Summary Introduction

To differentiate:

Between the fast twitch and the slow twitch muscles

Introduction:

The muscles utilize ATP generated by either aerobic or anaerobic pathways. Some muscle fibers rely on one method more than the other. For example the muscle that rely on the anaerobic source of ATP such as the fermentation or creatine phosphate pathway are the fast twitch muscles while the ones that rely on the cellular respiration are the slow twitch muscles.
