检查卵巢功能对心理生理应激反应的影响，并确定有氧运动是否减少应激反应。五十名绝经前和绝经后妇女最初接受了公开演讲任务和额头冰敷手术，在此期间监测她们的血压和心率并获取连续的血液样本。受试者还通过最大运动跑步机测试进行了有氧健身评估。然后受试者被随机分配到为期 12 周的有氧运动（例如，以规定的运动强度步行和慢跑）或非有氧力量和灵活性训练的锻炼计划，然后进行重新评估。结果表明，与绝经前女性相比，绝经后女性的静息肾上腺素水平较低，但肾上腺素对说话任务的反应性较高。绝经前和绝经后女性在寒冷挑战期间的心血管或儿茶酚胺反应没有差异。绝经前和绝经后女性在有氧健身方面也取得了相当的改善。然而，精神压力测试的结果很复杂，只能部分支持有氧运动在减轻压力反应方面的作用。
Examined the influence of ovarian function on psychophysiological stress responses and determined if aerobic exercise reduced stress reactivity. Fifty premenopausal and postmenopausal women initially were subjected to a public speaking task and an ice-on-the-forehead procedure, during which time their blood pressure and heart rate were monitored and continuous blood samples were obtained. Subjects also underwent aerobic fitness evaluations with a maximum-exercise treadmill test. Subjects were then randomly assigned to a 12-week exercise program of either aerobic exercise (eg, walking and jogging at a prescribed exercise intensity) or non-aerobic strength and flexibility training and were then reevaluated. Results indicated that postmenopausal women exhibited lower resting epinephrine levels but greater epinephrine reactivity to the speaking task compared to the premenopausal women. There were no differences between premenopausal and postmenopausal women with respect to cardiovascular or catecholamine responses during the cold challenge. Premenopausal and postmenopausal women also achieved comparable improvements in aerobic fitness. However, results of the mental stress testing were complex and provided only partial support for the role of aerobic exercise in reducing stress responses.
