To investigate the effect of combined aerobic and resistance training (CART) on heart rate variability in sedentary, hypertensive women.
A total of twenty-eight hypertensive (Stage 1 and 2) sedentary women (Age 40.54 ± 4.2 yrs; Height 155.14 ± 5.4 cm; Weight 70.96 ± 10.2 kg; BMI 29.6 ± 4.4; Duration of HTN: 6.43 ± 2.5 yrs) were recruited for the study.
Participants were randomly assigned to either the CART group that performed combined aerobic and resistance exercise of moderate intensity [aerobic exercise 50-80% of HR (maximum heart rate) and resistance exercises at 50-80% of 1 Repetition Maximum (RM)], 5 times/week for 4 weeks, or to the control group that followed conventional treatment without any supervised exercise intervention.
Resting blood pressure was measured and standard heart rate variability (HRV) indices were calculated using time domain (SDNN, pNN50, RMSSD) and frequency domain (LFnu, HFnu, LF/HF and TP) analysis.
CART group demonstrated an increase in HFnu, TP, SDNN, and RMSSD, (p < 0.05) along with a significant decrease in LFnu, LF/HF ratio, systolic blood pressure, and diastolic blood pressure (p < 0.05).
CART showed significant improvement in HRV parameters indicating vagal dominance in middle-aged hypertensive women. Therefore, exercise training in combined form (aerobic and resistance) may be incorporated in the management programs of the patients suffering from hypertension in order to augment improvement in their cardiac autonomic control.
探讨有氧与抗阻联合训练（CART）对久坐不动的高血压女性心率变异性的影响。
共招募了28名久坐不动的高血压（1期和2期）女性（年龄40.54±4.2岁；身高155.14±5.4厘米；体重70.96±10.2千克；体重指数29.6±4.4；高血压病程：6.43±2.5年）参与本研究。
参与者被随机分配至CART组，该组进行中等强度的有氧与抗阻联合运动[有氧运动为心率（最大心率）的50 - 80%，抗阻运动为1次重复最大值（RM）的50 - 80%]，每周5次，共4周；或分配至对照组，该组接受常规治疗，无任何监督运动干预。
测量静息血压，并使用时域（SDNN、pNN50、RMSSD）和频域（LFnu、HFnu、LF/HF和TP）分析计算标准心率变异性（HRV）指标。
CART组的HFnu、TP、SDNN和RMSSD增加（p<0.05），同时LFnu、LF/HF比值、收缩压和舒张压显著降低（p<0.05）。
CART显示出HRV参数的显著改善，表明中年高血压女性存在迷走神经优势。因此，联合形式（有氧和抗阻）的运动训练可纳入高血压患者的管理方案中，以增强其心脏自主控制的改善。
