摘要

背景:心血管疾病和肥胖相关的合并症是代谢减肥手术(MBS)解决的关键因素。尽管高强度间歇训练(HIIT)已被证明在健康人群中有效,但关于MBS后HIIT和坚持HIIT的证据有限。本研究旨在验证MBS后HIIT的可行性及心肺效果。方法:201例接受MBS的患者在德国一所大学医学中心接受为期四周的训练方案,分为3个训练组(B-D),包括针对肥胖患者设计的不同自行车HIIT方案和一个对照组(a)。在训练前和训练后进行测量,测量VO2max、最大血乳酸、最大阻力、在测力仪上花费的时间和心率。结果:与对照组相比,训练组在100 W时心率降低,最大血乳酸增加,最大阻力增加(Δ 9,67 BPM; Δ 1.02 mmol/l; Δ 12 W),均显示出4周训练的显著效果。结论:HIIT自行车训练对mbs后患者可能非常有效,但依从性极低。虽然这项研究显示了有希望的结果,但如果不首先改善依从性和广泛的训练方法,就不能期望对大患者群体产生影响。研究注册:德国临床试验注册中心(DRKS)试验注册号为DRKS00024939,日期为20/09/2021。

Optimizing cardiorespiratory fitness after bariatric surgery - highly effective with very low adherence: HIT BAR randomized controlled trial.

Background: Cardiovascular disease and obesity-related comorbidities are key factors addressed by metabolic-bariatric surgery (MBS). Although High intensity interval training (HIIT) has been proven effective in healthy cohorts, limited evidence exists regarding HIIT and adherence towards HIIT after MBS. This study aims to test feasibility and cardiorespiratory effect of HIIT after MBS.

Methods: 201 patients undergoing MBS were included in a four-week training protocol with 3 training groups (B-D) including different HIIT protocols on a bicycle designed for patients with obesity and one control group (A) at a university medical center in Germany. Ergometry with estimated VO2max, maximum blood lactate, maximum resistance, time spent on ergometer, and heart rate were performed prior to and after 4 weeks of training.

Results: A significant effect of the four-week training could be shown through reduction of heart rate at 100 W, increase of maximum blood lactate, and maximum resistance when comparing the training groups to the control group (Δ 9,67 BPM; Δ 1.02 mmol/l; Δ 12 W respectively, all p < 0.05) However, adherence of the recruited patient group was very low, shown by a notably high drop-out rate of 78.1% overall (44 patients completed training). The majority of patients dropped out prior to the first training session.

Conclusions: HIIT bicycle training in post-MBS patients is possibly very effective, however, adherence is extremely low. Although this study shows promising results, an effect on large patient groups cannot be expected if improvement of adherence and a wide range of training methods are not addressed first.
