Why Staying Active Helps Older Adults Walk Better
Share
As people grow older, it’s common to see changes in how they walk. Steps may get shorter, muscles feel weaker, and walking might become slower or less steady. These changes aren’t just about getting older—they also relate to how active someone is. As we age, our muscles lose strength, our joints get stiffer, and our brain’s ability to control movement can slow down.
The Hidden Cost of Walking
Older adults often spend more energy walking than younger people. This means simple tasks like going to the market or walking up stairs can feel harder. This “walking cost” isn’t just about age—it’s heavily influenced by physical activity. In fact, research shows that older adults who are less active use about 20% more energy to walk compared to their more active peers.
Why Physical Activity Makes a Difference
Regular physical activity doesn’t just build muscle—it also improves how the nervous system controls movement. Older adults who stay active tend to:
- Walk with longer, more stable steps
- Use their muscles more efficiently
- Keep better balance
- Show smoother movement patterns
Staying active seems to slow down the aging process in the muscles and nerves used for walking. It helps the body move more like a younger person, even in old age.
What Happens If You're Not Active
Older adults who are less active tend to rely more on their hips and upper legs to walk. This shift puts more strain on those areas and can lead to faster fatigue or joint problems. They also show more "co-activation" of muscles—meaning opposing muscles contract at the same time. While this may help with balance, it also uses more energy and makes walking less efficient.
Signs of Healthy Walking
More active older adults tend to:
- Keep their trunk (upper body) straighter while walking
- Have better ankle movement when their foot hits the ground
- Use their calf muscles more during the “push-off” phase of walking
- Activate key muscles at just the right time
These patterns are linked to lower effort, better stability, and a reduced risk of falling.
So, What Should You Do?
You don’t need to become a marathon runner to see benefits. Even light to moderate activity, like walking, dancing, or gardening for a few hours a week, can make a real difference. Strength training also helps by improving muscle power and joint support.
Here are a few practical tips:
- Walk daily – Even 20–30 minutes a day can help.
- Add strength training – Focus on legs and balance exercises twice a week.
- Stretch regularly – This helps keep joints and muscles flexible.
- Stay consistent – Regularity is more important than intensity.
Final Thoughts
Aging is natural, but how we age is something we can influence. Staying active not only strengthens muscles but also helps the brain and nerves work better together during walking. The key message from this research is simple—move more to walk better, stay independent, and feel stronger as you age.
