[Changes in body composition during an extreme endurance run].
We measured before, during and after a six-day-run in one athlete body weight, skinfold thickness, circumference of extremities, energy expenditure and nutritional intake. Despite an increased fat and protein intake during the race we found a significantly decrease in adipose subcutaneous tissue of the whole body and muscle mass in the active limbs whereas body weight remained stable. We presume that during running as eccentric exercise subcutaneous adipose tissue and muscle mass will be oxidised.
