A fast reaction to visual stimuli is important for the success of any athlete. A fast reaction time enables a quick response in key situations. We have studied how age, sport engagement, moderate physical activity and lateralization affect the simple reaction time to visual stimuli in schoolchildren between the ages of 9 and 13. The reaction time to visual stimuli was statistically significantly shorter in older children compared to younger ones. The sport club basketball players who had been training and playing basketball for several years had a statistically significantly shorter reaction time to visual stimuli compared to schoolchildren of the same age from a rural environment who did not engage in sports. Moderate physical activity and lateralization did not significantly affect the reaction time values. The simple reaction time to visual stimuli was used in this study to evaluate the speed and explosive abilities of young basketball players. By training certain movements, we managed to improve their reaction time and thus influence the quality of their game. Integrating training of these skills into sport clubs and schools would affect the improvement of basketball performance and the prevention of injury.

Este estudo teve como objetivo rever criticamente a literatura científica publicada na última década (2003 a 2012) sobre o uso de testes de tempo de reação simples com estímulo visual relacionada à Educação Física, mais especificamente objetiva apresentar uma síntese da evidência empírica disponível sobre a eficácia do uso deste tipo de teste no esporte, exercício e atividade física, buscando na base de dados eletrônica Thomson Reuters Web of KnowledgeSM. A partir das combinações de palavras “simple reaction time e athlete”, “simple reaction time e sport”, “simple reaction time e exercise” e “simple reaction time e physical activity”, 36 artigos foram selecionados para o estudo. As categorias investigadas foram: periódico, número de participantes, sexo e idade, população investigada, software utilizado, tema e resultados. As publicações se concentraram nas revistas Medicine and science in sports and exercise e Psychology of sport and exercise, ambas com n=3. Predominaram pesquisas com o uso de testes de tempo de reação simples com estímulo visual (TRSimples) para avaliação do efeito do exercício físico sobre o desempenho no TRSimples (n=13) com uma média de 93 participantes (11 a 551 sujeitos). As populações de atletas investigadas foram variadas, com predominância do futebol e atletismo (ambas com n=5). A maioria dos estudos utilizou o software ANAM (Automated Neuropsychological Assessment Metrics) como instrumento de coleta de dados do TRSimples. Os artigos foram identificados e apresentados quanto ao seu tema de pesquisa: a) Uso do TRSimples para avaliação da concussão cerebral causado por traumatismo na cabeça (n=8); b) Efeito do exercício físico sobre o desempenho no TRSimples (n=13); c) Níveis de prática e comparações do TRSimples de atletas e não atletas (n=8) e d) Fatores que influenciam o TRSimples (n=7). Os resultados dos artigos apontaram associações positivas entre o uso de testes de TRSimples e a concussão cerebral originada pelo esporte além do efeito positivo do exercício físico sobre o desempenho cognitivo. O TRSimples contribuiu para análise dos níveis de prática de atletas de mesma modalidade, de modalidades distintas e de não atletas, além de ser um indicador sensível a diversos fatores que podem influenciar o desempenho cognitivo.

Reaction Task

For 20 subjects reaction times and force of response were measured on a simple reaction time task to visual stimuli while activation was manipulated by occasionally delivering a noninformative electrical shock. In blocks in which shocks were delivered, forces of response were larger than those in control blocks without shocks. The results are discussed in terms of Sanders' mode! of stress.

Response Stimulus

Aggrandized fluctuations in the series of reaction times (RTs) are a very sensitive marker of neurocognitive disorders present in neuropsychiatric populations, pathological ageing and in patients with acquired brain injury. Even though it was documented that processing inconsistency founds a background of higher-order cognitive functions disturbances, there is a vast heterogeneity regarding types of task used to compute RT-related variability, which impedes determining the relationship between elementary and more complex cognitive processes. Considering the above, our goal was to develop a relatively new assessment method based on a simple reaction time paradigm, conducive to eliciting a controlled range of intra-individual variability. It was hypothesized that performance variability might be induced by manipulation of response-stimulus interval’s length and regularity. In order to verify this hypothesis, a group of 107 healthy students was tested using a series of digitalized tasks and their results were analyzed using parametric and ex-Gaussian statistics of RTs distributional markers. In general, these analyses proved that intra-individual variability might be evoked by a given type of response-stimulus interval manipulation even when it is applied to the simple reaction time task. Collected outcomes were discussed with reference to neuroscientific concepts of attentional resources and functional neural networks.
