Bones are dynamic tissues undergoing constant remodeling throughout most of our lives. Powered by interconnecting nerves and blood vessels, bones are a maze of mineral depositing cells, known as osteoblasts. At the same time, another group of cells, osteoclasts are busy eating away at the calcium crystals. The balance of osteoblast to osteoclast activity regulates the total bone strength (or bone density).
Exercise that applies forces to the bone activates both osteoblasts and osteoclasts. Over time the combined activity of these cells builds a new stronger and fracture resistant set of hardworking bones.
Professor David Cameron-Smith explains both men and women can take steps from a young age to improve their bone density and help prevent osteoporosis. Along with a healthy and calcium-rich diet, weight bearing and strength-training activities play an important role in healthy bones. Regular exercise including jumping, lunges, skipping, brisk walking, basketball and running can help improve bone strength.
