Abstract

Amaç: Bu araştırmanın amacı, hamstring kas gerginliği için farklı Propriyoseptif Nöromüsküler Fasilitasyon (PNF) germe tekniklerinin etkinliğini araştırmak ve hamstring esnekliğini geliştirmek için en iyi PNF tekniğini bulmaktır.
Yöntem: Bu yarı deneysel dizaynlı çalışmada 18-25 yaşında, günde >6 saat oturan ve Aktif Diz Ekstansiyon Testi (AKET) >20º olan 30 üniversite öğrencisi elverişlilik örnekleme yöntemiyle seçilmiş ve Grup A, B ve C'ye eşit olarak ayrılmıştır.. Sırasıyla tut-gevşe (HR), agonist kasılma (AC) ve kas-rahatla antagonist kas (CRAC) germe teknikleri verilmiş ve müdahaleler deneklere haftada üç seans, üç hafta süreyle uygulanmıştır.
Sonuçlar: Paired t-testi, HR, AC ve CRAC gruplarının hepsinde ön test ve son test AKET ölçümleri arasında anlamlı farklar olduğunu gösterdi (p<.001). Tek yönlü ANOVA testi, bu tekniklerin etkinlikleri arasında anlamlı bir farklılık olduğunu (F(2,27)=13,069, p<,001); Tukey Post-Hoc testi, etkinin CRAC (-20,033°±2,666°, p<,001) ve AC gruplarında (-17,516°±1,658º, p=,047) HR'den (-15,100°±2,025°) anlamlı olarak daha yüksek olduğunu ortaya koydu.. Ayrıca, CRAC'ın (p=,038) AC'den önemli ölçüde daha fazla etkiye sahip olduğu bulundu.
Tartışma: Bu çalışmada kullanılan PNF germe teknikleri, üniversite öğrencilerinde hamstring esnekliğini geliştirmede etkili olup, en etkili olan CRAC tekniğidir.

A COMPARATIVE ANALYSIS OF VARIOUS PROPRIOCEPTIVE NEUROMUSCULAR FACILITATION (PNF) TECHNIQUES ON MUSCLE FLEXIBILITY AMONG EXTENDED SITTING POSTURE INDIVIDUALS

Abstract

Purpose: The purpose of this research is to compare the effectiveness of different Proprioceptive Neuromuscular Facilitation (PNF) stretching techniques for hamstring muscle tightness, and to find out the best PNF technique for improving hamstring flexibility.
Methods: In this quasi-experimental designed study, 30 university students who were between 18-25 years-old, sitting >6 hours per day, and had a Active Knee Extension Test (AKET) >20º were recruited with convenience sampling and equally allocated into Group A, B and C, non-randomly. Hold-Relax (HR), Agonist Contraction (AC) and Contract-Relax-Antagonist-Contract (CRAC) stretching techniques were given respectively, 3 sessions/week, for three weeks.
Results: Paired t-test showed significant effect of each technique compared between pre-test value and post-test value of AKET measurements of Hold-relax (HR), AC and CRAC groups (p<.001). One-way ANOVA results showed significant difference between the effects of these techniques (F(2,27)=13.069, p<.001). Tukey Post-Hoc test revealed that effect was significantly greater in CRAC (-20.033°±2.666°, p<.001) and AC groups (-17.516°±1.658º, p=.047) than HR (-15.100°±2.025°). Furthermore, CRAC (p=.038) was found to have significantly greater effect than AC.
Conclusion: The PNF stretching techniques used in this study are effective in improving hamstring flexibility among university students. In addition, CRAC technique was found to be the most effective one.
