    A randomized controlled trial found that physical performance in adults 65 and older was significantly improved by group physical activity and behavioral health sessions. The 777 participants were randomly assigned to receive either three healthy aging education sessions or 64 one-hour physical activity sessions plus 21 45-minute behavioral maintenance sessions over the course of a year.

    The one-hour group physical activity sessions were conducted in community settings twice a week for 12 weeks, and then once a week for another 40 weeks. Activities included strength-based exercises and games, and were individualized for each participant. Current ability, muscle soreness, and fatigue were taken into account, allowing participants to progress at their own pace. Refreshments and socializing followed each physical activity session. Behavioral maintenance sessions incorporated behavior change techniques and encouraged ongoing engagement in physical activity, including group classes, home-based exercise, walking, and active travel.

    Physical function was measured with the Short Physical Performance Battery, a tool that assesses the performance of basic physical functions relevant to everyday life, including walking speed, ease of rising from a chair, and balance. A year after the study ended, participants in the intervention group still showed improved physical functioning.

    Mobility limitations can greatly reduce quality of life, generate substantial health and social care costs, and increase risk of death. Sedentary behavior increases mobility limitations. While the type of program used in this study may not be available to you, this research demonstrates how engaging in group classes at your own pace and finding ways to increase your physical activity in your daily life can have a real impact on your physical well-being. The expansion of virtual programs aimed at increasing physical activity may be a good option, at least as a start.
