Programa de intervenção motora para escolares com indicativo de transtorno do desenvolvimento da coordenação - TDC

This study aimed to verify the effects of a motor intervention program for students with signs of DCD. Six 10 year-old students, both male and female, who were registered at a municipal school in the interior of the state of Santa Catarina participated in the study. Motor capacity was measured using the Movement Assessment Battery for Children (MABC-2), one of the most commonly used instruments for assessing childrens movement difficulties. The test encompasses the age groups of 3 to 16 years; for each age group, eight tasks are grouped into three skill categories: manual skill, throw and catch, balance. The interventions were based on the Developmental Physical Education approach in school environments. The sessions were done individually with 20 motor intervention sessions for each student, in a total of 120 sessions, frequency of two weekly classes with 45 minutes duration. The Wilcoxon test with the statistical package SPSS 13.0 for Windows was used for data interpretation. The results showed statistically significant differences after motor intervention (p <0,05). Regarding the results of motor skill performance, it was found that balance skills presented better improvement results after intervention, revealing that a motor intervention proposal was effective with children with signs of DCD. This study revealed the importance of promoting students with motor disabilities participation in intervention programs in order to monitor their motor development progress, so as to improve movement difficulties both in sports and in daily activities.

Análise do tempo de reação e do estado cognitivo em idosas praticantes de atividades físicas

The objective of this study was to investigate the correlation between reaction time and cognitive state of elderly women that are engaged in physical activities. We evaluated 77 elderly women (68.6 ± 3.9 years) that were participating in a structured program of physical activity. The Simple Reaction Time and Choice Reaction Time tests were evaluated by software tool and to the cognitive estimation; we used the Mini-Mental State Examination. The results were analyzed with the SPSS package, version 16.0, with a significance level of p <0.05 and before the non-normality of the data, Spearman correlation was chosen. The results observed in the tests represented a satisfactory score on the Mini-Mental State Examination, while for the reaction time the results were unsatisfactory. The correlation between the simple reaction time and cognitive state were considered significant and weak, it was hoped that with good results in cognitive state and by participating in physical activity, the women could show a shorter reaction time. Based on the information observed and considering the evidence that physical exercise helps in the efficiency of information processing by the central nervous system, it suggests, besides the practice of regular physical activity, motor and cognitive interventions that stimulate the plasticity of nervous system central should be promoted, with the purpose of contributing to the improved functionality of the elderly population.
