Abstract:
It is well known that wind and altitude can affect the performance of long-jumpers. In this paper we show that according to our model the maximal allowable tail-wind 2m/s at sea level will improve the distance of a jump of the same athlete by 14-18 cm. Altitude also will improve the performance on a still day by 4-5 cm for each 1000 m. It can be also calculated that a 5 °C increase of temperature is equivalent to an increase of altitude by 150 m. It appears that wind and altitude have a significant effect mainly because of changes in the take-off values. The faster the athlete runs, the greater the take-off velocity. We also provide a long jump computer simulator for modeling the trajectory of the sportsman’s center of gravity. Our program is supposed to help coaches and sportsmen estimate the contribution of atmospheric effects into the final result and take full advantage of the sportsman’s potential.
