Abstract
The circulatory and metabolic changes during prolonged exercise (60 min) were studied in a group of eight healthy pubertal girls. The girls worked on the treadmill and on the bicycle ergometer at 43 -47 of the respective VO2max, i.e., 1.2 W|kg body weight (BW) on the bicycle and 4 km|h with 5 inclinationon the treadmill. The heart rate increase during prolonged exercise was the same in both types of exercise. The blood lactate increase was negligible in the initial phase with subsequent removal from the blood during extended exercise. The increasing free glycerol concentration in blood indicates similar fat share in energy release in children and adults. No biologic handi-cap could be found for prolonged exercise in pubertal girls. Verf.-Referat
