In the present study, the influences of two practice methods on movement correction during interceptive action was examined. Fourteen men practiced intercepting a moving virtual target. One group practiced on a target that changed velocity from 4 to 8 m/sec. during the trial (within-trials change group). The other group practiced under Slow and Fast conditions, in which the initial velocity (4 or 8 m/sec.) remained constant (inter-trials change group). After the practice, both groups showed similar decreases in temporal errors in interception of an acceleration target. However, the within-trials change group showed non-corrected movements, whereas the inter-trials change group showed corrective movements. Thus, the practice methods for within-trials and inter-trials change resulted in different corrective strategies to acceleration target.
在本研究中，考察了两种练习方法对拦截动作中运动纠正的影响。14 名男性练习拦截移动的虚拟目标。一组在试验中（组内变化组）练习一个目标，该目标的速度从 4 米/秒变为 8 米/秒。另一组在慢和快条件下练习，其中初始速度（4 或 8 米/秒）保持不变（组间变化组）。练习后，两组在拦截加速度目标时的时间误差都有相似的减少。然而，组内变化组表现出未纠正的动作，而组间变化组表现出纠正性动作。因此，组内和组间变化的练习方法导致了对加速度目标的不同纠正策略。
