概括

牛乳粉 (COL) 补充剂没有显著改善运动员的游泳表现. 然而,COL和安慰剂都对运动适应产生了类似的影响,这表明高质量的牛奶蛋白可能同样有效.

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:

牛乳粉 (COL) 富含免疫因子和生长因子.
COL被认为具有潜在的 ergogenic 和免疫学益处.
这项研究调查了COL对耐力运动员的影响.

研究的目的:

为了评估12周COL补充剂对游泳表现的影响.
评估COL对男性运动员炼适应性的影响.
为了在训练有素的游泳运动员和三项运动员中比较COL与安慰剂.

主要方法:

随机,双盲,安慰剂控制的交叉设计.
28名男性运动员在12周内每天接受25g的COL或安慰剂.
测量了游泳特异性表现 (SSP),心率 (HR) 和血液乳糖 ([La]).

主要成果:

COL并没有显著增强SSP.
运动后血液中的乳酸盐 ([La]) 降低了COL和安慰剂.
HR没有受到任何补充的影响.
在SSP结果中观察到潜在的实践效应.

结论:

COL和高质量的牛奶蛋白 (安慰剂) 显示了可比的运动适应性.
实践效应可能会影响长期研究中的绩效结果.
生物化学和生理学标记物对实践效应的敏感性较小.

Exercise and Muscle Performance

Exercise and Muscle Performance

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...
