The effect of alcohol consumption on the restoration of fluid and electrolyte balance after exercise-induced dehydration [2.01 +/- 0.10% (SD) of body mass] was investigated. Drinks containing 0, 1, 2, and 4% alcohol were consumed over 60 min beginning 30 min after the end of exercise; a different beverage was consumed in each of four trials. The volume consumed (2,212 +/- 153 ml) was equivalent to 150% of body mass loss. Peak urine flow rate occurred later (P = 0.024) with the 4% beverage. The total volume of urine produced over the 6 h after rehydration, although not different between trials (P = 0.307), tended to increase as the quantity of alcohol ingested increased. The increase in blood (P = 0.013) and plasma (P = 0.050) volume with rehydration was slower when the 4% beverage was consumed and did not increase to values significantly greater than the dehydrated level (P = 0.013 and P = 0.050 for blood volume and plasma volume, respectively); generally, the increase was an inverse function of the quantity of alcohol consumed. These results suggest that alcohol has a negligible diuretic effect when consumed in dilute solution after a moderate level of hypohydration induced by exercise in the heat. There appears to be no difference in recovery from dehydration whether the rehydration beverage is alcohol free or contains up to 2% alcohol, but drinks containing 4% alcohol tend to delay the recovery process.
研究了饮酒对运动诱发脱水[体重的2.01±0.10%（标准差）]后体液和电解质平衡恢复的影响。运动结束30分钟后开始，在60分钟内饮用含0%、1%、2%和4%酒精的饮料；在四项试验中，每次饮用不同的饮料。饮用的量（2212±153毫升）相当于体重减轻量的150%。饮用含4%酒精的饮料后，尿流率峰值出现得较晚（P = 0.024）。补液后6小时内产生的尿液总量，尽管各试验间无差异（P = 0.307），但随着摄入酒精量的增加有增加的趋势。饮用含4%酒精的饮料时，补液后血液（P = 0.013）和血浆（P = 0.050）量的增加较慢，且未增加到显著高于脱水水平的值（血液量和血浆量分别为P = 0.013和P = 0.050）；一般来说，增加量是摄入酒精量的反函数。这些结果表明，在热环境中运动引起适度脱水后，饮用稀溶液酒精饮料时，酒精的利尿作用可忽略不计。补液饮料不含酒精或含高达2%酒精时，脱水恢复情况似乎没有差异，但含4%酒精的饮料往往会延迟恢复过程。
