The purpose of this study is to explore the differences in muscle activation when accelerating overground compared to running on an accelerated treadmill belt. A case study was conducted evaluating the muscle activation patterns of M. Gastrocnemius, M. Tibialis Anterior, M. Rectus Femoris and M. Biceps Femoris. Preliminary analyses tend to show that the changes in muscular activation needed overground to go from a steadystate to an accelerated run differ from the ones to go from a steady-state to an accelerated run on treadmill. This reinforces the conclusion of previous research on ground reaction forces and joint kinetics that accelerating on a standard motorized treadmill cannot be used as an alternative to train or investigate overground acceleration when running.
