In addition, the increase in body fat and decrease in muscle flex may result in less fluid movements during the growth spurt and may increase the risk of overuse injuries in girls. Girls entering puberty are at particularly high risk for dropping out of physical activities, making anticipatory guidance particularly important to encourage continued participation. Healthy Lifestyles Parents are a major influence on a child’s level of physical activity. By participating in physical activity (e.g., biking, hiking, playing basketball or baseball) with their children, parents emphasize the importance of regular physical activity and show their children that physical activity can be fun. Par- ents’ encouragement to be physically active signifi- cantly increases a child’s activity level.3 Children
