Strocking parameters in top level swimmers with a disability
Résumé
Purpose: The purposes of this study were to analyze velocity (V}, stroke length (SL), and stroke rate (SR) values during the 100-m freestyle competitive events in top !evel male and female swimmers with a disability (DS) according to the international Functional Classification System (FCS) and to compare the resuhs obtained with those of able-bodied swimmers (ABS). Methods: DS (N = 119) and ABS (N = 32} were tested in real competitive conditions during European and French swimming championships in the A finals of the 100-m freestyle. Results: V and SL increased significamly (P < 0.01) according lO the level of ability from dass S3 up to SlO. SL values were significantly different (P < 0.01) between males and females in each class group. On the contrary. SR was not significantly different between genders, becween each class group of FCS, and also with ABS. The major result of this study was that stroke length was related to velocicy whereas stroke rate was not. The · differences in weekly training time between each class of DS were not significantly different and showed that performances seemed to be more related to the various locomotor disabilities than 10 the training status. Conclusions: These findings. which are discusscd, showed that stroke index (S[ = V.SL) could be used as a sensitive criterion to assess the swimmer with a disability in relationship to his classification level.
