In two separate experiments, this study examined changes in motor pattern and performance accuracy when low-level throwers focused on internal variables, external variables, and/or velocity of throw. In Experiment 1 the task goal was to improve the throwing pattern. In Experiment 2 the task goal was to throw as accurately as possible at a target. The results of Experiment 1 indicated that increasing velocity was most effective for changing the throwing pattern, with external focus more effective than internal focus. The results of Experiment 2 indicated that external focus was the most accurate condition and increasing velocity was most effective for changing the throwing pattern.
在两项独立的实验中，本研究考察了低水平投掷者在关注内部变量、外部变量和/或投掷速度时，运动模式和表现准确性的变化。在实验 1 中，任务目标是改善投掷模式。在实验 2 中，任务目标是尽可能准确地向目标投掷。实验 1 的结果表明，提高速度对于改变投掷模式最有效，外部焦点比内部焦点更有效。实验 2 的结果表明，外部焦点是最准确的条件，提高速度对于改变投掷模式最有效。
