The Relationship between Maximum Lower Extremities Joint Moment with Maximum Vertical Ground Reaction Force during Single Leg Drop Landing

The objective of this study was to evaluate the relationship between maximum lower extremities joint moment with maximum ground reaction force during single leg drop landing. Thirty athletes volunteered to participate in this study. Kinetics and kinematics variables during single leg drop landing were collected by motion analysis and force plate. The results indicated that there was no significant correlation between peak moment of flexion, adduction and rotation of hip and ankle joint with maximum vertical ground reaction force. However, significant correlation was identified between peak moment of knee and subtalar joint with maximum ground reaction force. The findings of this study showed that there is a relationship between vertical ground reaction force and moment of knee and subtalar joint. Therefore, whatever the vertical ground reaction force is higher, the amount of load to this joints is more and can make the joints more susceptible to injury.
