The present study examined the influence of attentional focus on performance during a long-distance throwing task. Twelve participants executed three maximum-effort, long-distance baseball throwing attempts in three focus conditions: internal focus on wrist flexion (wrist internal focus), internal focus on the separation between pelvis and upper torso orientations (torso internal focus), and external focus on the ball path (external focus). Compared with the external focus and torso internal focus conditions, performance was poorer in the wrist internal focus condition. Performances were not different in the torso internal and external focus conditions. In addition, attentional focus affected the release angle of the ball but not its initial velocity. Our results reveal that the body part targeted for internal focus of attention and the forcefulness of the motor activity can be as important to motor performance as whether the attention is internal or external.
本研究考察了注意力焦点对长距离投掷任务中表现的影响。12名参与者在三种焦点条件下进行了三次竭尽全力的长距离棒球投掷尝试：关注手腕弯曲的内部焦点（手腕内部焦点）、关注骨盆与上半身方向之间分离的内部焦点（躯干内部焦点）以及关注球的轨迹的外部焦点。与外部焦点和躯干内部焦点条件相比，手腕内部焦点条件下的表现较差。躯干内部焦点和外部焦点条件下的表现没有差异。此外，注意力焦点影响了球的出手角度，但不影响其初速度。我们的结果表明，注意力内部焦点所针对的身体部位以及运动活动的力度对运动表现的重要性，与注意力是内部还是外部一样。
