Background: The purpose of the study was to investigate whether, in addition to an expected increase in anaerobic endurance, aerobic endurance of disabled swimmers would also improve in a special preparation sub-period. Furthermore, decision was made to examine whether the applied tests prove sufficiently sensitive for swimmers with disabilities as well.
Material/Methods: The study included 12 disabled swimmers from a section of the Polish Sports Association for the Disabled “START” Wroclaw. Two standardized tests were used. The T-30 test was used to evaluate aerobic endurance and the 6x50 m test was applied to
estimate anaerobic endurance. For all analyzed parameters the median, first (Q1) and third (Q3) quartiles were calculated. To determine the significance of differences between the results obtained in the preliminary and the control test, the nonparametric Wilcoxon test for dependent samples was used. Statistical significance was considered at p ≤ 0.05.
Results: Total distance median in the T-30 test (DST1 = 1575.5 m vs DST2 = 1650 m) improved in a statistically significant way (p = 0.02). Analyzing the results obtained in the entire group of athletes in the 6x50 m test, for each single section of 50 m, it was
observed that the swimming time was significantly shorter during the second study (p < 0.05) but the first section of 50 meters.
Conclusions: In a sub-period of special preparation both aerobic and anaerobic endurance of disabled swimmers improved. A more significant improvement was observed in terms of anaerobic endurance, as it occurred for all swimmers. The T-30 and 6x50 m tests
proved to be a sensitive tool for assessing aerobic and anaerobic endurance of swimmers with disabilities.
