This course draws upon previous course work in biophysical, behavioural and socio-cultural aspects of physical activity and links them together within the context of girls’ and women’s health across the lifespan. Particular attention will be given to how physical activity decreases the risk of disease in girls and women and how physical activity assumes a different role in health and well-being during different phases of the lifespan. Students will also be introduced to issues related to the promotion of physical activity for women, the importance of the inclusion of women and girls in research examining the impact of physical activity and the unique aspects of the response of girls and women to activity.
