| Abstract: | Performance in sprint exercise is determined by the ability to accelerate, the magnitude of maximal velocity and the ability to maintain velocity against the onset of fatigue. These factors are strongly influenced by metabolic and anthropometric components. For example, muscle fiber type has been purported to be one of the factors underlying sprint performance, with enzymatic adaptations and hypertrophy of prime movers. |
