Tiivistelmä

Individuals with a healthy weight tend to be more physically active than obese individuals. However, the interplay between different types of body tissues with physical activity and fitness is complex with greater total body mass and fat mass increasing the strength and energy demands for bodily movement and greater skeletal muscle mass being associated with increased force production making it easier to move one’s body. Despite this complex interplay, previous studies investigating the associations between body composition and physical activity have only considered the proportions of fat mass and fat free mass separately and ignored the compositional nature of the body. Furthermore, the effect of body composition on physical activity has not been studied previously in longitudinal studies with significant changes in body composition during the follow-up period. Thus, the aim of this cross-sectional and longitudinal study is to investigate the effect of body composition on physical activity level and the role of physical fitness in that association in middle-aged women and older adults using compositional data analysis and random-effect cross-lagged panel models. This study will enhance our understanding on the underlying reasons for the global inactivity pandemic and the results will provide tools for individually tailored health promotion and physical activity assessment.
