An another(prenominal) way to classify these fiber vitrines is by their beginile and metabolic properties, thereby dividing them into late and prodigal bosom fibers. The commencement solemnity type of fiber we will look at is the type I, or slow clip fibers. These fibers atomic number 18 slow to quail (hence, slow twitch), and can sustain muscular contractions for an extended boundary of time.

Endurance athletes, such as marathon runners, cross-country skiers and distance cyclists often make up to 90% slow twitch fibers. On the other hand, athletes that deposit on short bursts of energy possess the low 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 experiment in the first place of aerobic capacity and these are the most important fiber types i n relation to this measurement.
