                                            上杆应注意杆头位置

                                             


                                            1. 宁波高尔夫|宁波住宿|宁波酒店|宁波场地|宁波草坪|宁波场地|宁波会议|宁波度假村
                                              高尔夫挥杆动作的全部内容包括杆后摆或后摆杆(take back)-上挥杆(back swing)-挥杆顶点(top of swing ,top swing)-下挥杆(down swing)-冲击球或触球(impact)-顺势动作(follow througnh)-结束动作(finish)几大组成部分。

                                                一些专家认为,高尔夫的挥杆技术是一种围绕纵轴的旋转运动,身体基本上没有向?#19968;?#21521;左的横向移动及向前或向后的俯仰动作,即使有也只是一种感觉而已。要认为这个纵轴从头部通过身体中心,以此轴为中心,用两臂、两手挥动球杆,肩部也做必要的充分回旋,在假想的?#39184;?#20013;转动肩部、腰和下肢。从后摆杆开始到最后完成结束动作都以这个轴为中心转动。

                                                如前所述,挥杆的目的不单纯是击球,还要使球正确地飞?#23567;?#29699;能否正确飞行,最终取决于球杆头的杆面冲击球时是否正对着球的飞行方向,而冲击球时球杆面的状态又受挥杆轨迹及挥杆轨迹中的每一瞬间球杆面所处状态的制约。

                                                所谓挥杆轨迹是指挥杆过程中杆头通过的路线,这个轨迹应该是一个较为均匀的大圆弧,如果把球杆的杆身扫过的路线连接起来就形成一个倾斜的平面,这个平面叫做挥杆面(swing plane)。挥杆轨迹的大小及挥杆面的倾斜度与所使用的球杆有关,使用长杆时轨迹的圆弧大,挥杆面的斜度也大,反之则小。要保持挥杆轨迹和挥杆面的均匀性和正确性,是保证冲击球时杆面正确状态的先决条件之一。注意挥杆面应该是一个均匀的圆形,决不要描成“8”?#20013;巍?/div>

                                                在挥杆过程中杆面的正确状态应该是:

                                                在最初后摆杆时杆面正对目标,随着球杆被逐渐上挥,杆面逐渐打开,朝向身体正前方,至挥杆顶点时,朝向身体前上方,后倾大约四十五度,在下挥杆过程中?#31181;?#28176;还原,冲击球时正对目标方向。

                                                1.后摆杆(take back)

                                                是指将杆头从击球准备时的状态开始向球的后上方摆动的动作,从开始启动到进入屈腕动作(cock)为止。后摆杆是上挥杆的起始部分。

                                                使左臂与球杆成为一个整体,不要屈腕屈肘,保持两臂与肩构成的三角形,左肩、左臂和左手与球杆形成一体,以左肩?#26469;?#24102;动臂、手、球杆,将球杆杆头慢慢向球的飞行方向正后方引摆三十厘米左右。在此过程中?#27426;?#35201;保持杆面始终正对球的飞行方向,也就是说,从杆头启动到杆头向球的后方摆动至右足尖前方,两臂与球杆?#21248;?#20445;持击球准备时的关系状态,杆头的底面几乎贴着地面水平地向后运动。后摆杆的关键是慢而直。所谓慢就是指杆头的向后运动要缓慢,这样有利于整个上挥杆的节奏;所谓直是指球杆的杆头要直线向后摆动,而且杆面保持正对球。在两手到达右膝的前上方处之前,因为球杆和两臂、身体一起同步运动,所以球杆的握柄尾端要始终指向脐部,这也是检查后摆杆动作是否正确的简便方法之一。

                                                2.上挥杆(back swing)

                                                从挥杆动作的整体来看,后摆杆和上挥杆之间并没有区间界限,也没有任何停顿,后摆杆是上挥杆的起始,上挥杆是后摆杆的?#26377;?#29978;至可以说后摆杆就是上挥杆的一部分。

                                                继后摆杆之后,继续保持肩与两臂构成的三角形,以杆头带动两臂及左肩向右转动,在两手到达右腰部高度时,左臂如同向右上方伸出一样继续上举。左腋夹住,右臂的上臂基本保持固定,右腋夹住,肘部随左臂的上举徐徐弯曲。左肩继续在臂的带动下向右转动,同时带动左腰和左髋也向右扭转。在上体和髋的转动作用下,左?#35748;?#20869;旋扭,左膝内扣,大腿内侧肌肉被拉紧。右腿在扭转力的作用下,?#21248;?#20445;持内扣,维持两膝间的距离,以阻抗右腿也被?#35748;?#21491;扭转的趋势,所以右腿如同弹簧般被充分扭转压紧。右足内侧承担大部分体重,其余部分由右足前脚掌内侧承担。

                                                在上挥杆过程中,头颈部与脊柱保持一体,可以假定身体扭转运动的中心轴即是从头顶部穿过颈、?#22330;?#33136;,最后到达骶尾部的。两眼注视球,头颈部固定,保持正?#20445;?#19981;要有任何左右摇摆或扭转,左肩最终回旋至下颏的下?#20581;?/div>

                                                后摆杆以后,两臂?#21248;挥?#29699;杆保持同步运动,左臂伸?#20445;?#23613;量保持较大的上挥杆幅度。左手手?#21507;?#25163;臂的运动过程中,逐渐由朝向球的飞行方向转为朝向身体前方,球杆面也逐渐打开,在两手到达腰部时,左手手背基本正对前方,此时杆头继续领?#21462;?#24038;臂带动左肩充分转动,左手拇指指腹支住球杆握柄,左手向拇指方向屈曲,完成屈腕动作(cock)。保持手腕的正?#20445;?#24038;手手背与左前臂位于同一平面上。右肩也有意识地参与上体回旋运动,以使身体转动得更加充分,肩部转动九十度左右,腰部转动四十五度左右,两臂充分上举,两手到达右耳得位置,左踵稍提起,左膝在扭转作用下靠向右膝,左肩指向球的右侧,进入挥杆顶点。

                                                在上挥杆过程中,左臂要一直保持击球准备时的状态,肘部不要弯曲,手腕要伸直。如果肘部屈曲,就会使挥杆的幅度变小,这样而且很可能导致左肩转动不足,使击球的冲击力减小;手腕若不伸?#20445;?#20250;影响挥杆的轨迹,从而造成各种各样的失误球。屈肘屈腕是一般初学者最容易出现的错误,需要特别注意。

                                                另外保持身体左侧的主导作用也很重要,如果右臂和右手过于积极,就会造成球杆杆面过早打开,左肩转动不足并下沉,右腋张开,左腕弯曲等一系列错误,而这些都是导致球向左旋的原因。所以初学者?#27426;?#22312;开始学习时就注意这些问题。
