To evaluate the acute and chronic effect of an exercise protocol of pelvic floor muscles (PFMs) contraction on the heart period (HP) and systolic arterial pressure (SAP) variabilities and baroreflex sensitivity (BRS) at rest in pregnant women; and to evaluate if this progressive exercise protocol was well-tolerated by the pregnant women studied.
We evaluated 48 women at 18 weeks of pregnancy by vaginal palpation, vaginal manometry, and cardiopulmonary exercise test. They were divided in control (CG; 31.75 ± 3.91 years) and training groups (TG; 30.71 ± 3.94 years). At 19 and 36 weeks of pregnancy, electrocardiogram and noninvasive peripheral SAP data were collected at rest before and after 10 PFM contractions. TG performed PFMT from the 20th to the 36th week. HP and SAP variabilities were analyzed by spectral and symbolic analysis. The baroreflex was evaluated by cross-spectral analysis between the HP and SAP series.
The groups did not differ in relation to VO , HP and SAP variabilities, and BRS at the beginning of the protocol. TG increased the endurance of the PFM after training. PFM contraction did not change the HP and SAP variabilities, and BRS at the 18th week. After the training, the TG presented lower SAP mean, lower BF of SAP variability, and higher BRS than CG.
Acute PFM contractions did not alter HP and SAP variabilities and BRS, but PFMT resulted in a lower SAP mean and higher BRS in trained pregnant when compared to the untrained.
评估骨盆底肌肉（PFMs）收缩的运动方案对孕妇静息时心率（HP）和收缩压（SAP）变异性及压力反射敏感性（BRS）的急性和慢性影响，并评估该渐进性运动方案是否被研究中的孕妇耐受良好。
我们通过阴道触诊、阴道测压和心肺运动试验评估了 48 名 18 周妊娠的女性。她们被分为对照组（CG；31.75±3.91 岁）和训练组（TG；30.71±3.94 岁）。在 19 和 36 周妊娠时，在进行 10 次 PFMs 收缩之前和之后，在静息时收集心电图和非侵入性外周 SAP 数据。TG 从第 20 周到第 36 周进行 PFMT。通过频谱和符号分析对 HP 和 SAP 变异性进行分析。通过 HP 和 SAP 序列之间的交叉谱分析评估压力反射。
在方案开始时，两组在 VO 、HP 和 SAP 变异性以及 BRS 方面没有差异。TG 在训练后增加了 PFM 的耐力。PFMs 收缩在 18 周时并未改变 HP 和 SAP 变异性以及 BRS。经过训练，TG 的 SAP 平均值较低，SAP 变异性的 BF 较低，BRS 较高。
急性 PFM 收缩不会改变 HP 和 SAP 变异性及 BRS，但与未经训练的 CG 相比，PFMT 可使训练中的孕妇的 SAP 平均值降低和 BRS 升高。
