Your fast-twitch and slow-twitch muscle fibers are separated into three distinct types.Slow-twitch fibers contain type 1 muscle fibers, while your fast twitch fibers contain both type 2a and type 2b.The percentage of each muscle fiber differs among everyone, and from one muscle to another in the same individuals, according to Fitness: The Complete Guide, by International Sports Sciences Association.hoto Credit Digital Vision./Photodisc/Getty Images. Your skeletal muscle contains two types of muscle fibers: fast-twitch and slow-twitch. Your fast-twitch and slow-twitch muscle fibers are separated into three distinct types.
Type IIa fibers are in the middle of the muscle fiber spectrum, as they are less fatigue resistance, produce more muscular force, and contract at a faster speed than slow twitch fibers.Type IIb: Fast Twitch Fibers.or recreational athletes though, commitment to practice and training will play a far more significant role in performance level than muscle fiber type alone will. So, the three types of muscle fibers are slow twitch (Type I) and fast twitch (Types IIa and IIb).
