有氧联合抗阻运动对老年脑梗死患者的影响

Influence of aerobic and resistance exercises on elderly patients with cerebral infarction

摘要:

目的探讨有氧联合抗阻运动对老年脑梗死患者的影响。方法选取南阳市中心医院收治的脑梗死老年患者80 例作为研究对象，随机分为对照组和研究组各40 例。对照组采用有氧运动，研究组在对照组基础上联合抗阻运动。观察两组患者自主神经功能情况。结果两组患者心率变异性指标总功率（TP）、高频功率（HF）及归一化高频功率（HFn）均较干预前升高，研究组高于对照组；低频功率（LF）、归一化低频功率（LFn）及LF/HF 均较干预前下降，研究组低于对照组；两组患者血压变异性指标TP、HF、HFn、LF 及LFn 均较干预前降 低，研究组低于对照组；干预后研究组低频压力反射敏感性高于对照组。结论有氧联合抗阻运动可有效调节老年脑梗死患者交感神经以及迷走神经张力，使心血管自主神经功能趋于平衡。

Abstract:

Objective To explore the influence of aerobic and resistance exercises on elderly patients with cerebral infarction. Methods Eighty cases of elderly patients with cerebral infarction treated in our hospital were selected as the study objects, and randomly divided into study group and control group with 40 cases in each group. The patients of the control group did aerobic exercise, and those of the study group did aerobic and resistance exercises. Autonomic nervous function was observed in the two groups. Results Some of the heart rate variability (HRV) indexes including total power (TP), high-frequency power (HF), normalized highfrequency power (HFn) after intervention were higher than those before intervention in the two groups (p <0.05), and the above indexes of the study group were higher than those of the control group (p < 0.05).However, low-frequency power (LF), normalized low-frequency power (LFn), and LF/HF were decreased after intervention (p < 0.05), and they were lower in the study group than in the control group (p < 0.05). Blood pressure variability (BPV) indexes such as TP, HF, HFn, LF and LFn decreased after intervention in both groups (p < 0.05), and the above indexes of the study group were lower than those of the control group (p <0.05). After intervation, low-frequency baroreflex sensitivity (BRS LF) in the study group was higher than that in the control group (p < 0.05). Conclusions Aerobic and resistance exercises can adjust tension of sympathetic and vagus nerves in the elderly patients with cerebral infarction, and balance cardiovascular autonomic function.
