Project Outline

Large energy transfers during landing tasks require a considerable neural demand in the control of the musculoskeletal system. Many acute lower limb injuries occur within a short latency from contact with a floor surface during landing tasks. In preparation for landing the lower limb is subconsciously regulated in accordance with the expected perturbations and mechanical properties associated with the ground contact. It has been demonstrated that animals are capable of accurately regulating leg mechanics in anticipation and interaction with a surface. Despite these control capabilities it is a common perception that athletic activity on hard and non-compliant surfaces is associated with an intrinsic injury risk. However, evidence is available to suggest that the variability within a surface may be more relevant for injury risk than the absolute mechanical properties of a surface. The act of landing on an unknown surface presents a difficult motor control task as the individual must attempt to predict the impact conditions and regulate the body to maintain optimal stability. These mechanical strategies are largely unknown and have direct implications in an elite sporting setting such as Australian rules football and other field sports where variable or unsuitable playing surfaces are continually referred to with reference to injury mechanisms.
