I Trained Like Lando Norris For 24 Hours

This is Lando Norris, a multiple Formula One race winner and one of the fittest athletes on the planet. And I'm Matt Amos, and I don't go to the gym. But for the next 24 hours, I'm going to attempt the same pre-season training that Lando does in order to race in Formula One. So I've come to the exact same training camp that Lando uses to see how an average guy stacks up to a Formula One driver. Happy to be here. That's okay, that's okay. What we do over here is we typically have drivers sent to us where we go for a comprehensive testing battery, ascertain their physiological capacity to determine whether they are ready to tolerate the demands of racing and apply their skills in their driving, but also to inform their training. I'll be doing seven challenges in my 24 hours, starting off with my full body assessments. We're going to start with your dexascan whole body x-ray. The amount of x-ray that then hits the sensor is depicted by the density of the tissue that the x-ray has passed through. And with those scans, it'll show me my body fat percentage, my muscles, connective tissue, and of course, my skeleton. The scan looks good, good quality. You've managed to stay still so far, so well done. But I wasn't expecting the scan to show everything. Oh no, you can't see my cock! We don't look at that, don't worry. What we're seeing here is the distribution of tissue throughout the body. Blue is lean mass, green, yellow, or red, that's body fat. So your body fat percentage is 22.3%. That's not that bad. It's not, honestly. So if you're between 10 and 20% and you're happy and healthy at your weight, you're relatively happy with that. Here we can look at bone mineral density, so that's a marker of bone health. And low bone mineral density is one of those markers we can use to determine whether someone's under-fuelling. So if someone's not eating properly, eventually that might manifest into low bone mineral density. So yours is pretty good. In and around the average, so on this figure here, the population average for males across the lifespan. So the white dot is you, and you're sat pretty much bang on where you need to be. In the left leg, you've got just under 9 kilos of lean mass, and in the right leg you've got just over 9 kilos. Asymmetries in training can increase your risk of injury. And this difference between my legs we'll see have a negative impact on my tests later on. But on to my next body assessment where we're finding out what my resting metabolic rate is. It's the amount of calories that you burn if you just lay completely still for 24 hours. We can estimate that from the gases that you breathe in and breathe out. This reminds me of like, ET. You might be wondering why trainers are needing to know the resting metabolic rate of an F1 driver. Well, after 30 minutes of lying down and simply breathing, this machine can show how many calories my body burns when I'm just resting. This can then be combined with the calories I burn during the exercise and physical activities I'm doing today to give an accurate picture of my calorie intake requirements from my diet, which of course is extremely important for Formula 1 drivers. Right on the border of like, oh I could actually, I could go to sleep. 17 to 1900 calories. For most drivers it's just about maintaining a stable weight, so I mean that's quite important that they know what their weight's going to be from a day-to-day basis. The next assessment, really quick, we are assessing something called your vestibular oculomotor function. So it gives us an idea of balance and posture. So just try and keep the dot in the centre of the screen at all times, alright? I'm going to lie, this is quite cool. This is like the first time I've ever done VR. A field of dots has appeared in front of you. We want you to pick any dot in the field, so follow the dot until it leaves your field of view and then pick a new dot and just continue over and over. We want you to look at the dot, the dot will then fade away, but we want you to maintain your gaze where the dot was, okay? With my body assessment all completed with no signs of any problems, it was then time to move on to the physical challenges. These are only going to get harder as day goes on and I had no idea how brutal it was going to be. So to make sure I don't injure myself, Christian guided me through an extensive warm-up, which even that was a bit of a struggle. That's it, and push right up and in. It was then time for the jump test, which to me looked really easy, but honestly, this one was humbling. For the purpose of the next assessment of the ability of your lower limbs, we typically break this down into braking force on the way down and propulsive force on the way up. Monitoring your adaptation to your gym programme over time, it also relates to a driver's ability to hit the brakes hard. What we are using are