Abstract
The purpose of this study was to evaluate the effects of vibration exposure on the neuromuscular responses to inertial-based trunk perturbations. Thirteen, male participants (mean = 22.5 yrs ± 3.2) were assigned to one of two experimental groups: 1) participants not exposed to vibration (control group - CG, n=6), and, 2) participants exposed to vibration (vibration group - VG, n=7) throughout the protocol. Participants experienced 40 perurbations, of which half were in known and unknown directions. Data from trunk sEMG, motion capture markers and seat accelerometers were anaylzed. Repeated measures ANOVA with Tukey's post hoc test were used to determine statistical significance (p<0.05). Participants in CG had a 14% faster muscle onset time than VG. Antagonistic muscle onset times were faster than agonists in both groups. Perturbations of known direction did not show any anticipation effects both in sEMG amplitude and in L4-5 joint angle.
