Original Abstract

The results of the researches aimed to assess the impact of flutter-kicking (FK) and swimming with the arms only (SAO) on front crawl swimming (FCS) speeds often differ in their results. They agree with the fact that FK is an important part of FCS, but they differ in the proportion at propulsion forces of swimming and the impact of speed on swimming. With the help of the Tachograph measurement system, we verified the possibility of evaluating their relation on the sample of junior category male swimmers. For our evaluation, we have chosen data of 10 swimmers who were at the age of 16 years at the time of measurements. We used the Tachograph measuring system. The swimmers were asked to swim 50 metres, initially only with the help of FK, subsequently using their arms only, and finally FCS. We used data from the first 25 meters of the track to eliminate the effect of push off and turn. At the measured section swimmers reached mean speed of 1,637 ± 0,079 m·s-1 during swimming with FCS, it was 1,399 ± 0,0603 m·s-1 when they SAO, and with FK their mean speed was 1,082 ± 0,067 m·s-1. We found out that swimming velocity when moving without FK is lower by 0,238 m·s-1 ± 0,049 m·s-1 compared to FCS. We focused on the relation between the speed of front crawl swimming with either the arms only or flutter-kicking. The results of our measurements showed that front crawl swimming speed highly correlates with swimming with the arms only (r = 0.83). We did not find any statistically significant relation between the results of flutter-kicking and front crawl swimming (r = 0.15). However, flutter-kicking contributes to higher speed during front crawl swimming at least by reducing the drag forces of water of the swimmer because the measured speed of front crawl swimming is higher than the swimming speed reached with the arms only.
