Physical activity across adulthood in relation to fat and lean body mass in early old age: findings from the Medical Research Council National Survey of Health and Development, 1946-2010.

ABSTRACT: Fat and lean body mass have important implications for health and physical functioning in older age, and physical activity is purported to be an important modifiable determinant. However, our evidence-based understanding of its role is limited. We examined the associations of physical activity, assessed both by self-report (using data on leisure time physical activity (LTPA) collected on 4 occasions over a 28-year period) and objectively (using 5-day heart rate and movement monitoring), with fat and lean mass at ages 60-64 years in 1,162 British participants from the Medical Research Council National Survey of Health and Development in 1946-2010. Higher objectively assessed physical activity energy expenditure (PAEE) at ages 60-64 years was associated with lower fat mass and android (abdom
