| Abstract: | Myofiber types are classified into four types，which are Ⅰ，2a，2b and 2x，according to myosin heavy chain polymorphismThe four fiber types represent four metabolic features that are slow oxidative type，fast oxidative type，fast glycolytic type and mediate typeIn this article，myofiber types from myofiber constitution，classification，characteristics and transformation were introduced. Meanwhile，it is principal to expound how myofiber types affect the pork quality，and the factors influencing myofiber types. |

| Keywords: | myosin muscle fiber meat quality pig |
