What r/AdvancedFitness is:

  • A place to discuss fitness, health, nutrition, and training programs beyond the beginner or introductory stages.
  • A place for you to ask questions and learn from others on the above topics.
  • A gathering place for enthusiasts, athletes, researchers, and everyone in between to discuss shared interests.
  • Somewhere where intelligent discourse and thoughtful questions are the norm, not the exception.

What r/AdvancedFitness isn't:

  • A place for you to spam your crappy products.
  • A sub that will dispense medical advice. If you have a condition that is affecting your lifts, you need to talk to a medical professional.
  • AF is not a place where information will be spoon fed. If you want a 'tl;dr' or 'ELI5' you're in the wrong place.
  • This is not a place for memes, rage comics, image macros, or things that provide no value.
  • This is not a place to post threads where the only discussion to be had is congratulating the OP.

Can muscle fibers grow without being activated? [af]

I’ve seen Greg talk about this before but today I came across this Chris Beardsley article. https://sandcresearch.medium.com/can-muscle-fibers-grow-without-being-activated-7c920e94e099 I agree with everything he says about passive tension and how it’s not going to cause hypertrophy in relaxed muscle. Also for maximal hypertrophy as many fibers as possible need to be activated. However, I think he completely skips over possible systemic effects weightlifting can have on fibers that haven’t been activated. For example things like increased atp, nitric oxide, and blood flow could effect nearby fibers. Effecting the local muscle metabolic milieu as a whole. It seems highly unlikely that atrophy/hypertrophy is strictly which fiber got activated and which didn’t and that local metabolic factors also don’t play a role.
