我们的目的是确定熟练的球员如何调节线性和角脉冲，同时保持平衡，在高尔夫球挥杆。11名技术高超的高尔夫球手用6号铁杆和球杆进行了挥杆表演。对后腿和目标腿产生的线形和角冲量（合成水平反作用力[RFh]、RFh角和力臂）进行了量化，并在组内和球员体内进行了比较（α = 0.05）。由后腿和目标腿产生的净角冲量对司机来说比6号铁杆更大。用于调节球杆之间产生角冲量的机制因球员而异，需要双腿之间的协调。增加的净角冲量与驱动器涉及的目标腿RFh增加。后腿RFh角在杆间保持不变，而靶腿RFh则与靶线更加一致。垂直于目标线的净线性脉冲保持在零附近，保持平衡，而沿目标线的净线性脉冲的幅度减小。这些结果表明，在整个任务中保持平衡的同时，通过协调后腿和目标腿的力产生来调节球杆之间的净角冲量。
Our aim was to determine how skilled players regulate linear and angular impulse while maintaining balance during the golf swing. Eleven highly-skilled golf players performed swings with a 6-iron and driver. Components contributing to linear and angular impulse generated by the rear and target legs (resultant horizontal reaction force [RFh], RFh-angle, and moment arm) were quantified and compared across the group and within a player (α = .05). Net angular impulse generated by both the rear and target legs was greater for the driver than the 6-iron. Mechanisms used to regulate angular impulse generation between clubs varied across players and required coordination between the legs. Increases in net angular impulse with a driver involved increases in target leg RFh. Rear leg RFh-angle was maintained between clubs whereas target leg RFh became more aligned with the target line. Net linear impulse perpendicular to the target line remained near zero, preserving balance, while net linear impulse along the target line decreased in magnitude. These results indicate that the net angular impulse was regulated between clubs by coordinating force generation of the rear and target legs while sustaining balance throughout the task.
