He hasn’t been on that many podcasts and the Tymewear ideas were relatively new. He is talking about respiratory muscle training and breath rate during efforts. He used to have his athletes use an expensive Swiss medical device called a Spirotiger which has been discontinued. He’s found now that with the Tyme vest (I guess they don’t sell the vest anymore) and cheaper breathing devices he could produce similar results.
I know some may think this sounds like BS. I think there is something to it. It’s basically endurance training the diaphragm and intercostals and any other involved muscles. I know the Swiss mountain bikers (Shurter and co) used the Spirotiger. I’ve read about XC skiers also using it. Ancillary muscles fatiguing has been showing in studies using NIRS. But like I said, it’s probably the last 2% of performance.
I have no reason to doubt that there’s some possible gains there. I just don’t think it matters for most people. The more I wrap my head around this, I think, the value is giving you a more complete picture of where you are strong vs not. FTP says here’s your number and leaves it up to you to guess at what that means for your training. It works but Tyme lets you see that you can use some work in these specific zones and are already strong here. I see some value there although I wonder how it compares to the Wahoo 4D thing.
I think it’s just a different tool. People love to be able to spout an FTP number but it’s often not really representative of the power numbers/durations around that. And even, say, a 4DP test provides numbers depending on how fresh you are that day.
I think the power numbers you can hit in training are affected by how tired you are. Train to a particular VE number and it will have the same effect each day regardless of how tired you are. The power numbers will change (could be more or less) but hit the right VE number and you will be training the right physiological effect rather than blindly trying to hit power numbers.
Completely agree although that did send me a down path of do you even need to rest based on that philosphy? Obviously you do but if it basically just auto adjusts, why?
Good point I think you would still get to a point where the legs will just hurt too much to even turn pedals at a sufficient rate. And all the other bodily systems and parts that need to recover.
I ended up getting a bit of a lesson in this but slightly unintentionally. What happened is that I wanted to target my mid-week rides to endurance zone which for me was 43-50ve. Because it’s cold and rainy I did a 100km Zwift ride on Sunday that was upper tempo to Vo2 max. Garmin said 96 hour recovery. Monday I rested then Tuesday I did endurance range VE which translated to 110 watts. Wednesday the same workout was 118 watts. Thursday I did Vo2 max. Friday I did another endurance zone and it was 155 watts. Each of those three had an avg 47ve but the power jumped dramatically.
I could imagine the 8 watts difference but the difference between 110 or even 118 and 155, that’s massive!
How did it tally with perception of effort?
I’ve had the breathing sensor seriously under read on outdoor rides when wearing winter clothes compared to just a jersey on the turbo or in warmer weather outside. Differences of a few watts day to day in the same environment/clothing depending on freshness/fatigue.
I mean I have no particular way of knowing for sure if it’s misreading but the timeline does track with expected recovery and 150 ish would be upper end of my endurance zone if all things were optional. Seemed like it was recovery status driving breathing efficiency although I suppose the sensor could just be wrong.
Hi All - I created an app that uses statistical modeling to analyze the Vtialpro’s ventilation data to determine intensity. I designed it specifically for running, but it can be applied to any endurance activity, including cycling. In fact, the models used for the app mostly come from studies on cycling.
The value of the device is you can find/track your VT1/VT2. this allows you to anchor your zones to your energy system transitions, not some proxies.
Ventilation is a better metric to track as it responds quicker than HR and is more stable than HR over time. Some day your HR is higher or lower and you may not know why.
I’m aware of that. The question is would you expect to see that swing across power for the same minute ventilation as I recovered during the week? To me it makes perfect sense but others here are questioning it.
I think you would still get to a point where the legs will just hurt too much to even turn pedals at a sufficient rate. And all the other bodily systems and parts that need to recover.
