Landing after the jump is a high risk mechanism that can be followed by numerous injuries of the lower extremity, especially in the knee. Lower limb injuries often are created in a condition that the person is not able to prepare for possible injury. Some studies have shown that appropriate and effective preparation during landing can reduce the injury risk. The present study aims to evaluate the effects of preparation on knee frontal plane projection angle (KFPPA) during landing tasks among the female athletes. In this cross-sectional study, 22 female recreational athletic activities will be selected using non-random sampling and measured KFPPA during the diverse landing tasks. Furthermore, all subjects will perform four common screening tasks as follows: the double leg drop landing and single leg drop landing for tasks with preparation; double leg jump landing and single leg jump landing for tasks without preparation. Several studies indirectly have investigated the influence of preparation on biomechanical factors of the lower extremity but direct impact of preparation has not been into consideration. Accordingly, the present study protocol will evaluate direct influence on the KFPPA during the landing in the recreational female athletes.
