每日补充原蛋白 (CP) 显著增加了年轻男性的肌肉和肌硬度. 这种肌肉刚度的增强有助于改善爆炸性肌肉力量,表明CP是运动表现的潜在营养辅助.
科学领域:
- 运动科学 运动科学 运动科学
- 营养生物化学 营养生物化学
- 生物力学 生物力学
背景情况:
- 原 (CP) 因其在结合组织健康和肌肉功能方面的潜在益处而被广泛研究.
- 了解CP对肌肉和肌机械性能的特定影响对于优化运动表现和预防伤害至关重要.
研究的目的:
- 调查16周每日补充原蛋白 (CP) 对肌肉和肌硬度的影响.
- 评估CP对爆炸性肌肉力量的影响,特别是扭矩发展速度 (RTD).
主要方法:
- 这是一项双盲,随机,安慰剂控制的试验,涉及50名健康的年轻,久坐不动的男性.
- 参与者每天接受10克CP或安慰剂,持续16周.
- 干预前后测量肌肉和肌刚性,横截面积 (CSA),最大自发同度收缩 (MVC) 扭矩和RTD.
主要成果:
- 在CP组中,中部胃肌 (MG) 肌肉硬度和阿基里斯肌硬度显著增加.
- 在CP组中观察到扭矩发展正常化速度 (RTD) 的显著改善.
- 在两组中都没有发现MG或阿基勒斯CSA或MVC扭矩的显著变化. 在MG硬度和正常化的RTD之间发现了积极的相关性.
结论:
- 每日补充CP有效地增加了健康的年轻男性的肌肉和肌硬度.
- 观察到的肌肉刚性的增强似乎是提高爆炸性肌肉力量的关键因素.
- 补充CP可能是一个有价值的营养策略来提高运动表现,特别是在动力和速度主导的活动中.
