the capacity of muscle to take up and utilize O2 exceeds the ability of the heart to pump blood, such that VO2max is primarily limited by convective O2 delivery.

This has been and is my understanding also.

But why do 80% of people say they stop the ramp test because their legs get tired, and only 20% say it’s due to heart/breathing reaching the limit? Need to HTFU?

What is the reason you stop the ramp test?

For me, it’s my heart can’t beat any faster - how about you? poll ————————————- Edit: added question: Can any information be gleaned from why people fail the ramp test to inform the sort of training they should do or avoid? Or set expectations on the response to training? E.g. can muscle endurance/utilization of oxygen be more readily trained than cardiac output/oxygen delivery? ——————————————- Edit: addition of study on max HR and reasons for stopping: These are some interesting stats In…
