:36:34can transform an ordinary person into a world champion.
0:36:35 > 0:36:36Great Britain get the gold!
0:36:36 > 0:36:39This is...
0:36:39 > 0:36:40- 3, 2, 1.- GO!
0:36:40 > 0:36:43We take teams to a secret location.
0:36:43 > 0:36:45This really is a special place.
0:36:48 > 0:36:50This is fabulous.
0:36:50 > 0:36:52To be given a behind the scenes tour...
0:36:52 > 0:36:54THEY SCREAM AND LAUGH
0:36:54 > 0:36:57..and meet their sporting heroes.
0:36:57 > 0:36:58Hi, Jack, nice to meet you.
0:37:00 > 0:37:02..who'll give them a maths challenge.
0:37:02 > 0:37:063, 2, 1, go!
0:37:06 > 0:37:08- Go!- Go!
0:37:08 > 0:37:11And if they get it right...
0:37:11 > 0:37:1317!
0:37:13 > 0:37:171, 2, 3, 4.
0:37:17 > 0:37:21Probability suggests we should dive to the bottom hand right corner.
0:37:21 > 0:37:24..they win a gold medal.
0:37:24 > 0:37:27This challenge is all about rowing.
0:37:31 > 0:37:37All Olympic rowing races are 2,000 metres long with six lanes.
0:37:37 > 0:37:43The boat, or shells, can have one, two, four or eight rowers in them,
0:37:43 > 0:37:46and some have a cox to steer them.
0:37:46 > 0:37:50The rowers have either one or two oars each.
0:37:50 > 0:37:52They paddle together in a straight line,
0:37:52 > 0:37:56and the first to cross the finish line wins.
0:37:56 > 0:37:58So are you ready? 3, 2, 1, Go!
0:38:01 > 0:38:06Today, rowing fans Emma and Alanna are being taken to a secret location
0:38:06 > 0:38:08near the town of Maidenhead.
0:38:08 > 0:38:10They have no idea where they're going.
0:38:10 > 0:38:13Where are we going?
0:38:14 > 0:38:17There's a forest.
0:38:17 > 0:38:19They've both just started to learn to row.
0:38:19 > 0:38:21We started this school year.
0:38:21 > 0:38:25Rowing, not many people do, so it's a good skill for when you get older.
0:38:25 > 0:38:29They're not the best boats. The seats come off sometimes.
0:38:34 > 0:38:38Alanna has been learning to row at their school club.
0:38:38 > 0:38:41At school, she has won 42 sports medals,
0:38:41 > 0:38:43and because of her sporting achievements
0:38:43 > 0:38:47has been training at the Great Britain pentathlon camp.
0:38:47 > 0:38:52I like being on the water. So I like sailing, as well.
0:38:52 > 0:38:56Emma has also been learning to row at their school rowing club.
0:38:56 > 0:38:59She likes being out on the water so much,
0:38:59 > 0:39:01that she's also a qualified kayaker
0:39:01 > 0:39:03and a Level 3 Royal Yachting Association sailor.
0:39:03 > 0:39:06They do quite a few sports, actually.
0:39:06 > 0:39:10We do lacrosse, rowing, netball.
0:39:10 > 0:39:12- Swimming.- Rugby.- I used to do rugby.
0:39:12 > 0:39:15- Hockey, as well.- Pentathlon. - Rounders.- Surfing.
0:39:15 > 0:39:19- Tennis.- Gymnastics. I've done, like, everything.
0:39:19 > 0:39:20I like discus, as well.
0:39:20 > 0:39:23Phew! Well, they'll fit right in where they're going,
0:39:23 > 0:39:26because it's home to a huge variety of athletes.
0:39:26 > 0:39:29Bisham Abbey National Sports Centre, right on the River Thames,
0:39:29 > 0:39:33houses the UK's most elite athletes.
0:39:33 > 0:39:37All of the British athletes that won gold in the Beijing Olympics
0:39:37 > 0:39:41came through here, and it's where the GB Olympic rowing squads train.
