摘要
研究目的:本文通过探讨不同动作节奏(TUT)的力量训练对上肢肌肉最大力量和围度的影响,探寻最佳动作时长的时间比例。研究方法:采用实验法对16名排球运动员进行不同动作节奏的卧推训练。实验组为4-2-1节奏训练组(n=8),对照组为4-0-1节奏训练组(n=8),通过8周实验干预对比训练前后卧推最大力量、胸部和上臂围度的变化。结果:8周实验干预后,4-2-1与4-0-1动作节奏训练组卧推最大力量和上肢肌肉围度均有显著性提高,4-2-1动作节奏训练对卧推最大力量和肌肉围度的影响明显优于4-0-1动作节奏训练。结论:以85%1RM负荷重量进行动作节奏训练,两组动作节奏训练通过延长动作时长能有效提高肌力和增加肌肉围度,而4-2-1动作节奏训练较4-0-1动作节奏训练效果更明显。
OBJECTIVE:The purpose of this paper is to study the influence of Time Under Tension(TUT)strength training on the maximum strength and circumference of upper limb muscles,and to explore the time proportion of optimal movement duration.METHODS:16 volleyball players received training of bench press at TUT.The experimental group was 4-2-1 tempo training group(n=8),and the control group was 4-0-1 tempo training group(n=8).The changes of maximum bench press strength,chest and upper arm circumference were compared before and after 8 weeks of experiments.RESULTS:After the 8-week intervention,the maximum strength of bench press and the muscle circumference of upper limbs in both the 4-2-1 tempo and the 4-0-1 tempo training groups significantly increased.The effect of 4-2-1 tempo training on maximum strength of a bench press and muscle circumference was remarkably higher than that of 4-0-1 tempo training.CONCLUSIONS:TUT training with 85%1 RM load weight can effectively improve muscle strength and muscle circumference in the two groups by extending the duration of movement,and 4-2-1 tempo training has more obvious effect than 4-0-1 tempo training.
