摘要: 目的:探讨不同压力血流限制(BFR)结合低强度抗阻训练对男性大学生下肢肌肉及心肺功能影响。方法:27名健康男性大学生随机分为对照组(C组)、低压组(L组)、高压组(H组),每组9人,受试者大腿近端放置可充气非弹性袖带后分别进行无压力、120 mmHg、180 mmHg,进行20%1次重复最大力量(1RM)强度的负重半蹲训练,比较每周3次,共12周训练前后及各组间股直肌、股中肌肌肉厚度(MTH)、相对伸膝峰值力矩(rM)、峰值功率(P)、相对最大摄氧量(rVO2max)、每搏输出量(SV)、心输出量(CO)、射血分数(EF)等指标的变化。结果:与训练前比较,12周训练后L组和H组股直肌MTH、股中肌MTH、rM、rVO2max、SV、EF均显著提高(P<0.05,P<0.01),且显著高于训练后C组(P<0.05,P<0.01),而L组与H组之间无显著性差异。结论:12周120 mmHg或180 mmHg压力下20%1RM强度BFR训练均可有效提高男性大学生股四头肌肌肉厚度及力量并显著提高心肺功能。

Abstract: Objective: The study compared the effects of low intensity resistance training with blood flow restriction (BFR) with different occlusion pressure on lower limb muscle and cardiopulmonary function. Methods: Twenty-seven college students were randomly divided into three groups by different occlusion pressure: 0 mmHg (group C), 120 mmHg (group L) and 180 mmHg (group H). Before and after training (3 times a week for 12 weeks) with an inflatable cuff (20% 1RM, half squat), the muscle thickness(MTH)of rectus femoris and medius femoris, relative peak knee extensor moment(rM), peak power(P), relative maximal oxygen uptake(rVO2max), stroke volume(SV), cardiac output(CO), ejection fraction(EF) and other indicators were measured for all subjects. Results: When compared with pre-training, and rectus femoris, the MTH of medius femoris, rM, rVO2max, SV, CO and EF were significantly increased in group L and group H after 12 weeks training(P<0.05, P<0.01), as well as compared with group C after training(P<0.05, P<0.01). There was no significant difference between group L and group H after training. Conclusion: BFR training protocols under 120 mmHg or 180 mmHg pressure were effective in improving muscle and cardiopulmonary function.

Key words: different occlusion pressure, blood flow restriction training, muscle function, cardiopulmonary function
