概括
高强度功能训练,如CrossFit,当在怀孕期间适当修改时,似乎是安全的. 这项研究没有发现早产,低出生体重或对母亲或新生儿的不良结果的风险增加. 建议进行进一步的研究.
科学领域:
- 产科和妇科 产科和妇科
- 运动医学 运动医学
- 孕产妇和胎儿医学 孕产妇和胎儿医学
背景情况:
- 在怀孕期间定期体育活动 (PA) 降低了妊娠糖尿病,高血压疾病和过度体重增加的风险.
- 目前的指导方针建议适度强度的运动,但高强度功能训练 (HIFT) 的安全数据,如怀孕期间的CrossFit是有限的.
- 在怀孕期间与HIFT相关的潜在的孕产妇和胎儿风险仍然存在担忧.
研究的目的:
- 评估怀孕期间修改CrossFit训练的安全性.
- 为了比较继续CrossFit和匹配对照的孕妇在分娩时的妊娠年龄.
- 评估与持续高强度功能训练相关的孕产妇和新生儿结果.
主要方法:
- 追溯队列研究涉及132名孕妇 (44名CrossFit,88名对照) 在他们的第三个三个月.
- 从医疗记录和参与者问卷收集的数据.
- 主要结局:分娩时的妊娠年龄. 二次结果:出生体重,母亲的并发症,新生儿的结果. 多变量逻辑回归用于分析早产风险.
主要成果:
- 在CrossFit参与者和对照者 (39.3 vs 38.9周) 之间,在分娩时的妊娠年龄没有显著差异.
- 在这两组中,早产是罕见的;参加CrossFit并没有增加早产的几率 (aOR 0.4).
- 组间的平均出生体重,出生体重百分位数和孕产妇/新生儿不良结果是可比的.
结论:
- 在怀孕期间适当修改高强度功能训练 (CrossFit) 与早产,低出生体重或对母亲/新生儿不良后果的风险增加无关.
- 初步发现表明,修改后的HIFT与可观察到的危害无关.
- 需要进行更大规模的前性研究来确认安全性并制定最终的建议.

01:20Exercise and Cardiovascular Response
3.8K
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

01:07Teratogenicity
3.9K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
