What are some key characteristics that differentiate muscular sprinters from other types of athletes?

Muscular sprinters typically have a higher percentage of fast-twitch muscle fibers, which provide explosive power for short bursts of speed. They also tend to have lower body fat percentages and higher levels of muscle mass, particularly in their legs. Additionally, sprinters often have a higher anaerobic capacity, allowing them to generate energy quickly without relying on oxygen for sustained performance.
