An increasingly popular exercise modality for women is high-intensity interval training (HIIT). Limited research has assessed HIIT during pregnancy, and as a result, pregnant women may inquire about HIIT on their own through online searches. The purpose of this study was to systematically search and critically evaluate online resources that women may access when inquiring about performing HIIT during pregnancy.
Following previously published methodology, we systematically examined the online search engine Google with the terms 'HIIT' and 'pregnancy'. Using the as a reference, we identified evidence-based safety recommendations that apply to all prenatal exercise regimes. All selected links were assessed for whether or not they included evidence-based exercise and pregnancy safety recommendations. Descriptive analyses were performed to report the frequency of each construct.
Seventy-six links were retrieved, and 33 relevant links were selected for inclusion. The majority of the retrieved links recommended that women should consult a healthcare provider before beginning any exercise programme (67%), and modify the intensity and types of exercises in the active HIIT bout based on general pregnancy-related changes (73%) and individual comfort level (55%). Just under half of the links recommended modifying intensity based on prepregnancy activity level (46%), offered trimester-specific recommendations (42%), and only 12% mentioned contraindications to exercise.
Publicly accessible information online on HIIT during pregnancy does not routinely adhere to evidence-based safety recommendations for prenatal exercise. Further research on HIIT during pregnancy and public dissemination of findings is required.
高强度间歇训练（HIIT）是一种在女性中越来越受欢迎的运动方式。针对孕期进行HIIT的研究有限，因此，孕妇可能会通过在线搜索自行了解HIIT。本研究的目的是系统搜索并严格评估女性在询问孕期进行HIIT相关信息时可能获取的在线资源。
按照先前发表的方法，我们使用关键词“HIIT”和“怀孕”对在线搜索引擎谷歌进行了系统检索。以[具体参考内容未给出]为参考，我们确定了适用于所有产前运动方案的循证安全建议。对所有选定的链接评估其是否包含循证运动和怀孕安全建议。进行描述性分析以报告每个结构的出现频率。
共检索到76个链接，选择了33个相关链接纳入研究。大多数检索到的链接建议女性在开始任何运动计划前应咨询医疗保健提供者（67%），并根据与怀孕相关的一般变化（73%）和个人舒适度（55%）调整HIIT运动环节中的运动强度和类型。略少于一半的链接建议根据孕前活动水平调整强度（46%），提供孕期各阶段的具体建议（42%），只有12%提到了运动的禁忌证。
关于孕期HIIT的在线公开信息通常未遵循产前运动的循证安全建议。需要对孕期HIIT进行进一步研究并向公众传播研究结果。
