| 摘要： |
| 目的：探究肥胖对血流动力学运动反应的影响，为肥胖相关心血管疾病的运动监控提供理论支持。方法：体重正常和肥胖男青年各10名，连续采集运动前后系统血流动力学指标（BP、HR、DP、SI、CI）和指端血流动力学参数（K′、VDF、VCF、PCII、VCTI）进行分析。结果：肥胖青年男性运动前的SBP、rHR和rPCII明显高于体重正常者；运动后eSI和eCI明显低于体重正常者；运动后eK′和ePCII明显高于体重正常者。相关分析表明，Fat%与rSBP、rHR、eSI、eCI、eK′和ePCII密切相关；系统血流动力学指标和指端血流动力学指标间的偏相关分析表明，rPCII与rHR、eK′和eCI、ePCII和eCI密切相关。结论：肥胖会引发青年男性运动前后指端血流动力学改变。运动前后系统血流动力学和指端血流动力学指标间具有相关性，提示指端容积血流脉搏波参数有望成为运动心血管机能监测的新指标。 |

| Abstract: |
| Objective: To examine the influence of obese on the hemodynamic responses to graded exercises. Method: To record and analyse the system and fingertip hemodynamic exercise responses parameters before and after graded exercises. Result: The parameters of rSBP、rHR and rPCII of obese group(OB) were significantly higher than that of normal weight group(NW) in pre-exercises stage;eSI and eCI of OR were significantly lower than that of NW, ePCII and eK′ of OR were significantly higher than that of NW in post-exerxcise stage. Partial correlation analysis showed that Fat% with system and fingertip hemodynamic parameters existed significant correlations, rPCII and rHR、eK′ were significantly correlated with eCI、ePCII and eCI. Conclusion: Before and affer exercise system and fingertip hemodynamic parameters of obese young men existed significant correlations. Photoplethysmographic parameters seem to be promising for exercises cardiovascular monitoring in the future. |
