Comparing the Effects of Various PNF Stretching in Improving the Hamstrings Flexibility in Athletes

Abstract

1In sports, flexibility is the major component in preventing any injury. Hamstrings and calf muscles are commonly injured in athletic events. Flexibility can be increased by doing active and passive warm-ups such as stretching, hot showers, massages, various heating modalities. There are various techniques of stretching such as Static stretching, Ballistic stretching, and PNF stretching. of the various stretching techniques PNF technique is effective in increasing the flexibility of muscle tendon unit. Hold-Relax, Agonist contraction, Hold-Relax with Agonist contraction are the PNF techniques which are very much effective in increasing the Range of Motion of the muscle by increasing the extensibility. This study deals with comparing the effectiveness of various PNF stretching like, Hold-Relax, Agonist contraction and Hold-Relax with agonist contraction in increasing the flexibility of hamstring muscle in athletes.
