ABSTRACT
ABSTRACT Introduction: Taekwondo is a complex reactive sport that requires training in various tactics. Due to its significant impact and antagonism, athletes must master the tactics in the shortest time. Objective: To compare the impact of password and simulation training methods on athletes' reaction times. Methods: Taekwondo athletes› reactions and striking abilities were studied. The difference between the two training methods on taekwondo athletes' reaction and striking ability was analyzed by comparing the data before and after the athletes' training. Results: The mean reaction times of down kick, sidekick, and cross kick after training in the password and simulated training groups were compared, with P values of P=0.020<0.05, P=0.046<0.05, and P=0.028<0.05, respectively, showing statistical difference. In regard to the mean strike time of down kick, sidekick, and cross kick, a comparison of the password training group and the simulated training group resulted in P=0.950>0.05, P=0.417>0.05, P=0.552>0.05, respectively, with no significant statistical difference. Conclusions: The password training method is significantly better than the simulation training method for improving the reaction time. The training methods have no significant effect on strike strength. Level of evidence II; Therapeutic studies - investigation of treatment results.
RESUMO Introdução: O taekwondo é um esporte complexo e reativo, que exige treinamento em várias táticas. Graças a seu impacto significativo e antagonismo, os atletas precisam dominar tais táticas no menor tempo possível. Objetivo: Comparar o impacto dos métodos treinamento password e treinamento por simulação no tempo de reação dos atletas. Métodos: A velocidade da reação e dos golpes de atletas do taekwondo foram estudadas. A diferença nos resultados entre os dois métodos de treinamento foi analisada, comparando-se os dados antes e depois do treinamento dos atletas. Resultados: Comparou-se os tempos de reação dos grupos password e simulação para o chute baixo, o chute lateral e o chute cruzado após os respectivos treinamentos, obtendo-se os valores P=0,020<0,05, P=0,046<0,05, e P=0,028<0,05, respectivamente, demostrando assim diferença estatística. Quanto ao tempo médio dos golpes chute baixo, chute lateral e chute cruzado, a comparação entre os grupos password e simulação resultou em P=0,950>0,05, P=0,417>0,05, e P=0,552>0,05, respectivamente, indicando ausência de diferença significativa. Conclusões: O método de treinamento password é significativamente melhor que o método de treino por simulação na melhoria do tempo de reação. Não houve diferença significativa no efeito dos métodos de treinamento sobre a força dos golpes. Nível de evidência II; Estudos terapêuticos - investigação do resultado de tratamentos.
RESUMEN Introducción: El taekwondo es un deporte complejo y de reacción, que exige entrenamiento en varias tácticas. Gracias a su impacto significativo y antagonismo, los atletas necesitan dominar tales tácticas en el menor tiempo posible. Objetivo: Comparar el impacto de los métodos entrenamiento password y entrenamiento por simulación en el tiempo de reacción de los atletas. Métodos: La velocidad de la reacción y de los golpes de atletas del taekwondo fueron estudiadas. La diferencia en los resultados entre los dos métodos de entrenamiento fue analizada, comparándose los datos antes y después del entrenamiento de los atletas. Resultados: Se compararon los tiempos de reacción de los grupos password y simulación para la patada baja, la patada lateral y la patada cruzada después de los respectivos entrenamientos, obteniéndose los valores P=0,020<0,05, P=0,046<0,05, y P=0,028<0,05, respectivamente, demostrando así diferencia estadística. En cuanto al tiempo promedio de los golpes patada baja, patada lateral y patada cruzada, la comparación entre los grupos password y simulación resultó en P=0,950>0,05, P=0,417>0,05 y P=0,552>0,05, respectivamente, indicando ausencia de diferencia significativa. Conclusiones: El método de entrenamiento password es significativamente mejor que el método de entrenamiento por simulación en la mejoría del tiempo de reacción. No hubo diferencia significativa en el efecto de los métodos de entrenamiento sobre la fuerza de los golpes. Nivel de evidencia II; Estudios terapéuticos - investigación del resultado de tratamientos.
ABSTRACT
Objective To study the impact of different general anesthesia on T-lymphocyte subsets in patients underwent laparoscopic colorectal resection. Methods 80 patients with laparoscopic colorectal cancer resection were selected from March 2008 to June 2012. According to the difference of general anesthesia, there were 28 patients (Group A). There were 27 patients (group C) who underwent general anesthesia. Patients of the three groups were examined for the level of T lymphocyte subsets during anesthesia. Results CD3+, CD4+ and CD8+ levels were significantly decreased in all the three groups after general anesthesia, CD4+/CD8+ and NK cells in group B were significantly decreased, and CD4+/CD8+ in group C was significantly decreased. The levels of T1 and T2 in group B were significantly lower than those in group A, and the levels of CD3+ and CD8+ in group C were significantly lower than those in group A, and the other indexes except T2 were significantly lower than those of group A, and group C T1 CD8+ was significantly lower than that in group B, NK cells were significantly higher than those in group B, and CD4+in T2 was significantly higher than that in group B. Conclusion Intravenous general anesthesia has the least effect on T lymphocyte subsets in patients undergoing laparoscopic colorectal cancer resection, and the effect on immune function is the slightest.
