The effect of temperature on resting metabolic rate
The body uses various methods to regulate core body temperature in both cold and hot environmental temperatures which could potentially affect an individual's VO2 consumption. The purpose in the current investigation was to determine if resting metabolic rate (RMR) changes as body temperature changes. Eight subjects, 4 males and 4 females, 20 ± 1.3 years from the general population of Warrensburg, Missouri, volunteered for this study. The subjects were immersed chest deep in hot water at 41.5 ± .48°C and cold water at 11.4 ± 1.7°C for 20 minutes, core temperature and VO2 consumption was recorded each minute. No significant relationship was found between core temperature and VO2 consumption during the cold water immersion r(6)=.318, p>.05 or the hot water immersion r(6)=.497, p>.05. Based on data collected, resting metabolism is not related to changes in core temperature when subjects are immersed in hot or cold water.
