INTERMITTENT VERSUS CONTINUOUS HEAT EXPOSURE
Gill, N., & Sleivert, G. (1997). Is intermittent heat exposure as effective as daily heat exposure for heat acclimation? Medicine and Science in Sports and Exercise, 29(5), Supplement abstract 563.
The effectiveness of a daily acclimation protocol compared to an intermittent acclimation protocol was investigated in two groups of competitive rowers (N = 7) under two conditions: 10 consecutive days of acclimation to heat, or intermittent acclimation of 10 days spread across three weeks.
Rates of acclimation were significantly faster and greater changes in variables (e.g., perceived exertion, heart rate, rectal temperature) recorded in the continuous exposure condition.
Implication. Continuous exposure to heat produces the fastest and greatest amount of heat acclimation.
