Can Walking Reduce Sarcopenia? A Comprehensive Guide to Aerobic Exercise and Muscle Health

According to a 2025 study in *BMC Geriatrics*, a wearable-assisted walking program significantly improved muscle mass and physical function in older adults. This evidence confirms that staying active is a vital strategy to combat age-related muscle loss, prompting the question: can walking reduce sarcopenia effectively on its own? The research suggests that while walking is highly beneficial, combining it with other exercises offers the most comprehensive protection.
