Regular physical activity offers numerous health benefits as people age, including reduced risk of sarcopenia, falls, disability and premature mortality. It has been identified as one of the most effective non-pharmacological health-enhancing interventions for older adults. However, recent evidence has demonstrated that physical activity has broader emotional and social impacts for older adults, such as reduced loneliness and improved mental wellbeing. This keynote will explore the role of physical activity in healthy ageing and introduce day-to-day physical activity as a more than just a health-related behavior, which has implications for future policies and interventions.
