BREAK Project

According to the Canadian Health Measures Survey, Canadians aged 65 and over spend an average of more than 10 hours a day on sedentary behaviors, equivalent to nearly 75% of their waking hours. Sedentariness is defined as the sum of sedentary behaviors during waking hours that occur in a seated or lying position, resulting in low energy expenditure (e.g. watching television, reading, working at a computer, etc.). High sedentariness is associated with several harmful effects, such as metabolic dysfunction, the development of chronic diseases, and mental health issues, independently of the level of physical activity. Therefore, we believe it would be relevant to study the effects of breaking up sedentary behavior in this population in order to consider it as a complementary strategy to physical activity, potentially contributing to better cognitive and cardiometabolic health
