The acute post-exercise increase in Interleukin-6 (IL-6) is correlated with muscle hypertrophy, but it does not add predictive value beyond local muscle factors like AR and p70S6K.

The inflammatory response to exercise, specifically IL-6, is correlated with muscle growth. However, this is likely a byproduct of local muscle adaptation rather than the primary driver. Focus on training consistency rather than trying to manipulate inflammation.
