Inverse dynamics and quasi-static calculations are often used to estimate the net joint torques exerted during sporting movements but such methods make a number of assumptions that may not be appropriate for high loading impact situations. These assumptions include the use of rigid segments to represent the limbs in the body and the use of simple frictionless pin joints to connect these segments. This paper uses a constrained forwards dynamics model for determining the net joint torque at the knee during running jumps and compares the results with the moments calculated using quasi-static and pseudo inverse dynamics.
