旋转推铅球技术是继背向滑步推铅球技术之后出现的另一种投掷技术。进入80年代后在美国尤为盛行,在1985—1986年间全美前10名男子铅球选手中,有7名是采用旋转推铅球技术。当时人们认为旋转投掷技术与滑步投掷技术相比具有以下优势: ·器械的加速路线更长。 ·在投掷圈前部双腿向上用力的条件更为优越。 ·旋转过程使投掷动作更富有节奏感。 ·身材和力量相对较小的选手利用旋转过程较长的加速路线也可以达到较高水平,因而 Rotating Shot Putting is another type of throwing technique that follows the slide-to-shot putter technique. It was particularly prevalent in the United States after entering the 1980s. Of the top 10 men’s shot putters in the United States from 1985 to 1986, seven used turn-put shot techniques. At that time, people thought that rotating throwing technology has the following advantages over sliding throwing technology: · The acceleration route of the instrument is longer. · In the throwing ring in front of his legs upward condition more superior. Rotation makes throwing rhythm more rhythmic. · Players with relatively small stature and strength can also reach a higher level by using a longer course of acceleration, thus
