本研究通过研究耐力运动训练是否会导致对心理社会应激的生理应激反应减少，实验验证了交叉应激适应假说。我们将149名健康男性随机分配到为期12周的运动训练、放松训练或等待名单对照组。在干预前后，我们评估了各组的身体健康（乳酸盐测试），并根据唾液游离皮质醇、心率（HR）和心率变异性（HRV），将他们的生理应激反应与特里尔社会应激测试进行比较;最终样本由96名受试者组成。正如假设的那样，运动训练显着改善健身和减少所有三个参数的应激反应，但是，它只改善了应激恢复的HR。放松计划只减少皮质醇，但没有HR或HRV反应，没有变化出现的对照组。研究结果表明，跨应激适应假说是有效的心血管以及内分泌应激反应。
The present study experimentally tested the cross-stressor adaptation hypothesis by examining whether endurance exercise training leads to reductions in the physiological stress response to a psychosocial stressor. We randomly assigned 149 healthy men to a 12-week exercise training, relaxation training, or a wait list control group. Before and after intervention we assessed the groups' physical fitness (lactate testing) and compared their physiological stress responses to the Trier Social Stress Test for Groups in terms of salivary free cortisol, heart rate (HR) and heart rate variability (HRV); the final sample consisted of 96 subjects. As hypothesized, the exercise training significantly improved fitness and reduced stress reactivity in all three parameters; however, it only improved stress recovery in terms of HR. The relaxation program reduced only cortisol, but not HR or HRV reactivity; no changes emerged for the control group. The findings suggest that the cross-stressor adaptation hypothesis is valid for cardiovascular as well as endocrine stress reactivity.
