概括
这项研究发现,高负荷惯性飞轮没有改善反运动跳跃性能,这表明该协议可能会诱导太多的疲劳,而不是后激活性能提升 (PAPE).
科学领域:

- 运动生理学 运动生理学
背景情况:
- 后激活性能增强 (PAPE) 是一种现象,在此之前的炼可以提高后来的爆炸性性能.
- 惯性飞轮 (IFw) 训练提供了一个独特的阻力特征,可能会影响PAPE效应.
- 了解IFw协议的剂量反应关系对于优化PAPE至关重要.
研究的目的:
- 为了研究高负荷的剂量反应关系,6重复最大惯性飞轮 (IFw) PAPE对反运动跳跃 (CMJ) 协议的性能.
- 为了确定IFw squats对CMJ指标的不同集体量 (1,2,或3组) 的影响.
主要方法:
- 13名受试者接受了会议,以确定背和IFw负载的6重复最大值.
- 试验对象在他们的6重复最大负载下执行了1,2或3组IFw坐.
- 在IFw练习后的多个时间点 (1,3,6,9,12分钟) 用力板分析评估反运动跳跃.
主要成果:
- 对于跳跃高度,接触时间,反应强度指数,峰值力或冲动变量没有显著的主时间或体积效应.
- 对于飞行时间 (P = .006) 和峰值功率 (P = .001) 发现了显著的主时间效应.
- 尽管对一些变量有时间影响,但CMJ整体表现,特别是跳跃高度,并没有改善.
结论:
- 一个高负荷的,最多6次重复的IFw坐协议可能不会有效地诱导PAPE对CMJ性能.
- 由于IFw协议引起的过度疲劳,CMJ性能没有得到改善.
- 需要进一步的研究,以探索最佳的IFw加载参数,并为引起PAPE设置体积.

01:22Muscle Stimulation Frequency
2.2K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.

1.4K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
