Objective · To explore the effects of "brisk walking" on blood pressure, body mass index (BMI), and autonomic nerve activity of male elderly with hypertension in community-based health centers in Shanghai. Methods · A total of 630 elderly men received "brisk walking" treatment (>10000 steps/d) voluntarily, who were selected from six community-based health centers in Pudong New Area of Shanghai. Among them, 210 people stick to training for 12 weeks. According to whether suffering from hypertension, the people were assigned to hypertension intervened group (intervention group, n=110) and normal intervened group (control group 1, n=100). Blood pressure, BMI, heart rate and autonomic nerve activity before and after the training were compared. Results · After 12 weeks of training, systolic blood pressure (SBP), diastolic blood pressure (DBP) and sympathetic nerve activity of intervention group were significantly lower than those before the training (P<0.05). SBP was also significantly lower than control group 2 (P<0.05). However, heart rate, BMI, parasympathetic nerve activity and baroreceptor reflex sensitivity did not change significantly after the training (P>0.05). Conclusion · "Brisk walking" treatment lasting for 12 weeks can decrease blood pressure and sympathetic nerve activity in elderly men with hypertension. It is worthy to be popularized in the community.%目的 · 分析"健步行"运动处方对上海社区老年男性高血压人群的血压、体质量指数(BMI)、自主神经活动等的干预效果.方法 · 在上海浦东新区社区医院630名自愿参与"健步行"运动(>10000步/d)的老年男性中,选取坚持完成12周训练者210名,根据是否患有高血压分为高血压干预组(干预组,n=110)和正常干预对照组(对照组1,n=100).再选取200名高血压老年男性患者,进行常规治疗,不进行运动干预(对照组2).比较各组训练前后血压、BMI、心率和自主神经活动的变化.结果 · 干预组经12周训练后收缩压(SBP)、舒张压(DBP)和交感神经活动较训练前均显著降低(均P<0.05),SBP显著低于对照组2(P<0.05),而心率、BMI、副交感神经活动和压力感受器反射敏感性训练前后差异均无统计学意义(均P>0.05).结论 · 对高血压老年男性患者实施12周的"健步行"运动处方,可以降低血压和交感神经活动,值得在社区中普及推广.
