Abstract |
PURPOSE The purpose of this study was to investigate effect of spatio-temporal variables related to the standing start on short-distance time trial of female athletes by using videos having been executed in cycling world championship and track cycling world cup game. METHODS 104 competition videos were analyzed from 2013 to 2016. In order to compare differences among groups, upper group A, middle group B, lower group C were divided by 1 lap time. Standing distance, standing time, average speed to the point of sitting time, average speed before and after 15m sitting time and pearson’s correlation coefficient were analyzed in each sectio1n. RESULTS In the fastest group of 1 lap records, standing distance was the most longest and average speeds in each section were the most fastest compared to other groups.
And negative correlation showed between average speed and 1 lap time. CONCLUSIONS When standing distance to the sitting point was long and average speeds in each section were fast, we confirmed that 1 lap time was fast. It is necessary to sit at full speed using maximum power before sitting and to combine training to increase the overall average speed during long section as well as to increase speed during short section. |
