Brazilian Journal of Biomotricity , 2010,
Abstract: COLEDAM, D. H. C.; SANTOS, D.; DOS-SANTOS, J. W. Change on vertical jump after competitive period in professionals soccer players. Brazilian Journal of Biomotricity, v. 4, n. 2, p. 140-147, 2010. Soccer is a sport that demands different intensities of run, with decisive actions of a match being held in maximum intensity. Vertical jump test is widely used in soccer players due to the strong relationship with speed and agility. Futhermore, there are little information about change on vertical jump after the competitive season in soccer players. The aim of this study was to analyze change on vertical jump after the competitive season in professional soccer players. Took part in this study 21 male athletes (20.82 ± 3.16 years, 72.28 ± 8.74 kg and 179.91 ± 6.14 cm) subscribers to the 4th division of the Paulista championship of 2009. The competitive season had a duration of 20 weeks, with a total of 20 official matchs done. The test used was the counter-movement vertical jump (VJ), that was performed in the first (PRE) and last (POS) training session of the competitive period. After confirmation of data normality by Kolmogorov-Smirnov, the inferential analysis of the results of VJ between PRE and POS was performed using the paired t-test, considering the significance level of 5%. There was a significant increase (p<0,05) on VJ after the competitive period (PRE=54,19±4,46 and POS=57,94±5,23). According to the results of this study, it is possible to increase the performance of VJ in professional soccer players after the competitive period of 20 weeks duration.

Abstract: Os objetivos do presente estudo foram: 1) verificar a rela o dos saltos vertical, horizontal e sêxtuplo com a agilidade e velocidade de 5, 10 e 25 m; 2) verificar a capacidade desses saltos em predizer o desempenho da agilidade e velocidade de 5, 10 e 25 m em crian as. Vinte e oito meninos (9,47 ± 0,64 anos) e 30 meninas (9,69 ± 0,70 anos) foram avaliados. Os valores de correla o entre a agilidade, velocidade de 5, 10 e 25 m foram, respectivamente, r = 0,63, 0,51, 0,44 e 0,64 com o salto vertical, r = 0,68, 0,62, 0,28 e 0,62 com o salto sêxtuplo, e r = 0,60, 0,50, 0,26 e 0,57 com o salto horizontal. O salto vertical e o salto sêxtuplo foram capazes de predizer o desempenho da agilidade e da velocidade de 25 m (p < 0,05). Além disso, demonstraram capacidade de predizer a velocidade de 5 e 10 m, respectivamente (p < 0,05). Os testes de salto vertical e sêxtuplo podem ser utilizados para avalia o e controle do treinamento com crian as praticantes de atividades que demandam agilidade e velocidade, uma vez que ambos os saltos predisseram o desempenho da agilidade e velocidade, o que n o ocorreu com o salto horizontal. The aim of the present study were: 1) To verify the relationship of vertical, horizontal and sextuple jumps with agility and velocity of 5, 10 and 25 m; 2) To verify the capacity of these jumps to predict the agility and 5, 10 and 25 m velocity performance in children. Twenty eight boys (9.47 ± 0.64 years) and thirty girls (9.69 ± 0.70 years) were evaluated. The correlation values between agility and velocity on 5, 10 and 25 m velocity were, respectively, r = 0.63, 0.51, 0.44 and 0.64 with vertical jump, r = 0.68, 0.62, 0.28 and 0.62 with sextuple jump, and r = 0.60, 0.50, 0.26 and 0.57 with horizontal jump. The vertical and sextuple jumps were able to predict the agility and 25 m velocity performance (p < 0.05). Furthermore, they demonstrated capacity to predict 5 and 10 m velocity, respectively (p < 0.05). The vertical and sextuple jump tests may be used for assessment and control of training with children practicing activities that require agility and velocity, since both jumps predicted the agility and velocity performance, which did not occur with the horizontal jump.

