I couldn't agree more 2 lap, you said it better than I did:
"As you said, muscle fibre composition actualy has very little to do with performance... almost to the extent at which its worth ignoring by coaches and athletes outside a reasearch setting. Muscle fibre composition is rarely a limiting factor (apart from in diseased states and elderly people), it can't be used to predict performance and cannot be measured easily; therefore its best to focus on other aspects during training and national squad/talent selection."
It is good to use physiological data to design training programs and what not, but I feel it is getting a bit out of hand when it is used as the only criteria, or the main criteria, for judging a riders potential. It is also a useful tool to use to find out your weaknesses and to then work on those.
