Danyshchuk A. Correction of foot arch disorders of young athletes specializing in taekwon-Do.

The dissertation presents an available information analysis on the state of foot arch disorder problem in young athletes at the present stage; data on preventive and corrective measures to restore the foot arch functional state of young athletes are presented; the role of myofascial kinematic chains in maintaining the physiological state of foot arch is considered; the characteristic of a complex of physical taekwon-Do I.T.F. exercises as bases of foot arch disorders correction of young athletes 7–8 year-old is given. The validity of scientific research methods, the adequacy of their choice regarding the object, subject, purpose and objectives of the work, the feasibility of the proposed methods were given, the study organization and the contingent was described. In order to solve the tasks set in the work, generally accepted scientific methods were used, which contained theoretical and empirical levels: research theoretical level (analysis and synthesis, generalization, induction and deduction, modeling); research empirical level (survey; pedagogical observation; instrumental research methods (plantography using the "DIERS FAMUS" (Germany) computer device, electroneuromyography using the electroneuromyographic complex "Neuro-EMG-Micro" (Russia), photometry, myotonometry using a myotonometer "SZIRMAI"); pedagogical testing of motor skills in general and technical elements of taekwon-do in particular; ascertaining and formative stages of the pedagogical experiment); methods of mathematical statistics. The ascertaining experiment results determined the need to find innovative approaches aimed at correcting disorders of foot arch of young athletes specializing in taekwon-Do I.T.F. The ascertaining experiment data allowed to evaluate the indicators of foot arch morphofunctional features of young athletes, foot linear-angular indicators and skeletal muscles biomechanical properties of individual “foot-shin” myofascial kinematic chains, responsible for supporting foot arch apparatus, also to find out the nature of motor units recruitment of anterior and posterior “foot-shin” myofascial kinematic chains while performing various sports taekwon-Do I.T.F. exercises, the level of physical fitness of 7–11 year-old young athletes both with foot arch disorders and without it.
