摘要
目的:利用通气阈确定男性肥胖高血压患者运动强度。方法:分别选取41例男性肥胖高血压者为实验组,41例男性无肥胖、无高血压者为对照组。在两组达到通气阈时,比较吸氧量、功率、心率、心率差、%最高心率、%心率贮备、主观劳累强度、收缩压、平均动脉压、舒张压,从而确定实验组的适宜运动强度。另外,实验组进行该强度下的运动处方训练。结果:在通气阈时,实验组的耗氧量、功率、心率贮备、心率差明显低于对照组(P<0.05),而收缩压、舒张压及平均动脉压高于对照组(P<0.05);主观劳累强度两组无差异。经过一年该强度的训练,男性肥胖高血压患者中身体成分及安静时血压都有显著性改善。结论:对于男性肥胖高血压患者,可以采用通气阈确定其适宜运动强度,即运动强度是60%最高心率、30%心率贮备和主观劳累强度12。
Objective:To evaluate exercises intensity for hypertensive obese men by ventilatory threshold. Method: Forty one obese males with hypertension were enrolled and 41 sex matched subjects without obese and hypertension were control subjects. Ventilatory threshold (VT) was defined during exercises test, then suitable intensity was determined basing on VT and exercises prescription was drawn up . Testing index: height, body weight, BMI, body fat percentage, waist circumference, blood pressure, hip circumference, waist hip ratio, rates of oxygen consumption (VO2),work rate (WR),heart rate(HR),%HRmax,%HR reserve and rate of perceived exertion (RPE) were measured at VT. Result: At AT, VO2 and WR of obese subjects with hypertension were significant lower than control subjects.% HR reserve was also significantly lower than control subjects, while there was no difference in %HRmax. RPE was also similar among the 2 groups. After one year of prescribed low-grade exercises and follow up study,not only body composition but also blood pressure at rest improved in obese hypertension subjects. Conclusion: Exercises extensity of 60%HRmax,30%HR reserve and RPE 12 is recommended in obese subjects with hypertension.
