Fast glycolytic muscle fibers fast glycolytic muscle fibers have fewer,smaller myofilaments generate lots of power and depend on anaerobic pathways to make adenosine triphosphate (atp) are prevalent in postural muscles of the back are abundant in muscles of the lower limbs, contract quickly, and are oxygen-dependent have abundant myoglobin and numerous mitochondria

Generate lots of power and depend on anaerobic pathways to make adenosine triphosphate (ATP)

Explanation:

Fast glycolytic muscle fibers generate lots of power mainly through anaerobic glycolysis. They are thick muscle fibers that can produce bursts of energy for a short span of time, but they fatigue easily. Looking at it more closely, you will find that they do not have many mitochondria because they don't rely on aerobic pathways and they are sometimes described as white fibers because they have limited blood supply.

These types of muscles fibers are called fast twitch fibers because they can generate more force at a faster rate and allow quick movements. But then again, only for a short period before they start to fatigue.
