Abstract: The purpose of this study was to determine whether a motor learning
effect exists during concentric isokinetic testing of the ankle invertor and
evertor muscles of the dominant and non-dominant leg. Thirty-three subjects
aged 22 to 57 years without any experience in isokinetic testing, were randomly
assigned to one out of three test velocity groups (30, 60 or
120°/s). Each velocity group consisted of 11
subjects. Invertors and evertors of the dominant and non-dominant leg were
tested. All subjects performed five sets of two maximal concentric
inversion-eversion movements on a calibrated CYBEX 6000 dynamometer. For the invertors of the dominant leg at 30 and
120°/s. the mean PKTQ%B the first set. For the
evertors of the dominant leg and the invertors and evertors of the non-dominant
leg no statistically significant difference was found. To exclude possible bias of learning effects in concentric
isokinetic testing of inversion-eversion muscles, we advise a practice session
of two sets of two maximal inversion-eversion movements.
