摘要：The purpose of this study was to determine the effects of PNF stretching combined with resistance training on performance during an 8-week training protocol in non-athlete male students. Twenty healthy non-athlete males (age 21.3 ± 1.3 years, height 174.7 ± 2.9 cm, weight 71.1 ± 2.4 kg) college students were randomly divided into a resistance training (RT) group (n=10), or resistance training combined with Proprioceptive neuromuscular facilitation (PNF) stretching (RT + PNF) group (n=10). The resistance training program was performed 3 days (Sunday, Tuesday and Thursday) each week for 8 weeks. The resistance training consisted of 3 lift (triceps pushdown, bench press and lateral pull down), 3 sets of 8 repetitions, and the initial weight was 80% of the pre-1RM. The 8 weeks stretching program consisted of 15 different PNF stretches designed to stretch all of the major upper-extremity muscle groups (pectoralis major, triceps, biceps, teres minor & major, deltoidus). Subjects were tested for performance before and after the 8-week period. The results of this study indicated significantly (P< 0.05) improvements in strength, muscle volume and flexibility from Post test occurred for both RT and RT + PNF groups when compared to Pre test. There were also no significant differences (P> 0.05) between groups. However, findings showed the RT + PNF group had slightly more improvements in strength, muscle volume and flexibility when compared to RT group. It can therefore, be concluded that within 8 weeks PNF stretching combined with resistance training was found can not necessarily be effective on muscle volume, strength and flexibility more than RT only
