To investigate the effects of glycogen depleting exercise and dietary composition on mood, 14 males completed the Profile of Mood States (POMS) questionnaire under four conditions. A control condition (CON) of ad libitum diet preceded any experimental manipulation. Subsequently, three treatments were administered randomly in a counterbalanced design: a) following a glycogen-depletion protocol and 3 d on a high-carbohydrate diet (93% of total caloric intake as carbohydrate [CHO]), b) following a glycogen-depletion protocol and 3 d on a low-CHO diet (23% of total caloric intake as CHO), and c) following 3 d of recorded ad libitum dietary consumption. Conditions a and b simulated phases of popular glycogen-loading protocols, and condition c served as a second control condition confirmed by records of dietary intake. The POMS measured tension-anxiety, depression-dejection, anger-hostility, vigor-activity, fatigue-inertia, and confusion-bewilderment. A composite score of total mood disturbance (TMD) was computed by summing the subscale scores (weighting vigor-activity negatively). Dietary composition (fat, protein, and CHO content) differed significantly (P less than 0.001) among the three treatments, but total caloric intake was not different. No significant differences were found among the treatment and control conditions for TMD or any POMS subscale score. We find no evidence that the 3-d glycogen loading protocol we employed with healthy, moderately fit, young males can be expected to confound performance measures by altering mood.
为研究糖原消耗运动和饮食组成对情绪的影响，14名男性在四种条件下完成了情绪状态剖面图（POMS）问卷。在进行任何实验操作之前，先设置了自由饮食的对照条件（CON）。随后，采用平衡设计随机给予三种处理：a）遵循糖原消耗方案并在高碳水化合物饮食（碳水化合物[CHO]占总热量摄入的93%）下进食3天，b）遵循糖原消耗方案并在低碳水化合物饮食（CHO占总热量摄入的23%）下进食3天，c）记录自由饮食3天的摄入量。条件a和b模拟了流行的糖原负荷方案的阶段，条件c作为通过饮食摄入量记录确认的第二个对照条件。POMS测量紧张焦虑、抑郁沮丧、愤怒敌意、活力活动、疲劳惰性和困惑迷茫。通过将各子量表得分相加（活力活动得分取负）计算出总情绪紊乱（TMD）的综合得分。三种处理之间的饮食组成（脂肪、蛋白质和CHO含量）差异显著（P<0.001），但总热量摄入无差异。在TMD或任何POMS子量表得分方面，处理组和对照组之间未发现显著差异。我们没有发现证据表明，我们对健康、适度健康的年轻男性采用的3天糖原负荷方案会因改变情绪而混淆性能指标。