force plates, we've got a left and right leg and that relates to looking at asymmetries as well. The grey line is your total force, that's telling us your body weight in newtons. It's going to be a short dip and drive, followed by a land. Breathe out on the jump up. It will help you produce a bit more force and just get a bit more stability. Excellent, good start. We have jump heights in centimetres, then we also have watts per kilo, so that's your total power output. Probably a bit lower than what you're used to seeing. It's just a start, you won't go... It's going to be lower, mate, it's fine. That's it, that's a game. The jump was good. OK, good, so technically well executed. If you've jumped 24 centimetres with two legs, in theory you should be able to do actually more than 12. So, from here. And then when you feel ready... It feels so pathetic. It feels like you're hardly... Doing everything, yeah. OK, and relax. OK, so we've got seven. The hardest part for me was trying to maintain my balance whilst also trying to push down on the ground. Really push, extend the leg, almost like pushing off the ground. But no matter how much I tried, I was just really struggling with my left leg. However, when it came to my right, I did find that a bit easier. OK, good. 13, OK, so it's interesting that so far you have quite a deficit between left and right than we'd typically like. So, with it confirmed that my right leg is stronger than my left, this would mean I would need more training on the leg responsible for me trying to hit the brakes correctly in an F1 car. But from my off-balance position to now challenging my maximum strength. The isometric mid-fight pull. A static position, push as hard and as fast as you can for approximately five seconds. Three, two, one, and then relax. That's going to be three to five seconds, and we're going to get a live force trace. So, pound for pound, we can see how strong you are. Here we go, mate. Great, here we go. So, in a quarter squat position, lovely. So, we're just going to move this a bit higher. God, even after doing the warm-up, I can feel it storming the back of my legs. Really? OK. That's a bad sign, man. Yeah. Three, two, one, go. Push, push, push, push, push, push, push, push, push, push, push, push, push, push. And relax. That's an indication of how loud I'm going to be shouting at you. That's great, I love that. A couple of things that we're looking for in the force trace, your peak force output. So, how high are we getting with the trace? But the second thing is linked to something called your rate of force development. How quickly are you producing it? For that, we're looking for this initial increase in the force to be as steep as possible. Bang straight up, hold, down. I felt it, and then I was like, OK, I can push more. And then you can see that. And you can see that on the trace, can't you? You get there and then you pull up and work up to your maximum force. All right, you ready? Yeah. Full effort. Big deep breath, and then we're going. Three, two, one, go. Push, push, push, push, push, push, push, push, push, push, push, push, push, push. Good. I got the initial hit and I felt it going up a bit more. You can see it there, it's like the curve is going up towards the beginning of it. So, what may have similar to the jumps is having what we call pre-tension. Posture is there, your grip's nice and tight, and then from there, it's, you know, so you have a steeper gradient. So, should I try one more by like fully tensing everything to try and like get rid of like that jagging sort of curve at the beginning? OK, cool. So, for this one, I'll just tense up, get myself in the mindset. Right. Tense up. Tense up, nice big deep breath. Three, two, one, go. Push, push, push, push, push, push, push, push, push, push, push, push, push, push. Good, mate, good. There we go. Oh, there we go, yeah. All by tensing up, yeah, yeah. There we go. Nice. Well done, Matt. Fantastic. That initial gradient is really good and really steep. You've held your peak. So, that is the best representation of your maximum strength if you engage in a 12-week strength training programme. You'll see this change. Like if you're just tensing, there was no jagging or anything. It's kind of like you're already engaged and just you... Just on that from the technique, that's insane. We're probably more looking to anything above 35 to 40 is a pretty good score. And look, I know I wasn't going to get anywhere near the same strength as Lando, but I'm taking this test as a win. Also, my wrists are completely gone. I see, exactly. But now we're moving on to one of the hardest tests out of the entire day. This is now time for the gruelling three-minute test. This test requires an all-out sprint effort right from the get-go. The key is that you can't let off at any point. You won't know how much time has elapsed. The point of that is to eliminate