"@B_Holmer Cool - although it's always been a popular strategy in running to focus on efforts near race pace in the last [--] weeks before the race. It makes sense to optimize the specificity when peaking for performance. It doesn't necessarily mean that it's the best strategy all year round"

"@SimonCirnski I like the HR histogram much more informative than the three zone bins Despite most of the training nominally being in the "green zone" you can see that it actually accumulated around the mod/heavy boundary. Very little easy/recovery riding"

"@gregmushen @B_Holmer Further I don't believe it is possible to get extraction to 90% by low-intensity exercise alone even if you do hours of it. You will need to activate and stress more than some type I fibers to build oxidative capacity+capillaries in all the motor units you use at VO2max"

"Something to consider for athletes who suspect they are prediabetic based on a HbA1c test: elite and professional cyclists had higher HbA1c but lower fasting glucose than sedentary people. In highly trained cyclists increased exercise intensity is linked to lower fasting glucose but slightly higher HbA1c. This suggests that while training improves short-term glucose control it may influence long-term markers differently. https://t.co/5YxOf2VZAS In highly trained cyclists increased exercise intensity is linked to lower fasting glucose but slightly higher HbA1c.

"@jem_arnold @Jamie_langley1 Cool analysis Since the value is not a single breath but already an averaged value from the mixing chamber (10s) the first point doesn't apply (raw data from a MC is quite smooth). Nice investigative work on the peak power. With low economy + long steps a plausible VO2"

"@jem_arnold @mrOLEZZ @JeroenSwart @kristianblu @science2sport The latter; the system has an algorithm to match flow with gas concentration. Assuming a fixed delay time will make BxB correct in a pretty narrow range of breathing frequencies resulting in an overest. at low and underest. at high Bfs.

"@jem_arnold @mrOLEZZ @JeroenSwart @kristianblu @science2sport Some BxB systems have an adaptive delay time that changes with the Bf. Those might be more accurate (not Cosmed). I still trust mixing chamber better for VO2max measurements (of course not for VO2 kinetics etc). It's more robust with fewer assumptions and hidden calculations"

"@bowtiedcheetahh @caesar_data Thanks for the summary One comment thought: the fatigue at the end of a marathon etc. would not be captured by this simple MPA model since it assumes that MPA stays intact below CP.
