Resumo: | Exhaustive running at maximal oxygen uptake velocity (vVO2max) can alter running kinematic parameters and increase energy cost along the time. The aims of the present study were to compare characteristics of ankle and knee kinematics during running at vVO2max and to verify the relationship between changes in kinematic variables and time limit (Tlim). Eleven male volunteers, recreational players of team sports, performed an incremental running test until volitional exhaustion to determine vVO2max and a constant velocity test at vVO2max. Subjects were filmed continuously from the left sagittal plane at 210 Hz for further kinematic analysis. The maximal plantar flexion during swing (p<0.01) was the only variable that increased significantly from beginning to end of the run. Increase in ankle angle at contact was the only variable related to Tlim (r=0.64; p=0.035) and explained 34% of the performance in the test. These findings suggest that the individuals under study maintained a stable running style at vVO2max and that increase in plantar flexion explained the performance in this test when it was applied in non-runners. |

A corrida realizada na velocidade do consumo máximo de oxigênio (vVO2máx) pode ocasionar modificações nos parâmetros cinemáticos e assim, aumentar o custo energético ao longo do tempo.O objetivo do presente estudo foi analisar características cinemáticas da articulação do tornozelo e joelho durante a corrida na vVO2máx e a relação entre modificações cinemáticas e o tempo limite na vVO2máx(Tlim). Onze voluntários ativos fisicamente foram submetidos a um teste incremental de corrida para determinar a vVO2máx e posteriormente, a um teste de velocidade constante na vVO2máx. As variáveis cinemáticas foram adquiridas através de filmagem bidimensional a 210Hz no plano sagital esquerdo, no estágio inicial e final da corrida.De todas as variáveis angulares analisadas, a máxima plantiflexão no balanço (p<0.01) foi a única que aumentou significativamente entre o início e o final da corrida. O aumento no ângulo do tornozelo no contato foi correlacionado ao Tlim (r=0,64; p=0,035) e explicou 34% do desempenho no teste. Esses achados sugerem que os sujeitos mantêm um estilo de corrida relativamente estável na vVO2máx e que o aumento da plantiflexão no contato foi capaz de explicar o desempenho neste teste entre sujeitos não corredores.Universidade Federal de Santa Catarina.
