Abstract

Taxonomic analysis of motor abilities was carried out on 540 males aged between 19 and 27, who were evaluated of 110 tests of primary motor abilities. The algorithm for determination of polar taxonomic dimensions produced 16 latent variables sufficient to explain the common variance of all analyzed variables.
the first taxonomic dimension behaved as general factor of motor abilities defined, above all, by the systems for movement trajectories regulation, sinergic regulation and force regulation.
The second taxonomic dimension differentiated between the subjects with above-average abilities to carry put fast and complex movements and the subjects with above-average abilities to produce sub-maximum force in carrying out relatively simple movements.
The third taxonomic dimensions behaved similarly to the general flexibility factor, and the fourth as a sub-factor of flexibility of movement carried out in frontal plane and whose outcome is independent of fever length.
The fifth dimension differentiated between the subjects with above-average absolute arm force and the subjects with above-average relative endurance of arm muscles in isotonic and isometric work regime.
The sixth dimension, of a very narrow range, was probably the consequence of a differentiating effect of the absolute static endurance and the system for synergic regulation, where as the seventh behaved as a general factor of balance, largely determined by kinestetic sensitivity and efficiency of the system for movement trajactories regulation.
The eight dimension differentiated between the entities with above-average speed of simple movements of upper extremities and entities with above-average force of trunk flexors.
The ninth dimension was most likely and artifact of a test of great complexity, but the tenth differentiated between the entities with above-average ability for modulation of energy regulation and the entities with above.average tonus regulation.
The eleventh taxonomic dimension was more than once similar to the earlier isolated factor of leg coordination, while the twelfth differentiated between the above-average ability for synergic and tonus regulation as opposed to above-average ability for endurance of length efforts during isometric work regime.
The thirteenth taxonomic dimension differentiated a good synergic and tonus regulation during performance of leg movements, including as well the efficiency of the system for timing of movements, as opposed to the good energy regulation of leg movements regardless of the regime of work.
On the fourteenth taxonomic dimension were differentiated the entities who, beside strong legs, had an above average ability for performance of fast, strong and flexible leg movements.
The fifteenth taxonomic dimension was probably an artifact of relatively consistent motor systems which had and effect on the results of two motor tests, while the last one, the sixteenth, differentiated between the entities with somewhat above-average abilities for performance of rythmic structures as opposed to the entities of somewhat above-average other motor abilities.
The taxonomic approach to the analysis of motor abilities had produced results which wasy differ from results obtained through component or factor analysis.
The general factor of motor abilities was obtained through taxonomic analysis as well and is probably virtually identical with the general motor factor in the space of higher order.
Most other taxonomic dimensions, particularly these of a wider range, differentiate between entities with above-average efficiency of the system for movement trajectories regulation, synergic regulation and tous regulation, as opposed to the entities with above-average efficiency of the system for regulation of intensity and duration of energy output.
Different modulations of these regulatory systems often produce recognizable types of entities, and therefore it appears that taxonomic approach to analysis of motor abilities is of approximately identical scientific and practical significance generally attributed to the classic factor model in determination of latent dimensions.
