两种肌肉调理方法对新学员5km越野后肌疲劳干预效果的比较

 目的 观察本体感觉神经肌肉促进法(proprioceptive neuromuscular facilitation,PNF)与心理肌肉放松法对新学员5 km越野训练肌疲劳的影响,以得出最佳运动后疲劳的恢复方式.方法 选择南京某院校2006-09入学的144名新学员作为研究对象,随机分为A组(PNF干预组)、B组(心理肌肉放松干预组)和C组(对照组),在训练前、训练后第3天、第5天分别评定肌疲劳度并行相关血液生化指标检查.结果 PNF干预组训练后第3天、第5天的肌疲劳程度及血液生化指标增幅较心理肌肉放松干预组及对照组低,心理肌肉放松干预组训练后第3天、第5天的肌疲劳程度及血液生化指标增幅仅较对照组低.3组新学员肌疲劳变化程度差异和相关血液生化指标平均增幅差异均有统计学意义(P<0.05),其中PNF干预组<心理肌肉放松干预组<对照组.结论 PNF法与心理肌肉放松训练法均能有效降低参训人员运动后疲劳,其中PNF法作用更显著.

The interactive comparison of two kinds of muscle adjustment methods on muscle fatigue among new students experiencing 5 km cross-country race training

Objective To study the effect of proprioceptive neuromuscular facilitation and mental muscular alleviation on mus- cle fatigue among new students experiencing 5 km cross - country race military training in order to find the ideal means of recovery after sport fatigue.Methods 144 new students at a Nanjing military academy were selected and randomized into group A(PNF interventions after training),group B(mental muscular alleviation intervention after training) and group C(without interventions),respectively.The degree of muscle fatigue and blood biochemistry parameters were precisely observed before and on Day 3,5 after 5 km race military training.Results The degree of muscle fatigue and increase in blood biochemistry parameters in group A(PNF intervention after train- ing) were lower than those in group B(mental muscular alleviation intervention after training) and group C(without interventions) on Day 3,5 after 5 km military training.The degree of muscle fatigue and the increase in blood biochemistry parameters in group B(mental muscular alleviation intervention after training) were only lower than those in group C(without Interventions) on Day 3,5 after 5 km af- ter 5 km military training.Significant difference in the degree of muscle fatigue and average increase of blood biochemistry parameters were observed on Day 3,5 after 5 km military training between the three groups(P <0.05).The biggest increase occurred in group C, followed by group B and group A.Conclusions Both PNF and mental muscular alleviation are effective methods for reducing muscle fatigue after sports.PNF is better.
