Comparison of Thermal Responses between Rest and Leg Exercise in Water,

Abstract

This study examined both the thermal and metabolic responses of individuals in cool (30 C, n=9) and cold (18 C, n=7; ;20 C, n=2) water. Male volunteers were immersed up the neck for 1 h during both seated rest (R) and leg exercise (LE). In 30 C water, metabolic rate (M) remained unchanged over time during both R (115 W, 60 min) and LE (528 W, 60 min). Mean skin temperature (Tsk) declined (P<0.05) over 1 h during R, while Tsk was unchanged during LE. Data indicated that LE is more effective than R in maintaining core temperatures in both cool and cold water. Also, immersion in cold water elicits differing core temperatures indicating that chest cavity temperature is maintained at a higher level than other core areas.
