Scientific research has demonstrated that sprinters and marathoners have predominantly different muscle fiber types. Sprinters will have fast-twitch muscle fibers that create greater force and bear a faster contraction or response time. Marathoners have slow-twitch muscle fibers that create force slowly and remain contracted longer.
