Aging Alters How the Ankle Works During Walking
A study conducted by researchers at Flinders University and the University of Canberra has identified age-related changes in ankle function during walking that contribute to slower gait and increased fatigue among older adults. Published on June 13, 2026, the findings are based on movement data from 107 healthy individuals ranging in age from 26 to 86 years. Understanding these biomechanical shifts is crucial for developing interventions that help seniors maintain mobility and independence.
The research revealed that older adults are more likely to simultaneously activate opposing muscles around the ankle—a phenomenon known as muscle co-contraction. This stiffens the joint, which helps improve balance at the moment the foot strikes the ground. However, this increased stiffness also means the muscles work harder but generate less forward propulsion. As people age, they push off the ground more weakly with each step, resulting in shorter strides and a reduced walking speed.
Compensatory Strategies and Expert Recommendations
The nervous system of older adults compensates for these age-related changes by prioritizing safety and stability over movement efficiency. While this helps prevent falls, it can lead to faster fatigue, make prolonged walking more difficult, and reduce the ability to quickly recover balance after tripping or slipping.
As Cody Lindsay noted: 'With age, the body increasingly prioritizes stability over efficiency.'
To improve physical fitness in older adults, experts recommend exercise programs that focus on:
- muscle strengthening;
- balance development;
- coordination;
- proper muscle coordination during walking.
Cody Lindsay advises regular physical activity, balance exercises such as tai chi, strengthening of the lower leg muscles, and activities that enhance coordination.

This research underscores the importance of physical activity for older adults, as changes in walking mechanics can significantly affect their quality of life. Given the identified changes, tailored exercise programs may be key to preventing falls and maintaining mobility—critical factors for preserving independence in later years.
As older adults face challenges in maintaining mobility, it's essential to consider other health factors that may impact their well-being. For instance, the use of unnecessary supplements can have adverse effects on seniors' health, complicating their physical condition further.
