Measurement of swimming speed with different fins

Abstract

The aim this paper to assess the performance of different types of swimming fins. The sample consisted of ten female swimmers with a mean decimal age 24.73 ± 3.54 years, weight 61.53 ± 5.50 kg. and height 168.30 ± 2.30 cm. Swimmers swam at maximal speed 25m. This test was performed without using fins and using flexible, stiff and fibre fins. The order was randomized and there was a 30 minute break between tests. Maximum speed was determined at three points of the test, beginning, middle and end for every situation. We compared the velocity in different parts for each test (student t test) and between different fins (anova test). The significance level was defined at 95% (P ≤ 0.05). The results show the effect of fatigue on the second part of the test, in all situations. A lower speed when not using fins. The fins are less effective flexible fins. Best performance of the stiff fins in the beginning, also the fastest and best performing was determined with fibre fins in the middle of the test.
