Scientists Uncover Why Walking Gets Slower and More Exhausting As We Age

Key Points:
- A new study from Flinders University and the University of Canberra reveals that aging shifts walking strategy to prioritize balance and safety over efficiency, resulting in slower and more tiring gait.
- Researchers found that older adults increase co-contraction of opposing ankle muscles, stiffening the joint to improve stability but reducing push-off power, stride length, and walking speed.
- This safety-first approach helps prevent instability but may increase fatigue, reduce recovery ability from trips or slips, and contribute to a higher fall risk among older adults.
- The study suggests that exercise programs for aging individuals should focus not only on strength but also on balance, coordination, and muscle control to maintain mobility and confidence.
- The findings aim to inform improved fall prevention and rehabilitation strategies to support healthy aging and independence.
