摘要：

Track aspect ratio is defined as the percentage of lap length devoted to turns on an oval running track. Equations based on experiments are developed to model a composite runner with a specified top speed, during an acceleration phase in the straightaways and a centripetal phase in the turns. We calculate velocity deficits for several common track sizes over the range of aspect ratios and predict that, under our assumptions, a perfect circle is the optimal track shape. © 1990.
