Introduction[edit | edit source]

Physiology[edit | edit source]

Effects[edit | edit source]

Heat gain of the body, and thus effects of exercising in the heat, would occur when environmental temperatures are greater than skin temperatures. [1]

Exercise in the heat, for 10-14 days, at

  • low-intensity, <50% VO2 max, and a long duration, 60-100 mins, or
  • moderate to high intensity, 75% VO2 max, and a short duration, 30-35 mins,

results in, [1]

  • increased plasma volume, blood flow, perspiration
  • increased VO2 max, maximal cardiac output, power output at the lactate threshold
  • reduces body temperature and heart rate responses with submaximal exercise
  • reduces salt loss on sweat and the occurrence of sodium depletion
  • increases aerobic fitness capacity and performance


This is the process of acclimation and helps with safeguarding against heat illnesses.

Benefits[edit | edit source]

Risks of prolonged exposure to the Heat[edit | edit source]

As mentioned on the Heat Illness in Sports page, prolonged sporting activities in the heat can cause adverse reactions, which could even result in death. It is important to recognize signs and symptoms, and prevent the onset of these illnesses rather than treat or manage the conditions. [1]
