The subjects were trained by hand-ergometer with a work load of 1/3 of maximum grip strength of their nondominant (left) hands 5 days/week for 6 weeks. Muscular endurance tests were performed with each forearm on the same hand-ergometer prior to muscle endurance training and during 6 week training and detraining periods. In the training and testing, therefore, the subjects were asked to lift the weight 1 cm against gravity at the rate of 60 rpm controlled by metronome until exhaustion. It was found that forearm circumference, grip strength and resting blood flow of both trained and untrained hands did not change due to the muscle endurance training. However, the number of contractions and forearm peak blood flow after hyperemia and exhaustive exercise were significantly increased not only in the trained left hands but also in the untrained right hands. In addition, the improvements obtained by the training were attenuated in the trained extremity during detraining. In spite of reduction of vasodilatory capacity in the untrained hands during detraining. endurance performance did not decrease greatly as compared with vasodilatory capacity. From these results, it was suggested that cross transfer effect. with respect to muscle endurance performance observed in the contralateral limb during detraining, could be maintained considerably due to the vasodilatory capacity or central neurological factors or both.}, pages = {59--73}, title = {トレーニング中止が前腕血流量および筋持久力に及ぼす影響 : 交叉性トレーニング効果との関係}, volume = {18}, year = {1995} }
