Objetivo: avaliar a cinemática da corrida durante a prova de 50 metros de 28 escolares do ensino fundamental.
Método: para a avaliação cinemática foram realizadas filmagens no plano sagital, durante a corrida ao longo de todo percurso da prova de 50 metros. Foi mensurado o tempo total do percurso e a cada 5 metros, o comprimento da passada e foram calculadas a frequência de passos e a velocidade. Resultados e considerações finais: não houve diferença na quantidade de passos (p=0,417) e no comprimento da passada (p=0,868) durante os 50
metros entre os sexos. Entretanto, para as variáveis tempo e frequência de passos, verificou-se diferença entre
os sexos (p=0,001), sendo que os meninos realizaram a prova em menor tempo e maior frequência de passos que
as meninas.
Objective: evaluate the kinematics of race during 50 meters of 28 students from elementary school. Method:
for the kinematic evaluation were recordings of the sagital plane were accomplished during all the 50 meters. The total time of the races was measured and the in each five meters, the steps’ length, and were calculated the steps’ frequency and speed. Results and final considerations: the outcomes demonstrated that there were not significant differences in the steps’ quantity (p=0,417) and in the steps’ length (p=0,868) between the genders during the entire competition. However, for the steps’ time variability and frequency, the results showed difference between the genders (p=0,001), considering that the boys accomplished the race in less time and with more steps’ frequency
than the girls.
