Abstract
The effect of local isometric exercise on hand and forearm blood flow was studied. With maximum muscular exercise performed by both males and females, a decrease in hand and forearm blood flow was due to vasoconstriction caused by the mechanical pressure of working muscles. With 75 and 50% loads, marked hyperemia was observed in the main and microcirculatory vessels in the hand and forearm, which was rather long-lasting in the hand because of the difficulty of the forearm venous outflow. The minimum loads affected mainly the microcirculation, and no significant hemodynamic changes in main vessels were observed. The exercise performed at 50% of maximum muscular force was taken as an optimum load in kinesotherapeutic programs.
