长期以来，体育活动一直被认为对健康有益，经常锻炼据称可以缓解压力。然而，证明这些影响的经验证据有限。在这项研究中，我们比较了进行或不进行定期体育锻炼的个体对急性社会心理压力源的心理生理反应。健康男性和女性（N= 111）参加了两项实验，一项是特里尔社会压力测试（TSST），另一项是无压力控制任务。我们测量了任务前后的心率、血压、皮质醇和自我报告的情绪。每周至少锻炼一次的人在休息时的心率比不锻炼的人低，但两组对TSST的心血管反应没有差异。习惯性运动的水平并不影响任务前自我报告的情绪，但与锻炼者相比，非锻炼者在TSST后报告的积极情绪下降幅度更大。这些发现为有规律的锻炼可以防止压力带来的负面情绪影响的说法提供了适度的支持，并表明锻炼对健康个体有有益的影响。这些发现受其相关性的限制，未来需要对定期运动对急性应激反应的影响进行前瞻性对照研究。
Physical activity has long been considered beneficial to health and regular exercise is purported to relieve stress. However empirical evidence demonstrating these effects is limited. In this study, we compared psychophysiological responses to an acute psychosocial stressor between individuals who did, or did not, report regular physical exercise. Healthy men and women (N= 111) participated in two experimental sessions, one with the Trier Social Stress Test (TSST) and one with a non-stressful control task. We measured heart rate, blood pressure, cortisol, and self-reported mood before and at repeated times after the tasks. Individuals who reported physical exercise at least once per week exhibited lower heart rate at rest than non-exercisers, but the groups did not differ in their cardiovascular responses to the TSST. Level of habitual exercise did not influence self-reported mood before the tasks, but non-exercisers reported a greater decline in positive affect after the TSST in comparison to exercisers. These findings provide modest support for claims that regular exercise protects against the negative emotional consequences of stress, and suggest that exercise has beneficial effects in healthy individuals. These findings are limited by their correlational nature, and future prospective controlled studies on the effects of regular exercise on response to acute stress are needed.