Abstract: Although dynamic and stretching exercises have been widely investigated, there is little information about warm up performed by tag games. Thus, the purpose of the present study was to verify the acute effect of dynamic exercises compared to a tag game warm up on agility and vertical jump in children. 25 boys and 24 girls participated in this study and performed the agility and vertical jump tests after warm up based on dynamic exercises or as a tag game lasting 10 min each in two different days randomly. Dynamic exercises warm up consisted in a run lasting 2.5 min followed by 2 series of 8 dynamic exercises lasting 10 seconds each interspersed with 20s of light run to recovery. Tag game warm up was performed by a tag game with two variations lasting 5 min each. The first variation there was a single cather, which aimed to get the other participants by touching hands. In the second part of the game, the rules were the same except that the participant that was caught had to help the catcher forming a team of catchers. Warm up intensity was monitored by OMNI perceived exertion scale. ANOVA 2x2 for repeated measures (Warm up x Sex) demonstrated no significant differences between dynamic exercises and tag game for agility and vertical jump (P>0.05) for boys and girls. Perceived exertion was significantly higher in tag game compared to dynamic exercises on girls (P<0.05). Both warm up models showed similar acute effects on agility and vertical jump in children.

Abstract: Objetivo: Presentar un sistema para corregir quirúrgicamente la epífora ante obstrucciones del sistema lagrimal que se presentan de difícil resolución por alteraciones en fosa nasal, traumatismos o cirugía previa. Métodos: Se realiza una dacriocistorrinostomía (DCR) por vía externa, colocando una doble intubación concéntrica a nivel de saco lagrimal y fosa nasal introduciendo un elemento de interposición macizo de silicona en otro cilindro hueco, anclado en la abertura del saco. Se practicó la técnica en 27 casos durante los a os 2001 y 2002, en pacientes afectados por traumatismos faciales con fractura ósea que compromete el sistema lagrimal (diez casos), con cirugía nasal previa (cuatro casos), con DCR fallida previa en el mismo lado (seis casos), y con DCR previa fallida en ojo contralateral (siete casos). Resultados: Son valorados según la ausencia de lagrimeo, el vaciamiento del menisco lagrimal, y la permeabilidad objetivable del sistema lagrimal mediante paso forzado de líquido. Los Resultados globales indican una tasa de eficacia de la técnica de un 85%. El análisis por grupos refleja una eficacia del 90% en pacientes con traumatismo facial previo, del 75% en pacientes sometidos a cirugía nasal previa, del 83% en operados de DCR previa en el mismo ojo, y del 71% en operados de DCR con mal resultado en el ojo contralateral. Conclusiones: El método presentado nos parece una buena solución en los casos de obstrucciones bajas del sistema lagrimal de pacientes con patología previa, en los que sospechamos un fracaso al enfrentarnos a la cirugía convencional de repermeabilización.

Abstract: Caso clínico: Paciente con carcinoma recidivante de fosa nasal que invade pared orbitaria interna, sin afectar al contenido orbitario. Se emplea, para la reconstrucción, una malla doble de prolene anclada a periostio. Discusión: El prolene es un material adecuado para sustituir la pared orbitaria, proporcionando estabilidad a la órbita sin afectar a su contenido. Tras la cirugía la motilidad ocular es normal y la malla no tiene desplazamiento. ésta es una buena opción para reemplazar el hueso extirpado en los casos en que sea necesario realizar una reconstrucción de la pared orbitaria interna.

Abstract: psychological depression is an independent risk factor for coronary artery disease. c-reactive protein has been implicated as a mediator of the effect of psychological depression. several studies have found that individuals, especially men, who report higher levels of psychological depression also have higher levels of c-reactive protein. the current study was undertaken to replicate these results in a brazilian population, in which there is a much wider range of variation in both background characteristics (such as socioeconomic status) and coronary artery disease risk factors. a sample of 271 individuals was interviewed using the center for epidemiological studies depression scale. fasting blood samples were obtained and evaluated for c-reactive protein (assessed by a turbidimetric immunoassay using a dade behring kit) analysis in a subsample (n = 258) of individuals. the mean ± sd c-reactive protein for the entire sample was 0.43 ± 0.44, with 0.42 ± 0.48 for men and 0.43 ± 0.42 mg/l for women. data were analyzed using multiple regression analysis, controlling for age, sex, body mass index, socioeconomic status, tobacco use, and both total cholesterol and low-density lipoprotein cholesterol. higher reported depressive symptoms were correlated with higher c-reactive protein for men (partial r = 0.298, p = 0.004) and with lower c-reactive protein for women (partial r = -0.154, p = 0.059). the differences in the associations for men and women could be a result of differential effects of sex hormones on stress reactivity and immune response. on the other hand, this difference in the associations may be related to gender differences in the disclosure of emotion and the effect that self-disclosure has on physical health and immune response.
