Effect of Dynamic Stretching versus Proprioceptive Neuromuscular Facilitation Stretching of Antagonist Muscle on Knee Extensor Torque and Dynamic Balance in Young Male Collegiate

Abstract

Introduction: Many athletes perform stretching exercises as part of a warm-up prior to physical activity in order to prevent injuries and enhance their performance by an increase in flexibility. The significance of this study was that it may provide information about the better stretching method between dynamic and PNF stretching immediately before the sports events which may help to enhance the strength of knee extensor, thereby helping in improving performance and injury prevention.Method: An experimental design was used in the study. 51 subjects were randomly divided and statistically analysed for results. Group 1 had to under go dynamic stretching, Group 2 had to undergo PNF stretching for a period of four, and Group 3 (control group) did not undergo any kind of stretching. Results: It was observed that there was no significant difference in peak torque and average torque at 60⁰/s and 180⁰/s and SEBT scores after 4 weeks of dynamic vs PNF stretching. No significant difference was found in dynamic balance after 4 weeks of dynamic vs PNF stretching. Conclusion: We may infer that dynamic stretching and proprioceptive neuromuscular facilitation stretching of antagonist muscle have the same effect on knee extensor torque and dynamic balance in young collegiate males.
