Introduction: Balance and proprioception have been introduced as two of the most important internal factors related to the occurrence of injuries in the lower limbs. The purpose of this research is to investigate the changes in static and dynamic balance and proprioceptive accuracy of knee and ankle joints of young taekwondo athletes before and after applying the fatigue protocol.
Methodology: The current research is semi-experimental. The subjects of the research were 20 teenage male taekwondo players from the statistical population. Static and dynamic balance variables were measured respectively by Stork's static balance test and Y dynamic balance test, as well as the proprioception of the ankle and knee joints at 10 degrees of ankle dorsiflexion and 30 degrees of knee flexion, by the photographic method. Then the functional fatigue protocol was applied. After finishing the fatigue protocol, all the variables that were measured before applying the fatigue protocol were evaluated again. In order to examine the intra-group changes of the research variables in the pre- and post-test stages, the paired t-test was used.
Results: The results of the paired t-test showed that after applying the fatigue protocol, there is a significant difference between the average of all the investigated variables in the post-test stage compared to the pre-test.
Conclusion: The results of the present research showed that fatigue can reduce the static and dynamic balance as well as the proprioceptive accuracy of teenage taekwondo athletes. Therefore, it is recommended to all coaches and athletes of this sport, in order to delay the appearance of fatigue and the possibility of injury, to perform specialized training exercises in the field of taekwondo and according to the age of teenagers.
