Resistance training positively impacts bone density by stimulating the deposition of calcium in bones, thereby enhancing their strength and reducing the risk of osteoporosis. The mechanical stress from resistance exercises encourages bone remodeling, leading to increased bone mass. This type of training is particularly important for older adults, as it helps counteract age-related bone density loss. Regular resistance training can improve overall bone health and contribute to better functional mobility, ultimately enhancing quality of life and reducing injury risk.
