| We
used optimal control methods to study coordination and control of
the standing long jump. The standing long jump was simulated with
a 2-D five-segment model. The ankle, knee, hip, and shoulder joints
were modeled as revolute joints and were actuated by joint torques.
The magnitude of torque generated by the joint actuators was a function
of the activation, the joint angle, and the joint angular velocity.
The optimal activations to generate maximum length jumps were found
using a simulated annealing algorithm. The maximal jumps were determined
for two different cases for jumps with both free and restricted
arm movement.
