to investigate the efficacy of addition of inspiratory muscle training (IMT) to the whole body vibration (WBV) on functional outcomes, physical performance, muscle strength and metabolism in pre-frail older women.
this study was a randomized double-blind trial. Forty-two older women aged 60-80 years who meet the Cardiovascular Health Study frailty criteria for pre-frailty were randomly allocated to IMT + WBV, IMTsham + WBV or Sham groups. IMT + WBV group received 12 weeks of both trainings, whereas IMTsham + WVB received 12 weeks of WBV alone. Sham group received 12 weeks of IMT with a low fixed load and were positioned at the vibratory platform without therapeutic effect. Participants were evaluated before and after the intervention for the following outcomes: 6-min walk test distance (6MWD), balance using Tinetti test, functional mobility using timed up and go test (TUG), handgrip strength (HGS) and peripheral muscle metabolism (glucose and lactate levels).
after the training, both groups IMT + WBV and IMTsham + WBV improved 6MWD [mean percentage changes = 20.31 (SD = 14.62) and 13.02 (SD = 12.14), respectively] compared with Sham [0.27 (SD = 6.51)], P <0.01. There was also a significant decrease of mean percentage changes on time of the TUG for IMT + WBV [-21.87 (SD = 7.87)] and IMTsham + WBV [-11.15 (SD = 13.64)] compared with Sham [-4.25 (SD = 13.25)], P <0.01. IMT + WBV group improved balance when compared with IMTsham + WBV and Sham groups (P <0.05 and < 0.01, respectively). HGS and levels of lactate and glucose were similar between groups.
the addition of IMT to the WBV was effective to improve functionality, balance and physical performance in pre-frail older women.
研究吸气肌训练（IMT）联合全身振动（WBV）对衰弱前期老年女性的功能结局、身体表现、肌肉力量和代谢的疗效。
这是一项随机双盲试验。42 名年龄在 60-80 岁之间、符合心血管健康研究衰弱前期衰弱标准的老年女性被随机分配到 IMT+WBV、IMTsham+WBV 或 Sham 组。IMT+WBV 组接受 12 周的两种训练，而 IMTsham+WVB 组接受 12 周的单独 WBV 治疗。Sham 组接受 12 周的低固定负荷 IMT，并置于无治疗效果的振动平台上。在干预前后，参与者评估以下结果：6 分钟步行测试距离（6MWD）、Tinetti 测试平衡、计时起立行走测试（TUG）功能移动性、手握力（HGS）和外周肌肉代谢（葡萄糖和乳酸水平）。
在训练后，IMT+WBV 和 IMTsham+WBV 两组的 6MWD 均有改善[平均百分比变化分别为 20.31%（SD=14.62%）和 13.02%（SD=12.14%）]，而 Sham 组为 0.27%（SD=6.51%），P<0.01。IMT+WBV 和 IMTsham+WBV 两组 TUG 时间的平均百分比变化也显著降低，与 Sham 组相比分别为-21.87%（SD=7.87%）和-11.15%（SD=13.64%），P<0.01。与 IMTsham+WBV 和 Sham 组相比，IMT+WBV 组的平衡能力得到改善（P<0.05 和 P<0.01）。HGS 以及乳酸和葡萄糖水平在各组之间相似。
在衰弱前期老年女性中，IMT 联合 WBV 可有效改善功能、平衡和身体表现。
