Does heart rate actually relate to performance?
I recently started using an HRM, I am pretty slow on the bike, may max was 195 and my resting pulse is 40-45 (I am 36). Theoretically these are pretty good figures and I do most of my riding at zone 4+, still not very fast!
Physiologically my heart must have quite good stroke, and my blood must be carrying sufficient oxygen, otherwise my resting HR would be high. This combined with the relatively high max I should be awesome………..unfortunately this doesn’t seem to translate to reality 😥
