ABSTRACT
The effects of 3 week training program (6 day a week) on the forearm blood flow before, during and after rhythmic hand-grip contraction on nineteen subjects was studied. The rhythmic hand-grip contraction was performed on a hand-ergometer with a load of 30% of maximum grip strength (M. G. S.) of each subjects, at a rate of 60 beats/min as time with metronome. The forearm blood flow before, during and after rhythmic hand-grip exercise was determined with a mercury-in-rubber strain-gauge venous occlusion plethysmography.<BR>The following results were obtained;<BR>1) The maximum grip strength did not change significantly before and after training.<BR>2) The number of contraction (muscular endurance) up to exhaustion increased from 166.0 to 284.9 at the end of training (p<0.001) .<BR>3) The resting forearm blood flow did not change significantly during straining period.<BR>4) The peak blood flow during exercise (p<0.01), the blood flow final minute of exercise (p<0.05) and the blood flow immediately after exercise (p<0.05) in the forearm increased significantly after training.<BR>5) From these results, it is concluded that the muscular endurance training with a load of 30% M. G. S, increase the muscular endurance and blood flow during rhythmic hand-grip exercise.
