Effect of practice of a throwing skill in one body position on performance of the skill in an alternate position.

The effect of learning a throwing skill with the body in one position on performing the skill in a different position was investigated. 40 normal women, aged 20 to 34 years, were randomly assigned to experimental or control groups. Subjects threw darts from two positions, sitting on a Balans chair or reclined on a slanted table. Practice and transfer sessions each included 4 sets of 5 throws. Performance was significantly poorer after switching positions than when remaining in the same position. Performance after practice in an alternate position was significantly worse than performance after no practice. These findings suggest that practicing a skill in one position may not improve learners' ability to perform that skill in a different position.
