- Primary Outcome Measures
Name Time Method nanticipated jump landing quality will be assessed using the landing error, standing error and time to stabilization.<br>These variables will be determined at the point of landing.<br>Landing on the wrong leg (left instead of right and vice versa) will be recorded as a landing error.<br>Inability to hold a stable landing position for at least 10 seconds will be recorded as standing error. Time to stabilisation describes the capacity to regain a stable stance after landing as quickly as possible and how long a participant takes after landing to assume a stable posture will be recorded as time to stabilization.<br>
- Secondary Outcome Measures
Name Time Method Single leg hop for distance will be measured and compared.<br>Participants will stand on one leg behind a marked line and hop forward as far as possible, land on the same leg and hold for at least 2 seconds. The distance between the starting line and the heel of the foot will be measured and recorded as the single leg hop for distance.
