This question is about Cycling
Yes, moderate-intensity exercise for 20 to 30 minutes/day, including cycling, can reduce inflammation [1].
Exercise’s anti-inflammatory impact can be attributed to multiple factors, such as increased production of adrenaline, cortisol, and growth hormone; visceral fat loss; improved levels of anti-inflammatory myokines; and diminishing the expression of toll-like receptors (TLRs) in immune cells. Conversely, it’s been shown that strenuous exercise may increase inflammatory markers.
