Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / 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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Endothelial function
Time Frame: It was evaluated for the control and experimental extremities before exercise.
Endothelial function was evaluated with flow-mediated dilation.
It was evaluated for the control and experimental extremities before exercise.
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.
During exercise
Endothelial function
Time Frame: It was evaluated for the control and experimental extremities 15 minutes after exercise. ( Outcomes were evaluated as acute.)
