Global pregnancy physical activity guidelines recommend most individuals engage in at least 150 min/week of moderate-to-vigorous physical activity. However, exercise beyond these limits has received little investigation and assessment of safety. There is no consensus on safe durations of exercise bouts within the literature, with recommendations ranging from 10 to 60 min.
The aim was to examine the impact of long-duration endurance exercise (≥ 60 min/session) on maternal-fetal health outcomes.
A total of 331 participants who engaged in long-duration endurance exercise during pregnancy participated in an online survey.
Participants were aged 33.2 ± 6.1 years and had 2.1 ± 1.2 pregnancies. Subgroup analyses were performed comparing: (1) those who exercised within guidelines, ≤ 300 min/week during the third trimester (T3), and (2) those who exercised above guidelines, > 300 min/week during T3. Participants who exceeded guidelines experienced reduced odds of delivery complications (odds ratio [OR] 0.12, 95% confidence interval [CI] 0.015-0.988, p < 0.05) but increased the odds of diastasis recti abdominis postpartum (OR 4.13, 95% CI 1.059-16.135, p < 0.05).
Exercising > 300 min/week in T3 reduces odds of delivery complications, but increases odds of diastasis recti abdominis postpartum. Endurance exercise > 300 min/week in T3 is generally well tolerated in a highly active population.
全球孕期身体活动指南建议大多数人每周至少进行150分钟的中等至剧烈身体活动。然而，超出这些限制的运动很少得到安全性的调查和评估。文献中对于单次运动的安全时长尚无共识，建议时长从10分钟到60分钟不等。
旨在研究长时间耐力运动（≥60分钟/次）对母婴健康结局的影响。
共有331名在孕期进行长时间耐力运动的参与者参加了一项在线调查。
参与者年龄为33.2±6.1岁，怀孕2.1±1.2次。进行了亚组分析，比较：（1）在孕晚期（T3）按照指南运动、每周≤300分钟的参与者，以及（2）在T3运动超出指南、每周>300分钟的参与者。超出指南的参与者分娩并发症的几率降低（优势比[OR]0.12，95%置信区间[CI]0.015 - 0.988，p<0.05），但产后腹直肌分离的几率增加（OR 4.13，95%CI 1.059 - 16.135，p<0.05）。
在T3每周运动>300分钟可降低分娩并发症的几率，但会增加产后腹直肌分离的几率。在T3每周进行>300分钟的耐力运动在高活动水平人群中通常耐受性良好。
