Influence of Incremental Work Tasks on Thermoregulation in Air and during Immersion in 18, 26 and 33C Water: Special Reference to Moderately Fat Subjects.

Abstract

The present investigation has studied thermoregulation in a group of moderately fat (18-22% body fat) college-age men during water immersion, and the interrelationships between temperature (cold stress), work intensity (metabolic stress), and body composition (% body fat). The metabolic, thermal, and cardiovascular adjustments were determined at rest and during graded submaximal exercise in air and during water immersion at 18, 26, and 33C. Based on the present observations, the following conclusions are warranted: Fat subjects demonstrated slightly higher VO2 and HR values in 33C water than in air. However, in cool (26 C) or cold (18 C) water, fat subjects did not demonstrate any significant change in VO2 or HR during rest or submaximum exercise.
