so if hypertrophy seems to be coming relatively easy for the trainee in the 5 rep range does one assume that he he is fast twitch fiber dominant? and what is going on with the slow twitch fibers in the lower rep ranges. and im being specific for 5.
As far as I understand, it wouldn't stimulate this muscle fiber type much, so it wouldn't hypertrophy or get stronger
Fast and slow twitch muscle fibers are not evenly distributed, some muscles do seem to be predominantly one or the other, for example, triceps, fast, biceps, slow.
Some of this is logical when you look at the type of work a muscle or the movement of the muscle. Some of it is genetic, and as Southern Lord mentioned, stimulus/training is thought to switch a percetage of fibers.
If you are getting significant growth in the 5 rep range,then that muscle group is probably mostly fast twitch, which also shows more hypertrophy than slow twitch.
I think people don't pay much attention to the rep ranges and fiber types as the growth from slow twith stimulation is going to take longer to noitce as the hyypertrophy is less, and it will take a lot more res for an 'enduarnace'peroid of time for results.
