CV: coefficient of variation, assessed within trials and averaged across all trials; aRMS: averaged root-mean-square acceleration, given in multiples of 9.81 m/s2 (g); aMax: peak acceleration within each cycle, given in g; Ap2p: peak-to-peak amplitude, given in mm; Power of the 1st harmonic in % of the total signal power. Data are given as means (SD).
