Abstract

The purpose of this study was to investigate the effects of diet on cognition and flight performance of 45 pilots. Based on a theory of self-care, this clinical study used a repeated-measure, counterbalanced crossover design. Pilots were randomly rotated through 4-day high-carbohydrate, high-protein, high-fat, and control diets. Cognitive flight performance was evaluated using a GAT-2 full-motion flight simulator. The Sternberg short-term memory test and Vandenberg's mental rotation test were used to validate cognitive flight test results. Pilots consuming a high-protein diet had significantly poorer ( < .05) overall flight performance scores than pilots consuming high-fat and high-carbohydrate diets.

摘要

本研究的目的是调查饮食对45名飞行员认知和飞行表现的影响。基于自我护理理论,本临床研究采用了重复测量、平衡交叉设计。飞行员被随机安排轮流采用为期4天的高碳水化合物、高蛋白、高脂肪和对照饮食。使用GAT-2全动飞行模拟器评估认知飞行表现。采用斯特恩伯格短期记忆测试和范登伯格心理旋转测试来验证认知飞行测试结果。与食用高脂肪和高碳水化合物饮食的飞行员相比,食用高蛋白饮食的飞行员总体飞行表现得分显著更低(P<0.05)。
