Comparative Analysis of Muscular Flexibility among Recreational Racquet Players using Dynamic Oscillatory Stretching and Contract-Relax (PNF) Technique - A Rehabilitative Report

Abstract

Background: Forward lunge is approximately 15% of all movement in racquet games especially badminton. One of the important muscles involved in forward lunge is biceps femoris. It acts as an agonist muscle during the forward lunging for the knee flexion. Increased hamstring tension causes pelvic alternation, which is another important factor in keeping an upright posture. Primitive Objective of this research is to identify the instant effect of rehabilitative Dynamic oscillatory stretching technique and Contract-Relax (PNF) technique on hamstring flexibility in recreational badminton players, and to perform a comparative analysis the acute effect of rehabilitative Dynamic oscillatory stretching and Contract-Relax (PNF) technique on hamstring flexibility in recreational badminton players.

Methods: Quantitative method, quasi-experimental study with a pre-test and post-test design used to estimate the causal influence of the physiotherapeutic intervention. 45 potential participants were volunteered to be involved in this study. Participants were recruited by using the convenience sampling method. Informed consent was acquired from all partakers, and any relevant criteria were mentioned beforehand earlier to the data collection phase.

Results: This study results shown, a significant difference of p-value is 0.18 (p>0.05). Hence, the null hypothesis is accepted as there is no statistically significant difference in effectiveness of DOS group and CR PNF group.

Conclusion: A few studies been conducted targeting particularly recreational badminton players. Hence, this research carried out to develop a framework of different stretching techniques to help us for making a good training program or warm up regime for recreational badminton players to improve their hamstrings elasticity and minimising the risk of injury. The investigation results showed, both techniques would help in improving hamstring flexibility.
