Treatment and study plan

Blood Flow Restriction

Other

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.

Other names: Nordic Hamstring Exercise

Primary outcomes

  1. Endothelial function

    Time frame: It was evaluated for the control and experimental extremities before exercise.

    Endothelial function was evaluated with flow-mediated dilation.

  2. Surface EMG

    Time frame: 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

    Time frame: 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.
