Think Extensively About the Factors Responsible for Bone Health: BMD is influenced by multiple factors including nutrition, exposure to sunlight, ethnicity, physical activity and protein intake. Low weight, or low body mass index (BMI), is a well documented risk factor for future fracture, whereas a high BMI appears to be protective. Exercise is an important dynamic factor that imparts mechanical loading on a living bone tissue. The bone is subject to constant alternation of loading during exercise. It adapts to this alternation by changing its mass and skeletal geometry. Physical exercise is...
