A recent study published in the Canadian Medical Association Journal highlights the significant health benefits of physical activity for older adults. Engaging in regular physical activity has been linked to a reduced risk of mortality, improved cognitive function, and a lower incidence of chronic illnesses. The study emphasizes the importance of incorporating physical activity into clinical care for older adults.
By Dr. Liji Thomas, MDReviewed by Benedette Cuffari, M.Sc.Jan 30 2025 Despite overwhelming benefits, physical activity remains underutilized in clinical care for older adults.
Thirty minutes of moderately vigorous physical activity for at least five days every week reduces the risk of death from any cause by 31%, with these health benefits increasing with greater durations of physical activity. Alternatively, lower levels of physical activity are associated with poorer health outcomes, with one hour or 30-60 minutes of resistance exercise every week reducing an individual’s mortality risk by 27% and 10-20%, respectively.
Physical activity, including strength training, supports muscle strength and mobility, while also preventing frailty. Thus, current recommendations advise all older individuals to maintain regular physical activity, even frail people or those at risk for falls, as it promotes bone and muscle strength, coordination, and balance.
Patients who are at an increased risk of falls should have individualized and gradually progressive exercise schedules. Although brisk walking may not be recommended for these patients, high-intensity interval training with necessary precautions is considered safe and well-tolerated. Physical activity has been shown to prevent heart failure, coronary artery disease, chronic obstructive pulmonary disease, and osteoporosis. Furthermore, physical activity can mitigate the severity of existing illnesses by improving functional independence and reducing the number of medications or treatments needed.