pacing. We want to empty, if you like, what we call your finite energy capacity in the first two and a half minutes. And we're taking the average speed of your last 30 seconds, which will be taken as what we call your critical speed. It gives us a goal standard, an accurate indicator of the capacity of a driver with floor-rate stress and strain from the demands of an F1 driver, but also allows us to be very precise in prescribing their interval training. GPS units, you don't have one but two, so there's no hiding. All right, okay. So they are measuring you to roughly 10 times a second. At any point, we'll be able to get what we call a velocity time trace, and we'll get your signature of your all-out effort. So the data from your GPS unit is going to transfer to the Apple Watch. Oh, sick. And we'll be able to get your current speed, your maximum speed, and your heart rate. I'm here to, like, give it everything. So I know it's grey, it's starting to spit with rain, but I'm good for it. Brilliant. I love the mindset. That's what we want. Good to go for it. The key is do not stop all-out sprint effort. You can't let off at any point. Now, I was incredibly nervous about this test. I am absolutely shitting myself, by the way. As this was going to be the most physically draining exercise I've ever done. I mean, the last time I did a sprint race was back when I was six years old, and that was only for 20 seconds. I couldn't even get the practice start correct. One, two, three, go again. Sorry, I missed it already. But to now be sprinting as fast as I can for three minutes, I was pretty sure of myself that I couldn't make it to the end. So Christian gave me a great warm-up to try and give me the best possible chance I can have. The reason why we're doing this is because we need to make sure what we call your local motor muscles, calves, hamstrings, are at risk for injury if you're not either prepped or warmed up properly. Right, ready to go? Let's do it. Go on. The utmost admiration for anyone who does this, because it's hard enough for the athletes themselves. So now the time had come for me to try out my three-minute all-out sprint test. For me, I know I'm going to be watching this back later, being like, oh, I could have given it some more, give me some more. So that's why I'm like, no, I need to give it everything now. I've got my number one fan over there in the grandstand cheering me on. He's not looking at me at the moment, but he will eventually. What I'll do, I'll count you down, three, two, one, and then on the whistle, okay? Yeah. No. Three, two, one. Let's go. Let's go. Let's go, Matt. Push, push, sprint. Let's go. Give it all out. Push, push, push, push, push. Let's go. Okay, I'm already flying a bit. Keep going, Matt. Come on, open up. Good. Let's go. Drive around the corner. Let's go. Drive around the corner. Let's go. Let's go. Let's go. Come on, Matt. Keep pushing. Keep pushing, Matt. Come on. Really good, mate. Come on. Keep going now. Come on, Matt. Keep pushing. Come on. All-out effort. Come on, keep going. Really good, Matt. Excellent. Keep going, Matt. Let's go. Push around the bend, Matt. Let's go. Give it all you've got, Matt. Let's go. Push, push, push. Come on, Matt. Keep going. Come on. Keep pushing, Matt. Go, Matt. Go, Matt. Go, go, go. Keep going, Matt. Come on. Doing really well. Got to keep pushing. Come on. Keep pushing. Don't stop. Keep going. Keep going. Keep going. Don't stop. Okay? Sorry. That's okay. That's okay. Oh, ****. Oh, I really wanted to do it. Yeah, when I got around there, I fully, like, everything was out of the tank. Felt like my last reserves coming in. I can feel something gargling up a bit. Don't worry. Take your time. Don't do that. Oh, ****. Don't have to. God damn it. Imagine a flab there. It just went super wobbly, and I was just a bit like, I'm just crumbling down. Don't worry about it, Matt. I tried. I tried. I really tried. So, unfortunately, I didn't pass the test, but now we're moving on to the most recognizable Formula 1 exercise, the neck. Now, most people, when they see Formula 1 drivers do their fitness, a lot of it is through the neck, through hard braking, extreme G-forces in order to just keep their little bobble head kind of stayed in the cockpit the entire time. Today, we're going to use the Gatherer Systems harness. So you'll have seen this used by a lot of drivers that are on the F1 grid, who are often using the GS. We're going to attach the GS to a load cell, and that is basically going to connect with our laptop and tell us what your force outputs are as we're testing your maximal strength. Formula 1 drivers, what sort of, like, load are they able to get up to? Like, let's say their absolute maximum. 