Biomechanical analysis of front crawl arm stroke and leg kick by Tachograph measuring system

Abstract

In our case study contribution we will present the results of crawl technique measurements with the tachograph measuring method, where we focus on analysing the crawl arms stroke and legs kick. This research aims to present a biomechanical analysis of the crawl legs kick (range, position of legs the angle of kick, frequency, depth of kick etc.) and how the measured parameters influence the efficiency and speed of crawl legs. Another aim is to present a biomechanical analysis of the crawl arm angles and frequency and their impact on the speed and efficiency of crawl arms swimming techniques. Measurements were performed with six racing swimmers of the Czech national swimming team. A partial aim is also provid ing information on further developments in measuring techniques with accelerometers at the Brno University of Technology (BUT).In our case study contribution we will present the results of crawl technique measurements with the tachograph measuring method, where we focus on analysing the crawl arms stroke and legs kick.
