What is one consequence of physical inactivity in adolescents?

The consequence of physical inactivity in adolescents that is most relevant is the increased risk of obesity. When adolescents are not engaged in regular physical activity, their energy expenditure decreases, which can lead to an imbalance between calories consumed and calories burned. This imbalance can contribute to weight gain over time and ultimately increase the likelihood of obesity. Obesity during the adolescent years can further lead to a range of health issues, including type 2 diabetes, cardiovascular diseases, and psychological effects, further emphasizing the importance of maintaining an active lifestyle during these formative years.

In contrast, decreased muscle strength can occur due to inactivity, but it is not as directly associated with the immediate consequences of inactivity as obesity. Improved cardiovascular health and enhanced social skills are generally outcomes of being active rather than consequences of inactivity. Therefore, the choice highlighting the increased risk of obesity captures a significant and well-documented consequence of physical inactivity in adolescents.
