Relations Between the World Record in Running at 100m and Altitude and Wind Speed

Abstract

A sprint is a dynamic and explosive cyclic movement determined by an ability to accelerate, a size of maximum speed and an ability to maintain the speed in relation to an onset of fatigue, so many factors can affect a sprint result, whether they are of an internal nature - motivation, technique, readiness and fatigue, or external - wind direction and strength, altitude, temperature, texture and hardness of substrate. The goal of the research was to determine the connection between altitude and wind speed with the achieved results in the 100m running for men, which are categorized as world records (manually and electronically measured results) and to predict the results depending on altitude and wind speed, and to determine the best achieved times in years in which no world records were recorded and their connection with altitude and wind speed, and to determine the periods of stagnation of the results, in order to determine, after specifying those periods, whether the altitude of the cities where the records were achieved and the wind speed were possible causes of the stagnation measured during the achievement of the results, which would all help to create more optimal conditions for achieving a better result and setting a new record in the 100m running discipline. After all the analyses, that is, by observing the results of recognized world records measured manually and electronically, it can be concluded that the wind speed had a connection and prediction in the achievement of the world record in the period from 1912 to 1968 when the results were measured manually (if the wind increased by 1 ms-1 the result improved by 0.08 sec), while the altitude value had a connection and prediction in the achievement of world records in the period from 1968 to 2009 when the results were recorded by electronic measurement (if the altitude increased by 1m the result improved by 0.00008 sec).
