This thesis (comprised of the literature review and empirical paper) aimed to explore the correlation between physical activity and mood in pregnant women. The literature review of this portfolio presents a narrative review of the research exploring the correlation between physical activity and mood in the general pregnant population. The findings of the review suggest that physical activity improves mood in this population. The empirical paper investigates the correlation between physical activity and mood over the duration of pregnancy. The findings suggest that increased physical activity from before pregnancy to the second trimester improves mood. The Summary of Clinical Experience is an outline of my experiences on 4 different clinical placements. The Table of Assessments outlines the titles of all assessments completed whilst on the clinical training programme.
