摘要: 目的:采用间歇时间再分配训练法与传统训练法进行离心训练,对比训练中的动力学表现,探讨间歇时间再分配训练在离心运动中的作用效果和生理机制。方法:11名健康男性受试者在非连续的两周内进行不同训练安排的离心训练。传统组为每组10次重复,共4组,组间间歇为95 s。间歇时间再分配组为每组2次重复,共20组,组间间歇为15 s。以等速肌力测试仪采集的力矩和总做功作为动力学表现评价指标,利用近红外光谱分析仪采集局部氧含量数据。以RPE评价主观疲劳程度。利用Excel和GraphpadPrism 5进行数据整理,利用SPSS和JASP对实验数据进行统计学分析。结果:与传统组相比,间歇时间再分配分组法对训练中的肌肉发力能力具有保持作用(P<0.05),但总做功未见明显组间差异(P>0.05);可致组织氧饱和度显著下降(P<0.05),但总血红蛋白浓度和RPE无显著组间差异(P>0.05)。结论:间歇时间再分配训练可提高大强度离心训练中的动力学表现和运动负荷,并增加肌肉的耗氧量,提高训练刺激。训练中的疲劳水平与传统训练相近。

Abstract: Objective: To investigate the effects and physiology mechanism of rest-redistribution and traditional sets by measuring kinetic performance during eccentric training. Method: 11 healthy male volunteers perfumed rest-redistribution training and traditional training on two inconsecutive weeks' Monday. For each protocol, participants performed 40 repetitions with 285 s of total rest, respectively, traditional sets had 4 sets of ten repetitions with 95 s inter-set rest and rest-redistribution sets had 20 sets of 2 repetitions with 15 s inter-set rest. Peak torque and total work were measured to evaluate kinetic performance, meanwhile tissue oximetry was assessed throughout each protocol to detect local circulation and oxygen consumption. RPE was inquired during and after the training. Excel and Graphpad Prism 5 were used to unscrambling data after experiment followed by data analysis with SPSS and JASP. Result: Rest-redistribution sets maintained force development ability during eccentric training (P<0.05) with significantly decline of tissue saturation (P<0.05), whereas no significant difference in total work (P>0.05), total hemoglobin concentration (P>0.05) or RPE (P>0.05) compare to traditional sets. Conclusion: Rest-redistribution contributed to maintenance of kinetic performance during high intensity eccentric training and increase of exercise load, oxygen consumption and training stimulation.

Key words: rest-redistribution sets, cluster sets, eccentric training, sports performance, fatigue
