【摘要】：目的:探讨长期有氧训练对老年男性原发性高血压患者血流动力学、运动能力和认知功能的影响,以期为此类人群制定有针对性的运动处方提供理论支持。方法:92名老年男性原发性高血压患者(年龄:60~70岁)按照随机原则分为安静对照组(n=46)和有氧训练组(n=46),安静对照组保持原有生活习惯,有氧训练组进行3个月有氧训练干预。分别于实验前后测定两组受试者的安静心率和血压;利用递增负荷运动实验测定最大摄氧量(V·O2max)、力竭时间和力竭距离并描计运动过程中的心率曲线、血压曲线和主观疲劳感觉(RPE)曲线;利用软件测试受试者基本认知能力(包括知觉速度、心算效率、空间表象、工作记忆、记忆再认和总成绩共6个得分)。结果:安静对照组各指标均无显著性变化(P0.05)。有氧训练组进行运动后安静心率、收缩压和舒张压下降(P0.05);递增负荷运动试验中,V·O2max、力竭时间和力竭距离升高(P0.05),心率曲线、血压曲线和RPE曲线右移(P0.05);认知能力测验中,知觉速度、工作记忆和总成绩显著提高(P0.05)。结论:长期有氧训练能够改善老年男性高血压患者血流动力学异常,提高运动能力和认知功能中的短暂信息处理能力。
[Abstract]:Objective: to investigate the effects of long-term aerobic training on hemodynamics, motor ability and cognitive function in elderly male patients with essential hypertension. Methods: 92 elderly male patients with essential hypertension (age: 60 ~ 70 years old) were randomly divided into two groups: quiet control group (n = 46) and aerobic training group (n = 46). Aerobic training group 3 months aerobic training intervention. The resting heart rate and blood pressure of the two groups were measured before and after the experiment. The maximal oxygen uptake (V O2max), exhaustion time and exhaustion distance were measured by incremental load exercise experiment. The heart rate curve, blood pressure curve and (RPE) curve of subjective fatigue sensation were plotted during exercise. The basic cognitive abilities of the subjects were tested by software (including 6 scores: perceptual speed, mental arithmetic efficiency, spatial representation, working memory, memory recognition and total score). Results: there was no significant change in every index in quiet control group (P0.05). The rest heart rate, systolic blood pressure and diastolic pressure in aerobic training group decreased after exercise (P0.05). In incremental load exercise test, VO _ 2max, exhaustion time and exhaustion distance increased (P0.05), heart rate curve, blood pressure curve and RPE curve shifted to the right (P0.05). In the cognitive ability test, perceptual speed, working memory and total scores were significantly improved (P0.05). Conclusion: long-term aerobic training can improve hemodynamic abnormality, motor ability and transient information processing ability in elderly male patients with hypertension.
