Document Summary
Heat: exercise in a hot ambient temperature places the body under greater physiological strain than exercise of the same intensity in temperate conditions. Exercise performance is often impaired in the heat: increased body temperatures linked to cv, neuromuscular, metabolic, immunological, and perceptual alterations that can cause premature fatigue. Thermoregulation - act of regulating internal temperature: mechanism that prevents an excessive rise in core temperature. Exercise and fluid regulation: exercise imposes an added challenge to the thermoregulatory system. 2 types of heat adaptation: heat acclimation - artificial induce heat adaptation, heat acclimatization - warm-weather training camps. Heat adaptation protocols: short term heat adaption (<7 heat exposures (stha), medium-term ha (8-14 heat exposures (mrha)) Typically how long it takes to adapt: long-term ha (15+ heat exposures (ltha)) Time = hours of exposure (can be passive or active) We need to introduce stimulus that is greater than what you have been experiencing.
