TABLE 6-7 Partition of Energy Expenditure in Three Climates in 1955
conducted in a hot or comfortable environment, the partitioning of energy expenditure was different, that is, less aerobic expenditure and greater anaerobic expenditure in the hot environment (Table 6-9). The results were subsequently confirmed by Dimri et al. (1980). The hypothesized explanation for this partitioning was the diversion of a significant amount of blood from the muscles to the skin for thermoregulation in hot environments. Although
TABLE 6-8 Mean Oxygen Uptake Responses to Exercise Before (B) and After (A) 8 Days of Heat Acclimation
NOTE: Heat acclimation regimen = 3 hours of exercise per day at 41 watts, Tdb = 39.4°C, Twb = 30.3°C, where Tdb = dry-bulb temperature and Twb = wet-bulb temperature.
