ABSTRACT
The aim of this study was to verify the effects of 22 weeks of training on functional markers and match performance through the use of earned points in competition. Twenty male soccer players were submitted to the same group of tests in four moments of the periodization: before the preparatory stage (T0); after the preparatory stage (T1); after the competitive stage I (T2); after the competitive stage II (T3). The functional markers were measured using the vertical and horizontal jump, T-40; Shuttle Run Test and RAST. The match performance was obtained by earned points in competition. An increase were found for all the variables analyzed for functional markers when T0 was compared with T3. In relation to the match performance, the team obtained 83.33% success in competitive stages. It is possible to conclude that training plan was efficient to improve technical-tactical skills and physical fitness of the studied athletes

The aim of the study was to verify the hydration status and the kidney function in marathoners during the training season and after a marathon race. Nine male runners were investigated during 12 weeks of training. Urine was collected in four moments; in the beginning (C1) and during (C2) the training program, before (C3) and after (C4) the competition. Urine pH was measured using reagent tapes, urine density with a refractometer, protein excretion by Bradford assay and erythrocytes and leucocytes by microscopy. Changes were observed when C-4 was compared to the other collection times for all variables investigated. It is possible to conclude that physical exertion induced important changes in the hydration status and glomerular membrane selectivity to macromolecules, modifying the kidney function of the marathoners in C4.
O objetivo do estudo foi verificar o estado de hidratação e a função renal de maratonistas durante uma temporada preparatória e após a competição. Foram estudados nove maratonistas durante 12 semanas de treinamento. A urina foi coletada em quatro momentos: antes (C1) e durante (C2) o protocolo de treinamento, antes (C3) e após (C4) a competição. Foram mensurados o pH a partir de tiras de reagentes, a densidade por meio do refratômetro, a proteinúria pelo ensaio de Bradford, concentração de eritrócitos e de leucócitos por microscopia. Alterações foram encontradas quando comparado o C-4 com as coletas anteriores para todas as variáveis estudadas. Pode-se concluir que o exercício físico induziu a modificações importantes no estado de hidratação dos corredores e na função da membrana glomerular, modificando assim, a função renal dos maratonistas no momento pós prova.
El objetivo del estudio fue determinar el estado de hidratación y la función renal en los corredores de maratón durante una temporada de preparación y después de la competición. Se estudiaron nueve corredores durante 12 semanas de entrenamiento. La orina se recogió en cuatro momentos: antes y durante el protocolo de entrenamiento, antes y después de la competición. PH de tiras reactivas, de densidad a través del refractómetro, proteinuria por Bradford ensayo, concentración de eritrocitos y leucocitos fueron medidos por microscopía. No se encontraron cambios al comparar el C-4 con las colecciones anteriores para todas las variables. Se puede concluir que el ejercicio induce cambios significativos en el estado de hidratación de los corredores y la función de la membrana glomerular, modificando de este modo la función renal del tiempo de maratón después de la carrera.

Rothia aeria is an uncommon pathogen mainly associated with endocarditis in case reports. In previous reports, endocarditis by R. aeria was complicated by central nervous system embolization. In the case we report herein, endocarditis by R. aeria was diagnosed after acute self-limited diarrhea. In addition to the common translocation of R. aeria from the oral cavity, we hypothesize the possibility of intestinal translocation. Matrix-assisted laser desorption ionization-time of flight mass spectrometry and genetic sequencing are important tools that can contribute to early and more accurate etiologic diagnosis of severe infections caused by Gram-positive rods.
