Changes in latent structure of motor dimensions under the influence of kinesiologic operators

The research was done on the sample of 216 male examinees of 15 years of age with the aim to investigate the changes of the inner structure and functional mechanisms responsible for variability and co-variability of manifested motor reactions under the influence of applied kinesiologic operators. A battery of 24 motor tests was applied to examine the motor dimensions of examinees in the initial and final states. Factorial structure of motor dimensions of the initial and final states (Little Jiffy, Mark IV Kaiser & Rice, 1974) was analysed. The existence, transformation and congruence (Tucker method) of the structures obtained under the influence of applied operators were determined. From the manifested variable sphere seven latent dimensions were extracted in both the initial and final states, and then interpreted as factors of: repetitive and explosive strength, coordination, speed, static strength, flexibility and balance. The specific definition of latent structures in the final state is expressed through inner determination and specificity prior to application of kinesiologic operators. This difference is expressed as quantitative change of structure in the dimensions of: speed, static strength, repetitive strength, explosive strength, flexibility and coordination. No considerable change occurred in the structure of balance. The congruency of latent structures in the initial state with structures obtained in the final state led to information about real latent structure and qualitative structural changes under the influence of applied kinesiologic operators. Changes in the latent structures of motor dimensions that occurred under the influence of kinesiologic operators are based on qualitative formation of structure, as well as on the structural unity of latent dimensions. This applies to the mechanisms for regulation of excitation intensity and excitation duration ; the mechanism for movement structuring ; and the mechanism for functional synergy and tonus regulation. Changes in regulation mechanisms had influence on the achievement of adequate results in the following manifested reactions: explosive, repetitive and static strength, speed, coordination and flexibility. On the other hand, there were no important changes in the balance structure.
