An Analysis of the Use of Proprioceptive Neuromuscular Facilitated Stretching Methods on Explosive Strength Performance in Wrestling

Abstract

This paper is trying to analyze how proprioceptive neuromuscular facilitation (PNF) methods can improve muscular diastolic capacity. The research aims to identify the effect of using one of PNF method (Hold – Relax with agonist contraction) on explosive strength for wrestlers, and the Efficiency of the Reverse Body Lift skill performance for 16 volunteered healthy male wrestlers. Subjects classified into two Groups: Experimental and Control Group. Results reveal that post-measurement of 3 times of Bridge up test (Sec) significantly decreased (7.17±0.33, 6.4±0.37) for post and pre-measurements respectively. Flexible of spine (cm) significantly decreased (22.3±0.93, 20.57±1.01) for post and pre-measurements respectively, with improvement percentage of (7.09%) .Vertical distance (cm) significantly increased (18.61±0.90, 20.33±1.02) for pre and post-measurements respectively, with improvement percentage of (8.46%). Explosive strength (Sec) significantly decreased (13.61±1.41, 11.7±0.71) for post and pre-measurements respectively, with improvement percentage of (14.03%). Reverse Body Lift skill (cm) significantly increased (6.03 ± 0.57, 7.76 ± 0.97) for pre and post-measurements respectively, with improvement percentage of (22.29%), the most important conclusion was that applying training program that contains PNF exercises lead to an improvement of all physical variables, and led to the significant improvement in performance.
