- 运动科学 运动科学 运动科学
背景情况:
- 间隔的休息时间显著影响了阻力训练的表现.
- 最低速度值 (MVT) 用于客观地确定设置终止.
- 了解最佳休息对于板压力的表现对于培训计划至关重要.
研究的目的:
- 调查一,三,五分钟的休息时间对板压重复的效果.
- 分析不同最小速度值 (MVT0.45和MVT0.35) 对性能的影响.
- 为了确定最佳的休息时间,以保持机械性能,在长椅压力.
主要方法:
- 23名身体活跃的个人 (15名男性,8名女性) 参与了这项研究.
- 参与者完成了四套长椅压力在75%的一次重复最大的最大意图.
- 测试过程包括多种不同的间隔休息时间 (1,3,5分钟) 和MVT (0.45m·s−1,0.35m·s−1).
主要成果:
- 完成的重复次数较少,休息时间较短 (R1 < R3 < R5).
- 速度损失在更多的设置和更短的休息时更大,特别是在MVT0.35.3时.
- 对于MVT0.45,三分钟的休息时间是足够的,而对于MVT0.35,则需要五分钟的休息时间来维持性能.
结论:
- 建议在五分钟的设置间休息时间内,在设置接近故障时 (MVT0.35) 保持长板压力机械性能.
- 当由于故障 (MVT0.45) 进一步终止集时,三分钟的休息时间可能是足够的.
- 休息时间是优化抵抗训练结果和性能维护的关键因素.

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...
