EMS Theory Comments

Dan,
Since you seem very well versed in muscle physiology,

here is the distinction I’ve been struggling with, which you could help me with. What would be the right terminology to distinguish between the following?
[ul]
[li]Minor muscle adaptions, i.e. those that involve only increase of cross section of the muscle, and
[/li][li]Major muscle adaptions that involve a reorganization of muscle fibers types, i.e. significant change in the percentage of slow and fast twitch.
[/li][/ul]
I’m attaching an example to clarify* what I mean. Can you help?
Giovanni
