The metabolic and behavioral effects of nutrients after exercise on vigilance level, performance, and mood have been minimally studied and have given contradictory results. In order to increase the understanding of the relationships between nutrition, exercise and performance, this experiment compared the effects on mood and performance of a protein- rich meal and a protein- poor meal, eaten just after an acute session of exercise. Vigilance and mood were evaluated by visual analog scales, and memory was measured by memory search task from the AGARD STRES battery, based on the Sternberg paradigm. Forty-two subjects were involved in this experiment. All subjects participated in the study of the effect of exercise after two kinds of meals (protein and nonprotein). Two groups of fourteen subjects we used to evaluate the effect of the exercise and the effect of the delay of meal intake after exercise in the two kinds of diet. The results show no difference in memory performance between exercise and rest conditions, nor between "protein" and "no protein" meal groups. They do show, however, that subjects feel happier after a meal with protein than after a meal without protein. The effects of the "no protein" meal on drowsiness differ with the glucide content of the meal. Subjects are less drowsy when they eat between 125 and 150 g of glucide than when they eat more than 150 g. The rousing effect induced by physical exercise is counterbalanced when subjects eat more than 150 g of carbohydrate. The anxiolytic effect of glucide is re-established.
运动后营养物质对警觉水平、表现和情绪的代谢及行为影响的研究极少，且结果相互矛盾。为了增进对营养、运动和表现之间关系的理解，本实验比较了在一次急性运动后立即食用富含蛋白质的餐食和缺乏蛋白质的餐食对情绪和表现的影响。通过视觉模拟量表评估警觉性和情绪，并基于斯特恩伯格范式，使用AGARD STRES电池中的记忆搜索任务来测量记忆力。42名受试者参与了本实验。所有受试者都参与了两种餐食（含蛋白质和不含蛋白质）后运动效果的研究。两组各14名受试者被用于评估两种饮食中运动的效果以及运动后进食延迟的影响。结果显示，运动和休息条件之间、“含蛋白质”和“不含蛋白质”餐食组之间在记忆表现上没有差异。然而，结果确实表明，与食用不含蛋白质的餐食后相比，受试者在食用含蛋白质的餐食后感觉更快乐。“不含蛋白质”餐食对嗜睡的影响因餐食中的碳水化合物含量而异。当受试者摄入125至150克碳水化合物时比摄入超过150克时更不容易嗜睡。当受试者摄入超过150克碳水化合物时，体育锻炼所产生的提神效果会被抵消。碳水化合物的抗焦虑效果得以恢复。
