The purpose of the present study was to determine the effects of normative feedback on stability and efficacy of some selected muscles at different task difficulty levels in novice individuals. Thirty participants (age Mean= 22.60, SD=1.89 years) were randomly assigned into three groups of positive, negative normative feedback and control.  The experimental groups participated in 160 acquisition trials (16 blocks of 10trials) for 4 consecutive days (40 per day). Post test was performed after last practice session. The result of ANOVA-repeated measure test indicated that positive normative feedback group outperformed the other groups in stability indices of overall stability (P=0.004), anterior-posterior (P=0.01) and medial-lateral (P=0.001). In addition, the result of Covariance test at electromyography indices of the Soleus and Peroneus brevis showed significant differences in the favor of positive normative feedback in post-test. The findings of the present study showed that normative feedback has functional motivation affect that directly influences physiological changes level of stability control.

KEY WORDS: Electromyography, knowledge of result, normative feedback, performance, stability control.
