Strength training can help improve bone density by placing mechanical stress on the bones. When the bones are subjected to this type of stress, they respond by becoming stronger and denser.
During strength training exercises, the muscles pull on the bones, which stimulates the production of new bone tissue. This process, known as bone remodeling, helps to increase bone density and strength.
In addition to the mechanical stress placed on the bones during strength training, the increased muscle mass that results from strength training can also help improve bone density. The muscles help to support the bones and provide a load-bearing effect that can help stimulate bone growth.
Overall, strength training can be an effective way to improve bone density and reduce the risk of osteoporosis and fractures in older adults. It is generally recommended that older adults engage in strength training at least twice a week, using moderate to high intensities. It is important to consult with a healthcare professional before starting a strength training program, as some medical conditions or medications may affect an individual's ability to engage in strength training.
