患者;有氧适应性与许多生理适应有关，这些生理适应使身体压力更有效地应对。本实验考察了有氧健身是否会影响情绪反应。心率、生化指标（儿茶酚胺、皮质醇、催乳素、乳酸）、自我报告的觉醒和焦虑在暴露于一系列社会心理压力源之前、期间和之后的不同时间点对15名训练有素的和15名未训练的受试者进行监测。两组的心率和主观觉醒水平在应激过程中均显著升高。受训练的受试者在压力期早期表现出较高的去甲肾上腺素和催乳素水平，在压力源后心率恢复得更快，在训练结束时焦虑水平较低。这种更快的心率和主观从心理社会压力中恢复，表明有氧训练的个体可能在生理和主观情绪方面都能够更快地恢复。根据处理情绪反应适应性的模型，讨论了有氧训练和未训练的反应性特征的差异。
&NA; Aerobic fitness is associated with numerous physiological adaptations which permit physical stress to be coped with more efficiently. The present experiment examined whether aerobic fitness influences emotional response. Heart rate, biochemical measures (catecholamines, cortisol, prolactin, lactic acid), and self‐reported arousal and anxiety were monitored in 15 highly trained and 15 untrained subjects at various points before, during and following exposure to a series of psychosocial stressors. Heart rate and subjective arousal level increased markedly during the stressors in both groups. Trained subjects showed higher levels of norepinephrine and prolactin early in the stress period, more rapid heart rate recovery following the stressors, and lower levels of anxiety at the conclusion of the session. This more rapid heart rate and subjective recovery from psychosocial stress, suggests that aerobically trained individuals may be capable of faster recovery in both physiological and subjective dimensions of emotionality. The differences in reactivity profiles between the aerobically trained and untrained were discussed in light of models that have dealt with the adaptiveness of emotional response.
