Resistance exercise has now been recommended as adjunct component of aerobic exercise on physical training program directed to the treatment and control of hypertension (HBP). However, it has not been widely incorporated yet into clinical practice, possibly by the scarcity of available evidence regarding the safe limits of the acute pressure response in this modality.
To investigate the acute effect of progressive resistance exercise of different body segments, the pressure response of patients with controled hypertension (HBP).
Twenty-five patients (14 women) with controled hypertension with medication (64.5 ± 10.8 years old) and sedentary, had three visits to a randomic progressive resistance exercise session, in the following muscle groups: femoral quadriceps, latissimus dorsi and brachial biceps. Blood pressure measurements were obtained at all visits at rest, immediately after each series of exercise and after 5 minutes of recovery.
Immediately after acute resistance exercise, a significant increase in systolic blood pressures, without significant changes of diastolic pressure compared to pressure levels at rest for all muscle groups and for all intensities studied. Additionally, there was a greater tendency to elevation of systolic pressure when the femoral quadriceps muscle was exercised at high intensity.
Resistance exercise in different body segments promoted similar increases and safe levels of systolic blood pressure, although with a tendency toward greater response of it when large muscle groups at high loads are exercised.
现在已经推荐抗阻运动作为有氧运动的辅助成分纳入到针对高血压(HBP)的治疗和控制的体能训练方案中。然而,由于关于这种运动方式的急性压力反应的安全极限的可用证据有限,它尚未广泛应用于临床实践中。
研究不同身体部位渐进性抗阻运动对血压得到控制的高血压(HBP)患者的血压急性反应的影响。
25 名患有高血压并服用药物的患者(64.5±10.8 岁,女性 14 名)和久坐不动的患者,在随机的渐进性抗阻运动中接受了三次不同的肌肉群(股四头肌、背阔肌和肱二头肌)的抗阻运动。所有运动期间均在休息、每组运动后立即和恢复 5 分钟后测量血压。
与休息时的血压水平相比,急性抗阻运动后即刻收缩压显著升高,而舒张压无显著变化,所有研究强度的所有肌肉群均如此。此外,当高强度锻炼股四头肌时,收缩压升高的趋势更大。
不同身体部位的抗阻运动可引起相似的收缩压升高和安全水平,尽管在高负荷下锻炼大肌群时,收缩压的反应更大。
