Heat acclimation is frequently added to training regimens. Adaptations to heat that have the potential to improve athletic performance as a consequence of heat adaptations include:(Select all that apply, even if only one applies)Group of answer choicesIncreased cardiac outputIncreased skin blood flowLower sweat thresholdIncreased thermogenic capacityPlasma expansionLower resting heart rate

The key adaptation to heat acclimatisation is:Group of answer choicescardiac hypertrophyexpanded blood volumereduced sweat sensitivity

Poor heat acclimatization and fitness levels can greatly contribute to an athlete’s heat tolerance and heat illness risk. True False

The primary mechanism for heat loss during exercise in a warm (~30C) environment is:Group of answer choicesconvectionevaporation of sweatradiation

The hierarchy of priority for blood flow during prolonged exercise in the heat is:Group of answer choicesbrain > muscle > skinskin > brain > musclemuscle > brain > skin

When environmental air temperature exceeds skin temperature and relative humidity increases during exercise, heat is lost by the body through convection and/or radiation. sweat is evaporated more easily. the sweat rate volume increases. heat is gained by the body through conduction.
