概括
这项研究比较了两名游泳运动员的电肌图 (EMG) 活动.
科学领域:
- 运动医学 运动医学
- 生物力学 生物力学
- 运动生理学 运动生理学
背景情况:
- 游泳者的肩膀是竞技游泳者常见的伤害.
- 强度计划是有效的预防,但电肌图 (EMG) 分析是缺乏的.
- 了解肌肉激活模式对于优化预防性炼至关重要.
研究的目的:
- 为了比较两个不同的游泳者肩部预防计划期间关键肩部肌肉 (中间梯形,下梯形,中脊,前脊,大胸部) 的EMG活动.
- 在使用弹性带与重量进行相同的运动时,调查肌肉激活的差异.
- 为游泳者提供有关优化肩伤预防策略的见解.
主要方法:
- 20名竞技游泳运动员参与了这项研究.
- 进行了两种不同的五项运动强度计划:一种是弹性带,一种是重量.
- 从五个肩部肌肉的表面EMG数据被记录在1000Hz,并使用统计分析 (配对样本T测试或Wilcoxon测试) 进行比较.
主要成果:
- 诸如90度内外旋转等运动显示了具有弹性带的高肌肉活动 (分别p < 0.001和p ≤ 0.01).
- 当使用重量 (p < 0.001) 进行时,骨拳的EMG活性很高 (p < 0.001).
- 当使用不同的仪器 (弹性带与重量) 进行相同的练习时,观察到肩膀肌肉肌电活动的显著变化.
结论:
- 设备的选择 (弹性带与重量) 在游泳者预防性炼期间显著影响肩膀肌肉的EMG活动.
- 不同的练习会引起不同的肌肉激活模式,这取决于所使用的抵抗工具.
- 这种变化凸显了在为游泳者设计和实施肩部伤害预防计划时考虑设备特定的肌肉参与的重要性.

Exercise and Muscle Performance
6.2K
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...

Muscles of the Shoulder
9.4K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.
