Arms and Interventions

Arm Intervention/Treatment
Experimental: blood flow restriction + Nordic hamstring exercise

Other: Blood Flow Restriction
After randomization, a cuff was placed proximal to one lower extremity. Blood flow was restricted from 60% of the arterial occlusion pressure. The other extremity was determined as the control group. 3x5 nordic hamstring exercises were performed. Surface emg was measured for hamstring muscles during exercise.

    Outcome Measures

    Primary Outcome Measures

    1. Endothelial function [It was evaluated for the control and experimental extremities before exercise.]

      Endothelial function was evaluated with flow-mediated dilation.

    2. Surface EMG [During exercise]

      It was evaluated for the biceps femoris and semitendinosus muscles of the control and experimental extremities during Nordic hamstring exercise.

    3. Endothelial function [It was evaluated for the control and experimental extremities 15 minutes after exercise. ( Outcomes were evaluated as acute.)]

      Endothelial function was evaluated with flow-mediated dilation.
