The purpose of this study was to examine the caloric intake and energy output of swimmers and runner during normal daily activities and training. Daily and energy expenditure of twenty college varsity swimmers and runners were measured. Four groups of subjects were categorized as male runners, female runners, male swimmers, and female swimmers with five subjects in each group. An additional twenty runners and swimmers recorded only dietary intake. Despite a large difference in body weight and body fat, the mean daily caloric intake was similar for the two groups (male swimmers: 3377 Kcal/d-1, male runners: 3463 Kcal/d-1, female swimmers: 2491 Kcal/d-1, female runners: 2037 Kcal/d-1). Comparison of data normalized for body weight showed that male runners were more active than swimmers. Male runners burned more calories (53.3 Kcal/kg. d-1) in a twenty four hour period than swimmers (47.6 Kcal/kg.d-1). In the case of the females, the trend was reversed. Female swimmers expended more calories (45 Kcal/kg .d-1) than runners (38.9 Kcal/kg.d-1) despite a lower food intake. Consequently, caloric intake and life style does not seem to explain body fat difference between runners and swimmers. The data in this study suggest that the greater body fat found in swimmers may be related to a physiological adaptation induced by swim training.
