This study aimed to investigate the effect and carry-over effect of arm swing exercise (ASE) training on cardiac autonomic modulation, cardiovascular risk factors, and blood electrolytes in older persons with prehypertension.
Subjects were 50 individuals with prehypertension (aged 66.90 ± 5.50 yr, body mass index 23.84 ± 3.65 kg/m). They were randomly assigned into ASE group and control group. Subjects in the ASE group underwent an ASE training program for 3 months at a frequency of 30 min/day, 3 days/week. Subjects in the control group maintained their daily routine activities minus regular exercise. Blood pressure, heart rate variability (HRV), cardiovascular risk factors including blood glucose, lipid profile, high-sensitive C-reactive protein (hsCRP), and electrolytes were evaluated on 3 occasions: before and after the 3-month intervention, and 1 month after intervention ended.
Following the 3-month intervention, systolic blood pressure (SBP) and serum hsCRP concentration were significantly lower, while serum high-density lipoprotein (HDL)-cholesterol, potassium (K), magnesium (Mg) concentrations, standard deviation of normal R-R intervals (RMSSD) and high frequency (HF) power values were higher in the ASE group when compared with the control group (p < 0.05). At the 1-month follow-up interval, SBP and serum hsCRP concentration remained lower while serum HDL-cholesterol and K concentrations remained higher in the ASE group as compared to the control group (p < 0.05).
ASE training decreased SBP and serum hsCRP concentration, increased serum HDL-cholesterol, K, and Mg concentrations and increased RMSSD and HF power values in older persons with prehypertension. In addition, there were carry-over effects of ASE training i.e. decreased SBP and serum hsCRP concentration as well as increased serum HDL-cholesterol and K concentrations.
本研究旨在探讨摆臂运动（ASE）训练对高血压前期老年人心脏自主神经调节、心血管危险因素及血液电解质的影响及延续效应。
研究对象为50名高血压前期患者（年龄66.90±5.50岁，体重指数23.84±3.65kg/m）。他们被随机分为ASE组和对照组。ASE组的受试者进行了为期3个月的ASE训练计划，每天训练30分钟，每周3天。对照组的受试者保持日常活动，但不进行常规运动。在三个时间点评估血压、心率变异性（HRV）、心血管危险因素（包括血糖、血脂谱、高敏C反应蛋白（hsCRP））和电解质：3个月干预前后，以及干预结束后1个月。
经过3个月的干预，与对照组相比，ASE组的收缩压（SBP）和血清hsCRP浓度显著降低，而血清高密度脂蛋白（HDL）胆固醇、钾（K）、镁（Mg）浓度、正常R-R间期标准差（RMSSD）和高频（HF）功率值更高（p<0.05）。在1个月的随访期，与对照组相比，ASE组的SBP和血清hsCRP浓度仍然较低，而血清HDL胆固醇和K浓度仍然较高（p<0.05）。
ASE训练可降低高血压前期老年人的SBP和血清hsCRP浓度，增加血清HDL胆固醇、K和Mg浓度，并增加RMSSD和HF功率值。此外，ASE训练存在延续效应，即降低SBP和血清hsCRP浓度以及增加血清HDL胆固醇和K浓度。
