currently there are these views about muscle growth
Myofibril hypertrophy, hypertrophy in the actual muscle fibers, which is caused by lifting loads more than 80% of your 1 rep max and weights around 65% will not trigger it, long rests, heavy weights, your fast twitch fibers don't contract against light weights
This is also called "overload" long term gains
Sarcoplasmic hypertrophy, which is the hypertrophy in the sarcoplasm and is reached by lifting submaximal loads, short rests, light weights
you can lose A LOT of size in a short period of time if most of what you have is sacroplasmic hypertrophy
(guys talk about how they stopped working out for one week and lost 10 pounds of muscle, which i don't understand because i could
stop working out for a month and not lose any)
Muscle microtears: which is you have to damage the muscle then repair it, it will grow
this theory just dismisses everything, your muscle fibers are not being "overloaded" what is being damaged exactly? fast twitch fibers?
as long as you damage and recover your muscles will grow, you can damage a muscle with any kind of weight pretty much
.....
so do we "damage" the muscles or "overload" them?
why doesn't science give us an answer already?
has there been no studies on this?
i'm sure someone will post "Just lift" but it would help to know what is optimal and what is not, to not waste time
get to work, men in lab coats
