Thank you for the opportunity to help you with your question!

Type I 

 Type I fibers are otherwise called moderate jerk strands. They are red in shading because of the vicinity of substantial volumes of myoglobin thus oxygen and high quantities of Mitochondria. Because of this they are extremely impervious to weariness and are equipped for delivering rehashed low-level withdrawals by creating a lot of ATP through a aerobic metabolic cycle. Hence the muscles containing for the most part sort I filaments are regularly postural muscles, for example, those in the neck and spine because of their perseverance capacities Also, competitors, for example, marathon runners have a high number of this kind of fiber, mostly through hereditary qualities, somewhat through preparing.

Type lla

Type IIa fibers are likewise once in a while known as quick oxidative filaments and are a half breed of sort I and II filaments. These filaments contain countless and Myoglobin, thus their red shading. They fabricate and part ATP at a quick rate by using both oxygen consuming and anaerobic digestion system thus deliver quick, solid muscle compressions, despite the fact that they are more inclined to exhaustion than sort I filaments. Resistance preparing can transform type IIb filaments into sort IIa because of an increment in the capacity to use the oxidative cycle.

Type IIb

Frequently known as quick glycolytic strands they are white in shading because of a low level of myoglobin furthermore contain few mitochondria. They create ATP at a moderate rate by anaerobic digestion system and separate it exceptionally quicky. This outcomes so, quick blasts of force and fast exhaustion. As specified over, this sort of fiber can be transformed into sort IIa strands by resistance preparing. This is a positive change because of the expanded exhaustion resistance of sort IIa filaments. These strands are found in extensive amounts in the muscles of the arms.
