Limitations of animal running speed Limitations of animal running speed Limitations of animal running speed provides an overview of how various factors determine the maximum running speed.

There is no single determinant of maximum running speed: however, certain factors stand out against others and have been investigated in both animals and humans. These factors include: Muscle moment arms, foot morphology, muscle architecture, and muscle fiber type. Each factor contributes to the ground reaction force (GRF) and foot
