Document Summary
Knes 303 lecture 18 strategies to optimize exercise prescription and maximize health related benefits. Maximizing physiological adaptations: exercise training with a small muscle group, single-leg cycling or leg-extension, single leg has a very high capacity to increase local vo2max without having much of an effect on whole body. Implications: single-leg exercise compared to double-leg exercise can be sustained at a higher percentage of the double-leg vo2max, this may lead to a greater local metabolic stress that may favor greater peripheral adaptations compared to double-leg exercise training. If the aim is that to maximize the time at vo2max work intervals longer than 2 min with recovery of the same duration should be used (1:1-0. 5 work: interval ratio) -> 4min:4min or 4min:2min. If the intervals are shorter than 2 minutes, we are most likely not attaining vo2max, even if there was some priming. 1:1 may be the best approach (equivalent time on and off)
