0:00:53 > 0:00:55# Oh, yeah! #
0:00:57 > 0:01:01Oh, hello, there. I'm just experimenting with some flavours
0:01:01 > 0:01:03to make a fresh fruit salad. Yum, yum.
0:01:03 > 0:01:05BEEPING
0:01:05 > 0:01:09I hear a beep, I see a flash. I wonder what they're going to ask.
0:01:12 > 0:01:14- BOTH: Hi, Nina!- Hi.
0:01:14 > 0:01:19- We've got a question for you. - What do sport players eat and drink?
0:01:19 > 0:01:23That's a great question. What do sports players eat and drink?
0:01:23 > 0:01:27Many sports players use up lots of energy running around
0:01:27 > 0:01:29or concentrating on winning their game.
0:01:29 > 0:01:34So what they eat and drink can make a huge difference to their success.
0:01:34 > 0:01:37Why don't you come down to my lab and we'll investigate?
0:01:37 > 0:01:40See you soon, Nina. Bye!
0:01:40 > 0:01:43Bye. Well, I'm going to need some help to answer this one.
0:01:43 > 0:01:47I know just who to ask. OK, Neurons, time to get to work.
0:02:02 > 0:02:05ALL: Neurons at the ready, Nina.
0:02:05 > 0:02:09OK. Today's question is, what do sports players eat and drink?
0:02:09 > 0:02:13Which Neuron will be most useful to help find the answer?
0:02:13 > 0:02:15ALL: Me! Me! Me! Oh, me!
0:02:15 > 0:02:18Will it be fabulous Felix?
0:02:18 > 0:02:22I can help so very much if you need the sense of touch.
0:02:22 > 0:02:24Will it be beautiful Belle?
0:02:24 > 0:02:26I send messages to brain from ear.
0:02:26 > 0:02:29If there's a sound, I'll help you hear.
0:02:29 > 0:02:30Will it be lovely Luke?
0:02:30 > 0:02:33For looking and seeing, day or night,
0:02:33 > 0:02:35I'll help you with your sense of sight.
0:02:35 > 0:02:37Will it be awesome Ollie?
0:02:37 > 0:02:40If it's pongy or whiffy but you can't tell,
0:02:40 > 0:02:42my messages help your sense of smell.
0:02:42 > 0:02:43Or will it be baby Bud?
0:02:43 > 0:02:46Sour, salty, bitter or sweet,
0:02:46 > 0:02:48I'm your taste buddy whenever you eat!
0:02:51 > 0:02:54- It's Bud.- Yippee!
0:02:54 > 0:02:55CHEERING
0:02:55 > 0:02:58- OTHERS CHANT:- Go, Bud! Go, Bud! Go, Bud!
0:03:03 > 0:03:05Give me a taste of the action, Nina.
0:03:05 > 0:03:09Today's question is, what do sports players eat and drink?
0:03:09 > 0:03:13We taste when we eat and drink, so Bud will be helping us today.
0:03:13 > 0:03:17I need to get the lab ready before the experimenters arrive.
0:03:19 > 0:03:23Ayesha loves spaghetti. Samiyah likes playing card games.
0:03:23 > 0:03:25Athletes look really fast.
0:03:25 > 0:03:28Boxers look really muscly.
0:03:28 > 0:03:32But they both want to know, what do sports players eat and drink?
0:03:32 > 0:03:34So today, for one day only,
0:03:34 > 0:03:38Samiyah and Ayesha become the experimenters!
0:03:40 > 0:03:42- Hi, guys.- BOTH: Hi, Nina.
0:03:42 > 0:03:45Welcome to my lab and thank you for your great question -
0:03:45 > 0:03:48what do sports players eat and drink?
0:03:48 > 0:03:50To find out, let's start by using our senses.
0:03:50 > 0:03:53ALL: Whoop, whoo! A senses experiment.
0:03:53 > 0:03:55We're ready, Nina!
0:03:55 > 0:03:58First, let's have a think about our favourite foods.
0:03:58 > 0:04:01- So what do you like?- Potato.
0:04:01 > 0:04:03Spaghetti.
0:04:03 > 0:04:05Ooh, spaghetti, potatoes.
0:04:05 > 0:04:08I had some delicious fruit salad earlier,
0:04:08 > 0:04:11and I've also got some of my favourite foods here.
0:04:11 > 0:04:14These are healthy foods which are good for our bodies.
0:04:14 > 0:04:17But why is that? Let's get experimenting.
0:04:17 > 0:04:22OK, look at this cool little fan.
0:04:22 > 0:04:24Now, I wonder if it'll move on its own.
0:04:24 > 0:04:27Let's see if it's got a battery.
0:04:27 > 0:04:32No, no battery. But it's going to need energy to make it move.
0:04:32 > 0:04:35What about using potatoes?
0:04:35 > 0:04:38Did you know that you can make a battery using a potato?
0:04:38 > 0:04:39BOTH: No, Nina.
0:04:39 > 0:04:41OK, experimenters, watch this.
0:04:47 > 0:04:49- Hey! - NINA LAUGHS
0:04:49 > 0:04:52Yes. Potato power worked.
