Unlock Power And Speed: Understanding Fast Twitch Muscle Fibers
Fast twitch muscle fibers, classified as Type II fibers, prioritize power generation. They possess a larger diameter and rely heavily on glycolytic metabolism, enabling rapid anaerobic energy production. These fibers excel in power-based activities, such as sprinting and weightlifting, due to their high contraction speeds. However, their limited aerobic capacity and susceptibility to fatigue hinder…
