明清捶丸运动的兴衰及其对当代高尔夫运动启示

捶丸运动素有“中国式高尔夫”之称,其兴衰与变迁蕴含着复杂的社会成因,从中探求有益启示,为当代高尔夫发展提供借鉴.采用文献资料等方法,对明清时期捶丸运动的兴盛与衰落脉络进行梳理,探究明清捶丸运动流变的深层原因与当代启示.结论如下:清代统治阶级的娱乐导向是捶丸运动走向衰落的主要原因,该时期民族文化的融合与渗透、社会习俗与社会风气的变迁是其重要原因;当前高尔夫发展背离了正常的发展轨道,其生存与发展的社会环境面临着诸多困难;历史的经验给予我们启示,社会基础和社会需求是高尔夫球发展不可忽视的重要条件,而政府的导向作用对高尔夫的发展起到至关重要的作用.     

基于DBN模型与Kinect数据的高尔夫挥杆重建

人们对高尔夫运动的兴趣在过去的10年间爆发式增长,同时高尔夫球员的数量也显著增加.因此,如何训练一个球员做出适当和准确的挥杆动作已经引起研究者的广泛关注.在此类研究中最重要的步骤是挥杆动作的捕获与重建.至今为止,以Kinect为代表的深度成像设备受其基础条件的限制,其捕获的挥杆运动可能会由于运动中肢体之间的互相遮挡与肢体识别时产生的混乱丧失足够的精确度.为了从肢体互相遮挡并且分辨率较低的深度图像信息中恢复比较精确的运动信息,该文提出一个用于描述人体关节点之间空间关系与关节点动态特性的动态贝叶斯网络(DBN)模型,并基于该模型实现了高尔夫挥杆动作的重建.实验结果表明,该算法能够实现重建精度媲美商用的光学运动捕获系统(OMocap),并且比现有的深度信息修改算法具有更好的性能.     

An occlusion paradigm to assess the importance of the timing of the quiet eye fixation

Abstract

The aim of the study was to explore the significance of the ‘timing’ of the quiet eye (QE), and the relative importance of late (online control) or early (pre-programming) visual information for accuracy. Twenty-seven skilled golfers completed a putting task using an occlusion paradigm with three conditions: early (prior to backswing), late (during putter stroke), and no (control) occlusion of vision. Performance, QE, and kinematic variables relating to the swing were measured. Results revealed that providing only early visual information (occluding late visual information) had a significant detrimental effect on performance and kinematic measures, compared to the control condition (no occlusion), despite QE durations being maintained. Conversely, providing only late visual information (occluding early visual information) was not significantly detrimental to performance or kinematics, with results similar to those in the control condition. These findings imply that the visual information extracted during movement execution – the late proportion of the QE – is critical when golf putting. The results challenge the predominant view that the QE serves only a pre-programming function. We propose that the different proportions of the QE (before and during movement) may serve different functions in supporting accuracy in golf putting.

Braided composite materials for the production of lightweight, high rigidity golf shafts

Braiding is not currently used in the production of golf shafts. The objective of this work was to develop, through a modelling process consisting of altering lamina sequence, a golf shaft, using braided laminas, which would have mass, stiffness and torque comparable to commercially available composite and steel shafts. A 2D conical braided composite model was previously developed and validated to predict elastic constants of braided closed meshed structures. Energy methods were used to calculate the stiffness and torque of shafts using prescribed industry approaches. Shaft mass was calculated based on geometry and density of constitutent materials. Modelled shafts had both braided and unidirectional layers and compared favourably with or were better than commercially available composite and steel shafts in terms of deflection force and twist angle; they had the same weight as composite shafts but were much lighter than steel shafts. If these findings are verified, braided composites would be a viable and effective approach to the design of future golf shafts.
