Physical exercise is a strong physiological and mechanical stimulus that elicits various bodily sensations. They shape the emotional experience and contribute to the psychological benefits of exercise. Despite the centrality of subjective sensations stemming from altering bodily states during physical exercise, there is a paucity of data on bodily experiences and sensations evoked by physical exercise. Here, we mapped bodily sensations evoked by exercise in two studies. In the first proof-of-concept study, we asked participants (n = 305; 143 females) to imagine undergoing exercise training and report the expected bodily sensations. In the second field study, we mapped participants' (n = 133; 105 females) emotions and bodily sensations before and after actual exercise sessions. Both studies utilised visual analogue scales for sensation rating and a topographical self-report tool for mapping bodily sensations: participants were asked to colour on a human body silhouette all the bodily regions where each specified sensation (e.g. "Energized") was felt. The findings revealed a wide array of exercise-induced bodily sensations with mostly distinct topographies, that were consistent across individuals. The field experiment confirmed that bodily sensations of activeness and exhaustion intensified following exercise in topographically specific manner, and that the experience of exhaustion in the body mapping was linearly associated with physiological (heart rate) and subjective (rating of perceived exertion) indices of exertion. Altogether, these results show that different exercise-induced sensations have distinct bodily topographies and suggest that body sensation mapping might provide a novel approach for measuring exercise-induced emotional experiences and aid in planning exercise and recovery schedules.
体育锻炼是一种强烈的生理和机械刺激，会引发各种身体感觉。它们塑造了情感体验，并有助于锻炼带来的心理益处。尽管体育锻炼过程中身体状态改变所产生的主观感觉至关重要，但关于体育锻炼引发的身体体验和感觉的数据却很匮乏。在此，我们在两项研究中描绘了锻炼引发的身体感觉。在第一项概念验证研究中，我们要求参与者（n = 305；143名女性）想象进行锻炼训练并报告预期的身体感觉。在第二项实地研究中，我们描绘了参与者（n = 133；105名女性）在实际锻炼前后的情绪和身体感觉。两项研究均使用视觉模拟量表进行感觉评分，并使用一种地形学自我报告工具来描绘身体感觉：要求参与者在人体轮廓图上为每种特定感觉（例如“精力充沛”）所感受到的所有身体区域上色。研究结果揭示了一系列锻炼引发的身体感觉，其地形大多各不相同，且个体间具有一致性。实地实验证实，活跃和疲惫的身体感觉在锻炼后以地形学上特定的方式增强，并且身体映射中的疲惫体验与生理（心率）和主观（感知运动用力评分）运动指标呈线性相关。总之，这些结果表明不同的锻炼引发感觉具有不同的身体地形，并表明身体感觉映射可能为测量锻炼引发的情感体验提供一种新方法，并有助于规划锻炼和恢复计划。
