年轻柔道运动员在不稳定设备上进行阻力练习时肌肉输出的变化:一个案例研究

BackgroundResistanceexercisesunderunstableconditionshavegainedpopularityamongathletes。该研究的目的是“调查在不稳定条件下的上蹲和下蹲期间肌肉输出的变化”(峰值功率和运动速度)，并将其与稳定条件下的输出进行比较。参与者:��Atotalof 20��,�dividedintotwogroups,�tookpartinthestudy。�Thefirstgroupconsistedof�9�top-lev——elyoungmalejudoists�whilethesecondgroupconsistedof 11��学生。��Alloftheexerciseswereperformedonce�70% ofone-repetitionmaximum�(1 rm)�wasdetermined。结果:分析显示，与稳定条件下的柔道运动员相比，在不稳定条件下下蹲时(“BOSUball”)肌肉输出显著减少。然而，在不稳定的条件下，与平台式相比，在压力下的肌肉输出没有明显的减少(瑞士球)。,��Forthegroupofstudents theanalysisshowedasignificantreductioninmuscularoutputsduring�thebenchpressunderunstableconditionswhencomparedtothestableflatbench。�另外,�forthisgroupthe�muscularoutputsweresignificantlylowerduringsquatsunderunstableincomparisontostableconditions。结论:在减少训练负荷的情况下，在柔道运动员身上进行的杠铃阻力训练不能作为一种有效的训练模式。然而，在不稳定的条件下，训练负荷减少的训练为神经肌肉系统提供了足够的挑战，可以纳入训练计划。
