Sažetak
The work evaluates the method and procedure for removing errors from data in the function of movement and anatomic points of the body in sports biomechanics, as well as calculation of their deratives. The selected method provides the transformation of the original data on the basis of determination of the frequency range of signals. In calculation of harmonics and signal phazes, the method of least squares was employed. The utility and behaviour of this method was compared with the analogously obtained data (Pezzack et al. 1977), and evaluated on the data concerning kinesiologic activity in sports gymnastics. The results show good consistency with the analogous data and their shift derivates. Therefore, it can be recommended as u suitable procedure for error removal and determination of higher derivates for the shift function in sport biomechanics.
