Does Exercise Reduce Inflammation in Older Adults? A New Umbrella Review Finds a Small Effect

Inflammation tends to creep up with age. Dozens of trials say exercise nudges it back down, and a 2026 review of 21 reviews explains why that answer comes with an asterisk.

The short answer

Probably a little. A 2026 umbrella review of 21 reviews linked exercise in older adults to small drops in two inflammation markers, CRP and TNF-alpha, while results for IL-6 were mixed. But it rated the certainty very low for every marker. The reasons to stay active in later life go well beyond these blood tests.

What is inflammaging?

Inflammation is your immune system's alarm. A short burst helps you heal. The kind that worries scientists is different: a low, steady hum that never fully switches off.

Researchers have a name for the version that builds with age. They call it "inflammaging": chronic, low-grade inflammation that develops as we get older and helps drive age-related diseases. Aging is linked to this sustained low-grade inflammation, and that in turn has been linked to age-related diseases and to death.

So the question matters. If exercise can turn the hum down, that would be one more reason to keep moving.

Scientists usually track it with three blood markers. CRP (C-reactive protein) is a protein the liver makes when inflammation is up. IL-6 and TNF-alpha are signaling proteins that immune cells use to raise the alarm.

The trials mostly say yes

On paper, the case looks good. A 2023 meta-analysis (a study that pools many studies) combined 49 trials with 1,898 adults aged 65 and up. Exercise training lowered all three markers. The effects were small to moderate, and largest in people with chronic diseases.

Blood markers alone are not enough to prescribe exercise just to lower inflammation, but the case for staying active stands.From a 2026 umbrella review in Front Immunol

A 2026 network meta-analysis went bigger. It pooled 55 randomized trials with 3,516 healthy middle-aged and older adults and compared types of exercise head to head. Strength training lowered CRP the most. Aerobic training did best for IL-6 and TNF-alpha.

And a 2026 meta-analysis of 36 randomized trials in older adults found strength training lowered a group of inflammation markers that includes CRP and IL-6. The effects were bigger with at least 3 sessions a week and with heavier weights.

So why the asterisk?

This is where the new review comes in. An umbrella review is a review of reviews. Instead of pooling trials, it steps back and grades how trustworthy the existing reviews are.

A team searched six databases through March 1, 2026, and found 21 reviews on exercise and inflammaging markers in older adults and adults with chronic diseases. Exercise was linked to small drops in TNF-alpha and CRP. IL-6 results ranged from a drop to a slight rise.

Then they graded the reviews themselves. Of the 21, 11 rated "critically low" for quality, 9 rated low, and only 1 rated moderate. Using a standard grading system called GRADE, the certainty was very low for every marker. When the team set aside the weakest reviews, the signal got smaller.

The authors drew a careful line. Blood markers alone, they wrote, are not enough to prescribe exercise just to lower inflammation. But that does not change the broader advice to stay active, which rests on other health and function outcomes. That is the honest middle. It is also why we grade this Moderate, not Strong.

Who sees the change?

The answer seems to depend on who is exercising.

In 19 randomized trials with 728 healthy adults aged 60 and up, strength training lowered CRP. It did not change IL-6 or TNF-alpha. It did improve leg strength and how far people could walk in six minutes.

In 26 trials of older adults with frailty or major muscle loss (sarcopenia), exercise lowered TNF-alpha but not IL-6 or CRP.

A 2026 analysis of 146 studies in older adults found that women, people with health problems, and people with overweight or obesity improved more than others. The anti-inflammatory effects were stronger when people also lost weight or improved their blood sugar and blood fats, but they did not depend on those changes.

What about a lifetime of exercise?

Some people never stopped. A 2025 meta-analysis of 17 studies with 649 people compared lifelong "masters athletes" with untrained people their own age. The athletes had lower CRP and higher IL-10, a signal that calms inflammation. Compared with untrained young adults, though, they still had higher TNF-alpha and IL-6. These studies compare groups at one point in time, so they show a link, not proof that training caused it.

you have heart or lung disease, chest pain, dizziness or unusual shortness of breath when you exercise, a recent fall, surgery or fracture, joint problems you are being treated for, or frailty or major muscle loss, or if you are new to lifting weights.

Will you try it?

One tap. Results appear once 50 readers have voted, and the count is always real.

The bottom line

Inflammation tends to creep up as the years add up. Dozens of trials in older adults say exercise nudges it back down, and the newest review of those trials agrees on the direction. It just won't promise how much. That is fine. Strength, stamina and the walk to the mailbox were always the better reasons to move. A slightly calmer blood test is a bonus, and three sessions a week is a fair price for both.

Common questions

Does exercise reduce inflammation in older adults?

Probably a little. In 49 trials with adults aged 65 and up, exercise training lowered CRP, IL-6 and TNF-alpha by small to moderate amounts. A 2026 umbrella review found small drops in CRP and TNF-alpha but mixed IL-6 results, and it rated the certainty very low for every marker.

Is running good for inflammation?

Running is aerobic exercise, and aerobic training has a good record in older adults. In a 2026 network meta-analysis of 55 trials, aerobic training did best for IL-6 and TNF-alpha. A 2026 analysis of 146 studies found aerobic training was the most effective type overall, followed by strength training. None of these looked at running on its own.

Does yoga help reduce inflammation?

The evidence is thin. In one randomized trial of 84 adults with depression, 10 weeks of hatha yoga lowered IL-6 compared with a health education class. CRP and TNF-alpha did not change. That trial was not in older adults, and none of the large reviews in this article tested yoga on its own, so it is too early to say.

Does protein help exercise lower inflammation?

Maybe. A 2025 meta-analysis of randomized trials in older adults found exercise plus extra protein showed greater benefits for inflammaging markers than either one alone. The authors called for larger studies. Most of the evidence on exercise comes from exercise alone.
