Inflammation: the major regulator of muscle growth nobody talks about

  • Inflammation is crucial for muscle repair and growth, contrary to its negative reputation as something to be suppressed.
  • Inflammation serves as a signal for the immune system, helping address tissue damage and the presence of foreign agents like viruses.
  • Strength training causes inflammation in muscles, initiating repair and growth, especially regulated by Interleukin-6 (IL-6), a cytokine with both pro-inflammatory and anti-inflammatory actions.
  • Chronic inflammation, indicated by high resting levels of IL-6 and C-reactive protein, can erode tissues and inhibit muscle gains, while acute spikes in IL-6 post-exercise are beneficial for muscle growth.
  • Elevated inflammation in non-responders to strength training highlights excessive inflammation's role in lacking muscle development.
  • Lowering body fat percentage is essential as high body fat correlates with chronic inflammation, which masks signals for muscle repair, making muscle gains difficult.
  • Avoiding unnecessary suppression of inflammation is advised; common interventions like anti-inflammatory drugs, excessive vitamins, and cold therapies can blunt necessary inflammatory responses needed for muscle repair and growth.

What’s the optimal body fat range for muscle growth?

Cut or bulk? Many people see this simply as a question of personal preference, and of course to a large extent it is.
