Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| Single leg hop for distance will be measured and compared. 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. | — |
Primary
| Measure | Time frame |
|---|---|
| Unanticipated jump landing quality will be assessed using the landing error, standing error and time to stabilization. These variables will be determined at the point of landing. Landing on the wrong leg (left instead of right and vice versa) will be recorded as a landing error. 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. | — |
