概括

飞轮训练 (FT) 增强下肢的爆炸力,效果在运动后4-8分钟达到顶峰. 激活后性能提升 (PAPE) 的程度取决于训练期间使用的惯性负载.

科学领域:

运动科学运动科学运动科学
运动生理学运动生理学
生物力学生物力学

背景情况:

激活后性能提升 (PAPE) 是一种现象,在此之前的调节活动可以暂时改善随后的肌肉性能.
飞轮训练 (FT) 是一种利用惯性负荷的阻力运动形式,提供了一种独特的方法来潜在地引起PAPE.

研究的目的:

调查飞轮训练在下肢爆炸力方面的PAPE,特别是反运动跳跃 (CMJ) 和30米冲刺.
检查不同惯性负荷 (轻,中轻,深) 对PAPE的幅度和持续时间的影响.

主要方法:

一个随机的交叉设计,涉及20名训练有素的男子.
参与者在基线和FT后的间隔 (0,4,8,12,16分钟) 进行了CMJ和30米冲刺测试,在不同的惯性负荷或对照条件下.
测量包括CMJ高度和30米冲刺时间.

主要成果:

对于CMJ,PAPE在运动后4分钟达到峰值,并减少12分钟,与较高的惯性负载 (深度) 相比,PAPE更大和更早的PAPE.
对于30米冲刺,只有在中轻惯力负荷时才观察到显著的PAPE,在4分钟达到峰值,降低8分钟,主要是由于改进的10-30m分割时间.
纵向爆炸力PAPE随着惯性负载增加,而水平爆炸力PAPE在最大负载时没有观察到.

结论:

惯性负荷显著影响下肢爆炸力中的PAPE响应.
从FT引发PAPE的最佳时间似乎是在运动后4-8分钟内.
FT可以成为增强爆炸力的一种可行的策略,但对于特定的运动类型 (垂直与水平) 负载选择至关重要.

Exercise and Muscle Performance

Exercise and Muscle Performance

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...

Muscle Stimulation Frequency

Muscle Stimulation Frequency

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.
Wave summation
At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...
