Brief Summary

This study was conducted to compare the effects of the static and Mulligan bent leg raise (BLR) techniques applied to address hamstring tightness on jumping performance. Participants with hamstring tightness participated in the study and were randomized into two groups. Group 1 (Classic Stretching Group) underwent a 30-second hamstring stretching protocol consisting of 5 repetitions. Participants in Group 2 underwent the BLR technique. Participants' active knee extension, vertical jump, and single-leg horizontal jump were measured before and after the study.

Interventions

Mulligan Bent Leg Raise (BLR) Technique OTHER

The Mulligan bent leg raise technique involves isometric contraction followed by stretches applied to the hamstring muscle in specific directions. The aim is to increase hamstring flexibility and active knee extension range of motion. The participant lay supine on an elevated bed, while the physiotherapist sat lateral to the leg to be stretched, placing the popliteal fossa of the participant's knee on their shoulder. The hip and knee of the leg to be stretched were flexed to 90°. Distraction was applied to the lower end of the femur, and the participant was asked to push the physiotherapist's shoulder with their leg and then relax. At this point of relaxation, the physiotherapist pushed the flexed knee as far forward as possible in the direction of hip flexion within a painless range. This position was held for 5 seconds at the end of the movement. Then, the neutral position was returned, and the procedure was repeated three times

BLR

Static Stretching OTHER

Participants lay supine on a stretcher with their backs straight. With the knee fully extended, the physical therapist placed the participant's leg on their shoulder and supported the ankle
