<italic /> <bold> Background: </bold>The purpose of the study was to investigate whether, in addition to an expected increasein anaerobic endurance, aerobic endurance of disabled swimmers would alsoimprove in a special preparation sub-period. Furthermore, decision was made to examinewhether the applied tests prove sufficiently sensitive for swimmers with disabilitiesas well.
<bold>Material/Methods: </bold>The study included 12 disabled swimmers from a section of the Polish Sports Associationfor 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 toestimate anaerobic endurance. For all analyzed parameters the median, first (Q1)and third (Q3) quartiles were calculated. To determine the significance of differencesbetween the results obtained in the preliminary and the control test, the nonparametricWilcoxon test for dependent samples was used. Statistical significance was consideredat p ≤ 0.05.
<bold>Results: </bold>Total distance median in the T-30 test (DST1 = 1575.5 m vs DST2 = 1650 m) improvedin a statistically significant way (p = 0.02). Analyzing the results obtained inthe entire group of athletes in the 6x50 m test, for each single section of 50 m, it wasobserved that the swimming time was significantly shorter during the second study(p < 0.05) but the first section of 50 meters.
<bold>Conclusions: </bold>In a sub-period of special preparation both aerobic and anaerobic endurance of disabledswimmers improved. A more significant improvement was observed in termsof anaerobic endurance, as it occurred for all swimmers. The T-30 and 6x50 m testsproved to be a sensitive tool for assessing aerobic and anaerobic endurance ofswimmers with disabilities.
