First-time Parents Physical Activity Intervention

This study will be investigating whether a theory-based physical activity intervention can maintain/improve moderate to vigorous intensity physical activity measured via accelerometry of new parents over the eight months of having a child compared to a control group of new parents. Hypothesis: The theory-based condition will change salient underlying motives (theory of planned behaviour constructs) for physical activity. Health-related fitness and quality of life will also be higher for this condition in comparison to the control condition. (Note: improvements in both groups of mothers may occur due to recovery from pregnancy, but our hypotheses will still hold). All outcomes will remain significantly higher at eight months in the theory-based condition compared to the standard condition
