The relationship between fitness and bone health is crucial as regular weight-bearing exercises stimulate bone formation and enhance bone density. High-impact activities, such as running or strength training, place stress on bones, prompting them to strengthen in response. This is particularly important in preventing osteoporosis and fractures, especially in older adults. Additionally, adequate intake of calcium and vitamin D supports bone health. A consistent fitness routine fosters not just muscular strength but also maintains skeletal integrity, contributing to long-term mobility and quality of life.
