※ 引述《rr444 (earth scrap)》之铭言： : ※ 引述《cmvct723d (working on)》之铭言： : : 绿兄说的是真的 : : 我学球时的教练学长也是教我们用劈的 : : 球棒由耳朵旁边往胸口正前方用力挥出 : correct, they teach you a up-to-down swing : because we want balls having : a back-spin effect afte hit by this way that makes balls go : far and far. : instead, by using down-to-up swing, the balls after hit with : a fore-spin effect (like tennis or table tennis balls), : they sink quickly. in other words, they are impossible : out of the ballpark. 异议~~~ 我认为球的back/fore spin并不是因为由上往下挥击或着是由下往上挥击所造成的 主要原因是击球点的问题 因为棒球与球棒都相当坚硬 互相接触的时间跟网球乒乓球差太多了 几乎是碰撞的下一瞬间就离开了 如果照你叙述所言 打者用up cut来挥球球不就是往前旋? 高尔夫击球不就是往前旋? 并没有这种现象阿 = = 击球点再心球的下方就会造成反旋 击球点在球心的上方就是正旋 这样比较符合现实的叙述 跟你怎麽挥棒是没有正相关的 : : 甚至会叫我们站在柱子前方30CM，柱子对准身体中线 : : 然後挥棒动作要不能让棒子碰到柱子 : : 他们认为这样的动作就是不倒棒 : : 还会教我们用Power V这个动作去当作击球点的动作 : : 也就是说 : : 。 : : )>--== : : ) 躯体正面 : : > 伸直的双手 : : --== 球棒 : : 像这样的动作去击球 : : 想打进界内身体就不能开太多 : : 主要是双手往胸前伸直去合球 : : 但是绿兄并没有说这是个正确的动作 : : R4兄想像不到的训练方法的确是存在的 : : 我思考过这个问题 : : 应该是台湾棒坛早期发展时看图说故事 : : 看到强打者的图片相片有POWER V的动作 : : 例如 : : http://daryl1947.mlblogs.com/photos/hall_of_fame/hall4.jpg : : http://cache.deadspin.com/images/2006/05/bonds714.jpg : : http://www.cardsclubhouse.com/downloads/bin/pujols-2.jpg : : 但是却倒果为因 : : 认为POWER V就是contact动作中最重要的一环 : : 但是事实上power v只是身体用力往正面旋转送出球棒後双手被球棒惯性拉直 : : 也就是followthrough的收尾动作 : : 这可以说是先人的错误遗留下来的错误观念与教学 : you might make an excellent point but i am just too : stupid to understand by your description. if you can : provide me a pic of your training method, i think i can : have more ideas and make correct comments. : but in your description, i do find a toboo that most players : try to avoid, but your teachers ask you to practice it - : to straight your arms quickly during the motion of swing ( i might : make a misjudgement because of too less information that : you provide or that i can understand.) : like "allen65535" pointing out in the "pushs", hitter's arms can't : be straight before hitting the ball (maybe ok while hitting the balls). : but to my standard, the best way is what "allen65535" said, " straight : you arms in nanoseconds after balls are contacting the bats.", which : generate the maximum bat speed during the ball is hit. : do an experiment, after your straight your arms, unless : you still can rotate your waist, the bat speed can't : increase anymore and most of the time, it start decreasing. --
