Canonical Relations between Speed Movement of Bilateral Parts of the Body

Since sensorimotor reactions of bilateral (parallel, transversal, diagonal) body parts represent the source, of a part of joint variability. This research study was conducted to affirm the relations of within these fields. In this research the velocity of bilateral (parallel, transversal, diagonal) body parts has been used as a dependent variable. The research was initiated by using lateralization functions, as well as interhemispheric interactions, and transmission speed of afferent and efferent impulses. The basic goal of the research is directed to affirm the relation of velocity between bilateral (parallel, transversal, diagonal) body parts. Considering that the morphological-functional structure establishes the dependency of the velocity of body parts or the whole body, a research was developed with the aim of verifying a part of the entire variable separated by the velocity of the bilateral (parallel, transversal, diagonal) body parts. The research was carried out on a sample of 20 subjects, of male gender, from 20 to 22 years of age. An analysis was carried out in the space of velocity of bilateral (parallel, transversal, diagonal) body parts. The evaluation of the velocity realized in bilateral structures was obtained through an especially constructed instrumentarium (Kinesiometer, M. Dodig, 1987) and calculating the pace obtained from basic kinetic elements (resistance, amplitude, time). Obtained results have been processed by application of canonical correlational analysis (Cooley and Lohnes, 1971). Based on maximum cohesion between the pair of linear functions of the group variables (parallel, transversal and diagonal body parts), two canonical characteristic roots have been isolated in every bilateral area have been extracted. Obtained pairs of canonical characteristic roots outline and define the bilateral (parallel, transversal, diagonal) velocity determinant of body parts. We are talking about a sequential regulation which consists of alternate activation and deactivation of certain groups of muscles, and which is important for fast execution of alternative motion where the velocity of the transversal and parallel body parts is prevalent. The basic reason of the obtained functional dependency between the velocity of bilateral body parts lies within the structure for regulation of excitation and partly the excitation intensity (activation of motor units) of various levels, synergic regulation and tonus regulation which are also determined according to bilateral structures.
