The Effect Of Proprioceptive Neuromuscular Facilitation With The Hold-Relax Method On Flexibility Hamstring Muscles Of Basketball Club Mansa Athletes

Abstract

This study examines the issue of suboptimal hamstring muscle flexibility in Mansa Basketball Club athletes, which may limit range of motion, reduce performance, and increase the risk of injury. The objective is to determine the effect of Proprioceptive Neuromuscular Facilitation (PNF) using the Hold-Relax method on hamstring muscle flexibility in these athletes, as well as to measure the extent of improvement. This quantitative study employed a pre-experimental design with a one-group pretest-posttest design, involving 12 Club Mansa athletes as both the population and sample. Data collection was conducted through the V-sit test administered before (pretest) and after (posttest) the 7-day consecutive PNF Hold-Relax intervention. Data analysis included descriptive statistics, Shapiro-Wilk normality test (since the sample size was ≤ 50), and paired sample T-test hypothesis testing with a significance level of p<0.05. The results showed a significant increase in flexibility. The pretest average was 5,33, which increased to 11,75 in the posttest. The hypothesis test yielded one-sided and two-sided significance values <0.001, with a t-value of -6.124 and 11 degrees of freedom. This indicates that H0 is rejected and Ha is accepted, confirming that PNF using the Hold-Relax method significantly improves hamstring muscle flexibility in Club Mansa basketball athletes. In conclusion, the PNF Hold-Relax intervention was proven effective in improving hamstring muscle flexibility in Club Mansa basketball athletes
