Abstract

Sprinting speed is critical for success across many sports. Lower-body muscle size is important, but it is difficult to determine which muscles have the greatest influence on speed, and it is unclear how much variance in speed between athletes can be explained by variance in muscle size alone. The purpose of this study was to determine how much variance in on-field sprinting speed can be explained…
