How Exercise Helps Older Adults Lower Diabetes Risk
Share
As people age, staying healthy becomes more important—and more challenging. One of the biggest health concerns for older adults is type 2 diabetes, a condition that affects how the body manages blood sugar. But here’s some good news: staying active can really help lower the risk.
Why Diabetes Is a Problem for Older Adults
Diabetes is becoming more common, especially in people over 65. In countries like South Korea, about 1 in 3 older adults has diabetes. This condition can lead to serious health issues like heart problems, nerve damage, and a lower quality of life. It also makes it harder to stay independent as we age.
The Power of Physical Activity
The World Health Organization recommends at least 150 minutes of moderate exercise a week (like brisk walking) and two days of resistance exercise (like lifting weights or using resistance bands). Sadly, many older adults don’t meet these goals, especially when it comes to resistance training.
But the study found that those who did meet these exercise goals had a much lower chance of having diabetes. In fact:
- Just doing enough leisure-time physical activity lowered the risk of diabetes by 28%.
- Doing resistance training at least twice a week lowered it by 31%.
- Doing both lowered the risk by 35–37%.
That’s a big difference, and it shows how important even small lifestyle changes can be.
Why Resistance Exercise Matters More Than You Think
Muscle loss is a natural part of aging, but it happens faster in people with diabetes. Resistance exercise helps maintain or even increase muscle, which in turn helps the body manage blood sugar better. That’s because muscles play a key role in using up glucose from the blood.
Interestingly, the study found that resistance exercise alone was even more helpful than aerobic activity in lowering diabetes risk for many older adults—especially those who weren’t overweight.
Practical Tips to Get Started
You don’t need to join a gym or lift heavy weights to benefit. Here are simple ways to add more activity to your week:
- Go for a brisk walk for 30 minutes, five days a week.
- Use resistance bands or do light bodyweight exercises (like squats, wall push-ups, or leg lifts) twice a week.
- Choose fun activities like dancing, gardening, or swimming to stay active without it feeling like a chore.
Final Thoughts
Being active—especially with both cardio and strength training—can help older adults lower their risk of diabetes and stay healthier for longer. Even if you haven’t been very active before, it’s never too late to start. Small changes now can lead to big health rewards in the future.
