This study analyzed the crank angular velocity across the pedaling cycle. The purpose was to compare values obtained from kinematic analysis to data gained through reed- switch sensors, which consider the cycle to have a constant angular velocity. Four well-trained cyclists were evaluated. The kinematic analysis was performed by using the Peak Motus System. The values of crank angular velocity at the four cycle quadrants were tested for differences. The results showed that velocity was not constant, because significant differences were observed among the cycle quadrants. The findings suggested that it is necessary to use more than one reed-switch sensors across the cycle, so that velocity variations may be detected. Furthermore, crank angular velocity can be used as a prime tool to analyse the subject’s pedaling technique.
