一、影响前抛实心球成绩的因素影响实心球成绩的因素有出手初速度、出手角度及出手高度。其中,出手初速度是最重要的因素。实心球出手初速度主要是由最后用力投掷球的距离和时间决定,用力距离越大,时间越短,则实心球的出手初速度就越大,出手初速度的能力主要取决于学生的身体素质发展水平及掌握正确的投掷实心球技术。实心球的出手角度对投掷成绩也有较大的影响,最佳出手角度,在一定范围内随出手速度的增大而增大,出手角度因不同身体素质的学生而变化,男生可以大一点而女生应小一点。实心球的出手高度对每位 First, the factors that affect the performance before throwing a solid ball The factors that affect the solid ball score are the initial speed, shot angle and shot height. Among them, the initial shot speed is the most important factor. The initial speed of the solid ball shot is mainly determined by the distance and time of the last forcibly throwing the ball. The greater the force distance and the shorter the time, the higher the initial speed of the solid ball shot. The ability of the initial speed of shot mainly depends on the physical quality of the student Level of development and master the correct throw solid ball technology. Solid ball shot angle also have a greater impact on the throwing performance, the best shot angle, with a certain range increases with the increase in speed, shot angle due to different physical changes in students, boys can be bigger and girls Should be smaller. Solid ball shot height for each
