We studied the effects of several fluid replacements taken after squash on exercise-related metabolic responses. 12 subjects played 5 games and after each game were assigned one of the following, receiving a different one each time: (1) no fluid replacement, or 500 ml of (2) water, (3) electrolyte solution, (4) glucose solution or (5) a glucose/electrolyte 'sports' drink. Circulating levels of lactate, free fatty acids, glucose, potassium, sodium and plasma osmolality were measured at rest and at 5, 15, 30 and 60 min after games. There were significant changes over time for all measured variables (p < 0.001). The only effect of these drinks was by the glucose-containing drinks, which resulted in significant elevation of blood glucose levels (p < 0.001); no effects on circulating electrolyte levels were demonstrated. In conclusion, while fluid replacements may increase glucose levels, electrolyte levels are not affected by drinks which are commonly used after squash.
我们研究了壁球运动后饮用几种补液对运动相关代谢反应的影响。12名受试者进行了5场比赛,每场比赛后被分配以下其中一种饮品,每次饮用不同的饮品:(1)不补液,或500毫升的(2)水、(3)电解质溶液、(4)葡萄糖溶液或(5)葡萄糖/电解质“运动”饮料。在休息时以及比赛后的5、15、30和60分钟测量乳酸、游离脂肪酸、葡萄糖、钾、钠的循环水平以及血浆渗透压。所有测量变量随时间均有显著变化(p < 0.001)。这些饮品的唯一作用是含葡萄糖的饮品,其导致血糖水平显著升高(p < 0.001);未显示对循环电解质水平有影响。总之,虽然补液可能会提高血糖水平,但电解质水平不受壁球运动后常用饮品的影响。
