ABSTRACT
Abstract "Creation, validation, and reliability of a shooting simulator instrument for reaction time evaluation." The aim of this study was to develop, validate, and verify the reliability of a shooting simulator instrument for reaction time evaluation. 90 Santa Maria Air Base military personnel participated on the study. Software was developed for use with an electronic gun where participants performed two shooting task tests: simple reaction time and choice reaction time. The results of concurrent validity were satisfactory, no significant differences were found between the two instruments and good agreement was observed. The reliability results were significant in both tests. The instrument can be used for research purposes, or for the purposes of military training as a simple, low-cost tool involving speed, accuracy, and decision-making shooting tasks.

Introdução: A prática do Jump em academias de ginástica vem sendo muito procurada pelo público feminino. Objetivo: Verificar os efeitos da prática de Jumpno equilíbrio e no tempo de reação de mulheres. Métodos: Fizeram parte do estudo 12 mulheres com média de idade 22,9 ± 3,31 anos. As participantes foram submetidas a 16 sessões de Jump, com duração de 60 minutos, cada. As sessões de prática apresentaram exercícios variados, contendo movimentos de giros, mudança de direção e passos com apoio unipodal e bipodal, coreografados. Resultados: Foram encontradas diferenças estatisticamente significativas para o tempo de reação simples (t= 6,36; p= 0,000). Esses dados indicam que a prática sistemática de Jump, é benéfica para a diminuição do tempo de reação simples de mulheres. Conclusão: Apesar da não verificação de diferenças estatísticas, o TRE e o equilíbrio mostraram ser capacidades importantes para uma vida mais ativa fisicamente.
Introduction: The practice of Jump in gyms is being sought by the female audience. Objective: The aim of this study was to investigate the effects of Jump exercise on the balance and reaction time of women. Methods: Twelve women with a mean age of 22.9 ± 3.31 years participated in the study. They had sixteen-jump exercise sessions with a duration of 60 min. Movements used in all sessions varied changed in direction and steps with a single leg, and bipedal support was applied. Results: Statistically significant differences were observed only in the simple reaction time (t = 6.36, p = 0.000), indicating that Jump exercise can improve simple reaction time. As for the balance and choice reaction time, even though there was an improvement from pre to post tests, the results were not statistically significant. Conclusion: Although there were no statistical differences, choice reaction time and the balance proved to be important capabilities for a more physically active life.

O objetivo deste estudo foi verificar a correlação entre equilíbrio, a marcha e o cognitivo de idosas. Foram avaliadas 20 idosas, com média de 70,70 ± 9,14 anos. Os instrumentos utilizados foram o Teste de Tinetti e o Mini-Exame do Estado Mental. Houve correlação significativa leve, somente entre a marcha e o MEEM (r=0,478, p<0,03), constatando que a marcha esta diretamente associada a concentração e coordenação, influenciada pelo cognitivo.
The aim of this study was to verify the correlation between balance, gait and cognitive elderly. 20 participants were evaluated with a mean of 70.70 ± 9.14 years. The instruments used were the Mini-Mental State Examination Test and Tinetti. There was a slight significant correlation only between the march and the MMSE (r=0.478, p<0.03), noting that the march is directly associated with the concentration and coordination, influenced by cognitive.
