Physical activity is critical for preventing disease, enhancing functional independence, and maintaining the overall health of older adults.

By 2025, at least 20% of Canada’s population will be aged 65 or older, with the number of individuals over 85 expected to triple within two decades. Despite this demographic shift, prolonged life expectancy often does not equate to a higher quality of life. According to national data, over 80% of Canadian adults fail to meet the recommended physical activity guidelines, increasing their risk of functional decline, particularly in the presence of chronic diseases or fall susceptibility.
Dr. Jane Thornton, an Associate Professor at Western University, emphasizes that “physical activity is one of the most important ways to maintain functional independence in older age.” Research highlights that 150 minutes of moderate-intensity physical activity weekly reduces mortality risk by 31% and prevents over 30 chronic conditions, including coronary heart disease, type 2 diabetes, osteoporosis, depression, and dementia. Regular exercise also positively influences cognitive function and mental health, enhancing quality of life.
Engaging in physical activity improves muscle strength, enhances bone density, and reduces the risk of falls. Furthermore, it alleviates symptoms of osteoarthritis, promotes a better mood, and facilitates independence in daily living. The World Health Organization (WHO) recommends that adults, including seniors, engage in 150–300 minutes of weekly physical activity to sustain their health.
Given the prevalence of chronic diseases in older adults, clinicians are encouraged to adopt tailored strategies when prescribing physical activity. Dr. Samir Sinha underscores the importance of incorporating resistance training to strengthen muscles. The WHO’s “5As“ approach—Ask, Assess, Advise, Agree, Assist—provides a structured framework for healthcare professionals to support older patients in adopting and maintaining active lifestyles.
Despite its well-documented benefits, physical activity remains underutilized within healthcare systems. The article notes that “old age or disability are not contraindications to exercise, but rather a good reason to prescribe it.“ Integrating regular physical activity into healthcare for older adults extends lifespan and significantly enhances life quality.
