ADAPTATION OF INVASIVE AND NON-INVASIVE PROTOCOLS TO AEROBIC AND ANAEROBIC SPECIFIC EVALUATION IN FEMALE BASKETBALL PLAYERS

Objective: The aim of the study was to adapt the critical velocity (CV), RAST test and lactate minimum (LM) to evaluation of female basketball players. Methods: Twelve well-trained female basketball players (19 ± 1yrs) were submitted to four running intensities (10 14 km/h) at shuttle exercise until exhaustion, applied on alternate days. The linear model ‘velocity vs. 1/tlim’ was adopted to determine the aerobic (CV) and anaerobic (ARC) parameters. The lactate minimum test consisted of two phases: 1) hyperlactatemia induction using the RAST test and 2) incremental test composed of five shuttle run (20-m) at 7, 8, 9, 10, and 12 km/h. Blood samples were collected at the end of each stage. Results: The velocity (vLM) and blood lactate concentrations at LM were obtained by two polynomial adjustments: lactate vs. intensity (LM1) and lactate vs. time (LM2). One-way ANOVA, Student’s t-test and Pearson correlation were used for statistical analysis. The CV was obtained at 10.3 ± 0.2 km/h and the ARC estimated at 73.0 ± 3.4 m. The RAST was capable to induce hyperlactatemia and to determine the Pmax (3.6 ±0.2 W/kg), Pmean (2.8 ± 0.1 W/kg), Pmin (2.3 ± 0.1 W/kg) and FI (30±3%). The vLM1 and vLM2 were obtained, respectively, at 9.47 ±0.13 km/h and 9.8 ±0.13 km/h, and CV was higher than vLM1. Conclusion: The results suggest that the non-invasive model can be used to determine the aerobic and anaerobic parameters. Furthermore, the LM test adapted to basketball using RAST and progressive phase was effective to evaluate female athletes considering the specificity of modality, with high success rates observed in polynomial adjustment ‘lactate vs. time’ (LM2).
