Muscle fiber type can be measured in 3 ways: myosin ATPase histochemistry, immunohistochemistry, or (much less commonly) metabolic enzymes.
Changes in muscle fiber type can be2 presented as either changes in the proportion of fibers of a given type, or as changes in the absolute or relative cross-sectional area of the fibers.
Although all fiber types have a similar single fiber force, type II muscle fibers display a much faster shortening velocity than type I muscle fibers. A higher proportion of type II muscle fibers may therefore be beneficial for strength and power sports."
Do you suppose this is reconciliation enough or would you prefer the opinion of a high School PE teacher?
