To assess the impact of bariatric surgery and an added supervised exercise training programme on heart rate variability (HRV) in patients with severe obesity.
Fifty-nine patients who underwent bariatric surgery were randomised in the post-operative period to a 12-week supervised exercise training programme (moderate intensity combination aerobic/resistance exercise training programme) or a control group. Indices of HRV including time-domain, spectral-domain, and nonlinear parameters were measured preoperatively, and at 3, 6, and 12 months.
After the surgical procedure, both groups improved anthropometric parameters. Type 2 diabetes, hypertension, and dyslipidemia resolutions were similar between groups. Total body weight loss at 6 and 12 months were also comparable between groups (6 months: 28 ± 6 vs. 30 ± 6%; 12 months: 38 ± 9 vs. 38 ± 10%; control vs. intervention group respectively). Bariatric surgery improved HRV parameters at 12 months compared to the pre-operative values in the intervention group: standard deviation of R-R interval (SDNN) (156.0 ± 46.4 vs. 122.6 ± 33.1 ms), low frequency (LF) (6.3 ± 0.8 vs. 5.8 ± 0.7 ms), and high frequency (HF) (5.1 ± 0.8 vs. 4.7 ± 0.9 ms) (all <0.001). For the control patients, similar improvements in SDNN (150.0 ± 39.4 vs. 118.8 ± 20.1 ms), LF (6.1 ± 0.9 vs. 5.7 ± 0.8 ms), and HF (5.0 ± 0.9 vs. 4.7 ± 0.9 ms) were obtained (all <0.001). However, there was no add-on impact of the supervised exercise training programme on HRV after 12 months (>0.05 for all HRV parameters).
Bariatric surgery is associated with an improvement in HRV. A supervised exercise training programme in the post-operative period did not modulate further the benefits of bariatric surgery regarding HRV parameters.
评估减重手术和附加的监督运动训练方案对严重肥胖患者心率变异性（HRV）的影响。
59 名接受减重手术的患者在术后随机分为 12 周监督运动训练组（中等强度有氧/抗阻运动训练方案）或对照组。术前和术后 3、6 和 12 个月测量 HRV 的时域、频域和非线性参数。
手术后，两组的人体测量参数均得到改善。两组之间的 2 型糖尿病、高血压和血脂异常的缓解情况相似。6 个月和 12 个月时两组的总体重减轻量也相当（6 个月：28±6%比 30±6%；12 个月：38±9%比 38±10%；对照组与干预组分别）。与术前相比，减重手术在 12 个月时改善了干预组的 HRV 参数：RR 间期标准差（SDNN）（156.0±46.4 比 122.6±33.1ms）、低频（LF）（6.3±0.8 比 5.8±0.7ms）和高频（HF）（5.1±0.8 比 4.7±0.9ms）（均<0.001）。对于对照组患者，SDNN（150.0±39.4 比 118.8±20.1ms）、LF（6.1±0.9 比 5.7±0.8ms）和 HF（5.0±0.9 比 4.7±0.9ms）也得到了类似的改善（均<0.001）。然而，监督运动训练方案在 12 个月后对 HRV 没有额外的影响（所有 HRV 参数均>0.05）。
减重手术与 HRV 的改善相关。术后监督运动训练方案并未进一步调节减重手术对 HRV 参数的益处。
