运用文献资料、比较分析法、举证分析等方法,根据物理学中的v-t(速度-时间)曲线原理,对4×100m接力中交接棒时段的v-t曲线特征进行整理归纳并分类,提出4种不同的交接棒的v-t曲线特征,并绘出了4×100m接力赛中不同交接棒情况下的v-t曲线,经物理学公式计算,得出其前3棒队员在交接棒时段的速度都达到百米途中跑速度的96%以上。研究结果表明,理想的4×100m接力赛的v-t曲线应是一条高而平的运动v-t直线(除起跑阶段外)。此外,结合理想的v-t曲线特征提出了上挑式的交接棒形式和双重信息传递的形式能保证交接棒时段的稳定且连续的高速度,为该项目教练员和运动员在今后的训练和比赛提供积极的理论与实践参考。
According to the vt (velocity-time) curve principle in physics, the vt curve characteristics of 4 × 100m relay during the transfer bar period are summarized and classified according to the methods of literature, comparative analysis and evidence analysis. Four different Vt curve characteristics of the transfer of the bar and draw 4v 100m Relay in the case of different transfer rods vt curve calculated by the physical formula obtained the first three bats players in the transfer of the bar time speed of 100 meters On the way to run more than 96% speed. The results show that the ideal 4 × 100m relay race v-t curve should be a high and flat movement v-t line (except the start-up phase). In addition, combining the ideal vt curve characteristics, the pick-up pick-up form and double information transmission form can guarantee the stable and continuous high speed of the pick-up time, and provide the coaches and athletes with the training and competition in the future Positive theory and practice reference.
