背景：人们普遍认为，适度的有氧运动会导致饮食结构的变化，特别是增加碳水化合物的摄入量，但会减少脂肪的摄入量。目的：目的是确定监督下的长期运动计划对久坐、超重和中度肥胖的男性和女性大量营养素摄入的影响。设计：从大学和周边社区招募参与者（n = 74），并随机分配到运动组或对照组。在监督下进行中等强度的锻炼，每天 45 分钟，每周 5 天。饮食摄入是随意的，并在基线和 16 个月研究中的其他 5 个场合通过称重和测量技术测量了能量和常量营养素成分。每次测量都包括在大学食堂进行为期两周的直接测量。通过多次24小时饮食回忆程序测量2周期间食堂外的食物消耗量（即零食）。结果：从基线到16个月，运动组和对照组之间的男性或女性在脂肪、碳水化合物或蛋白质摄入量（以克或总能量摄入量的百分比表示）方面没有显着差异。结论：16个月的中等强度运动不会显着改变年轻人的常量营养素摄入量。
Background: It is commonly believed that moderate aerobic exercise leads to changes in diet composition, specifically, an increase in carbohydrate intake at the expense of fat intake.Objective: The goal was to determine the effects of a supervised, long-term program of exercise on the macronutrient intake of previously sedentary, overweight and moderately obese men and women.Design: Participants (n = 74) were recruited from the university and surrounding communities and were randomly assigned to the exercise or control group. Exercise of moderate intensity was performed for 45 min/d, 5 d/wk, under supervision. Diet intake was ad libitum and was measured for energy and macronutrient composition at baseline and at 5 other occasions across the 16-mo study by use of weighing and measuring techniques. Each measurement consisted of a 2-wk period of direct measurement in the university cafeteria. Food consumption outside the cafeteria during the 2-wk periods (ie, snacks) was measured by multiple-pass 24-h dietary recall procedures.Results: There were no significant differences for men or women between the exercise and control groups from baseline to 16 mo in fat, carbohydrate, or protein intake expressed as grams or as percentages of total energy intake.Conclusion: Sixteen months of exercise of moderate intensity does not measurably alter the macronutrient intake of young adults.
