What are the characteristics of slow oxidative muscle fibers. These muscle fibers are an endurance athletes best friend. Based on metabolic pathways utilized muscle fibers are categorized as slow oxidative SO fast oxidative FO and fast glycolytic FG.

Type II fibers can also be further divided into fast oxidative muscle fibers type IIa and fast glycolytic muscle fibers type IIbIIx.

Based on metabolic pathways utilized muscle fibers are categorized as slow oxidative SO fast oxidative FO and fast glycolytic FG. In slow oxidative fibers slow is for having the ATPase that hydrolyze ATP slowly while oxidative stands for the aerobic respiration pathway for metabolizing glucose. Begingroup If I remember correctly the slow oxidative fibers compose mostly structural muscles thing multifidus longissimus capitus muscles which are on a lot of the time but dont retract quickly like fast glycolitic fibres. Type I fibers are characterized by low forcepowerspeed production and high endurance Type IIX fibers are characterized by high forcepowerspeed production and low endurance while Type IIA fall in between the two.
