| Abstract |
The purpose of the present investigation was to find out if women with high levels of body fat (30±3%) had a different reaction to being immersed in cold water from those having low levels of body fat (20.5±2%). The thermal and metabolic responses of six women in each category were monitored during acute exposure to 17°C water for 120min. The following variables were measured: rectal temperature, mean skin temperature, oxygen consumption and tissue insulation. Unexpectedly, only one of the variables demonstrated a main effect for fat. Rectal temperature demonstrated a significant group by time interaction. However, mean skin temperature demonstrated a main effect for time. While oxygen consumption demonstrated an increase across time, these changes were non-significant. It appears that the high-fat (HF) group demonstrated a similar thermal and metabolic response as their low-fat (LF) counterparts. However, the LF groups maintained a lower rectal temperature as compared with the HF subjects. Perhaps leaner subjects or colder water temperatures would elucidate the value of body fat in females, and demonstrate a differential response with respect to females varying in percent body fat. |
