Abstract

The aim of this paper was to investigate, whether it is possible to objectively evaluate the relationship between three different phases of 100 m sprint running. Following correlation analyses from six major athletics championships, a linear regression based scoring system was created for the acceleration, maximum velocity and velocity maintenance phases. The scoring system can be used for athletes from international level down to moderate national level. Tests for two female juniors showed that the maximum velocity phase was the weakest part of their performance. Therefore, recommendations can be made to coaches for changes to be made in training. This strategy has already resulted in improved balance between different phases for a specific athlete. Current studies are expanding the analysis into the area of individual running gait variables.
