Participation in Olympic weightlifting, the Valsalva maneuver, and acute or prolonged supine weightlifting during pregnancy are cautioned against; however, these recommendations are based on expert opinions as opposed to empirical evidence. The aim of this study was to examine the training and health outcomes of individuals who engaged in heavy resistance training during pregnancy.
A total of 679 individuals who lifted at least 80% one-repetition maximum during pregnancy participated in an online survey.
Participants were primarily recreational athletes (88%, 332 out of 675) engaged in CrossFit™ (61%, 410 out of 675) and/or weightlifting (49%, 332 out of 675) during pregnancy. Most participants reported no complications during pregnancy or delivery (66%, 388 out of 589), whereas 57% (241 out of 426) reported urinary incontinence following pregnancy. Participants who maintained pre-pregnancy training levels until delivery reported significantly less reproductive complications than those who ceased training levels prior to delivery (p = 0.006). Most respondents engaged in Olympic lifting (72%, 311 out of 432) and lifting in a supine position (71%, 306 out of 437), whereas fewer reported use of the Valsalva maneuver during pregnancy (34%, 142 out of 412). Most returned to weightlifting following delivery (89%, 400 out of 447, average: 3.2 ± 3.0 months), including Olympic lifting (81%, 300 out of 372, average: 4.0 ± 3.4 months) and Valsalva (62%, 213 out of 341, average: 4.5 ± 3.6 months).
Individuals who engaged in heavy prenatal resistance training had typical perinatal and pelvic floor health outcomes that were not altered whether they engaged in, or avoided Olympic lifting, Valsalva or supine weightlifting.
参与奥林匹克举重、瓦尔萨尔瓦动作以及怀孕期间急性或长时间仰卧举重被警告禁止；然而，这些建议是基于专家意见，而不是经验证据。本研究旨在检查怀孕期间进行重度阻力训练的个体的训练和健康结果。
共有 679 名在怀孕期间至少举起一次重复最大重量的 80%的个体参与了在线调查。
参与者主要是娱乐运动员（88%，675 人中的 332 人），他们在怀孕期间从事 CrossFit ™（61%，675 人中的 410 人）和/或举重（49%，675 人中的 332 人）。大多数参与者报告在怀孕期间或分娩时没有并发症（66%，589 人中的 388 人），而 57%（426 人中的 241 人）在分娩后报告尿失禁。维持产前训练水平直至分娩的参与者报告生殖并发症明显少于在分娩前停止训练水平的参与者（p=0.006）。大多数受访者从事奥林匹克举重（72%，432 人中的 311 人）和仰卧举重（71%，437 人中的 306 人），而较少报告在怀孕期间使用瓦尔萨尔瓦动作（34%，412 人中的 142 人）。大多数人在分娩后恢复举重（89%，447 人中的 400 人，平均：3.2±3.0 个月），包括奥林匹克举重（81%，372 人中的 300 人，平均：4.0±3.4 个月）和瓦尔萨尔瓦（62%，341 人中的 213 人，平均：4.5±3.6 个月）。
从事重度产前阻力训练的个体具有典型的围产期和盆底健康结果，如果他们从事或避免奥林匹克举重、瓦尔萨尔瓦或仰卧举重，这些结果不会改变。
