量化3种不同强度运动对皮质醇浓度的影响。10名看起来健康、娱乐活跃的男性参与了研究。在4个不同的场合，受试者被随机分配1小时的周期运动，分别为44.5 +/- 5.5%、62.3 +/- 3.8%和76.0 +/- 6.0%（平均+/- SD）的V(over dot)O(2)峰值和静息对照。在运动前10分钟、20分钟、40分钟和59分钟以及恢复后20分钟采集唾液样本。皮质醇浓度的差异通过多变量方差分析（α = 0.05）进行评估。在最高强度的运动阶段，皮质醇在运动59分钟（p = 0.004）和恢复20分钟（p = 0.016）时显著高于静息对照组的同一时间点。在静息、低强度和中等强度运动中，皮质醇浓度没有显著差异。锻炼
Changes in cortisol concentration in response to exercise at 3 different intensities were quantified. Ten apparently healthy, recreationally active males participated. On 4 separate occasions, subjects were assigned a random order of 1-hour cycle ergometer bouts of exercise at 44.5 +/- 5.5%, 62.3 +/- 3.8%, and 76.0 +/- 6.0% (mean +/- SD) of V(over dot)O(2)peak and a resting control session. Saliva samples were collected before exercise at 10, 20, 40, and 59 minutes of exercise and at 20 minutes of recovery. Differences in cortisol concentration were assessed via multivariate analysis of variance (alpha = 0.05) Tukey post hoc analysis when indicated. During the highest-intensity exercise session, cortisol was significantly higher at 59 minutes of exercise (p = 0.004) and at 20 minutes of recovery (p = 0.016) than at those same time points during the resting control session. No significant differences in cortisol concentration were noted among resting, low-, and moderate-intensity exercise. Exercise
