Our laboratory has been pursuing studies involving the physiological action of static stretching on sportsman. The following results have been obtained. (1) Stretching exercises of 27 items were recorded in 6 volunteers (members of the university Judo club). The mean heart rate at rest was 67 beats/min; 82 to 84 in steady-state and 71 at five minutes after treatment. Amount of oxygen consumption (Vo_2) at rest and after exercise were 237 ml/min and 255 respectively, while in stretching it amounted to 610 ml/min (at 15 minutes). These results show the intensity of the exercise is similar to that of walking. (2) In the ankle dorsiflex stretching in the prone position (7 healthy athletes and 7 sportsinjured), dynamic variance was shown in the contact thermogram (skin temperature) of the calf; but not shown in the other. (3) From another work-load experiments (15 subjects) consisted of stretching, ballistic exercise, and control, it appeared obvious that stretching exercises involve the muscle action with slight high amplitude voltage (7. 7mV in the EMG histogram), and the action with less loaded motion than ballistic exercises (9.2mV). (4) The maximal muscle strength due to flexion in the elbow joint was measured on two occasions: one measurement (6 cases) was taken after barbell curl exercise and strengthening, and the others (4 cases) after b-c exercise and resting. Muscle strength of the group with stretch cooling-down was wellpreserved than that of with rest cooling-down. (5) Eight volunteers (members of the university soccer club) were undergone the low frequency electric therapy for twenty minutes under different conditions. After the treatment was over, the distance between the finger tip and the floor in standing hamstring stretch was magnified by 1.6-5.3 cm. From these observations, it would appear that static stretching has the nature of being a slight work-loading, enlarging the peripheral circulation, preserving the muscle temperature, and promoting flexibility of the joint. The two works (static stretching and ballistic exercise) are quite different in character. Active static stretching forms a "part" of warming-up and/or cooling-down menu but is not inclusive for athletes.
