This study was designed to investigate whether post-exercise analgesia occurs following an ad lib exercise routine. All of the 17 male participants exercised on a regular basis. In an exercise setting (student gymnasium) they participated in 20 min of self-selected exercise, while in the neutral setting (laboratory) they rested quietly for 20 min. Pain was induced via the gross pressure device. Pain threshold and pain tolerance were measured twice, with an interval of 20 min, in both the exercise and the neutral setting. Pain threshold was stable in the exercise setting. A significant increase in pain tolerance followed the 20 min bout of exercise, indicating a post-exercise analgesic response. These results support the prediction that the analgesic effect of exercise is not limited to controlled experimental conditions, but generalizes to naturally occurring situations.
本研究旨在调查自由运动训练后是否会出现运动后镇痛。17名男性参与者均有规律地进行锻炼。在运动环境（学生体育馆）中，他们进行20分钟的自选运动，而在中性环境（实验室）中，他们安静休息20分钟。通过总压力装置诱发疼痛。在运动和中性环境中，疼痛阈值和疼痛耐受度均每隔20分钟测量一次，共测量两次。运动环境中的疼痛阈值保持稳定。20分钟的运动训练后，疼痛耐受度显著提高，表明存在运动后镇痛反应。这些结果支持了以下预测：运动的镇痛效果不仅限于对照实验条件，还可推广到自然发生的情况。
