运动周围的蛋白质计时不会显著影响瘦体质量. 虽然运动前蛋白质可以增强下肢力量,但需要更多的研究才能得出关于力量增加的最终结论.
科学领域:
- 运动生理学 运动生理学
- 营养科学 营养科学
- 运动医学 运动医学
背景情况:
- 肌肉的力量和质量对于运动表现和健康至关重要.
- 以前的元分析表明,蛋白质定时与肌肉增长无关.
- 这些分析并没有直接比较研究中的运动前和运动后的蛋白质摄入量.
研究的目的:
- 对直接比较运动前与运动后蛋白质摄入量的研究进行元分析.
- 评估蛋白质定时对肌肉力量和肌肉量的影响.
主要方法:
- 搜索了PubMed,科学网络和Scopus数据库,直到2024年1月.
- 包括随机对照试验 (RCT) 与至少4周的运动前或运动后蛋白质摄入量.
- 对强度和瘦体质量结果进行了随机效应元分析.
主要成果:
- 蛋白质定时对瘦体质没有显著影响 (SMD: -0.08).
- 对胸部压力没有显著影响 (SMD:0.07).
- 一个趋势表明运动前蛋白质增强了腿部压力 (SMD:0.70),但小组分析缺乏意义 (p=0.07).
结论:
- 蛋白质的时间对运动诱导的瘦体质量变化的影响很小.
- 对上肢和下肢强度的潜在差异性影响需要进一步研究.
- 需要更多的研究来证实蛋白质定时对强度适应的影响.

Exercise and Muscle Performance
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...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
