Changes in strength may be explained by neural adaptations and changes at the local muscle level.

“yes i think some people would say that some people are of the opinion that the exercise-induced changes are probably predominantly neural i i'm not there yet i think that there could be some local changes at the muscle um and that might be able to explain why some groups get stronger that's not just neural in other words maybe the muscle uh at the local level is actually getting better at responding to forceful contractions so maybe it's you know how it deals with calcium or how the myosin head binds maybe there's some alterations there qualitatively that aren't due to muscle size but i don't know what what those would be necessarily”

“I I do think that there probably is a huge neural component but I I don't know that there um there isn't something going on at the local level that is independent of a change in muscle size but but but it is still muscular perhaps”

“but I I do think that there's a probably a neural component but I think that there could also be some changes at the local level that might explain some of those changes in string and I I think we can discuss that a little bit later as well but there could be some some you know changes at the me in head or ch and calcium release and things of that sort so I don't have any good evidence that that is actually happening but just some ideas behind why someone might get stronger following exercise”
