What is a likely outcome for a young child who is physically active?

A young child who is physically active is likely to experience increased bone density. Engaging in physical activities, such as running, jumping, and playing sports, plays an essential role in strengthening bones during critical developmental years. Weight-bearing exercises stimulate bone formation and contribute to overall skeletal health, which is particularly important in childhood when bones are still growing and developing.

Increased bone density aids in preventing conditions such as osteoporosis later in life, making physical activity particularly valuable for long-term health outcomes. Additionally, a physically active lifestyle can promote muscular strength, coordination, and balance, further benefiting a child's physical development.

The other options represent outcomes that are generally contrary to the benefits associated with regular physical activity in children. For example, physically active children typically experience lower risks of social isolation and higher energy levels due to the endorphins released during exercise.
