Psychological Factors Associated with Physical Activity in Youth

WithKatrina J. Waldhauser, Geralyn R. Ruissen, Mark R. Beauchamp

With the increased popularity of, and reliance on, technology in recent years, it is not surprising that children and adolescents are spending large amounts of time in front of a screen and less time being physically active. Those who spend more time in sedentary behavior experience increased health risks, such as cardiovascular disease and obesity. Balanced against the costs of inactivity and sedentary lifestyles, engaging in regular and sustained physical activity has consistently been associated with an extensive range of physical/physiological and psychological health benefits that extend across the age span. Social cognitive theory represents one of the most widely applied theoretical models to examine how psychological factors coalesce to influence physical activity. Affect and affect-related constructs are critical psychological factors in understanding the adoption and maintenance of physical activity behavior.