0:04:52 > 0:04:54NEURONS: Hooray. It worked. Yeah!
0:04:56 > 0:04:59So this little fan needs energy to move.
0:04:59 > 0:05:02By connecting all these wires,
0:05:02 > 0:05:05it's able to get energy from our special battery.
0:05:05 > 0:05:08We are just like this little fan.
0:05:08 > 0:05:10Our bodies need energy to move.
0:05:10 > 0:05:12But we're not connected to a battery,
0:05:12 > 0:05:16- so how do you think we get our energy?- From eating food.
0:05:16 > 0:05:18Yes, eating food like potatoes
0:05:18 > 0:05:21gives our body the energy it needs to work.
0:05:21 > 0:05:24So do sports people need more energy, Nina?
0:05:24 > 0:05:26Interesting question, Felix.
0:05:26 > 0:05:29People who do very active sports like running,
0:05:29 > 0:05:33football or rugby, they use up a lot of energy,
0:05:33 > 0:05:37so they need to eat very regularly to power their bodies.
0:05:37 > 0:05:39So our bodies get energy from food.
0:05:39 > 0:05:44And the more exercise we do, the more we need to eat.
0:05:44 > 0:05:46Do sports players eat the same thing, Nina?
0:05:46 > 0:05:48That's a great question.
0:05:48 > 0:05:52Well, to find out more, let's go and watch some fast action.
0:05:52 > 0:05:53I know just the place.
0:05:57 > 0:06:01Oh, goody. I love this bit. I wonder where Nina is taking us.
0:06:01 > 0:06:04Nina mentioned finding some fast action.
0:06:04 > 0:06:08Perhaps it's a car rally with oily petrol smells.
0:06:08 > 0:06:11And speedy racing cars.
0:06:11 > 0:06:12BUD IMITATES CAR
0:06:12 > 0:06:14It's noisy, but I don't hear cars.
0:06:16 > 0:06:19I promised you guys some fast action,
0:06:19 > 0:06:22so let's watch these fantastic rugby players in action.
0:06:28 > 0:06:32What do you notice about the size and shape of the rugby players?
0:06:32 > 0:06:35- Some look really strong. - Some look smaller.- That's right.
0:06:35 > 0:06:40A successful rugby team is made up of a mixture of shapes and sizes.
0:06:40 > 0:06:44Some players are small and fast, so they can run with the ball.
0:06:44 > 0:06:46And some players are big and muscly
0:06:46 > 0:06:49so they can stop the other team from getting the ball.
0:06:49 > 0:06:54- Do they all eat the same food, Nina? - That's a great question, Bud.
0:06:54 > 0:06:57Let's go and meet a couple of players to find out.
0:06:57 > 0:07:00Experimenters, this is Jordan and Sam.
0:07:00 > 0:07:02- KIDS: Hello. - All right, guys?
0:07:02 > 0:07:04Jordan and Sam play for the same rugby team,
0:07:04 > 0:07:07but what do you notice about their sizes?
0:07:07 > 0:07:10- Jordan is much bigger.- That's right.
0:07:10 > 0:07:12Jordan does a lot of pushing in rugby,
0:07:12 > 0:07:14so it helps to be big and muscly.
0:07:14 > 0:07:19Sam does lots of running, so it helps to be smaller and lighter.
0:07:19 > 0:07:23Guys, we're trying to find out what sports people eat and drink.
0:07:23 > 0:07:26- Is this the food you would eat when you're training?- Yes.
0:07:26 > 0:07:29- I'd eat most of these foods every day.- Yeah, me too.
0:07:29 > 0:07:34- Especially when I'm training. - That's a lot of food.- It is, Luke.
0:07:34 > 0:07:36Jordan and Sam do a lot of exercise,
0:07:36 > 0:07:39so they need to eat a lot of food for energy.
0:07:39 > 0:07:41But it's different types of food.
0:07:41 > 0:07:43So let's do an experiment.
0:07:43 > 0:07:47We've got different food in different coloured bowls.
0:07:47 > 0:07:50The red bowls are for proteins.
0:07:50 > 0:07:54The yellow for carbohydrates and the green bowls are vitamins.
0:07:54 > 0:07:58What I want you to do is to sort the bowls into each type of food.
0:08:09 > 0:08:11My goodness.
0:08:11 > 0:08:16Well done! Now, what do you notice about Jordan's food?
0:08:16 > 0:08:18Jordan has more red bowls.
0:08:18 > 0:08:22- Is that right?- Yes, Nina. I eat lots of meat, eggs, cheese and fish.
0:08:22 > 0:08:25They're all foods which are high in proteins,
0:08:25 > 0:08:28which help to build muscles. That's ideal for Jordan,
0:08:28 > 0:08:33who needs to be big and strong to push other players in a rugby game.
0:08:33 > 0:08:36- What about Sam's food? - He has lots of yellow bowls, Nina.
0:08:36 > 0:08:39Yes, I eat lots of bread, pasta and rice, Nina.
0:08:39 > 0:08:41They're all carbohydrates,
0:08:41 > 0:08:44which give us lots of energy that lasts a long time.
