Sort of, but whether it’s beneficial or pathologic is more complicated than whether it’s short or long duration.

Chronic or sustained inflammation is a sign of dysregulation, but acute inflammation can also be pathologic.

Moreover, the inflammation in physical exercise, in physiologic conditions, is actually beneficial (it’s physiologically angiogenic and anabolic). In other words, the benefits of exercise don’t just outweigh the harms of inflammation: rather, exercise can create well-regulated, physiological and beneficial inflammation.

Inflammation is as complex a topic as cancer (in fact the two are pretty much inseparable): it’s a fascinating beast!
