Fast-twitch muscle fibers, often referred to as type II fibers, are a category of skeletal muscle cells distinguished by their rapid contraction speed and reliance on anaerobic metabolism. These fibers are crucial for activities demanding explosive power and short bursts of intense effort, such as sprinting, jumping, and weightlifting. There are two main subtypes of fast-twitch fibers: Type IIa and Type IIx.
Type IIa fibers, also known as intermediate fast-twitch fibers, possess characteristics of both fast and slow-twitch
Type IIx fibers are the fastest and most powerful of all muscle fiber types. They are specialized
The proportion of fast-twitch fibers in an individual's musculature can influence their athletic potential. Training that