0:39:41 > 0:39:43But it's not just them.
0:39:43 > 0:39:47Over 100 different British Olympic and Paralympic athletes
0:39:47 > 0:39:48are training here, too,
0:39:48 > 0:39:50from hockey to synchronised swimming.
0:39:50 > 0:39:55It's usually only the highest level sports people who are allowed in,
0:39:55 > 0:39:59but today, Alanna and Emma are going to be given special access.
0:40:00 > 0:40:03Hi, Alanna, hi, Emma, I'm Richard.
0:40:03 > 0:40:06Welcome to the English Institute of Sport at Bisham Abbey.
0:40:06 > 0:40:07Come in, I'll show you around.
0:40:09 > 0:40:11You're normally only allowed in this gym
0:40:11 > 0:40:13if you're in the top 15 in the world.
0:40:13 > 0:40:15Now that's exclusive!
0:40:15 > 0:40:17This is where the hard training happens.
0:40:17 > 0:40:20This is where the gold medals are earned.
0:40:20 > 0:40:24To earn those medals, the athletes train every day,
0:40:24 > 0:40:27lifting enormous weights to build their strength.
0:40:27 > 0:40:30The basic theory is we want to make sure that the rowers get stronger.
0:40:30 > 0:40:35And the stronger we can make the rowers, the faster they make the boat go.
0:40:35 > 0:40:37So this is one of the exercises rowers would do.
0:40:37 > 0:40:41This is really important to improve your back strength
0:40:41 > 0:40:46and making sure you can pull the oar through as strong as you possibly can, OK?
0:40:46 > 0:40:49I want you to pull up, so the chest hits the bar.
0:40:49 > 0:40:52That's it - perfect. See if you can do another one.
0:40:52 > 0:40:56Good work, Alanna, you'll be on the team in no time.
0:40:56 > 0:40:58Pull up till your chest hits the bar, that's it.
0:40:58 > 0:41:00So you can be working your back.
0:41:01 > 0:41:03Good, excellent.
0:41:03 > 0:41:05As well as all that weight lifting,
0:41:05 > 0:41:10the rowing team also has to train on the ergonomic rowing machines.
0:41:10 > 0:41:13And today the men's and women's Olympic teams are in a session,
0:41:13 > 0:41:15so the girls get to train with the best.
0:41:15 > 0:41:18All the rowers use the ergos every single day.
0:41:18 > 0:41:20We can see what is their maximum power,
0:41:20 > 0:41:24especially when you're looking at a race of 2,000 metres,
0:41:24 > 0:41:26and measuring how quickly they can do it.
0:41:26 > 0:41:28Dig deep, girls!
0:41:30 > 0:41:34But, of course, the real rowing doesn't happen on dry land.
0:41:34 > 0:41:37Just outside the training centre is the River Thames,
0:41:37 > 0:41:39where the rowing teams get out on the water,
0:41:39 > 0:41:42and put all of that training into practice.
0:41:42 > 0:41:44They're pulling in quite well.
0:41:44 > 0:41:46Their boat's nicer than ours!
0:41:48 > 0:41:49Getting ready - go!
0:41:51 > 0:41:53Today, one of the British Olympic rowing team
0:41:53 > 0:41:58has taken a break in her training to give them their challenge.
0:41:58 > 0:42:00- Hello.- BOTH: Hi. - I'm Anna. Nice to meet you.
0:42:00 > 0:42:03- What's your names? - I'm Emma.- I'm Alanna.
0:42:04 > 0:42:07Anna Watkins competes in the women's double scull.
0:42:07 > 0:42:13With that event, she has won the world championship,
0:42:13 > 0:42:17and also come first in the World Cup.
0:42:17 > 0:42:20And at the Beijing Olympics, she took home a bronze medal.
0:42:21 > 0:42:24You two are rowers, as well, is that right?
0:42:24 > 0:42:29- Yeah.- And whereabouts do you row? - In Reading, with our school.
0:42:29 > 0:42:32Oh, wow! I wish I'd been able to do rowing at school.
