Abstract: In several studies estimated energy intake has been found to be low compared with estimated energy expenditure in female athletes. It has therefore been suggested that female athletes may have a depressed basal energy expenditure (BMR). The main purpose of the present study was to explore this possibility by measuring BMR in physically extremely active females. Eight female dancers and 7 controls with low physical activity, all musicians, were studied; the variables measured included body weight, height, skinfold thickness and total body potassium. BMR was measured by indirect calorimetry. In conclusion, the present study lends no support to the idea of a lowered basal metabolic rate in female athletes as an explanation of the general finding of a lower estimated energy intake than energy expenditure in this type of subjects.
