英国牛津大学研究人员对该校赛艇队队员进行研究后发现，他们在参加集体训练之后，抗疼痛能力明显增强。

牛津大学16日发布新闻公报说，12名赛艇队员参与了相关测试。他们被要求进行常规器械训练、两组6人对抗训练，以及没有任何队友的单独训练。随后通过测试他们对压力所致疼痛的忍耐程度发现，这些训练都会增加队员的抗疼痛能力，但与单独训练相比，集体训练的效果要明显得多。

研究人员说，以往研究显示运动会促使人体分泌具有麻醉作用的脑内啡，以帮助增强抗疼痛能力。此次研究结果说明，集体活动可能会使脑内啡分泌量增加，从而进一步增强人的抗疼痛能力。

相关报告发表在英国《生物学通信》杂志上。

Physical exercise is known to stimulate the release of endorphins, creating a mild sense of euphoria that has rewarding properties. Using pain tolerance (a conventional non-invasive assay for endorphin release), we show that synchronized training in a college rowing crew creates a heightened endorphin surge compared with a similar training regime carried out alone. This heightened effect from synchronized activity may explain the sense of euphoria experienced during other social activities (such as laughter, music-making and dancing) that are involved in social bonding in humans and possibly other vertebrates.
