On the other hand,! athletes that deposit on short bursts of energy possess the last-place levels of slow twitch fibers, often around only 25%. Athletes with a higher proportion of slow twitch fibers also normally have the highest VO2 max results, as this is a shew in the first place of aerobic capacity and these are the most important fiber types in relation to this measurement.
