Abstract

This study aimed to analyze the knee joint angles during the starting and the possible correlations with the final time of BMX cycling race in an official competition of the sport. Twenty (20) male athletes participated of this study, of “Elite” and “Junior Men” categories with a mean age of 20.3 ± 3.0 years old, which regularly participate of state, national and international competitions, all having more than five years of experience in BMX cycling competitive practice. The knee joint angle was measured three times during the beginning: in the static position, in the first noticeable movement and at the start time, in other words, to overcome the starting gate. Moreover, the correlation between the start angle and the total time of the Time Trial was made. It was found a significant difference between the angle of the first movement with respect to the angles of the static position and the start angle. There was no significant correlation between the start angle and the total time of the Time Trial. The study concludes that the total race time has no correlation with the athletes’ start angle, perhaps because, even as a short-term effort, on average 35 seconds, the curves and obstacles in the path are situations that make a difference for the best athletes in obtaining the best results.
