The effect of internal and external attention focus on the postural sways and EMG's changes in the elite gymnasts

The Aim of Present study was to examine effects of Attentional focus on performance (postural sways) and EMG’s changes. Thus, 10 Athletes (19-26 Years old) with at least 10 years experience in Gymnastics, in a counterbalanced manner performed under tow conditions of internal (focus on legs) and external (focus on stabilimeter plate) focus. In each condition, 10 trails 20 seconds conducted. Postural sways using Biodex Stabiliometer device and EMG signals using ME6000 recorded and analyzed using paired t test. Results showed no effects on balance performance of skill athletes and reduced EMG activity under external focus. Research findings (reduced EMG) supports Constraint action hypothesis. Although attentional Focus have no effects on balance performance of skilled athlete but it can have profound effects on motor behavior and the underlying neurophysiologic including completing action with more efficiency in external focus and skilled athletes will used its advantages at least in movement quality.
