概括
背后的内复杂休息时间可能会增强反运动跳跃速度的力量发展,但不是推进冲动. 在复杂的训练中最大限度地提高性能,最佳的休息时间至关重要.
科学领域:
- 运动科学 运动科学 运动科学
- 生物力学 生物力学
- 运动生理学 运动生理学
背景情况:
- 复杂的训练使用后激活性能增强 (PAPE) 通过重阻力练习,然后进行爆炸性运动.
- 这些练习之间的内部复杂休息时间 (ICRP) 是至关重要的,但它们的最佳持续时间对于垂直跳跃的性能还没有得到很好的定义.
- 跳跃高度通常用于测量性能,可能会忽视关键的力-时间特征.
研究的目的:
- 为了研究背部坐后可变的胸内周期 (ICRPs) 对垂直跳跃表现的急性影响.
- 分析ICRP对推进冲动 (J prop) 和相应的力时间变量在反运动跳跃 (CMJs) 和式跳跃 (SJs) 的影响.
主要方法:
- 在执行CMJ和SJ之前,14名受试者进行了3次重复最大 (3RM) 背,然后进行了不同的ICRP (0-300秒).
- 独立变量包括ICRP持续时间和跳跃类型 (CMJ,SJ) 在随机的,平衡的设计中.
- 用重复测量ANOVA和对对效应大小来分析跳跃性能指标的对称百分比变化.
主要成果:
- 与没有休息相比,较长的ICRPs (120和300秒) 观察到CMJ平均力量发展速度 (RFD) 的显著增加.
- 随着较长的ICRPs,SJ RFD显著下降,而推进脉冲 (J prop),峰值力和平均力在各种条件中显示出最小的变化.
- 中大效果大小表明CMJRFD的增强,但Jprop的小效果大小表明整体跳跃功率增强有限.
结论:
- 背部可以通过延伸缩短周期强化RFD,特别是在CMJ中,具有最佳ICRP持续时间.
- 似乎ICRP对垂直跳跃的整体推进冲动的影响有限.
- 需要进一步的研究来优化ICRP策略,以满足复杂培训中的特定跳跃类型和性能结果.

Exercise and Cardiovascular Response
771
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Muscle Stimulation Frequency
2.1K
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...

Exercise and Muscle Performance
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...

Muscle Recovery and Fatigue
2.0K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...
