摘　　要：背景:5km越野训练后会使人体出现肌疲劳,常导致各种程度的肌肉酸痛和肌无力等,而神经肌肉促进法可改善关节和肌肉柔韧性。目的:观察感觉神经肌肉促进法对新入学军校学员5km越野训练后肌疲劳的干预作用及最佳干预时机。方法:选择新入学的健康军校男学员,均进5km越野训练。分别在训练前、后针对双下肢、骨盆带肌肉采用本体感觉神经肌肉促进法干预,并设置正常训练组作对照。在训练前,训练后第1,3,5天分别评定其肌疲劳度,并检查相关血液生化指标。结果与结论:训练后第1,3,5天全部对象肌疲劳度和相关血液生化指标肌红蛋白、谷丙转氨酶、谷草转氨酶、乳酸脱氢酶和肌酸磷酸激酶的平均增幅差异均为训练后神经肌肉促进干预组<训练前神经肌肉促进干预组<正常训练组(P<0.05)。结果表明经本体感觉神经肌肉促进法干预可以降低5km越野训练后相关血生化指标的增高,减轻肌损伤,降低肌疲劳。训练结束后当天行本体感觉神经肌肉促进法干预为最佳时机。BACKGROUND：It has been clinically found that often new military students experienced sport injury after 5-km military training.The symptoms mainly include different levels of muscle ache and myoasthenia.Proprioceptive neuromuscular facilitation （PNF） can improve flexibility of joint and muscles.OBJECTIVE：To observe the effect and to explore the optical time that PNF on muscular fatigue among new students experiencing 5-km military training.METHODS：Healthy male new students in a military university were selected and randomized into three groups,who received PNF interventions on muscle around both lower extremities and pelvic girdle prior to or after training,and who with no PNF interventions served as control.The degrees of muscle fatigue and blood biochemistry parameters were precisely observed prior to and at 1,3,5 days and after training,respectively.RESULTS AND CONCLUSION：The significant differences about the degree of muscle fatigue and rate of blood biochemistry parameters （myoglobin,alanine aminotransferase,aspartate aminotransferase,lactate dehydrogenase,creatine kinase） at 1,3 and 5 days after training among the three groups were observed （P0.01）,in which it increased lest in group with PNF interventions beginning after training,next in group with PNF interventions beginning before training,and the most in the control group.Therefore,PNF can reduce the rate of biochemistry parameters and decrease the degree of muscle fatigue on participants after 5-km military training.The result indicates PNF effectively relieve muscle fatigue after intensive physical training and the optical time is to perform PNF right after the training.
