O efeito de atividades eqüestres no padrão motor do andar de crianças

Abstract

The human gait requests the interaction and the ripening of countless physiologic systems to give sequence to the necessary events to reach your efficiency. Inside of that perspective, recent studies have been demonstrating that the movement generated by the gait of the horse it has been providing countless benefits in the balance and, for consequent, in the children's gait when submitted the that activity. Those benefits happen because the step of the horse sends incentives to who it is mounted that resemble each other to the incentives originating from of the human gait. Before that, the objective of this study was to verify the effect of equestrian activities on the pattern motor of the children's gait. The study group was composed by 8 children with medium age 4,5 years old. All presented characteristics of the elementary apprenticeship of development of the gait, classified by a check list through the head office of analysis of movement of Gallahue & Ozmun (2005). The participants were distributed in two groups, control (G1) and experimental (G2). the cinematic verification of the gait was accomplished through the system of analysis of the movement Peak Motus™, using the reception of measures of time and space calculated by information supplied by events during a cycle of the gait. The filmings were accomplished in the plan sagital and frontal of way bidimensional with the rate of acquisition of the images of 60 Hz. The medium speed of the gait was controlled, being accomplished by the children in 4 km/h. After the first acquisition of data (pré-test), G2 participated in 12 sessions of equestrian activities, with duration of 30 minutes, accomplished twice a week. During the experiment they were controlled other activities to intervene in the results in both groups. Then of that experiment period new testagem was accomplished (powder-test). As statistical treatment, the Test of Shapiro-Wilk was applied to verify the normality of the data. The results proved a distribution non normal, having been applied the Test of Wilcoxon then to verify if there were differences among the right and left hemicorpos. The results didn't present significant differences among the hemicorpos, being used the averages of the same ones then for the analysis. For the verification of differences between the pré and the powder-test the test of Wilcoxon was used and for the differences among groups the test of Kruskal-Wallis. The trust level used in this study it was of 95%. The angular variables demonstrated significant alterations for both groups, however they were more expressive qualitativamente in G2. In the variables space-storms, there were only significant alterations in the length of the last and length of the step for G2. In the variable removal of the feet significant alterations were observed in just some subjects. It is ended that the proportionate equestrian activities were capable to unchain alterations in the pattern of the gait in children in elementary apprenticeship of development, and among the angular variables the results were more expressive in the articulation of the ankle and enter the space-storms, in the length of the step and of the last.
