中文摘要：
目的：通过对246名40～49岁健康中年男性进行体力活动问卷调查和心肺耐力测试，分析二者与心血管疾病相关风险因素之间的相关性。结果：1）随着体力活动总消耗量水平增加，心血管疾病相关风险因素并未出现改善趋势，方差分析无显著性差异，二者之间不存在相关性；2）随着心肺耐力水平等级的提高，心血管相关风险因素出现明显的改善；二者之间呈显著性相关。结论：1）体力活动消耗量水平未引起心血管疾病相关风险因素的改善，并不能作为心血管疾病风险因素的评价指标；2）随着心肺耐力水平的改善，心血管相关的风险因素出现明显改善，心肺耐力要比体力活动更能作为心血管疾病风险因素的评价指标。
英文摘要：
Objective： through International Physical Activity Questionnaire （IPAQ） and cardiorespiratory fitness （CRF） ergometer exercise test for 246 healthy adult men aged 40 49 years, this study analyzes the associations of PA and CRF with cardiovascular risk factors. Results ： 1 ） with the rise on PA, there would be no improvement in cardiovascular risk factors, no significant difference in variance analysis and no correlation between the two fac tors ; 2） With the development of CRF, there is notability descent of cardiovascular risk factors, cardiovascular re lated risk factors have been significantly improved and the two factors are significantly correlated. Conclusion ： 1 ） PA does not improve the cardiovascular related risk factors and can not be regarded as the evaluation indicator of the risk factors. 2） With the improvement of CRF, cardiovascular related risk factors are significantly improved, and CRF can be regarded as the evaluation index for predicting cardiovascular risk factors rather than PA.
