定期炼可以增强下肢肌肉结构,从而提高年轻人的有氧能力 (VO2max). 肌肉结构可能表明训练状态.
科学领域:
- 运动生理学 运动生理学
- 生物力学 生物力学
- 人类解剖学 人类解剖学
背景情况:
- 肌肉架构 (厚度,角,带长度) 对于肌肉功能和适应至关重要.
- 年轻成年人肌肉结构和有氧能力之间的联系尚不清楚.
研究的目的:
- 在运动和不运动的年轻人之间比较下肢肌肉结构和有氧能力.
- 研究肌肉结构参数与最大氧气吸收 (VO2max) 之间的关联.
主要方法:
- 52名健康的年轻成年人 (18-35岁) 被分为运动组 (EG,n=26) 和非运动组 (NEG,n=26).
- 超声波成像评估了关键下肢肌肉的肌肉结构 (厚度,角,带长度).
- 在分级跑步机测试中,使用开放电路螺旋计测量测量了最大的氧气吸收 (VO2max).
主要成果:
- 与NEG (37.29 mL·kg−1·min−1) 相比,EG的VO2max (46.95 mL·kg−1·min−1) 显著更高.
- 在EG的巨大的中间肌,巨大的侧肌和前肌肌中观察到更大的笔纹角.
- VO2max与肌肉厚度 (大腿直骨,大中间骨,大侧骨,前骨),大中间骨角和前骨长度有正相关性.
结论:
- 定期运动会诱导下肢肌肉结构的适应,从而可能提高有氧能力.
- 肌肉结构可以作为一个重要的生理指标,一个人的训练状态在年轻人中.
