概括
可变阻力训练 (VRT) 和持续阻力训练 (CRT) 显示了类似的长期力量增长. 特定的VRT比率提高了明显的下肢性能,其中35%的VRT是爆炸力最佳的.
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:
- 对于下肢力量和功率,在可变阻力训练 (VRT) 中可变阻力与恒定的最佳阻力比率尚未得到很好的定义.
- 了解这些比率对于优化培训协议至关重要.
研究的目的:
- 调查VRT中不同变量与恒定的阻力比对下肢强度和功率的影响.
- 为了比较20%的VRT和35%的VRT与持续抵抗训练 (CRT) 的疗效.
主要方法:
- 45名男性大学生被分为三组:20%的VRT,35%的VRT和CRT.
- 所有组都接受了为期6周的式训练,每周两次以80%的1RM进行.
- 绩效指标包括1RM,跳跃测试 (CMJ,SJ,SBJ),20米冲刺和直骨大腿横截面积 (RFCSA).
主要成果:
- 所有训练组都显示了随着时间的推移显著的力量改善.
- 与CRT相比,35%的VRT组表现出明显更大的跳 (SJ) 改善.
- 在最大力量,反运动跳跃 (CMJ),站立宽跳跃 (SBJ),冲刺时间或RFCSA之间没有观察到显著差异.
结论:
- 变性阻力训练 (VRT) 和持续阻力训练 (CRT) 导致可比的长期力量适应.
- 不同的VRT阻力比率在下肢表现中诱导不同的任务特定适应.
- 建议使用35%的VRT协议来增强静态爆炸任务,而20%的VRT可以作为补充强度工具.

Exercise and Muscle Performance
1.3K
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...

Design Example: Frog Muscle Response
186
A student is tasked to work on an intriguing experiment involving an RL (Resistor-Inductor) circuit to study the muscle response of a frog's leg to electrical stimulation. The RL circuit plays a crucial role in this experiment, providing the means to control and measure the electrical impulses that trigger muscle contraction.
When the switch connecting the RL circuit is closed, a brief muscle contraction is observed. This is because, at a steady state, the inductor acts like a short...
