We have been investigated the significance of skin temperature in local and locomotive exercise. Present studies were first designed to study the effects of load and muscular contraction velocities to the skin temperature by forearm flexion. Second, influence of skin temperature to maximum grip strength, and its rising tension and duration of sustained contraction were investigated by immersion of forearm in various water temperatures. Third, the effect of training by treadmill running to skin temperature was also studied. All of the skin temperatures in this experiment were recorded by thermistor method from each surface of the body. The obtained results are as follows : 1) In local exercise : forearm flexion, the increase of skin temperature on m. biceps brachii immediately after the exercise was facilitated by flexion velocity, but inhibited by load (30% load of maximum strength). 2) Rate of rising tension curves of maximum grip strength and its duration were bigger in the same water temperature as the skin by immersion of forearm in various bath water temperature. 3) Training effect of skin temperature by treadmill running showed a tendency to inhibit the transient decrease of skin temperature appeared immediately after the beginning of running.
