Purpose: Patellofemoral Pain Syndrome (PFPS) is one of the common problems in active people specially, women. One of the consequences of this impairment is its effects on postural control which include static postural stability to dynamic activities. The aim of this study is to investigate effect of selected exercises on postural control in elite female Taekwondo players. Methodology: We chose 30 elite female taekwondo from female taekwondo players of Khorasan-razavi province with an average of 18 to 27 years old and 18 to 25 of BMI, voluntary. These 30 people divided to two experimental (1) and control (2) groups. Their balance and BMI measured by force plate and body composition system respectively. Data collection was 15 seconds in single leg position and closed eyes in which the knee was full extend. This procedure had repeated 3 times for non-dominant legs and the subjects were resting for 1 minute between each try. Inter-class and intra-class comparison calculated using independent T-test & paired samples T-test, respectively (P>0/05). Results: The results showed that there is a significant difference between pre-test and post-test in both of AP and ML components of first group, but there is no significant difference only in ML component of second group, in intra-class comparison. Also, in inter-class comparison the results showed that there is no significant difference between both of AP and ML components of two groups. Conclusion: Balance control during sport activity has an important role in injury prevention. The studies have shown that balance malfunction during sport activity has a considerable relationship with enhancement of ankle and knee injury. Finally, it could be express that selected preventive exercises during warm-up can probably avoid chronic injuries of knee joint especially patellofemoral pain syndrome with reduction of equilibrium fluctuations.
