The influence of physical exercise on the parameters of the cardiovascular system of elderly persons has not been sufficiently investigated yet. The aim of the study was to assess the influence of regular 6-week physical exercise using the Nordic walking (NW) method in a group of elderly persons on their physical performance and regulation of selected parameters assessing the cardiovascular system.
Fifty patients over 65 years of age participated in the study. The study encompassed: medical interview, physical examination, resting ECG, spiroergometry examination, 6MWT (6-minute walk test) and 24-hour ambulatory blood pressure monitoring (ABPM). During the exercise programme, the pulse was monitored using pulsometers. After the completion of the training, check-up tests assessing the same parameters were performed. The control group consisted of 18 persons over 65 years of age with similar cardiovascular problems.
In the test group, duration of the physical effort increased by 1.02 min (p = 0.0001), the maximum load increased by 10.68 W (p = 0.0001), values of VO2max by 2.10 (p = 0.0218), distance improved in 6MWT by 75.04 m (p = 0.00001), systolic blood pressure decreased by 5.50 mm Hg (p = 0.035) and diastolic blood pressure by 3.50 mm Hg (p = 0.054) as compared to the control group.
Systematic NW physical exercise limited by the pulse had a beneficial effect on the physical performance of elderly persons as assessed with main parameters. A short 6-week programme of endurance exercises had a hypotensive effect in elderly persons over 65 years of age.
运动对老年人心血管系统参数的影响尚未得到充分研究。本研究的目的是评估使用北欧行走(NW)方法对老年人进行为期 6 周的有规律的身体锻炼对其身体机能和选择的心血管系统参数调节的影响。
50 名 65 岁以上的患者参加了这项研究。研究包括:医学访谈、体检、静息心电图、测功仪检查、6MWT(6 分钟步行试验)和 24 小时动态血压监测(ABPM)。在运动过程中,使用脉搏计监测脉搏。在完成训练后,对评估相同参数的检查进行了检查。对照组由 18 名 65 岁以上有类似心血管问题的人组成。
在实验组中,体力活动时间延长了 1.02 分钟(p = 0.0001),最大负荷增加了 10.68 瓦(p = 0.0001),VO2max 值增加了 2.10(p = 0.0218),6MWT 中距离增加了 75.04 米(p = 0.00001),收缩压降低了 5.50 毫米汞柱(p = 0.035),舒张压降低了 3.50 毫米汞柱(p = 0.054),与对照组相比。
受脉搏限制的系统 NW 体育锻炼对老年人的身体表现有有益的影响,主要参数评估。为期 6 周的耐力运动方案对 65 岁以上的老年人具有降压作用。
