在运动学习过程中获得的各种类型的表演前准备行为中，在执行实际动作之前执行的练习动作的效果尚未完全理解。因此，本研究采用高尔夫推杆任务，调查如何在准备阶段的练习运动会影响在执行阶段的运动控制的准确性和熟练程度会影响这种关系。为研究击球速度对运动学和最终球位的影响，对职业高尔夫球手和业余高尔夫球手的练习击球速度进行了实验性的控制，分别在以下三种条件下进行：等距离条件，即在练习击球和实际击球过程中目标距离相同;和不包括练习划水的“否”条件。结果表明，基于最后的球的位置，在相同的条件下的实践中风与最高的准确性水平在实际中风在专业和业余选手。在混乱的条件下，无论技术水平如何，实际击球的速度都会受到击球前阶段更快或更慢的击球的影响。练习和实际击球之间的这些关系意味着高尔夫球手有效地利用了在练习击球期间获得的动觉信息作为实际击球的参考。此外，不同水平的业余选手在无条件下的杆头速度显著快于同等条件下。因此，目前的结果意味着练习击球的作用在专业和业余选手之间可能有所不同。
Of the various types of preperformance preparatory behavior that are acquired during motor learning, the effect of a practice motion performed just prior to execution of an actual motion is not yet fully understood. Thus, the present study employed a golf putting task to investigate how a practice motion in the preparation phase would affect the accuracy of motor control in the execution phase and how proficiency would influence this relationship. To examine the impacts on kinematics and final ball position, the velocities of practice strokes made by tour professional and amateur golfers were experimentally manipulated in the following three conditions: the equal condition, which presented a target that was at the same distance during the practice strokes and the actual stroke; the confusing condition, which had two different distances during the practice and actual strokes; and the no condition, which did not include a practice stroke. The results, based on final ball position, indicated that practice strokes in the equal condition were linked with the highest accuracy levels during the actual stroke in both professionals and amateurs. In the confusing condition, regardless of skill level, the velocity of the actual stroke was influenced by a faster or slower stroke during the pre-shot phase. These relationships between the practice and actual strokes imply that the golfers effectively utilized kinesthetic information obtained during the practice strokes as a reference for the actual stroke. Furthermore, the differences in proficiency level indicated that the club head velocity of amateurs in the no condition was significantly faster than in the equal condition. Therefore, the present results imply that the role of a practice stroke may differ between professionals and amateurs.
