Theoretically, errors introduced by the numerical integration process of a time series of data increase with time and noise-to-signal ratio; for this reason, the influence of number of repetitions and angular velocities on the estimated ROM was assessed using an analysis of variance for repeated measurements (within = repetitions, between = angular velocities).
