Abstract

PurposePhysical activity unquestionably maintains and improves health; however, physical activity levels globally are low and not rising despite all the resources devoted to this goal. Attention in both the research literature and the public policy domain has focused on social-behavioral factors; however, a growing body of literature suggests that biological determinants play a significant role in regulating physical activity levels. For instance, physical activity level, measured in various manners, has a genetic component in both humans and nonhuman animal models. This consensus article, developed as a result of an American College of Sports Medicine-sponsored round table, provides a brief review of the theoretical concepts and existing literature that supports a significant role of genetic and other biological factors in the regulation of physical activity.ConclusionsFuture research on physical activity regulation should incorporate genetics and other biological determinants of physical activity instead of a sole reliance on social and other environmental determinants.

Abstract

Physical activity (PA) is a broad concept containing a variety of different human behaviors that share the common denominator of expected beneficial effects on mental and somatic health. PA behaviors appear to "run in the family" for example, the chance of one family member being a regular exerciser increases the chance of all other family members to be, or to become, an exerciser. Familial aggregation of PA can be investigated by computing correlations among relatives such as siblings, and parents and their offspring. In the final set of 27 adult twin studies, we encountered a large variation in measurement instruments and PA measures used. By far the largest common denominator was the use of survey-based methods using subjective PA reporting on self or family members. In large population-based twin registries, surveys are often considered the only feasible strategy.