0:42:32 > 0:42:34It wasn't at my school, I had to wait till I was older.
0:42:34 > 0:42:40- What's your favourite bit about rowing?- Being on water.- Yeah.
0:42:40 > 0:42:42When you get it right there's nothing like it, is there,
0:42:42 > 0:42:46when you think, "Yeah, I did that," and you can't ever do it quite the same, can you?
0:42:46 > 0:42:50Yeah. Was it scary going to Beijing and rowing in the Olympics?
0:42:50 > 0:42:52Um, yeah, it was scary,
0:42:52 > 0:42:56because you knew that everybody was watching you on the telly,
0:42:56 > 0:43:00and you're in a really weird place. Like, China's obviously very
0:43:00 > 0:43:03different from England and the food was different,
0:43:03 > 0:43:05and lots of unexpected things happened,
0:43:05 > 0:43:07like, there were helicopters flying over during the racing,
0:43:07 > 0:43:10and we had to get used to it all.
0:43:10 > 0:43:14Right, enough of the chat, time for their challenge.
0:43:14 > 0:43:16In our training, we need to measure if we are improving.
0:43:16 > 0:43:19A good indication is to look at our stroke rate -
0:43:19 > 0:43:22a measure of how many times the team pull the oars in a minute.
0:43:22 > 0:43:25Measure the rower's stroke rate over three straights
0:43:25 > 0:43:26and plot them on a graph.
0:43:26 > 0:43:29Also, plot a line of the average rate.
0:43:29 > 0:43:32Did the team improve over the training session?
0:43:32 > 0:43:343, 2, 1, go!
0:43:38 > 0:43:41So the girls have been given a timing challenge,
0:43:41 > 0:43:44and we've got them as close to the water as possible
0:43:44 > 0:43:45without them having to swim.
0:43:51 > 0:43:55OK. We need to work out the stroke rate per minute for three strokes.
0:43:55 > 0:43:59- Mm-hm. I'll do the timing. - And I'll count. Pass me a pen.
0:43:59 > 0:44:02So they know what they've got to do.
0:44:02 > 0:44:04The team are out on a training session,
0:44:04 > 0:44:07rowing up and down straight lengths on the river.
0:44:07 > 0:44:10As the boat comes past them, they have to work out
0:44:10 > 0:44:13the team's stroke rate, which is the number of strokes
0:44:13 > 0:44:15they make in a minute.
0:44:15 > 0:44:17They need to take measurements for three different straights
0:44:17 > 0:44:22over the team's training session and plot them on a graph.
0:44:22 > 0:44:25Right, looks like the team are heading their way.
0:44:28 > 0:44:30- Go.- One...
0:44:30 > 0:44:33So, Alanna is timing a minute on the stop watch,
0:44:33 > 0:44:35while Emma counts the strokes.
0:44:37 > 0:44:40- 18.- Stop.
0:44:40 > 0:44:42- Write it down.- 18.
0:44:42 > 0:44:45Right. 18 strokes per minute was the stroke rate
0:44:45 > 0:44:48of their first straight. Not bad, they're warming up.
0:44:48 > 0:44:51- Are you ready for the next straight? - Go.
0:44:52 > 0:44:55It's really important for rowers to know their stroke rate,
0:44:55 > 0:44:58as it's a good indication of how fast they're going during a race.
0:44:58 > 0:45:03- If stroke rate increases, so should the speed.- 19, 20.
0:45:03 > 0:45:06- Stop.- OK, 20.
0:45:06 > 0:45:09And there's the second one - 20 strokes per minute.
0:45:09 > 0:45:14That's pretty good, but come on team, let's get to competition rate.
0:45:15 > 0:45:18It's really important to get a precise measurement,
0:45:18 > 0:45:21because in a race, every stroke, and every second, counts.
0:45:21 > 0:45:25- 26.- Stop.- 26.
0:45:25 > 0:45:27OK, 26.
0:45:27 > 0:45:31Wow! 26 strokes a minute - that's got to hurt!
