Which of the following is a benefit of regular physical activity?

Regular physical activity offers several significant benefits, and one of the most important is the enhancement of bone and muscle strength. Engaging in exercise helps to stimulate bone growth and increases bone density, reducing the risk of osteoporosis and fractures later in life. Moreover, physical activity contributes to muscle strength and endurance, which is essential for overall physical health, functional independence, and the prevention of injuries.

Stronger bones and muscles are not only beneficial for daily activities but also improve performance in sports and recreation. This increase in physical capability can lead to a more active lifestyle, further promoting health and well-being.

In contrast, options indicating increased fatigue, decreased sleep quality, and reduced academic focus are all effects that would not typically arise as benefits of regular physical activity. Rather, engaging in regular exercise is generally associated with increased energy levels, improved sleep quality due to better physical health, and enhanced cognitive function, which can positively influence academic performance.
