the effect of eight weeks of selected exercises on the proprioceptive and electrical activity of selected leg muscles of elite male taekwondo practitioners in the prevention of PFPS injury

The aim of this study was to investigate the effect of eight weeks of selected exercises on the proprioceptive and electrical activity of selected leg muscles of elite male taekwondo practitioners in the prevention of PFPS injury. Thirty elite taekwondo practitioners divided into two groups of 17 experimental and 13 control. The experimental group, finished elected warm-up exercises within 8 weeks, 3 sessions per week, and 25-30 minutes per session and after that, special taekwondo exercises. But the control group, finished special taekwondo exercises for 90 minutes, only. evaluation of electrical activity of vastus medialis and vastus lateralis muscles ratio during Apdoliochigi we used electromyogragpy system and proprioceptive measured by center of pressure fluctuation components . For statistical analysis software SPSS and statistical methods for repeated measures and dependent test was used. The results showed that there was a significant difference between the effect of selected exercises on the proprioceptive and electrical activity of the knee muscles of male taekwondo players (P= 0/00), also a significant decrease in the post-test compared to the pre-test, although this difference was not significant in the control group. Selected exercises can possibly have positive effects on reducing the risk factors for patellar pain syndrome. These exercises can increase proprioceptive and improve electrical activity in elite taekwondo, balance the muscles of the knee area, and ultimately reduce the pressure on the patellofemoral joint and prevent patellar pain syndrome.
