The mental and physical health benefits of exercise during pregnancy highlight the importance of understanding the determinants of pregnant women's physical activity. This paper presents a review of the existing research on pregnancy and physical activity, in order to (a) summarize the existing body of literature since 1986 examining changes in physical(More)
BACKGROUND When examining the prevalence of physical inactivity by gender and age, women over the age of 25 are at an increased risk for sedentary behavior. Childbearing and motherhood have been explored as one possible explanation for this increased risk. Post natal exercise studies to date demonstrate promising physical and psychological outcomes, however(More)
OBJECTIVE The objective of the current investigation was to examine if the effects of a group-mediated cognitive behavioural counselling plus exercise intervention were superior to the effects of a standard exercise care condition on postnatal mothers' self-regulatory efficacy (SRE), outcome expectations (OEs) and self-directed physical activity (PA).

BACKGROUND Pregnant women without medical contraindications should accumulate 30 min of moderate exercise on most days of the week, yet many pregnant women do not exercise at recommended levels. PURPOSE The purpose the study was to examine barriers to leisure-time physical activity (LTPA) and investigate barrier and exercise self-efficacy as predictors of(More)
Studies have demonstrated that postnatal women are at high risk for physical inactivity and generally show lower levels of leisure-time physical activity (LTPA) compared to prepregnancy. The overall purpose of the current study was to investigate social cognitive correlates of LTPA among postnatal women during a 6-month period following childbirth. A total(More)
The purpose of this study was to examine women's leisure time physical activity (LTPA) before pregnancy, during pregnancy, and through the first 7 months postnatal. Pre- and postnatal women (n = 309) completed the 12-month Modifiable Activity Questionnaire and demographic information. Multilevel modeling was used to estimate a growth curve representing the(More)
BACKGROUND Childhood obesity is a serious health concern affecting over 155 million children in developed countries worldwide. Childhood obesity is associated with significantly increased risk for development of type 2 diabetes, cardiovascular disease and psychosocial functioning problems (i.e., depression and decreased quality of life). The two major(More)
OBJECTIVE Health research has demonstrated that physical activity during the postnatal period may play a crucial role in managing the physical and psychological challenges that women face during these times of transition. To promote physical activity during the postnatal period, mother-and-baby exercise classes are offered through several health and fitness(More)
This feasibility study assessed the effects of an exercise plus group-based self-regulatory skills intervention on obese youths' physical activity, social cognitions, body composition and strength. Forty-three obese youth (male = 13, BMI > 95th percentile; 10-16 yrs) completed this 12-week intervention. Assessments were taken at baseline, week 6, 13 and 12(More)
a minimum of 45 minutes of moderate-to-vigorous physical activity 5 days per week—may help to reduce the risk of cancer development 15. Although these guidelines are based on scientific evidence, the American Cancer Society cautions that the evidence used to create this general guideline is not definitive because the research is unclear with respect to the(More)
