目的 了解中国与东南亚国家男性大学生体力活动水平及体成分的差异，并探讨体力活动水平与体成分的相关性。 方法 随机选取广西某高校442名男性大学生，其中中国大学生294名，东南亚国家大学生148名，采用国际体力学问卷调查体力活动水平，人体体成分分析仪测量体成分，采用SPSS 16.0统计学软件进行分析。结果 除中等强度体力活动水平外（P>0.05），中国男性大学生的步行活动水平、高强度体力活动水平、总体力活动水平均高于东南亚国家男性大学生（P值均<0.05)；东南亚国家男性大学生与中国男性大学生的体成分含量存在明显差异；Pearson 相关分析，步行体力活动水平与体重、脂肪量、肌肉量、推定骨量及浮肿指数等成负相关关系，高强度体力活动水平与去脂体重、肌肉量、推定骨量等成正相关关系，与脂肪量及水肿指数等成负相关关系，而中等强度体力活动水平仅与身高成负相关关系。 结论 中国男性大学生与东南亚男性大学生的体力活动水平和体成分含量均存在明显的差异,可能与基因、种族、饮食、等多因素相关；高强度体力活动水平更有利于保持体质健康。

Objective To study the level of physical activity and body composition of male college students in China and Southeast Asian countries, and to explore the correlation between physical activity level and body composition. Methods A total of 442 male college students were randomly selected in a college in Guangxi, of which 294 Chinese college students, 148 college students in Southeast Asian countries.Physical activity level was investigated using the international physical questionnaire, and body composition was measured by body composition analyzer. Statistical analysis was performed using SPSS 16.0 software. Results In addition to moderate intensity physical activity level (P>0.05),walking activity level, the high intensity physical activity level and total physical activity of Chinese male college students were higher than that of South East Asian countries (all P<0.05).Pearson correlation analysis showed that the level of walking physical activity was negatively correlated with body weight, fat, muscle volume, presumed bone mass and swelling index.High intensity physical activity level and body fat, muscle mass, bone mass was positively related presumption, and has a negative correlation with fat content and swelling index.The level of middle strength physical activity was only negatively correlated with height. Conclusion There are significant differences in physical activity level and body composition between male college students and Southeast Asian male college students. These might may be related to genes, ethnic groups, diet and other factors. It is suggested that high intensity physical activity levels are more conducive to maintaining physical health.
