Adenosine deaminase activity was shown to decrease in each skeletal muscle type (the slow-twitch oxydative, fast-twitch oxydative - glycolytic and fast-twitch glycolytic) at the beginning of exercise of moderate intensity and to return to the control when exercise was continued till exhaustion. 5 min occlusion of the femoral artery had no effect on the enzyme activity in either muscle. The reduction of the enzyme activity at the onset of exercise could result in reduction of adenosine breakdown and thus contribute to vasodilation at this stage of increased contractile activity of the muscles.
