Whole-body vibration (WBV) exercises have recently been introduced as a nonpharmacological therapeutic strategy for sarcopenic older people. The present study aimed to evaluate the effect of WBV exercise on hemodynamic parameters in sarcopenic older people. Forty older people, divided into groups of nonsarcopenic (NSG = 20) and sarcopenic (SG = 20), participated in the study and were cross randomized into two interventions of eight sets of 40 s each, these being squatting with WBV and squatting without WBV. Heart rate (HR), peak heart rate (peak HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), double product (DP), mean arterial pressure (MAP), and subjective perception of effort (SPE), were assessed at baseline, during, and after a single WBV session. The HR, peak HR, and DP variables were similar at baseline between groups. WBV exercise increased all the hemodynamic parameters both during and immediately after the intervention, in both groups (SG and NSG). The MAP values were similar at baseline between groups; however, in the NSG there was a significant increase during and immediately after the squatting with WBV intervention ( < 0.05). The HR behavior, in both groups, showed that there was an increase in HR after the first set of exercises with vibration and this increase was maintained until the final set. The absence of adverse effects of WBV exercise on the cardiovascular system and fatigue suggests this exercise modality is adequate and safe for sarcopenic older people.
全身振动（WBV）练习最近被引入作为治疗肌少症老年人的非药物治疗策略。本研究旨在评估 WBV 练习对肌少症老年人血流动力学参数的影响。40 名老年人分为非肌少症（NSG = 20）和肌少症（SG = 20）两组，进行了交叉随机分组，分别接受 8 组每组 40 秒的深蹲和 WBV 深蹲两种干预措施。在基线、干预期间和单次 WBV 后评估心率（HR）、峰值心率（peak HR）、收缩压（SBP）、舒张压（DBP）、双乘积（DP）、平均动脉压（MAP）和主观用力感知（SPE）。在基线时，两组之间的 HR、peak HR 和 DP 变量相似。WBV 运动在干预期间和干预后立即增加了所有血流动力学参数，在 SG 和 NSG 两组中均如此。在基线时，两组之间的 MAP 值相似；然而，在 NSG 中，在进行 WBV 深蹲干预时，MAP 值在期间和立即增加（<0.05）。在两组中，HR 行为均显示在第一组带有振动的练习后 HR 增加，这种增加一直持续到最后一组。WBV 运动对心血管系统和疲劳没有不良影响，这表明这种运动方式对于肌少症老年人是足够和安全的。
