DEPENDENCE OF PAIRED LIMBS MOTOR SYMMETRY-ASYMMETRY SIGNS ON MOTOR-COORDINATING ABILITIES OF SPORTSMEN, DOING PRACTICAL COMBAT SPORTS
Technical actions performance by sportsmen, engaged in applied martial arts under the conditions of competitive activities is associated with the of motor symmetry-asymmetry expressiveness of paired limbs in three – dimensional space relative to the body’s conditional planes location – sagittal, frontal and horizontal ones. Thus performance of technical actions by extremities is classified in the movement directions – to the right, to the left, either side and, forward-back. The phenomenon of motor symmetry-asymmetry is due to individual parameters of coordination abilities’ manifestation. The authors consider the correlation of motor symmetry-asymmetry of technical actions performance indicators of the upper and lower extremities with motor and coordination abilities parameters. The article presents the definitions of concepts related to the subject of the study: motor symmetry-asymmetry and motor coordination abilities’ integral indicator. The reliable correlation dependences of motor-coordination ability integral parameter with the preference to perform technical actions in accordance with the expressiveness of motor symmetry-asymmetry of paired limbs are revealed. The integral coordination ability parameter showed up a reliable connection with the following competitive activity indicators: the preference to strike and throw with both lower limbs, the preference to strike with the left lower limb, the change of the stand from the right to the left and vice versa, the consistency of «hand-foot» motor skills and the level of sportsmanship. These dependencies should be considered a fundamental trend, allowing pedagogical impact direction determining for the implementation of technical actions at various level of locomotor symmetry-asymmetry expressiveness of athletes’ paired limbs.
