ABSTRACT
The main goal of this study was to assess the appropriateness of both ergometric and modified hurdles tests for an annual cycle of hurdlers who were working on mastering the 400 m distance. Nine Polish hurdlers (personal best 54.46±2.16 s, age 20.67±1.87 years) were chosen as the research participants. In each of two mastering periods in the research, an ergometric test and a specific test were implemented during a hurdle run. In February, an interval ergometric test (5×6 s) and an interval hurdle test (IHT) were performed. Additionally, in May, a classic Wingate test and a 200 m hurdle run were introduced. With regard to the ergometric tests, we assessed the following measurements maximum power (Pmax) and mean power (P×) reached in five repetitions as well as total work (Wtotal) performed in five attempts. The Mann-Whitney test was used to distinguish between the athletic test results obtained in the preparation period outlined above and those obtained in the first period. Lactate (LA) concentrations were assessed with the Chi-square test. Moreover, Spearman's rank correlation coefficients were used in the analysis. The achieved study results indicate the lack of significant differentiation of the ergometric test parameters (p≥ 0.05). The spatial structure of both specific tests (5×2 H v. 200 m H) was similar given that the first and the second parts of both hurdle races and the number of steps taken were similar. The basic parameters of the ergometric tests did not exhibit any relationship with the recommended record time achieved for the 400 m hurdle run.
RESUMO
O objetivo deste estudo foi avaliar a idoneidade de seleção dos testes ergométricos e testes modificados de corridas com barreiras ao longo do ciclo anual de treinamento dos atletas na distância de 400m. Participaram do estudo nove atletas poloneses (melhor

resultado:

54,46±2,16s, idade 20,67±1.87 anos). Em duas temporadas de treinamento foram realizados dois testes ergométrico e especial (=na corrida com barreiras). Em fevereiro foi efetuado o teste ergonómico em intervalos (95x6s) e o teste com barreiras Rest com intervalos (IHT). Em maio foi efetuado o teste clássico de 30 s Wingate e uma corrida de 200m com barreiras (200mH). Nas corridas com barreiras foram considerados os parâmetros de tempo, potência máxima (Pmax), potência média (Px) e trabalho total (Wtotal). Para avaliar as diferenças entre os resultados dos testes numa temporada foi aplicado o teste de Mann-Whithney. As diferenças de concentração do lactato (LA) foram avaliadas com o teste Chi-square. Na análise foram considerados também os coeficientes de correlação de postos de Spearman. Os resultados dos estudos demostram a ausência de diferenças pertinentes nos parâmetros dos testes ergométricos (p ≥ 0,05). A estrutura espacial de ambos os testes especiais (5x2H vs. 200mH) foi semelhante na primeira e segunda parte de ambas as corridas foi efetuado o número parecido dos passos. Os parâmetros essenciais dos testes ergométricos (Pmax, Px, Wtotal) não demostraram relações importantes com o resultado recorde na corrida de 400m com barreiras. A análise demostrou a possibilidade de utilização seletiva dos testes ergométricos na avaliação do grau de preparação dos atletas para a distância de 400m com barreiras.
