Resumen
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). 19 3 171 175 Hoffmam, J.R., Maresh, C.M., Physiology of basketball (2000) Exercise and Sport Science, pp. 733-744. , Philadelphia, PA, Lippincott Williams & Wilkins Lamas, L., Especificidade do treinamento no basquetebol: Fatores energéticos e neuromusculares (2006) Rev Mackenzie De Educação Física E Esporte, 5, pp. 93-106 Abdelkrim, N., El Fazaa, S., El Ati, J., Time-motion analysis and physiological data of elite under-19-year-old basketball players during competition (2007) Br J Sports Med, 41, pp. 69-75 Rodriguez-Alonso, M., Fernandez-Garcia, B., Perez-Landaluce, J., Terrados, N., Blood lactate and heart rate during national and international women's basketball (2003) J Sports Med Phys Fitness, 43, pp. 432-436 Laplaud, D., Hug, F., Menier, R., Training-induced changes in aerobic aptitudes of professional basketball players (2004) Int J Sports Med, 25, pp. 103-108 Ben Abdelkrim, N., Castagna, C., Jabri, I., Battikh, T., El Fazaa, S., El Ati, J., Activity profile and physiological requirements of junior elite basketball players in relation to aerobic-anaerobic fitness (2010) J Strength Cond Res, 24, pp. 2330-2342 Monod, H., Scherrer, J., The work capacity of a synergic muscular group (1965) Ergonomics, 8, pp. 329-338 Tegtbur, U., Busse, M.W., Braumann, K.M., Estimation of an individual equilibrium between lactate production and catabolism during exercise (1993) Med Sci Sports Exerc, 25, pp. 620-627 Zacharogiannis, E., Peradisis, G., Tziortzis, S., An evaluation of tests of anaerobic power and capacity (2004) Med Sci Sports Exerc, 36, pp. 116-123 Zagatto, A.M., Beck, W.R., Gobatto, C.A., Validity of the running anaerobic sprint test for assessing anaerobic power and predicting short-distance performances (2009) J Strenght Cond Res, 23, pp. 1820-1827 Wakayoshi, K., Ilkuta, K., Yoshida, T., Udo, M., Harada, T., Moritanii, T., Determination and validity of critical velocity as na index of swimming performance in the competitive swimmer (1992) Eur J Appl Physiol, 64, pp. 153-157 Almeida, P.A.S., Ferreira, G.R., Morais, D.C., Barbosa, E.S., Cardoso, A.T., Rocha, C.C.D., Comportamento dos parâmetros de controle de treinamento aeróbio durante testes de campo (2008) Fitness Perfor J, 7, pp. 406-412 Papoti, M., Zagatto, A.M., Mendes, O.C., Gobatto, C.A., Utilização de métodos invasivo e não invasivo na predição das performances aeróbia e anaeróbia em nadadores de nível nacional (2005) Rev Port Cien Desp, 5, pp. 7-14 Ribeiro, L.F.P., Gonçalves, C.G.S., Kater, D.P., Lima, M.C.S., Gobatto, C.A., Influence of recovery manipulation after hyperlactemia induction on the lactate minimum intensity (2009) Eur J Appl Physiol, 2, pp. 159-165 Pringle, J.S.M., Jones, A.M., Maximal lactate steady state, critical power and EMG during cycling (2002) Eur J Appl Physiol, 88, pp. 214-226 Housh, D.J., Housh, T.J., Bauge, S.M.A., A methodological consideration for determination of critical power and anaerobic work capacity (1990) Res Q Exerc Sport, 61, pp. 406-409 Simões, H.G., Denadai, B.S., Baldissera, V., Hill, D.W., Campbell, C.S.G., Relationship and significance of lactate minimum, critical velocity, heart rate deflection and 3000 m track-tests for running (2005) J Sports Med Phys Fitness, 45, pp. 441-451 Andrade, V.C., (2011), Métodos de velocidade crítca, lactato mínimo e RAST na determinação de parâmetros aeróbios e anaeróbios de corredores: análises transversais e longitudinais [dissertação de mestrado], Piracicaba, Universidade Metodista de Piracicaba -