0:45:31 > 0:45:37- OK, let's plot those results on the graph.- 1.- 18.
0:45:38 > 0:45:40So that'll be there.
0:45:43 > 0:45:462 is 20, so...
0:45:48 > 0:45:4926.
0:45:53 > 0:45:56- OK, now join them up, girls. - And this one.
0:45:58 > 0:46:00Lovely.
0:46:00 > 0:46:04So, what was their average rate across their training session?
0:46:04 > 0:46:07So, 18 plus 20, that's 38.
0:46:07 > 0:46:10Yeah, that's the total of the first two straights.
0:46:10 > 0:46:15Then 38 plus 26, that's 64.
0:46:15 > 0:46:17Great. So that's the total of all three straights.
0:46:17 > 0:46:20Now, what's next?
0:46:20 > 0:46:27We need to divide 64 by 3, so that's 21.3 recurring.
0:46:27 > 0:46:30That's a good job, girls. You've got the average stroke rate,
0:46:30 > 0:46:33and without a calculator and everything.
0:46:33 > 0:46:38- Now add that to the graph. - OK. So, 21 would be, like, there.
0:46:40 > 0:46:43So, do you think they got better during the session?
0:46:43 > 0:46:45Yeah, I think they did.
0:46:45 > 0:46:48because they started off at 18 strokes per minute, below average,
0:46:48 > 0:46:53and then they ended up at 26 strokes per minute, above average,
0:46:53 > 0:46:55so, yeah, I think they did.
0:46:55 > 0:47:00Looks like they got it right. They first measured three different stroke rates over the team's
0:47:00 > 0:47:02practice session and plotted them on the graph.
0:47:02 > 0:47:06They worked out the average - in their heads, no less - to prove
0:47:06 > 0:47:10whether the team's stroke rate improved over the session.
0:47:10 > 0:47:12- How did they do again, girls? - BOTH: They improved.
0:47:14 > 0:47:17They have completed their 3, 2, 1, Go! challenge,
0:47:17 > 0:47:19and rower Anna Watkins has got their prizes.
0:47:19 > 0:47:23Well done, as well, Alanna. There's your certificate
0:47:23 > 0:47:26and a very shiny medal. Good work!
0:47:27 > 0:47:29Top job, girls.
0:47:29 > 0:47:34Now your teacher has a challenge for you. 3, 2, 1, go!
0:47:39 > 0:47:44Sports people must be fast, strong,
0:47:44 > 0:47:46and deadly accurate.
0:47:48 > 0:47:52But did you know they wouldn't be able to compete without maths?
0:47:53 > 0:47:54Time keeping...
0:47:56 > 0:47:58..scoring...

0:48:13 > 0:48:15COMMENTATOR: Great Britain get the gold!
0:48:15 > 0:48:17This is...
0:48:17 > 0:48:19- 3, 2, 1... - Go.
0:48:19 > 0:48:21We take teams to a secret location...
0:48:21 > 0:48:24This really is a special place.
0:48:26 > 0:48:28This is fabulous.
0:48:28 > 0:48:31..to be given a behind-the-scenes tour...
0:48:31 > 0:48:32HE SCREAMS
0:48:32 > 0:48:33HE LAUGHS
0:48:33 > 0:48:36..and meet their sporting heroes...
0:48:36 > 0:48:39Hi, Jack, nice to meet you.
0:48:39 > 0:48:41..who'll give them a maths challenge.
0:48:41 > 0:48:453, 2, 1, go!
0:48:45 > 0:48:47- Go!- Go!
0:48:47 > 0:48:49And if they get it right...
0:48:49 > 0:48:5217!
0:48:52 > 0:48:56One, two, three, four.
0:48:56 > 0:48:59Probability suggests we should dive to the bottom right corner.
0:48:59 > 0:49:02..they win a gold medal.
0:49:04 > 0:49:06This challenge is all about rugby.
0:49:09 > 0:49:13Rugby union is played on a grass field up to 100 metres long
0:49:13 > 0:49:15and 70 metres wide.
