Broad claims have been made regarding the health benefits of physical activity. In analyzing the data on which these claims are based, including those on the risks of exercise, 5 of 13 proposed health benefits were found to have strong support in the literature. For the remainder the evidence is less conclusive or equivocal. Data regarding the risks of exercise are similarly varied. Proponents of physical activity should evaluate the documentation of its benefits and risks so as not to dilute the power of their remedy with unsubstantiated claims.
关于体育活动对健康的益处,人们提出了广泛的主张。在分析这些主张所依据的数据时,包括那些关于运动风险的数据,发现13项提出的健康益处中有5项在文献中有强有力的支持。对于其余的益处,证据则不太确凿或模棱两可。关于运动风险的数据同样各不相同。体育活动的支持者应该评估其益处和风险的文献记录,以免用未经证实的主张削弱其疗法的效力。
