Muscle Energy Technique and Hamstring Nordic Lower for Hamstring Tightness in Young Athletes

PFS Post-Facilitation Stretch Participants in this arm received the intervention of post-facilitation stretch technique. Post-facilitation stretch involves the application of manual stretching techniques to the targeted muscles after a facilitation phase, which aims to enhance muscle extensibility. The participants underwent a standardized post-facilitation stretch protocol focusing on the hamstring muscles.

Participants in this arm of the study received the intervention of post-isometric relaxation technique. Post-isometric relaxation involves the application of isometric contraction followed by a relaxation phase to promote muscle lengthening and improve flexibility. The participants underwent a standardized post-isometric relaxation protocol targeting the hamstring muscles.

Participants in this arm received the intervention of hamstring Nordic lower exercise. The hamstring Nordic lower exercise is a challenging eccentric exercise that specifically targets the hamstring muscles. Participants performed the exercise under supervision and followed a standardized protocol for the number of repetitions, sets, and rest intervals.
