摘要：Paz GA, Maia MF, Lima VP, Oliveira CG, Bezerra E, Simão R, Miranda H. Maximal Exercise Performance and Electromyography Responses after Antagonist Neuromuscular Proprioceptive Facilitation: A Pilot Study. JEPonline 2012;15(6):60-67. Antagonist stretching may promote agonist performance-enhancement. Thus, the purpose of this study was to investigate the acute effects of antagonist proprioceptive neuromuscular facilitation (PNF) on agonist activation and strength performance. Ten men (22.4 ± 0.9 yrs, 74.7 ± 7.7 kg, 172 ± 0.05 cm) participated as subjects in this study. All subjects had previous resistance training experience. Initially, the 10 RM test and retest were applied for wide grip seated row exercise (SR). In the traditional protocol (TP), the subjects performed a set on SR exercise with 10 RM loads. For antagonist PNF stretching (PNFA) the subjects performed 40 sec of PNF on shoulders adductors followed by a set of SR. EMG data of the latissimus dorsi, pectoralis major (clavicular fibers), biceps brachii and triceps brachii (lateral head) were registered. The paired t-test was used to statistically analyze the data, using an alpha level of P.