45 kilos upwards. You can see upwards of, like, 60, 65 kilos in some of the guys that have got particularly big necks. Where do you reckon I'm going to be here today with no neck training of any kind? 25, 30 kilos would be a really good score. Really good score if you could get to that. You need to have the right equipment to be able to do these kind of exercises. So I'm really intrigued, after seeing it happen for so long, how it's actually going to affect and how it's going to go. Whenever we test the neck, we're always very protective of it. We don't want to jump straight into maximal effort. So we're going to make sure we get your neck nice and warm. So you want to be able to brace against the bed. Here, chin tucked in, shoulders back, always looking forward at me, okay? This is such a weird perspective to see you from. Generally, it's like, it's really, really weird. Hold that position, okay? So I'm just going to apply a little bit of force. You ready? Yeah. For the warm-up session, we're using a 5kg resistance band. And as this is my first time, we're both trying to gauge each other of how much Joe needs to pull to how much I'm needing to resist moving in order to hold a neutral position. Feel that a bit more? Yeah, it's nice. So we're going to go for a few more where I'm going to pull now. This is going to be a bit harder now, okay? All of this warm-up was getting ready for our main test later on, but we still needed to work the different sides of my neck before we even get to that. As the warm-up continues, we wrap around the resistance band to get more of an immediate and controlled feel, creating a more realistic feeling to the maximum strength test we're building up to. Feel okay? Yeah, I feel like I can do more, which is cool. That's good because we're only warming up. Yeah. When I put my hands on my neck, I can feel the heat coming off. So obviously, it's warming up. And we went through various exercises to warm up my neck from different directions. The front pull is to replicate the braking going into a corner and the sides to act as the forces of driving around corners, which for drivers and myself, found the hardest to maintain. Good, well done, Matt. Tough? No, it's good. I really like this one. It's really good. Oh, this one's harder. Good, well done, mate. Good job. A bit harder that time? That one was a bit harder, yeah, but it's still really nice. I will try and gradually build up the load, but we're looking to get you there within about two to three seconds. We're somewhere probably around 10 to 12 kilograms. Okay. And we're just going to try and get there between me and you based on feel. So then you can get a feel for me applying the load and I can get a feel for you resisting. So now that my neck has warmed up, it's time to find out what the maximum strength is. Joe connects the load cell onto my neck harness and then from his laptop, he can add on more and more weight. To measure my maximum neck strength, they applied an increasing opposing force whilst I was trying to keep my head completely still until I could no longer hold on to it, which will then mark what is my maximum neck strength. We started off at what we thought 25% of my maximum opposing force was as a warm up and increased it until we found my limit. Go, so just maintain that position for me. Maintain, maintain, maintain, maintain, maintain. Good, there. Shall we go into a 50% effort? Okay, let's do it. Let's do 50%. You ready? Yeah. Three, two, one, go. So just hold that position. Hold, hold, hold, hold, and relax. A little bit closer to max, maybe 80% roughly. I'll guide that. If it does go bad, it's literally just me going... All right, let's try a little bit stronger then, Matt. You ready? Let's do it. Three, two, one, go. So push, push, push, push, push, push, push, push, push, push, push, push, push. Good. So that was just over 20 kilos. Oh, come on, let's go. So what did I say? 25, 30 would be a good score for you. So shall we try a maximum effort? Let's go for it. Yeah? Let's do it. Three, two, one, go. Push, push, push, push, push, push, push, push, push. Oh, dang it. Good. You did the right thing, so you dropped the force when you felt like it went a little bit too quick. What do you reckon that was? 23, maybe? 26.4 seconds. Really? I feel like I could go again. I think you could. All right, three, two, one, go. Push, push, push, push, push, push, push, push. What do you reckon that one was? I think maybe 26. It was 26 again. Oh, okay, well, there we go then. All right, Matt. Three, two, one, go. Push, push, push, push, push, push, push, push. 26.9. That is consistent, is it? It doesn't lie. I mean, your peaks are literally overlapping there. Wow. Well done, mate. That's pretty good. Happy with that? Yeah, very good. And we'll go 50%. Three, two, one, go. Push, push, push, push, push, push, push, push, push, push, push, push. Good, well done, mate. 90, and then we'll do a max. Three, two, one, go. Push, push, push, push, push, push, push, push, push, push, push, push. That wasn't far off max, was it? I'm definitely pulling more of a