| 中文摘要: |
| 采用文献综述法，结合短跑数学模型研究的发展过程，将考虑空气阻力对短跑成绩影响的数学模型分为动力学模型和能量模型两大类，对模型的建立基础及应用结果进行比较，主要比较不同风速和海拔高度对100 m跑成绩的影响，分析不同模型结果差异的原因，为短跑的数学建模和短跑成绩的标准化提供参考。 |
| 英文摘要: |
| By the method of literature study and based on the research development of sprint mathematical model, the article divides the mathematical model, which takes the effect of air resistance on performance into account, into two models of dynamic model and energy model. It compares the foundation of the model to the application result. It analyzes the effects of different wind speed on the result of 100m sprint and the cause of difference between the application of different models. It tries to provide reference for the establishment of sprint mathematical model and the standardization of sprint performance. |
