概括
站立的小牛举起比坐着的小牛举起更有效地提高小牛肌肉的大小 (过度缩小). 训练较长的肌肉长度,就像站立运动一样,促进胃半和整体三肌肌肉的更大生长 surae.
科学领域:
- 运动生理学 运动生理学
- 肌肉生物学 肌肉生物学
- 生物力学 生物力学
背景情况:
- 三肌肌群对于运动至关重要,但对抗力训练的反应有限.
- 这种肌肉在不活动期间也容易缩.
- 需要有效的训练策略来治疗三肌 surae 缩.
研究的目的:
- 为了比较站立 (膝盖伸展) 与坐着 (膝盖屈曲) 起腿训练对三肌肌肉缩的影响.
- 研究训练期间肌肉长度对缩结果的影响.
主要方法:
- 14名未经训练的参与者接受了为期12周的小牛养殖培训计划.
- 一只腿被训练在站立,膝盖伸展的位置,和对侧腿在坐着,90度膝盖曲的位置.
- 训练在70%的一次重复最多,每周2次,持续12周.
- 在干预之前和之后,使用磁共振成像评估了三肌肉体的体积.
主要成果:
- 无论是站立还是坐着的小牛,都会增加肌肉体积,在肌肉中增加肌肉体积.
- 与坐着的小牛相比,站立的小牛导致侧面胃角肌,中侧胃角肌和三肌总体体积的显著增加.
- 胃半腹肌在坐着的状态下显示出最小的缩.
结论:
- 站立的小腿举起运动优于坐着的小腿举起,可以诱导胃半和整体三肌的过度缩小.
- 长时间训练肌肉,如在站立姿势中实现的,似乎是促进肌肉缩的关键因素.
- 这些发现表明,运动规划应考虑肌肉的长度,以优化三肌形状的发展.

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...

The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....
