## Summary

Looking at dozens of trials in older adults with frailty or muscle loss, researchers checked whether exercise calmed chronic inflammation. Exercise meaningfully lowered TNF-alpha, an inflammatory protein linked to muscle wasting. But it did not budge two other common inflammation markers, IL-6 and CRP. So exercise helps with inflammation in frail seniors, but only partially.

## Practical Takeaway

This review suggests exercise may reduce some inflammation markers in frail older adults, but not all.
