我们探讨了职业高尔夫球手和高水平业余高尔夫球手之间的练习和实际推杆击球的差异，以及练习击球如何反映推杆距离的细微差异。我们分析了挥杆幅度，冲击速度，和加速度曲线的杆头。加速度曲线表明，运动控制模式的实践中风不同于实际中风。为了明确不同推球距离对练习击球的影响，并分析练习击球对实际击球的解释程度，我们进行了个体回归分析。根据决定系数和斜率的大小，将所有被试的练习笔画分为三种策略和五种类型。这意味着练习击球的目的在不同的高尔夫球手之间是不同的。大多数高尔夫球手在他们的练习击球中使用个人速度标准，这导致了基于他们标准的不同推杆距离。出乎意料的是，我们发现专业人士和高水平业余爱好者之间的技能水平没有显著差异。这项研究的结果意味着，即使是专业的高尔夫球手与优秀的技术，实践中风并不重复实际中风。然而，大多数高水平的高尔夫球手采用距离依赖的控制策略略有不同的推杆距离。
We explored how practice and actual putting strokes differed between professionals and high-level golf amateurs, and how practice strokes reflected subtle differences in putting distances. We analysed swing amplitude, impact velocity, and acceleration profile of the club-head. The acceleration profiles showed that the motor control pattern of the practice stroke differed from that of the actual stroke. To clarify the effects of different putting distances on the practice stroke and to analyse how much the actual stroke could be explained by the practice stroke, we conducted individual regression analyses. The practice strokes of all participants could be divided into three strategies and five types by the coefficient of determination and the slope. This implies that the purpose of the practice stroke varied among golfers. Most golfers used the individual velocity criteria in their practice strokes, which resulted in different putting distances based on their criteria. Unexpectedly, we found no significant difference in skill level between professionals and high-level amateurs. The results of this study imply that the practice stroke does not duplicate the actual stroke, even for professional golfers with excellent skills. However, most high-level golfers adopted distance-dependent control strategies for slightly different putting distances.
