【摘要】：目的:分析低氧环境下的训练对肌肉爆发力参数的影响。方法:随机选取某市某高校志愿者30名,将其随机分为低氧运动组和常氧运动组,低氧训练组的15位受试者在模拟青海地区海拔环境下进行训练。常氧训练组受试者进行常氧测试。两组受试者均进行相同强度的训练,对最大摄氧量、低氧通气速率、肌肉收缩产生某个运动关节屈伸扭转力矩、对抗肌比、相对平均功率等指标进行测试。结果:低氧训练组受试者最大摄氧量显著低于常氧训练组(P0.05),同时随着运动负荷的逐渐增加,最大摄氧量逐渐降低;两组受试者通气反应速率均随运动负荷的增大而显著增加。低氧训练组和常氧训练组相比,具有非常显著性差异(P0.01)。两组膝关节屈伸肌快速相对峰值力矩实验后均有非常显著性提高;伸肌快速相对峰值力矩增长量低氧训练组非常显著性高于常氧训练组,P0.01;屈肌组间相比,无显著性差异。结论:低氧环境下训练能够有效增强肌肉爆发力,对肌肉爆发力参数有积极的影响。
[Abstract]:Objective: to analyze the effect of hypoxia training on muscle burst parameters. Methods: thirty college volunteers from a certain city were randomly divided into hypoxic exercise group and normoxic exercise group. 15 subjects in hypoxic training group were trained under simulated altitude in Qinghai. Normoxic test was performed in the normoxic training group. The two groups were trained with the same intensity. The indexes of maximal oxygen uptake, hypoxic ventilation rate, torsional torque of a certain movement joint produced by muscle contraction, antagonistic muscle ratio and relative average power were measured. Results: the maximal oxygen uptake in hypoxic training group was significantly lower than that in normoxic training group (P0.05), and the maximal oxygen uptake decreased with the increase of exercise load, and the ventilation response rate of both groups increased significantly with the increase of exercise load. There was significant difference between hypoxia training group and normoxic training group (P0.01). The relative peak torque of knee flexion and extensor muscle of both groups was significantly increased after the experiment, and the increase of relative peak torque of extensor muscle in hypoxic training group was significantly higher than that in normoxic training group (P 0.01), but there was no significant difference between flexor muscle group and flexor muscle group. Conclusion: training in hypoxic environment can effectively enhance muscle explosive force and has a positive effect on muscle detonation parameters.
