一个好的上杆决定了下杆击球的准确度和完善性。因为,对于职业球手来讲,一个上杆的动作大约用时0.90秒;而作为一个单差点的球手,下杆动作会使球达到100英里/小时(职业球手能达到135英里/小时以上);此后,杆头触球的时间也仅有1/5秒(职业球手为1/7秒)。从这样的时间比对来看,一个完整的全挥杆动作中,下杆和触球的时间太短了,只有上杆是相对用时最长的,也是有时间去调整动作的,因此,上杆的好坏对下杆至关重要。 A good upper pole determines the accuracy and perfection of the next shot. Because for a professional golfer, a top shot takes about 0.90 seconds and a single shot player down to 100 miles per hour (professional golfers can reach more than 135 mph ); Since then, the club touch the ball time is only 1/5 seconds (professional player for 1/7 seconds). From such a time comparison point of view, a complete full swing action, the lower bar and touch the ball too short time, only the upper bar is relatively the longest time, there is time to adjust the action, therefore, on The quality of the bar is crucial to the bar.
