Effect of Static Stretching and Neuromuscular Facilitation Stretching on Hamstring Flexibility of Subjunior Students

Abstract

The benefits of flexibility training for performance enhancement and injury prevention have been extensively documented. The scientific evidence supporting these assertions is still in its early stages because of the myriad of factors that might influence injury and performance. Nevertheless, flexibility exercises remain a staple of most structured exercise regimens.

Exercising in a variety of methods might help you become more flexible and looser. Which stretching method is better is still up for discussion. Some of the most common ways to stretch muscles are static stretching, ballistic stretching, and PNF stretching, which stands for proprioceptive neuromuscular facilitation. The researchers set out to determine how different types of stretching static and proprioceptive neuromuscular facilitation (PNF) impacted hamstring flexibility.

90 randomly named boys aged 14 to 16 studying in classes 8 and 9 of Mary Nilayam English The research was conducted at Pongummood Medium School in Thiruvananthapuram. In this study, participants were required to complete the Sit-and-Reach test to the farthest point using both hands. This test was designed to measure how flexible the hamstring muscles are. The participants were asked to sit and grasp for an object. Additionally, their test scores were used to split them into three equal groups. The experimental groups, which consisted of 30 students each, were split into two groups and given different stretching methods: static stretching and PNF stretching. Thirty people made comprised the Control group, the third and final group. Over the course of six weeks, each experimental group participated in a structured training program that met three times a week for forty minutes each session.

Statistical significance was determined by comparing the pre- and post-test scores of the control and experimental groups using a t-test. The F-F-ratio was used to analyse data pertaining to the post-test scores of the control group and the experimental group on hamstring flexibility. Based on the data obtained and the constraints of the study, it was determined that a 6-week flexibility training program improved hamstring muscle flexibility. When comparing the two methods of increasing flexibility in schoolchildren's hamstring muscles, the PNF stretching approach seems to be better.
