This is actually not true. There is a significant and measurable amount of fiber type switching due to training. Dr. Andy Galpin is a field-leading researcher in this very phenomenon.

This is true

Again, if you can convert fiber types, there's probably some genetic ceiling we all have, but it's not a given from just looking at your untrained fiber makeup. Some one who is born on a farm and grew up moving hay all day gains a very large advantage because of something call "epigenetics". Your training history, your lifestyle, etc. all help determine your epigenetics and thus help determine your future potential.

Obviously, in some ways, it doesn't matter; you play the hand you're dealt and you go as fast as you can, and if you aren't genetically blessed, that's no reason to give up on a sport that you enjoy. On the other hand, it is something I find interesting from an analytical point of view - does anyone have any ideas?

Thanks in advance.
You can get a muscle biopsy and have your fiber type and percentage make up calculated/measured/analyzed.
