Study protocols with and without ischemia-reperfusion. a Study protocol with ischemia-reperfusion. b Study protocol without ischemia-reperfusion. a After 10-min bed rest in the supine position, the diameter of the right brachial artery was measured four times, before and after each of three cycles of 5-min inflation (200 mmHg) and 5-min deflation of a blood pressure cuff in the left arm. b. In the control study without ischemia-reperfusion of the left arm, the diameter of the right brachial artery was measured four times, before and after 3 cycles of 10-min bed rest in the supine position.
