Document Summary
Knes 303 lecture 10 prescription of exercise (using hr) part ii po/speed (characterizing/prescribing exercise intensity) Cooling vest: cooling vest to limit the increase in body temperature during the warm-up phase, video: summer heat can have an impact on performance, which the cool vest can help with. Its like a cool pack with gel inside that freezes when you put it in a freezer: keeps your body cool during warm-ups gives a small advantage in terms of keep core temperature lower. This occurs no matter what whether the intervals are long or short, etc. High blood flow still occurring to get rid of co2, deliver substrate, etc. If recovery periods are kept constant in duration (and not based on hr returning back to original baseline), hr will never return to original baseline. As exercise bouts go on, the duration of recovery needed to return to original baseline will progressively increase with more bouts (until exhaustion).
