Laura the sprinter has more muscle strength than Susan the distance runner. Laura's muscles can produce more force because as a sprinter she is more powerfully built. She has thick muscles, strong thighs and calves that helps her burst from the starting line. Sprinters also have strong upper bodies and powerful arms to pump them up and give them full speed while aiding balance. Distance runners like Susan on the other hand develop long, lean muscles specifically in the lower body and it best suits them for covering ground. While both runners do aerobic training, sprinters lift weights too to add muscle.
