Cool mama: Temperature regulation during high-intensity interval running in pregnant elite and recreational athletes.

Background: Regular exercise during pregnancy is beneficial, but athletes often exceed the recommended 150 min of moderate-intensity activity, incorporate high-intensity exercises. The upper limit for exercise intensity and duration on fetal and maternal safety remains uncertain. A concern is a maternal core body temperature of >39.

What is the effect of physical activity on duration and mode of delivery? Secondary analysis from the Norwegian Fit for Delivery trial.

Introduction: The beneficial effects of physical activity during pregnancy for the mother and offspring have been reported by several studies but there are conflicting results concerning the possible effect of physical activity on the course of labor and risk of cesarean delivery. This study presents secondary analyses from the Norwegian Fit for Delivery randomized controlled trial, aiming at studying the effect of a lifestyle intervention including group exercise classes, as well as the possible influence of physical activity level in late pregnancy, on labor outcomes.

Material And Methods: Healthy nulliparous women with singleton pregnancy were randomized to an intervention group, n = 303 (dietary counseling and twice-weekly exercise classes) or a control group, n = 303 (standard care).

Effect of a prenatal lifestyle intervention on physical activity level in late pregnancy and the first year postpartum.

Background: Despite documented health benefits for mother and baby, physical activity (PA)-level tends to decline in pregnancy. Overweight/obese and physically inactive women are two selected groups at increased risk of pregnancy complications. Thus, efficient strategies to maintain or increase PA-level in pregnancy and the postpartum period, especially among these women, are warranted.

Reliability and concurrent validity of the International Physical Activity Questionnaire short form among pregnant women.

Abstract: Sanda B, Vistad I, Haakstad LAH, Berntsen S, Sagedal LR, Lohne-Seiler H, Torstveit MK. Reliability and concurrent validity of the International Physical Activity Questionnaire short form among pregnant women.

Background: The International Physical Activity Questionnaire short-form (IPAQ-SF) is frequently used to assess physical activity (PA) level in the general adult population including pregnant women.

Evaluation of implementing a community-based exercise intervention during pregnancy.

Objective: to evaluate the implementation of a community-based exercise intervention (the Norwegian Fit for Delivery study) during pregnancy.

Design: descriptive, explorative.

Setting: healthcare clinics in southern Norway, including urban and rural settings.
