Objectives:
To determine the physiological adaptations that might occur with a 4-week unilateral multiaxial training program in lower leg kinesthesia, peak torque, and postural control.
Study Design:
True experimental pretest-posttest control-group design.
Setting:
Research laboratory.
Subjects:
26 healthy, active subjects (14 men, 12 women).
Interventions:
Subjects were assigned to an experimental or control group. The experimental group performed multiaxial coordination training 3 days/wk for 4 weeks.
Main Outcome Measures:
Both groups were tested 3 times, pretest and 2 and 4 weeks after training was initiated. Outcome measures included conscious appreciation of ankle kinesthesia, eversion and dorsiflexion isokinetic peak torque, and static and functional postural control.
Results:
Results revealed a significant Group × Test interaction only for inversion kinesthesia.
Conclusions:
Four weeks of multiaxial coordination training did not significantly improve any of the dependent variables in healthy individuals. Further research should consider the effects of such a program on injured subjects.