face now. I can't help it. I could feel the strain as I was applying that pressure. It's that little like, mmm. Three, two, one, go. Push, push, push, push, push, push, push, push. 20.58. So now that we have found out what is the maximum amount of strength I can hold on different sides of my neck, it's now time to put it into practice for a workout. This is the same workout that drivers will be doing throughout the entirety of the season. Similar to how a driver might use this in their hotel room, for example, or if they were doing training anywhere in the world, in gyms, whatever. Hook up to a door and generate the force themselves rather than someone apply the force to them. So we're going to look at you anywhere between 10 and 11 kilos. We're looking for you to hold for as long as you can. Okay. Until you cannot physically keep the position. We'd be looking for anywhere between about 90 seconds to 120 seconds. So there's going to be a line on here. It should be at around 10 or 11%. Get the blue line up to the black trace line. Just hold it there. Three, two, one. Okay, go. So let's go up to the black line and hold there at the black line. So up. What you can see me intensely looking at on the laptop is that blue line moving up and down. That's representing the amount of pressure I'm pulling against the door, which has a maximum amount of 10 kilograms. And my goal is to hold it for as long as possible until I cannot do it anymore. Very good. Don't go too high. That's it. Keep us around 10. Very good. Well done, mate. Come on, keep going. Let's dig deep now. Come on, let's not lean. Let's keep that a neutral position. Come on, back up nice and straight. Come on. I was really starting to struggle here. All I wanted to do was just make it to 90 seconds, no matter if I was in pain. Keep holding there at 10. Not too much leaning. Keep a nice straight back for me. Hold at 10. Come on, keep going. Come on, Matt. Keep going. Keep going, mate. Come on, keep going. Dig deep now. Come on, come on. Dig deep. Come on. Keep pushing. Come on, mate. Keep pushing. Try not to lean too much. Come on. Hold that position. Very good, mate. Come on, keep going. Come on, mate. Keep going. Right to the end now. Come on. Right to the end. Come on, Matt. Really good effort, this. Come on, keep pushing, buddy. Keep going, mate. Come on, Matt. Keep going. Keep pushing, mate. Keep pushing. Come on, right to the end now. Come on. Well done. I'm sorry. There's no sorry about that. That's a super low bar. I've let you down, Joe. You OK? Yeah. God, that was really hard to, like, hold it. I could feel I could give it more power, but then it was going too high, so then I was like, I need to bring it low. Yeah. And then it's like, I don't want to be too low. It's kind of like constantly trying to jump it up a little bit. Yeah, especially when you're new to it as well and it's not something you're familiar with. Yeah. It's hard to gauge how much force to apply to it. The shouting and the encouragement definitely helped. It was around about here, I was in Ghana, and that's when you were like, It does work. Some people don't like it. Some drivers don't need it. Some drivers prefer not to have it. This is such insane tech. I just never knew something like this, like this, like, even existed. We can use this data to construct the most effective neck training program for the driver, but in the same way that you wouldn't just whack on any weight plate on your bar, you'd always know what you're putting on. You should also know the load being induced through the neck. So we want to make sure we can measure that and therefore prescribe that precisely and optimally and safely. More than one minute 16. You got further than the three-minute test. You have to identify where your strengths are. Yes, yeah. I was so happy with myself that I was able to achieve this, especially after my disappointing results from early in the day. But we still have two more challenges left, which are designs that seriously make me sweat. I've now got a heart rate monitor. Basically, they're going to be increasing the speed every minute, but then just keep going until I die. And that's how it's going to go. Next up, we have your incremental ramp test running at six kilometers an hour. Yep. We're going to increase the speed by half a kilometer an hour every minute, and that's going to go until you reach what we call volitional fatigue, which is you can't go anymore. It also allows us to calculate something called your gas exchange threshold. The way in which we use data from the three-minute test that we did earlier today, where we determined your critical speed, and from your ramp test today where we're doing your VO2 max and your gas exchange threshold, it allows us to differentiate different exercise intensity domains where we'd prescribe recovery runs and low-intensity, long-distance runs for athletes. Half a kilometer