0:49:15 > 0:49:18Two teams of 15-a-side try to get an oval-shaped ball
0:49:18 > 0:49:20to either end of the pitch.
0:49:22 > 0:49:28The ball can be kicked forwards, but only passed sideways or backwards.
0:49:28 > 0:49:33Five points are scored for a try, and a further two for converting it,
0:49:33 > 0:49:34and tackling IS allowed.
0:49:34 > 0:49:36So, are you ready?
0:49:36 > 0:49:393, 2, 1, go!
0:49:41 > 0:49:45Today, rugby fans Owen and Cameron are being taken to a secret location
0:49:45 > 0:49:51in Cardiff in Wales to complete their 3, 2, 1, Go! challenge.
0:49:51 > 0:49:53They both play for local teams,
0:49:53 > 0:49:58and Cameron has had some pretty important matches, even a cup final.
0:49:58 > 0:50:01All your family and that was there watching, like, me,
0:50:01 > 0:50:05so you've done something, you've achieved something.
0:50:05 > 0:50:08That's what it felt like when I walked onto the pitch.
0:50:08 > 0:50:11Cameron has been playing rugby for four years.
0:50:11 > 0:50:14He's a flanker in the scrum.
0:50:14 > 0:50:17He plays for Rumney and Cardiff Schools,
0:50:17 > 0:50:18and has won Player of the Year.
0:50:18 > 0:50:21Although the lads don't know where they're going yet,
0:50:21 > 0:50:24they're already looking forward to it.
0:50:24 > 0:50:25Yeah, should be good.
0:50:26 > 0:50:29Owen has also been playing rugby for four years.
0:50:29 > 0:50:31He plays the number eight position,
0:50:31 > 0:50:35so it's his job to bind between the locks at the back of the scrum.
0:50:35 > 0:50:38He plays for the Glamorgan Wanderers,
0:50:38 > 0:50:40and has won the Cardiff District Cup.
0:50:40 > 0:50:43And the boys have just seen where they're going.
0:50:43 > 0:50:48It's the Millennium Stadium, home to the Wales national rugby union team.
0:50:48 > 0:50:51Every year, it hosts their Six Nations home games,
0:50:51 > 0:50:53in front of 74,500 fans.
0:50:53 > 0:50:58It even has its own retractable roof to keep everyone nice and dry.
0:50:58 > 0:51:02This is where the boys are going to be given their 3, 2, 1, Go! challenge.
0:51:07 > 0:51:10Cameron, Owen, welcome to the Millennium Stadium.
0:51:10 > 0:51:14This is the entrance that only the players get to use.
0:51:14 > 0:51:16OK, so this is where the players come in on a match day.
0:51:18 > 0:51:22And the boys are being given a backstage tour.
0:51:23 > 0:51:26This is the Welsh home dressing room.
0:51:26 > 0:51:30And this is where all the favourite players come before a match.
0:51:31 > 0:51:33Got all the shirts lined up.
0:51:34 > 0:51:38- Can I keep one of the tops? - Oh, I dunno.
0:51:38 > 0:51:40- They won't mind. - Maybe if you get a cap you can.
0:51:40 > 0:51:42Yeah, nice try, Owen!
0:51:42 > 0:51:45The dressing rooms aren't just where the teams prepare for matches,
0:51:45 > 0:51:48they're also where they come to recover.
0:51:48 > 0:51:50At the end of the game, the players have got so many bruises
0:51:50 > 0:51:52and so much damage to their muscles,
0:51:52 > 0:51:55they need to have a bath full of ice.
0:51:55 > 0:51:58Imagine sitting in that, full of ice,
0:51:58 > 0:52:00for about two or three minutes.
0:52:00 > 0:52:02Could you imagine doing that?
0:52:02 > 0:52:04Um, no.
0:52:04 > 0:52:05HE LAUGHS
0:52:10 > 0:52:14This is where every Welsh rugby player dreams of walking out.
0:52:14 > 0:52:18Cameron and Owen get it all to themselves.
