Two experiments are proposed. Each is designed to provide the background for a line of research aimed at examining the potential therapeutic effects of physical activity among individuals diagnosed with a mood disorder. This proposal considers the effect of exercise on emotional responsiveness in dysphoric individuals. The purpose of experiment one is to examine facial electromyographic (EMG), heart rate, blood pressure, and skin conductance responses during sustained periods of pleasant, neutral, and unpleasant picture viewing in dysphoric and non-dysphoric individuals who vary in their self-reported level of physical activity. It is predicted that dysphoric individuals will exhibit a blunted emotional responsiveness to arousing pleasant stimuli, and furthermore, that this effect will be greater among non-physically active individuals. The purpose of experiment two is to examine the effect of acute physical exercise, compared to a resting control condition, on psychophysiological responses during emotional picture viewing in dysphoric compared to non-dysphoric individuals. It is predicted that exercise will activate the appetitive emotional system in dysphoric individuals and restore appetitive emotional responsiveness. In addition, aerobic fitness is expected to be positively related to emotional responsiveness to both pleasant and unpleasant stimuli at baseline in both groups of individuals. The largest effect for restoring pleasant emotional responsiveness is expected to occur in the least aerobically fit dysphoric individuals.

提出了两个实验。每个人都旨在为一系列研究提供背景，旨在检查被诊断为情绪障碍的个体中体育活动的潜在治疗作用。该提议考虑了运动对烦躁不安的情感反应能力的影响。实验的目的是检查面部肌电图（EMG），心率，血压和皮肤电导反应在持续的愉悦，中性和不愉快的图像中，在烦躁不安和非疾病的个体中观察，他们自我报告的体育活动水平各不相同。据预测，烦躁不安的人会表现出令人沮丧的情感反应能力 刺激，此外，在非物理活性个体中这种效果将更大。实验二的目的是检查急性体育锻炼的影响，与静息控制条件相比，与非偶然的个体相比，在烦躁不安的情绪图片观察期间的心理生理学反应。可以预测运动会激活 烦躁的个体中的狂热情绪系统，并恢复食欲的情感反应能力。此外，有氧健身有望与两组个体的基线时对基线时愉快和不愉快刺激的情绪反应呈正相关。预计恢复令人愉悦的情绪反应能力的最大效果预计将发生在最小的有氧运动烦躁的个体中。