every minute until you stop, and then it's straddle. It's a steady build-up, and all of a sudden, you'll realize you're finding this quite hard. And what's the top speed we're going to go to, potentially? That's up to you. Oh, OK, great. Three, two, one, go. Oh, OK. That's a lot easier than I thought. OK, so a nice steady start. OK, so we're going to increase half a kilometer. It's like I'm walking and really angry. It's a little bit awkward for a couple of minutes. You don't know if you want to run or walk. So we're going to increase again. The first few minutes of this test I found rather simple, to be honest. The speed's slowly increasing every minute that we go. OK, so we're going to increase again, Matt. Really good. Looking really strong, mate. In fact, when I used to go to the gym, this used to be how I used to start out my workout. A couple of seconds. We're going to increase again to 10.5. But here you can kind of see it in my eyes where I realize I can't just have a quick drink of water like I was in the gym. I had to just keep pushing through. Let's dig in now, mate. Come on. Really, really good. Come on. Right to the end. And at the 10-minute mark, my throat was so dry. I really wanted some water, and I couldn't stop looking at the timer. OK, we're going to increase again. So let's adjust to this speed. Come on. Adjust to that speed. Come on, Matt. Keep turning them legs over. This is where it counts now. Come on. Excellent work. Well done. I really wanted to get to the 12-minute mark, but here my throat was starting to collapse in, and I just couldn't take it anymore. Done? All right. Well done, mate. Well done. Big, deep breaths for me. I really wanted to get to 12. I thought you were going to get there as well. You were looking strong. Well done, mate. Nice, big, deep breaths. Whenever you're ready. You don't have to do it now. Just keep your legs turning over on that treadmill for me, all right? I know it doesn't look much at home, but obviously this has all been heavily cut down. I'm not just saying that, but it gives you appreciation that when you're seeing Lando or any F1 driver running around a track and being pushed to the max, it can look really easy. But trust me, this is ******* brutal. VO2 max-wise, you're sitting somewhere around 41 to 42 milliliters per kilogram per minute. Drivers will range somewhere between 50, 55 up to about 60, 65. Wow. So they're really fit. Milliliters in terms of like? Oxygen. Okay, yeah. The amount of oxygen that you can take in and use in a minute. Okay. And it's an indicator of your aerobic capacity. So mine's 41, 42. Yes. See, my first thought would be like, oh, is it lung capacity? But I'm guessing not. It's down to the psoriac, everything else. It's down to lots of things. Oxygen, carrying capacity of the blood, delivery, down to mitochondrial capacity in the muscle and being able to actually use the oxygen. It's a whole system of breathing it in, getting it into the blood, distributing it in the blood and using it at the muscle. Okay, so just nine off. Glass half full. But if I wasn't sweaty enough already, this last test is going to really push me to the limit. Many a great racing driver has sweated in this room and I will now be joining them. We're going to look at a number of your thermoregulatory responses whilst you're in the chamber. So we'll start with whole body sweat rate, which will take nude body mass measurements pre and post. And that will give us an indication of how much you've sweat. We'll then look at more local sweat rates. So we can look at the individual sweat glands that are firing within a given area, which is specific to the back and the forearm. In addition to that, we'll look at changes in your skin temperature. And we'll expect to see increases in skin temperature as you're exercising in the heat. And then finally, we'll also take some perceptual measures. So we'll be asking you how hot you perceive the environment to be and how comfortable you are at that heat. Nice. So first of all, then, it is the nude scaling. So basically, I'm assuming it's just to basically kind of work out how much water I've sweated off. Exactly that. Okay, cool. Right, so off to the changing room, dog. Go. Come with me. Okay, I'm fully in the nude. Time to turn on the scales. One, five. Yeah, one, five, one. Okay, cool. Time to go sweat it all off. First thing we'll do is put some ECG electrodes on. So they're going to go on for us to monitor your cardiovascular responses. That basically then allows us to calculate heart rate. And we can look at how those cardiovascular variables kind of respond when you're in the heat. And we'll get you into the chamber. And we're going to fit the skin thermistor, chest, bicep, calf, and thigh. And then we've got two capsules that are going to go on your back and forearm. They're going to draw up the sweat that's coming out of that very localized