0:52:18 > 0:52:20There's only one word to describe it.
0:52:20 > 0:52:22Big.
0:52:24 > 0:52:26Big. I've never been on here, it's amazing.
0:52:28 > 0:52:32Today, two of the Wales national team have taken a break in training
0:52:32 > 0:52:36to give the boys their 3, 2, 1, Go! maths challenge.
0:52:36 > 0:52:38- OK, boys?- All right. - What's happening?- How's it going?
0:52:38 > 0:52:42- Nice to meet you. Harry.- Hi. - Harry, how's it going?- Owen.
0:52:42 > 0:52:45- Lloyd, hi.- Cameron. - How's it going?- Yeah, good.
0:52:45 > 0:52:49Lloyd Williams plays for the Cardiff Blues.
0:52:55 > 0:52:59He plays scrum half, so he makes many of the tactical decisions.
0:52:59 > 0:53:01He's earned six international caps,
0:53:01 > 0:53:04and represents Wales in the Six Nations.
0:53:06 > 0:53:10- What position are you? - Number 8. I'm prop.- How about you?
0:53:10 > 0:53:13- Flanker. Open side.- Open side.
0:53:13 > 0:53:15THEY LAUGH
0:53:16 > 0:53:21Harry Robinson loves playing at the Millennium Stadium.
0:53:23 > 0:53:25He plays on the wing.
0:53:25 > 0:53:29His team is also the Cardiff Blues and, at only 18,
0:53:29 > 0:53:33he's been selected as the youngest player in the Wales squad.
0:53:33 > 0:53:36- Who are your favourite players, then?- Um, probably Sam.
0:53:36 > 0:53:40- Sam, yeah.- Gethyn Jenkins, yeah.
0:53:40 > 0:53:43Flanker Gethyn Jenkins.
0:53:43 > 0:53:45Right, enough of the chat. Time to be given their
0:53:45 > 0:53:483, 2, 1, Go! challenge. Listen up, lads.
0:53:49 > 0:53:51Here you go boys, here's your task.
0:53:51 > 0:53:53Your team has just scored five points for a try under the posts.
0:53:53 > 0:53:56You get another two points for a successful conversion.
0:53:56 > 0:54:00From a given spot on the pitch, how far will you need to kick the ball
0:54:00 > 0:54:02in a straight line before it just clears the crossbar?
0:54:02 > 0:54:043, 2, 1, go!
0:54:04 > 0:54:10So the boys have been given a formulaic and measuring challenge.
0:54:10 > 0:54:13They need to work out how far the ball will travel in a straight line
0:54:13 > 0:54:18from a given spot on the pitch, to where it just clears the crossbar.
0:54:18 > 0:54:20They're being given the height of the bar,
0:54:20 > 0:54:23but the other two sides of the right-angled triangle are missing.
0:54:23 > 0:54:28So, we've got to try and get that ball over the post.
0:54:28 > 0:54:32We know the height of the bar, so we need to work out this length here
0:54:32 > 0:54:35to find out how we're going to kick the ball over the post.
0:54:35 > 0:54:38We're going to have to use Pythagoras for that.
0:54:38 > 0:54:40Good thinking, Cameron.
0:54:40 > 0:54:44Right. Now to measure the bottom length.
0:54:44 > 0:54:47Two, three...
0:54:47 > 0:54:51Pythagoras's theorem, said to have been deduced by a Greek philosopher
0:54:51 > 0:54:55and magician over 2,500 years ago, has been helping people work out
0:54:55 > 0:54:57the lengths of the sides of triangles ever since.
0:54:57 > 0:55:01They can't measure the length of the longest side - the hypotenuse -
0:55:01 > 0:55:03directly, so they're going to have to work it out by knowing
0:55:03 > 0:55:06the length of the other two sides.
0:55:06 > 0:55:0715.
0:55:08 > 0:55:12It's 15 metres, so write 15 metres in there.
0:55:12 > 0:55:16So, we know that's 15 metres.
