Studying the impacts of physical activity on healthy aging.

Research relevance

This research will deepen our understanding of the factors that contribute to frailty, and how to prevent it.

Increasing Physical Activity to Fight Frailty

By 2024, one in five Canadians will be over the age of 65. Although many older adults have good health, many are frail. The increasing prevalence of frailty and shifting age distributions will have profound implications in Canada for population health, clinical practice and health policy.

Dr. Olga Theou, Canada Research Chair in Physical Activity, Mobility and Healthy Aging, is working to deepen our understanding of what causes frailty, how we can assess it, and what lifestyle changes can prevent and treat it. Specifically, she and her research team aim to understand how frailty can best be identified and managed in various settings. They are also examining whether increasing physical activity and reducing sedentary behaviours may lead to improved outcomes.

Theou and her team are also investigating the interactive effects of sedentary behaviours and physical activity in older adults and developing interventions that will improve their health outcomes and lighten the burden of chronic disease on people and the health care system.

Ultimately, Theou’s research will help address the challenge of caring for an aging population and contribute to the development of policies that support healthy aging.
