Objective: Proper activity of core muscles is essential for the stability of lumbar spine because of the unstable structure of the lumbar spine. Also stabilization of the core and pelvis is necessary for all movements of the extremities. In order to investigate how the central nervous system deals with this situation, the timing component of the muscles of core were evaluated during landing. Materials & Methods: to examine this task in healthy persons, 15 male subjects with no history of low back pain were studied. Surface electromyography electrodes were used to record the activity of selected core muscles. Results: Findings of this study indicated that core muscles activity occurs just prior feet touch the ground. Conclusion: Results suggest that the central nervous system deal with stabilization of the spine by contraction of the core muscle in anticipation of perturbation produced when feet touch the ground.
