 Welcome to Film My Run, I'm Stephen. Here we are again in Eastbourne for another session on the monstrous Woodway treadmill at the Welkin Sports and Exercise Physiology Labs at Brighton University. We're going to do a second round of testing, so let's get in there and see how we get on. So, right, what we've got to do first is take a load of testing at rest. So, blood glucose, so I'm going to get my blood taken in a second, lactate, and then I'm going to breathe into a gas chamber and that'll measure my oxygen and my carbon dioxide levels at rest. And then I'm going to run on the treadmill and every 15 minutes I'm going to have to drink a fluid. I'm not allowed to know whether it's placebo or whether it's real carbohydrate solution and then more gases taken and more bloods taken every 15 minutes. Helen, what's the difference between the testing we did the other day and today's testing? Absolutely nothing. So, what's the reason for doing two lots of testing? To see the difference between a glucose and fructose mixture on endurance performance between the placebo as well. So, no sugar versus sugar. Okay. So, basically they're just testing whether on a long distance run, hour and a half's worth of running, whether I am oxidising fat or burning carbohydrate and if it's a placebo, how much does my glycogen level drop? How much fat am I oxidising to fuel my run? Now, I've got to drink six of these. Right, they're going to increase the treadmill speed to 11 km per hour. We're at 1% incline. So, now we just have to run for 90 minutes. Every 15 minutes we stop. Okay, time for first gases. Having done gases whilst I'm running, I now get bloods taken and I have to rate myself. You know what? I'm going to go to 12 already. No GI discomfort at all. So, I've got to measure GI discomfort from like up here, like lungs, chest kind of thing and then down here stomach and now second drink. Okay, so we are 28, 29 minutes in. Nearly time for the second lot of gases, bloods and drink. 11 km an hour still. Heart rate's about 138. So, I'd say RPE is still 12. I'm kind of settling in now. Zero, zero. So, it takes a good couple of minutes to do these little bits of testing. 42 and a half minutes in. Eight kilometers run according to the stride foot pod and we're just coming up to gases, bloods and drink number three. If you remember from the last testing video just the other day, I noticed that if I change my cadence on this treadmill the speed increases according to the stride foot pod. So, remember we're on a medical grade massively expensive wood weight treadmill. There's not going to be a lot of belt slippage or slow down on impact of my foot. So currently the wood weight treadmill is reading 11 km an hour and has been for the whole time. Stride is currently telling me 10.7 km an hour. Now by adjusting my cadence and my stride length I'm going to show you on Zwift down here that you can increase the speed of the stride even though the treadmill remains at the same speed. Right, so what's my cadence currently? 170. 170. So I'm going to increase it to over 200 and let's see what happens to my speed. Would you look at that? 11 km an hour. What's my cadence? Cadence is 208. 208 steps per minute and we're running at 11 km an hour according to the stride. But there's another thing. I'm going to slow my cadence right down. I'm going to lull. Watch what happens now. What's my cadence how? 136. Cadence of 136 and I'm at 11.4 km an hour. That's a normal cadence. This is my normal natural running pace. Cadence rather. And we dropped back down to 10.7. How bizarre is that? Right 56 minutes in. Distance is 10.5 km according to stride. So we're just coming up to, is this third or fourth? Fourth drink, fourth gases, fourth bloods. This is exactly one hour in now. Half an hour to go. Drink number four. I've just rated myself at 12 on the RPE scale, which is somewhat hard. Sweating a lot, you can see. But we are indoors with no fan or anything. Go for it. Whatever you're ready. Do you want? 18 minutes in. I've done nearly 14 km, which is nine miles. Eight and a half. Right, we're just coming to the end. 10 miles completed on the treadmill. Last gases. Right, we're done. Last bloods. So I've basically rated that GI of zero for the whole thing and RPE 13 on the scale, which is somewhat hard. Because I'm absolutely soaking in sweat. Absolutely soaked. Okay, just saved my run on Zwift. Already uploaded to Strava. I'm looking at the percentage of oxygen and carbon dioxide in the air you've just expended. So the air that I've just breathed is in one of those bags. Yeah? Yeah, in this bag here. And then we need to basically record it for a minute because it takes a certain amount of air out. So we've got it for exactly a minute. So this machine is analysing the amount of carbon dioxide versus oxygen in my breath. Is that right? Yeah. Okay. And basically the result of that will tell you how much, whether I'm burning carbs or whether I'm burning fat as fuel. And so is this the last time you're going to get me in for testing on this project? On this project, it's the last time, but I might get you in for another one. So does this mean that you can tell us what the results of the two days testing are? Not yet. Not yet, okay. I need to analyse all the data first and then I'll be able to. Okay. Right, so all of you who were waiting for results of that, you're not going to get any. So Hallam's got to go away and analyse the data and then he'll email me with the results of it at some point. But at least you know what's been happening. But if you know me, you know I do ultra marathon distance races, long distance. And I think that I am more fat adapted. So I am more used to using my fat stores on long run than I am taking lots of sugary drinks and carbohydrate stuff. But it'd be interesting to know whether those drinks were carbohydrate or whether just placebo solution and whether I do indeed burn fat efficiently. Thanks, Hall. Thanks, sir. And that's it. Thanks very much for watching. Hope you enjoyed all that testing. Hopefully I'll manage to get some results from that in the next few days. Take care. See you again for another film I run. Bye.