0:55:18 > 0:55:21Now we need to find out this, so if we use the ruler.
0:55:21 > 0:55:22Draw the line.
0:55:26 > 0:55:28From here to the ball.
0:55:28 > 0:55:31OK. They've got the measurements, now to apply the formula.
0:55:31 > 0:55:33We need to name the sides first, so...
0:55:36 > 0:55:38Oh, well done.
0:55:38 > 0:55:40C.
0:55:40 > 0:55:43So, they know the lengths of the sides A and B,
0:55:43 > 0:55:47so what's the equation to find out C?
0:55:47 > 0:55:50Then we can write A squared.
0:55:50 > 0:55:53A squared.
0:55:53 > 0:55:56Plus B squared...
0:55:56 > 0:56:00equals C squared.
0:56:00 > 0:56:05That's right, Pythagoras's theorem is A squared plus B squared
0:56:05 > 0:56:07equals C squared.
0:56:07 > 0:56:09Oh, I love a bit of Pythagoras with my rugby!
0:56:09 > 0:56:14And we're going to need to substitute the numbers, then, for the letters,
0:56:14 > 0:56:18- 3.6.- 3.6.- Squared.
0:56:18 > 0:56:23Yeah, 3.6 is the distance between the crossbar and the floor.
0:56:23 > 0:56:26Plus 15 squared.
0:56:26 > 0:56:3115 is the distance the boys measured from the ball to the goalposts.
0:56:31 > 0:56:35- Equals.- Equals... - OK. So, do the maths.
0:56:35 > 0:56:403.6 squared = 12.96.
0:56:40 > 0:56:4412.96.
0:56:44 > 0:56:46And 15 squared equals?
0:56:46 > 0:56:48225.
0:56:48 > 0:56:55- So what's next, boys? - So, 12.96 plus 225 equals...
0:56:57 > 0:57:02237.96.
0:57:03 > 0:57:05So, that's going to be C squared.
0:57:05 > 0:57:13C squared equals 237.96.
0:57:13 > 0:57:16Then you have to do the square root of that to get the answer of
0:57:16 > 0:57:21the distance from the ball to the post.
0:57:21 > 0:57:27So, the square route is 237.96 is...
0:57:27 > 0:57:30Oh, no, hold on, don't tell me. I can do this in my head.
0:57:30 > 0:57:3715.43.
0:57:37 > 0:57:39Yes, I knew that. I knew it.
0:57:39 > 0:57:45So, the distance is 15.43 metres.
0:57:46 > 0:57:50It looks like they've got it right, and to two decimal places as well.
0:57:50 > 0:57:54First, they realised that, in order to find the distance the ball
0:57:54 > 0:57:57would travel, they needed to use Pythagoras's Theorem.
0:57:57 > 0:57:59They were already given the height of the bar,
0:57:59 > 0:58:02which they labelled A, then they expertly measured
0:58:02 > 0:58:05the length along the grass, which they called B.
0:58:05 > 0:58:08To find the missing length, C, they applied the formula
0:58:08 > 0:58:11with deadly accuracy, by adding the squared values
0:58:11 > 0:58:15of the two known sides, then finding the square root.
0:58:15 > 0:58:17Easy!
0:58:17 > 0:58:19So what was the distance again?
0:58:19 > 0:58:22BOTH: 15.43 metres.
0:58:22 > 0:58:26Now, they can clear the bar with maths, but can they with a boot?
0:58:29 > 0:58:32Oh, yes! He scores!
0:58:32 > 0:58:34Congratulations, Cameron. Well done, mate.
0:58:34 > 0:58:37The boys have completed their 3, 2, 1, Go! challenge
0:58:37 > 0:58:40and Lloyd Williams and Harry Robinson have their prizes.
0:58:40 > 0:58:43- There's your medal.- Thank you.
0:58:43 > 0:58:44Well done, boys.
0:58:44 > 0:58:46Now your teacher has a challenge for you.
0:58:46 > 0:58:47BOTH: 3, 2, 1, go!
