摘要
高杆抛绣球是少数民族传统体育项目之一,兼社交娱乐和健身于一体。正确掌握高杆抛绣球受力和运动情况,有利于在比赛中取得更好的成绩。结合比赛规则,运用物理力学手段,从抛出位置、抛射角度和抛射初速度等三方面分析抛绣球的受力和运动情况,并得出结论:运动员所站的最佳位置应该在投球控制线的中点处;绣球的最佳抛出角度为α=65°;最佳初速度为V0=16.3m/s。
The high-pole throwing Hydrangea is one of traditional ethnic sports, and social recreation and fitness in one. Cor-rectly grasping the force and movement of throwing Hydrangea will help achieve better results. Combined with competition rules and the use of physical and mechanical means, from the thrown position, angle and projection angle and initial speed, this paper analyzes the force and movement of throwing Hydrangea and concludes that the best position is the midpoint; the best angle is ; the best ini-tial speed is.
