概括
静态拉伸练习的顺序会影响运动范围 (ROM) 的改善. 拉伸相同的肌肉群两次或第二个肌肉群在一个序列中产生显著的ROM收益,没有 contralateral肢体效应.
科学领域:
- 生物力学 生物力学
- 运动生理学 运动生理学
- 体育科学 运动科学 运动科学
背景情况:
- 运动范围 (ROM) 对于身体功能至关重要.
- 伸展炼对ROM结果的影响尚未完全理解.
- 研究拉伸序列优化了灵活性干预措施.
研究的目的:
- 为了确定静态拉伸 (SS) 的管理顺序是否会影响运动范围 (ROM) 的结果.
- 分析顺序与单个肌肉组在下肢伸展的特定影响.ROM.
- 评估对对侧肢的潜在交叉效应.
主要方法:
- 108名参与者被随机分为五组:膝盖延伸器 (KE),膝盖曲器 (KF),KE然后KF,KF然后KE,和控制 (CG).
- 八组30s单边静态拉伸与30s休息被应用到右腿.
- 被动部延伸 (PHE) 和被动直腿提升 (PSLR) 测量了手术前,手术后和手术后15分钟的ROM.
主要成果:
- 在对照组中没有观察到时间依赖的ROM变化.
- 在KE和KF/KE组中,干预后立即注意到PHE的显著增加.
- 干预后立即在KF和KE/KF组中观察到PSLR的显著增加,没有副作用.
结论:
- 静态拉伸的顺序显著影响运动范围的改进.
- ROM增益主要观察到在最后一组肌肉伸展或在顺序伸展同一组肌肉时.
- 伸展干预似乎不会对非伸展的四肢产生交叉效应.

01:22Muscle Stimulation Frequency
2.3K
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.

01:16Crossover Experiments
2.9K
Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
