Horizontal deceleration ability is defined as an athlete’s ability to proficiently reduce whole body momentum, within the constraints, and in accordance with the specific objectives of the task (i.e. braking force control), whilst skilfully attenuating and distributing the forces associated with braking (i.e. braking force attenuation).

During horizontal deceleration, braking steps exhibit a distinct ground reaction force profile characterised by high-impact peak forces and loading rates.

Horizontal deceleration ability is an adaptive coordinated outcome whereby neuromuscular and biomechanical qualities interact to optimise braking impulse and achieve desired reductions in whole body momentum.
