Trained men in two age groups, 30-39 (n = 12) and 60-69 (n = 13), each performed at the Multiple Task Performance Battery in four separate full-day sessions with and without alcohol (2.2 ml of 100-proof vodka per kilogram of body weight) at ground level and at a simulated altitude of 12,500 ft (3,810 m). Subjects breathed appropriate gas mixtures through oxygen masks at both ground level and altitude. Mean breathalyzer readings peaked near 88 mg% and did not differ between age groups or altitude conditions. Younger subjects performed better than older subjects; performance of both age groups was significantly impaired by alcohol but these adverse effects were greater for the older subjects. No significant effects on performance were obtained due to altitude or to the interaction of altitude with alcohol. These results and those from several other studies suggest that prevalent views regarding the nature of the combined effects of alcohol and altitude on blood alcohol levels and on performance need to be redefined.
两个年龄组（30 - 39岁，n = 12；60 - 69岁，n = 13）的受过训练的男性，每人在多任务表现测试组中，于地面和模拟海拔12500英尺（3810米）的高度下，分别进行了四次单独的全天测试，测试时有的饮酒（每千克体重摄入2.2毫升100度伏特加），有的不饮酒。受试者在地面和高海拔时都通过氧气面罩呼吸合适的气体混合物。平均呼气酒精含量读数在接近88毫克%时达到峰值，且在年龄组或海拔条件之间没有差异。年轻受试者比年长受试者表现更好；两个年龄组的表现都因酒精而显著受损，但这些不利影响对年长受试者更大。海拔或海拔与酒精的相互作用对表现没有显著影响。这些结果以及其他几项研究的结果表明，关于酒精和海拔对血液酒精水平及表现的综合影响性质的普遍观点需要重新定义。
