摘要

The influence of heat acclimation on skeletal muscle metabolism during submaximal exercise was studied in 13 healthy men. The subjects performed 30 min of cycle exercise (70% of individual maximal O2 uptake) in a cool (21 C, 30% relative humidity (rh) and a hot (49 C, 20% rh) environment before and again after they were heat acclimated. Aerobic metabolic rate was lower (0.1 1/min; P < 0,01) during exercise in the heat compared with the cool both before and after heat acclimation. Muscle and plasma lactate accumulation with exercise was greater (P<0.01) in the hot relative to the cool environment both before and after acclimation. Acclimation lowered (P < 0.01) aerobic metabolic rate as well as muscle and plasma lactate accumulation in both environments. The amount of muscle glycogen utilized during exercise in the hot environment did not differ from that in the cool either before or after acclimation. These findings indicate that 1) accumulation of muscle lactate is increased and aerobic metabolic rate is decreased during exercise in the heat before and after heat acclimation; 2) increased muscle glycogen utilization does not account for the increased muscle lactate accumulation during exercise under extreme heat stress; and 3) heat acclimation lowers the aerobic metabolic rate and muscle and blood lactate accumulation during exercise in a cool as well as a hot environment. Keywords: Environmental stress; Hyperthermia.
