Resumo: | Few studies allow usto verify which physiological responses are associated with performance in anational elite cycling group. Therefore, this study aimed to determine and correlate various physiological and aerobic indices with performance in 4 and 20 km time trials in high-level cyclists. The sample consisted of 14 male professional cyclists of the national elite group (28.5 ± 4.7 years old, 73.47 ± 8.29 kg, 176 ± 6.76cm), who performed a progressive test in laboratory to determine maximal oxygen consumption (VO2max: 62.23 ± 8.28 ml•kg-1•min-1), intensity relative to VO2max (iVO2max: 500.83 ± 58.65w), movement economy (EM: 0.1166 ± 0.0362 ml•kg•min•w-1), and the first and second ventilatory threshold (LV1: 348.21 ±43.26 w; LV2: 417.86 ± 60.79 w, respectively). They also performed two time trial performance tests of 4 and 20km. For the correlation between physiological indices and trial performance, Pearson correlation coefficient (p< 0.05) was used. No correlation was found between the physiological indices (VO2max absolute and relative, iVO2max, EM, LV1 and LV2) and performance in 4 km (r= 0.38; 0.16; -0.33; 0.20; -0.50; -0.20, respectively) and 20 km (r= 0.24; 0.01; -0.13; -0.12; -0.48; -0.19, respectively) time trialin high level athletes. These results suggest that these variables are not able to explain the performance in time trials in the respective lengths, probably due to the subjects’ homogeneity. |

Portanto, o objetivo do presente estudo foi determinar e relacionar diferentes índices fisiológicos aeróbios com o desempenho em testes contra relógio de 4 e 20km em ciclistas de alto nível. A amostra foi composta por 14 ciclistas profissionais de elite nacional do sexo masculino (28,5 ± 4,7 anos, 73,47 ± 8,29 kg, 176 ± 6,76 cm),que realizaram um teste progressivo em laboratório para a determinação do consumo máximo de oxigênio (VO2max: 62,23 ± 8,28 ml·kg·min-1), intensidade relativa ao VO2max (iVO2max: 500,83 ± 58,65 w), economia de movimento (EM:0,1166 ± 0,0362 ml·kg·min·w-1) e 1º e 2º limiares ventilatórios (LV1: 348,21 ±43,26 w; LV2: 417,86 ± 60,79 w, respectivamente). Também foram submetidos a duas provas de 4 e 20km contra relógio. Para correlação entre os índices fisiológicos e desempenho, foi utilizado o coeficiente de correlação de Pearson (p< 0,05). Não foi encontrada correlação entre os índices fisiológicos (VO2max absoluto e relativo, iVO-2max, EM, LV1 e LV2) e o desempenho de 4km (r=0.38; 0.16; -0.33; 0.20; -0.50; -0.20, respectivamente) e 20km (r= 0.24; 0.01;-0.13; -0.12; -0.48; -0.19, respectivamente) contra relógio em atletas de altonível. Estes resultados sugerem que tais variáveis não apresentam capacidade de explicar o desempenho em provas de contra relógio nas respectivas distâncias, provavelmente, devido à homogeneidade entre os sujeitos.Universidade Federal de Santa Catarina.
