Efeito da prática regular de atividade física no desempenho motor em idosos

the slowing down in information processing, particularly at the level of sensory information, decision and movement programming in elderly is a consequence of aging. the present study investigated simple reaction time and coincidence-anticipation in 44 physical active and in 33 non-physical active male and female elderly individuals, with chronological age between 60- to 89-years-old (m = 73.7; sd = 7.4 years). the multi-choice reaction time was used to measure simple reaction time (srt) and the bassin anticipation timer was used to evaluate coincidence-anticipation (ca). these abilities play a major role in the functionality and well being of the elderly. each participant performed with the preferred hand a total of six trials in the srt task and twenty trials in the ca task. the results showed that the physical active group outperformed the non-physical active group in both tasks and only in this group males were better than females. a faster information process in males could underlie this outcome. since the two abilities evaluated in this study constitute an expression of the functional integrity of the central nervous system, the results suggest that systematic practice of physical activity can delay and be an important protector against the effects of aging in the perceptual-motor processes involved in this type of tasks.
