Describe the relationship between physical activity and muscular / skeletal health

Participating in regular physical activity is important for building and preserving the health of the muscles, bones, and joints. This is especially true for young children and adolescents, as physical activity helps to build muscular strength as well as improve motor control and encourages bone growth and strength. Most of the musculoskeletal benefits of physical activity focus on older adults, as muscle and bone health tend to deteriorate with age. As individuals get older, physical activity can become an important preventive health measure for osteoporosis, the loss of bone mineral content and bone strength. Osteoporosis is a common condition in older adults, particularly older adult females, and can lead to increased risk for hip and spine fractures. Adults who lead inactive lifestyles have a much higher risk of developing osteoporosis than those who maintain a physically active lifestyle. The stress placed on the skeletal system during weight-bearing activities, such as running or jumping, can help to strengthen bones and can slow bone loss as adults age. Regular physical activity can also protect against the proximal cause of osteoporotic fracture-falls. Physical activity is also important for maintaining joint health and has even been shown to be a useful treatment for certain types of arthritis.?
