概括

碳水化合物电解质饮料中的乳清蛋白分离物与单独的素或碳水化合物电解质溶液相比,显著改善了运动后的补水和耐力能力. 这项研究强调了乳清.

科学领域:

运动生理学运动生理学
运动营养运动营养
人类表现的人类表现.

背景情况:

摄入蛋白质可以增强运动后的补水能力,但不同类型蛋白质的影响尚不清楚.
了解蛋白质在补水中的作用对于运动员和积极活动的人来说至关重要.

研究的目的:

为了比较乳清分离剂与添加到碳水化合物电解质 (CE) 饮料中的蛋白对运动后补水的影响.
评估这些增强蛋白质的CE饮料对后续耐力能力的影响.

主要方法:

30名男性士兵在炎热,潮湿的条件下跑来跑去失去~2.2%的体重.
参与者饮用了CE饮料,CE与乳清分离物 (CEW) 或CE与素 (CEC).
在3小时内测量了液体平衡和保持量,随后进行了2.4公里的耐力能力运行测试.

主要成果:

液体平衡最高的是CEW (0.22L),其次是CEC (0.19L) 和CE (0.12L).
与CE (76.67%) 和CEC (78.65%) 相比,CEW试验 (80.35%) 的平均液体保留率最大.
耐力能力 (运行时间) 与CEW相比,CEC和CE显著更好.

结论:

在CE饮料中的乳清蛋白分离物显著改善了补水结果.
虽然CEW增强了补水,但CEC和CE单独支持更好的耐力表现.

Strength and Heat of Hydration

Strength and Heat of Hydration

The hydration of cement is an exothermic reaction in which heat is generated as cement hydrates. This heat of hydration is critical to cement's strength development. The rate at which this heat is generated affects the temperature rise, with a majority of the heat being released early in the hydration process, half within the first three days, and about 75% within the first week.
The heat of hydration for each cement compound is significant; for instance, tricalcium aluminate (C3A) and...

Body Water Content and Fluid Compartments

Body Water Content and Fluid Compartments

Life's biochemical processes occur within aqueous solutions. Solutes are substances that are dissolved within these solutions. The human body contains a variety of solutes, which can differ across various body parts. These can encompass proteins—such as those responsible for clotting and carbohydrate transport—as well as electrolytes. In medicine, an electrolyte is often described as a mineral ion derived from a salt possessing an electric charge. Examples include sodium ions...
