How does strength training impact bone density?

Strength training has a substantial positive impact on bone density, and the correct answer reflects this benefit. Engaging in activities that place stress on the bones, such as resistance training, stimulates bone remodeling. This process encourages the body to build new bone tissue, thereby increasing overall bone density. As a result, individuals who regularly participate in strength training are at a reduced risk for osteoporosis—a condition characterized by weak and brittle bones.

The mechanical loading of bones from lifting weights or resistance exercises prompts osteoblasts, the cells responsible for bone formation, to increase their activity. This not only strengthens bones but also enhances the structural integrity of the skeletal system. Thus, consistent participation in strength training contributes to healthier bones over time, promoting bone density and overall skeletal strength.

In summary, the statement that strength training increases bone density and reduces the risk of osteoporosis accurately encompasses the important relationship between resistance exercise and skeletal health.
