The present study was designed to classify adolescents into sprint or endurance types according to physical performance tests. Five hundred sixty-nine normal Japanese boys and girls, ages 13 to 17 years, served as subjects. Performance tests consisted of 50-meter dash, 5-minute run, peak torque at 35 rpm of knee extensor muscles, and some children were tested for isometric endurance time at 50% of maximal voluntary isometric contration of knee extensor muscles. Based on the T-score of peak torque, 22-29% of the boys and girls were classified into fast or slow twitch types. But almost 30% of the classified subjects did not show the expected results. According to the T-scores of three performance tests, three sprint-type boys and seven endurance-type girls were detected. A significant negative correlation was found between peak torque and endurance time among the ten classified subjects.
