Which of the following is an effect of inadequate physical activity during childhood?

Inadequate physical activity during childhood can lead to delayed physical development. During this critical period of growth, children require regular physical activity to support the development of essential motor skills, muscle strength, and overall physical health. Engaging in physical activities helps to build coordination, balance, and endurance, which are crucial for developing a child's ability to perform daily tasks and participate in sports or recreational activities later in life.

When children do not engage in sufficient physical activity, they may experience delays in reaching important developmental milestones, which can have long-term implications for their physical health and fitness levels. Furthermore, a lack of physical activity can also contribute to issues such as obesity and related health concerns, further compounding the effects of delayed development.

In this context, the other options are not accurate reflections of the consequences of inadequate physical activity in children. For instance, improved social skills, increased academic performance, and enhanced emotional resilience are typically encouraged through regular participation in physical activities and sports, which promote teamwork, discipline, and stress relief, respectively.
