蓄力偏晚
Also known as: 延迟蓄力, 启动迟缓
Definition
蓄力偏晚是指重心转移和双手后引的动作,启动得比来球飞行时间所允许的更晚,留给完成一次完整、平衡挥棒的时间太少。
蓄力是击球员的预备动作——重心稍微后移、双手落到位——必须在挥棒向前启动之前完成。蓄力偏晚会压缩之后的一切:跨步、旋转和棒头路径都必须比平时更快才能勉强按时到达,这通常会以牺牲平衡感和球棒速度为代价。这与刻意追求耐心不同;蓄力偏晚是一种时机上的失误,而不是一种策略。
Example
被来球较高的最高点分散了注意力,击球员把蓄力拖延得太久,不得不匆忙完成跨步和挥棒才勉强把球棒送到球那里,过程中失去了平衡感和球棒速度。
How it shows up on video
A late load shows the hitter's weight-back and hand-set motion beginning noticeably later relative to the pitch's descent than a well-timed swing. This forces the rest of the swing to compress into less time.
Common mistakes
- Getting absorbed in watching the ball's rise and forgetting to begin the load in time
- Confusing "being patient" with delaying the load itself, when patience should apply to the swing trigger, not the preparatory load
- Not recognizing that a higher, longer arc still requires the load to begin on a consistent internal schedule
In SwingVantage Motion Lab
SwingVantage measures the timing of the load's initial weight shift relative to pitch release and flags loads that begin unusually late relative to the pitch's total flight time.
Related terms
- 蓄力蓄力是指在启动挥棒之前,身体重心向后转移、双手卷紧,形成一个预备就绪、蓄势待发的姿势。在慢投垒球中,蓄力必须尽早完成,并在球沿长弧线下坠期间保持住。
- 挥棒过于仓促挥棒过于仓促,是指蓄力和挥棒机制的启动速度超过了来球实际所需要的节奏,通常源于紧张情绪,或是延续自更快来球速度的习惯,结果导致接触偏早、身体失衡。
- 判读弧线时机判读弧线时机是指从投球出手到最高点再到下坠的整个过程中追踪慢投来球的能力,并据此启动挥棒,让棒头恰好在球进入可击打区域时到达。
- 跨步时机跨步时机是指前脚相对于投球在其弧线中所处位置而落地的时刻。面对慢投弧线,前脚应该早早落地——接近最高点附近——同时双手保持后引,由此产生下半身与上半身之间的分离,产生力量。
- 靠后脚击球靠后脚击球是指击球员的重心在接触瞬间依然停留在后腿上,没有向前转移,导致挥棒完全依赖手臂发力,几乎没有旋转力量。