0:08:44 > 0:08:48So they're ideal for Sam, who does lots of running around.
0:08:48 > 0:08:53Oh, so different food helps sports players do different things.
0:08:53 > 0:08:55Yes. Well done, Bud.
0:08:55 > 0:08:58But what about the food in the green bowls?
0:08:58 > 0:09:01They're full of vitamins. So who eats those?
0:09:01 > 0:09:03- Both of them, Nina.- That's right.
0:09:03 > 0:09:07Both Jordan and Sam eat plenty of fruit and vegetables
0:09:07 > 0:09:09because they're really important.
0:09:09 > 0:09:13They keep their bodies working well. But it's the same for all of us.
0:09:13 > 0:09:16If we eat a variety of all these foods,
0:09:16 > 0:09:19we should have lots of energy to do everything we want to do,
0:09:19 > 0:09:21including playing rugby.
0:09:33 > 0:09:35Thank you. Bye.
0:09:36 > 0:09:37BOTH: Bye, guys.
0:09:38 > 0:09:40Nina needs a drink.
0:09:40 > 0:09:42You're absolutely right, Bud.
0:09:42 > 0:09:46Exercise does make us thirsty, and there's a very good reason why.
0:09:46 > 0:09:50I know a great experiment that'll help to explain.
0:09:50 > 0:09:52This is Peter. He's a rugby player.
0:09:52 > 0:09:56He's going to help us find out why we get thirsty when we play sport.
0:09:56 > 0:09:58- Hi, Peter.- Hi, Nina. Hi, guys.
0:09:58 > 0:10:00BOTH: Hi, Peter.
0:10:00 > 0:10:02Peter, are you feeling thirsty right now?
0:10:02 > 0:10:05No, I've had quite a lot to drink this morning.
0:10:05 > 0:10:09Peter, we're going to weigh you to find out how heavy you are
0:10:09 > 0:10:11when you're not thirsty. On you go.
0:10:11 > 0:10:14- What does it say, experimenters? - 83.5.
0:10:14 > 0:10:17That's right. 83.5kg.
0:10:17 > 0:10:20That's what he weighs when he's had plenty to drink.
0:10:20 > 0:10:24But we want to find out if his weight is any different
0:10:24 > 0:10:26when he gets thirsty.
0:10:26 > 0:10:28We know that we get thirsty when we exercise,
0:10:28 > 0:10:32so Peter is going to do some fast cycling in this very hot room,
0:10:32 > 0:10:34and we'll see what happens.
0:10:52 > 0:10:54What do you notice about Peter's face?
0:10:54 > 0:10:56- He looks hot and sweaty.- Yes.
0:10:56 > 0:10:59It's normal to sweat when you exercise,
0:10:59 > 0:11:03but because Peter's in this special hot room, he's sweating even more.
0:11:03 > 0:11:06- He's working very hard. - You're right, Felix.
0:11:06 > 0:11:09But Peter is specially trained to do this experiment.
0:11:09 > 0:11:14You should never try this at home. I think that's long enough.
0:11:14 > 0:11:18Well done, Peter. Thank you so much. How are you feeling?
0:11:18 > 0:11:20I'm tired and thirsty, Nina. NINA LAUGHS
0:11:20 > 0:11:24I've got a drink of water here, but before you take a sip,
0:11:24 > 0:11:28can we weigh you again, please? Thank you.
0:11:28 > 0:11:31Now what weight is he, experimenters?
0:11:31 > 0:11:3382.2kg, Nina.
0:11:33 > 0:11:39Wow. 82.2kg! Peter, you can have a drink of water now.
0:11:39 > 0:11:43So Peter's weight went down 1.3kg during that experiment.
0:11:43 > 0:11:46Is that because he's sweating, Nina?
0:11:46 > 0:11:50Yes, it was, Belle. Our bodies have lots of water in them,
0:11:50 > 0:11:53and when we sweat, we lose water through our skin.
0:11:53 > 0:11:57So Peter has lost a lot of water through sweating today,
0:11:57 > 0:12:01so he needs to drink lots of water to replace what he's lost.
0:12:01 > 0:12:04But drinking water is good for us all the time.
0:12:04 > 0:12:07- No matter what we're doing. - Exactly, Neurons.
0:12:12 > 0:12:17So your question was, what do sports players eat and drink?
0:12:17 > 0:12:19I think we've answered it.
0:12:19 > 0:12:21Our bodies need food for energy.
0:12:21 > 0:12:24Different types of foods are good for different things.
0:12:24 > 0:12:29Exercise uses energy, makes us sweat and lose water.
0:12:29 > 0:12:32So it's important to drink plenty of water...
0:12:32 > 0:12:34Whether you're exercising or not.
0:12:34 > 0:12:37So I hope that's answered your question.
0:12:37 > 0:12:40BOTH: Thanks, Nina. Bye.
0:12:40 > 0:12:42You're welcome. Bye.
0:12:42 > 0:12:46If you want to know more about the science that's all around us,
0:12:46 > 0:12:49go to the Nina section on the CBeebies website. Have fun.
