概括
当调节活动负载在最佳功率负载 (OPL) 以上或以下20%时,后激活性能增强 (PAPE) 是相似的. 这表明最优的力量训练可能不需要最大限度地提高PAPE对垂直跳跃性能的影响.
科学领域:
- 运动生理学 运动生理学
- 运动科学 运动科学 运动科学
- 生物力学 生物力学
背景情况:
- 后激活性能增强 (PAPE) 描述了在调节活动 (CA) 后肌肉性能的急剧增加.
- 当前的CA处方通常依赖于一次重复最大的百分比,忽视了最佳功率区域.
- 接近最佳功率负载 (OPL) 的调节活动强度对PAPE的影响仍未得到充分研究.
研究的目的:
- 调查调节活动负载在最佳功率负载 (OPL) 以上20%和以下20%对随后的垂直跳跃性能的影响.
- 为了确定在最佳功率区域附近的训练是否会影响后激活性能增强反应.
主要方法:
- 15名经过娱乐训练,至少有一年阻力训练经验的个人参加了比赛.
- 对于每个参与者来说,确定了跳的最佳动力负载 (OPL).
- 参与者完成了两项平衡的方案:跳在+20%OPL和-20%OPL,垂直跳跃性能在训练前和训练后进行评估.
主要成果:
- 统计分析显示,条件对跳跃高度和功率有显著的主要影响,但后期测试显示条件之间没有显著差异.
- 在将基线性能与最佳后调节试验进行比较时,没有发现显著的主要效应或相互作用.
- 配对的t测试表明,在+20%OPL和-20%OPL条件之间,跳跃高度或功率的相对变化没有显著差异.
结论:
- 负载在20%以上或以下的最佳功率负载引起类似的后激活性能增强效应在随后的垂直跳跃性能.
- 这些发现表明,在这种情况下,精确地定位最佳功率区域可能对优化PAPE并不至关重要.

Muscle 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.

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...
