Knee torque graph during jump
WebKnee At initial contact, the GRF is normally located anterior to the knee, but the GRF quickly moves posterior to the knee during the loading response. A flexion moment is the result, and knee extensors counter this moment to keep the knee from collapsing. WebUtilise plantarflexors to oppose the external torque. Knee GRF creates an anterior (clockwise) torque of the proximal segment (on top of distal segment) - wants to move into extension by the femur moving anteriorly on the tibia. Utilise flexors to oppose this torque …

WebKnee extensors of normal male vol- unteers tested eccentrically at 60, 120, and 1 80°/sec on the Kinetic Communicator by Chandler and Duncan showed a slight but signifi- cant decrease in average force with increased velocity (2).
Webthe knee extensors appears as mechanical work at the ankle joint and the height of the jump is significantly increased. This is because, as the jump proceeds and the knee straightens, the angular position changes of the knee have progressively less effect on vertical …
