Document Summary
Innate motor programs: specific to individual muscles being used in movement and built in eg. -learned motor programs: when moves become automated, adjusted to specific muscles. Feedback: closed loop system where movement is adjusted due the postural disturbances that. Feedforward: automated response that is adjusted to rapid movement relies on internal motor. Voluntary: can be reflex initially, but if needs to be corrected becomes feedback. When weight is expected feedforward movement is used, anticipated. When weight is unexpected feedback control is used to adjust movements programs to get the. Successful in time and space, efficient, smooth, avoid injury/harm, and adaptable to the env: describe feedback and feed forward control, including limitations. What movement characteristics determine the relative contribution of each type of control? occur -relys on sensory info to specify the motor response causes a lag programs cannot correct for errors: compare a reflex and a voluntary movement.
