questions about different muscle fiber types in different muscle groups

True or False:

  1. There is appreciable evidence that some muscle groups are composed predominantly of slow-twitch fibers (like the finger extensors, gastrocnemius) while others are composed of mostly fast-twitch fibers (like, say, quads and anterior delts).

  2. It follows from this that it is wise to select things like frequency, rep ranges and intensity partly on the basis of which types of fibers will be most involved in moving the weight?

  1. To a degree, yes.

  2. No. The muscles don’t really respond differently.
