The Effects of Static and Proprioceptive Neuromuscular Facilitation Stretching with Different Duration on Strength and Range of Motion of Wrist in Female Volleyball Players.

Background & Objective: The purpose of this study was to investigate the effects of static and proprioceptive neuromuscular facilitation (PNF) stretching with different durations on handgrip strength and range of motion (ROM) of wrist in Female Volleyball Players. Material &Methods: 10 female volleyball Players with the mean age of 22.1±4.12 participated in the study, voluntarily. Participants performed one of the 30s and 240s static and PNF stretching protocols, and also control condition (120s rest), in a randomly visits with 2 days in between. Before and after the interventions, handgrip strength and range of motion of wrist were measured. Results: Results showed that the ROM significantly increased in the post-test than pretest after all protocols (p<0.05); But, there was not significant difference between the increase between the groups for the ROM. In addition, the handgrip strength significantly decreased in the control, and 240s static and PNF groups (p<0.05), and insignificant increment was observed for the strength of wrist in the 30s static and PNF stretching groups. Conclusion: Performing short-term stretching during warm-up could increase ROM of wrist without negative effect on the handgrip strength in female volleyball players.
