目的：应用运动后心率恢复（Heart Rate Recovery,HRR）与心率变异（Heart Rate Variability,HRV）预测心血管事件风险,探讨观看电视时间与心血管事件风险的关系。方法：采用横向研究方法,选取533名无规律性体育锻炼的健康成年女性为研究对象。抽取肘静脉血测定空腹血糖和血脂4项,问卷调查法获取受试者观看电视时间。记录分析安静时HRV,通过一次逐级递增负荷踏车运动测试,确定耗氧量峰值（Peak oxygen uptake,VO2peak）和运动后3min恢复心率（HRR和△HRR）。根据观看电视时间将受试者分成L（≤0.30h/d）、M（0.31~2.00h/d）和H（〉2.0h/d）3组,并比较3组成年女性的基本形态机能、HRR和HRV特征。结果：观看电视时间超过2h/d的成年女性,体重指数（BMI）、腰围、腰臀比、血压和甘油三酯水平相对较高,VO2peak相对较低,HRR延迟,HRV较小。受试者观看电视时间与年龄呈正相关（r=0.458,P〈0.05）,与△HRR1（r=-0.155,P〈0.05）,△HRR2（r=-0.141,P〈0.05）,△HRR3（r=-0.146,P〈0.05）,VO2peak（r=-0.100,P〈0.05）呈负相关关系。结论：长时间观看电视且HRR延迟的成年女性,心血管事件风险较高。相比HRV而言,HRR可能对心血管事件风险预测更为敏感。

Objective： Heart rate recovery and heart rate variability are valuable predictors for cardiovascular event risk. The aim of this study was to ascertain the relationship between television time and cardiovascular risk. Method： A total of 533 healthy female adult were enrolled in the study. They were not participated in regular physical exercise in the past. Cubital vein blood was obtained for determination of blood glucose and lipid profile. Television time was ob- tained by a questionnaire. Resting HRV data was collected and analysis. All subjects underwent a progressive cycle test for determining peak oxygen uptake （VO2 peak） and heart rate recover- y at 1,2 and 3 min （HRR and AHRR）. Subjects were divided into L group （≤0. 30 h/ day） ,M group （0.31-2.00 h/day） and H group （〉2.0 h/day） according television time. The anthropometrics, HRR and HRV were compared between groups. Result：The female a- dults with television time above 2 h/day had higher BMI, waist circumference, waist-to-hip ra- tio, blood pressure and triglyceride level, lower VO2 peak and HRV, slower HRR. Television time was positive correlated with subjects age （r = 0.458, P〈0.05 ）, and negative correlated withiHRR1 （r=-0.155,P〈0.05）,AHRR2（r=-0. 141,P〈0. 05）,AHRR3（r= - 0.146, P 〈0. 05 ）, and VO2 peak （ r = - 0. 100, P 〈 0. 05 ）. Conclusion： Female adults with a longer television time and slower HRR, had higher risk of cardiovascular event. Com- pared with HRV, HRR would be more sensitive to predict the cardiac event.
