Story Brief

New Australian research is shedding light on why walking often becomes slower and more tiring with age. The findings suggest that the body gradually gives up some movement efficiency in favor of staying stable and upright. Led by researchers at Flinders University and the University of Canberra, the study found that aging is associated with a "safety-first" walking strategy. This approach emphasizes stability instead of speed and energy efficiency, helping explain why older adults may fatigue more quickly and also face a greater risk of falling.
