Resumo

This study aimed to test the reproducibility of the maximal accumulated oxygen deficit (MAOD) values and VO2-intensity relationship parameters as measured during tethered swimming. 9 swimmers performed an incremental test to determine the maximal aerobic force (MAF), 6 submaximal efforts to develop VO2-intensity relationship, and an exhaustive effort to determine MAOD. The tests were performed twice. The reproducibility of the measurements was tested using intraclass correlation (ICC), typical error (TE) and coefficient of variation (CV). High levels of reproducibility were observed for MAF (TE = 2.6 N; CV = 4.3 %; ICC = 0.98) and VO2-intensity relationship parameters, as intercept (TE = 0.01 L.min(-1); CV = 11.4 %; ICC = 0.97), slope (TE = 0.002 L.min(-1). N-1; CV = 3.1 %; ICC = 0.97) and coefficient of determination (TE = 0.02; CV = 1.8 %; ICC = 0.47). The MAOD values measured during the test (2.9 +/- 1.1 L and 45.3 +/- 14.0 mL. Kg(-1)) and retests (2.9 +/- 1.1 L and 45.2 +/- 12.6 mL. Kg(-1)) were highly correlated (absolute values: ICC = 0.93; relative to body mass values: ICC = 0.89) and presented low values of TE (0.3 L and 4.3 mL. Kg(-1)) and CV (9.5 % for absolute and 9.6 % for relative to body mass values). Thus, we demonstrated the potential use of tethered swimming to assess anaerobic capacity in an aquatic environment.
