Several inherent anthropometric and physiological characteristics have been identified as affecting the human response to cold exposure. The purpose of this study was to determine which of these characteristics, singly or in combination, were related to and/or predictive of physiological and perceptual responses to prolonged cold water immersion. Twelve male subjects were evaluated for anthropometric and physiological variables including Body Mass Index (BMI), Body Surface Area (BSA), BSA/mass ratio, % body fat, fat mass (FM), fat free mass (FFM) and relative and absolute V&dot;O2 max which were designated the independent variables. Subjects were immersed in a seated resting posture in 20°C water for 60 minutes. Physiological responses measured included rectal temperature (Tre), forehead skin temperature (Tsk), heart rate (HR), oxygen consumption (V&dot;O2), metabolic heat production (M), minute ventilation (V&dot;E), and time to sustained shivering (T). The perceptual measure was a 10-point scale of perceived thermal sensation (TS). These measures were designated the dependent variables. Pearson Product Moment Correlation Coefficients were performed to identify relationships between the independent and dependent variables. BMI (r = 0.66), BSA/mass ratio (r = -0.64) and FFM (r = 0.61) were found to be significantly correlated (p < 0.05) with Delta Tre. BMI ( r = 0.57) and BSA/mass ratio (r = -0.56) were found to be significantly correlated (p < 0.05) with T. No other dependent variable was significantly correlated with an independent variable. Regression equations were developed to predict Delta Tre and T using the previously mentioned relationships and were found to explain 50% (R2 = .50) and 33% (R2 = .33) of the observed variance, respectively. Thus, inherent anthropometric and physiological characteristics are poor to moderately effective in predicting physiological and perceptual responses during prolonged cold water exposure in males.