area. So this is the final test. So far we've identified the deficit between my legs, which was then proven during the jump test. Determining what my aerobic capacity and my training speeds were. The maximum I can push with my arms and pull on my neck. And work out how much oxygen I can take in and use within a minute. All this key data is exactly what a Formula One driver needs pre-season. Which can then form into the most precise exercise routines and dietary requirements. And for the final test, all I need to do is just cycle for 30 minutes in a hot chamber. Set at 40 degrees to monitor the amount of sweat loss I have. Giving an indication of my typical sweat loss when exercising in the heat. Which can either help prepare drivers or facilitate their recovery when they get out of the car. I'm going to give you a knock on the window when I want you to start cycling. Okay? Here we go. Okay, so we're constantly monitoring Matt's thermo-physiological responses while he's in the chamber. From the outside. On this laptop here we're monitoring his skin temperature. So we get traces for the four sites that we're measuring his skin temperature on. And we can monitor that increasing as his time in the chamber continues. And on a similar note here, we're monitoring his local sweat rate. So we can see roughly the point at which the back and the forearms start to increase with the sweat output. As he's starting to get hotter and therefore trying to cool down. On the Ventus here, there's two things we're monitoring. Firstly, his VO2 response. So we're measuring the amount of oxygen he's taking in and using. And that is specifically to make sure that he's working at the exercise intensity that we've set him at. And on the right hand side of the screen we're monitoring his cardiovascular responses. So from the ECG trace we're looking at his stroke volume, cardiac output and heart rate. We have him on there for 30 minutes. That's more just for timing purposes. We've got a lot to fit into two days or in Matt's case one day of testing. We'd usually look to go for about 60 minutes on the bike in the chamber. To get really good insightful data around thermoregulatory responses to the exercise and the heat. So we're actually starting to see the skin temperature rise a little bit now. Arm here, thigh here and chest here are now just starting to increase the left forearm sweating. So we're seeing that distribution of blood to the skin surface. Okay mate, so I just want to take a measure of your perception of the environment. So first and foremost thermal sensation. So from minus four very cold to four very hot. Can you just point to roughly how you feel this environment to be? Cool, thank you mate. So slightly warm. Within this heat how comfortable do you feel? From very uncomfortable to very comfortable. Again just point to a rough idea. Very comfortable. Okay, cool. One of our main heat dissipation avenues is what we call evaporative heat loss. Which we generally refer to as sweating. So we're seeing that distribution of the heat to the skin surface. And then it's going to start to evaporate via sweating. The exercise here is fairly moderate. It's the environment that's the challenging part. So the heat and the humidity in there is what makes it particularly difficult. Okay Matt, that's you done buddy. All good? Very sweaty there buddy. How do I look? Warm. How do you feel? Good. I know this sounds a bit funny but I do generally take line bikes all the time when I'm in London. So I didn't find this as bad as the others. Once you kind of got into a groove of it, it was like not bad. But then eventually just after like... I can see on the timer when it was getting towards the 30 minute I was a bit like... A bit of fatigue is kicking in now. Well done. Great effort. Appreciate it. Let's get your post body mass measurements and then you can have some water and shower and relax. I'm like so much cuter out here. Right. Be right back. My new weight, 14.9. So that's somewhere where we'd expect it to be. We see probably anywhere between about 0.6 and 1. The interesting case with motorsport is that sweating isn't necessarily that much of a beneficial thing. When they're in the full race suit, the skin surface is completely covered. Any evaporative heat loss through sweating doesn't kind of effectively cool the body as much as it would be when you're in this position where you're able to evaporate heat loss. So knowing things like that about people from this test allows us to help them prepare properly in terms of acclimation, pre-rate hydration and things like that. So you look like you were operating at somewhere around 160 beats per minute heart rate from the cardiovascular data. So indicates you're finding it fairly difficult, which is absolutely fine. It's the end of a long day in a very hot environment. Mate, well thank you ever so much for today. I really do appreciate it.
