Porovnání závodní rychlosti plaveckého způsobu kraul a rychlosti dosažené během intervalů bez vlivu startu a obrátek
Comparison of the racing speed of front crawl swimming technique and the speed achieved during intervals without being affected the start and the turns

Summary/Abstract: The race at 50 meters in freestyle swimming technique can be divided into four main phases -start, swimming at the surface, turn, and finish. With the usage of our measuring system called Tachograph, we mainly analyse the speed of swimming at the surface. Measuring principle does not allow accurate measurement of the speed after starts and turns, for that reason we evaluate the particular sections without the influence of the start and finish. We focused on the evaluation of the ratio of the measured mean swimming speed measured by the system Tachograph with the results of the current best racing performance from the 50 metre distance. For comparison we have processed the results of swimmers who participated in the semi-finals of 2010 European Championship. Our goal was to establish which results of the swimmers measured by Tachograph are at a sufficient level. The objective of the work has been accomplished with the help of statistical methods. Furthermore, we have ascertained that our recorded results differ from the results of elite swimmers whose results have been gained from the evaluation of the sections of swimming at the European Championship. We assume that the race results of our measured swimmers will differ as well. The error may be caused not only by the lack of motivation of the swimmers but also due to the constraints that our measurement system causes.
