Research Impact Summary: Maximal sprinting in humans requires the contribution of various muscle–tendon units (MTUs) and joints to maximize performance. The plantar flexor MTU and ankle joint are of particular importance due to their role in applying force to the ground. The contribution of the ankle joint and plantar flexor MTU performance in the key phases of sprinting (start, acceleration, and maximum velocity) is unclear, warranting a synopsis of the available literature. Examining the musculotendinous properties that contribute to improved plantar flexor MTU performance is also of interest as a plantar flexor MTU with more architecturally favourable and more rapid contractile kinetics can enable greater ground forces to be applied during progressively shorter ground contact periods as sprinting speed increases. This narrative review examines the contribution of the ankle joint and plantar flexor MTUs across the phases of sprinting (start, acceleration, and maximum velocity), alongside the musculotendinous properties that contribute to improved plantar flexor MTU performance.
