Efeitos de oito semanas de treinamento de natação no limiar anaeróbio determinado na piscina e no ergômetro de braço

O objetivo deste estudo foi analisar os efeitos do treinamento de natação na intensidade do limiar anaeróbio (LAn), determinado na piscina e no ergômetro de braço, verificando se este pode ser utilizado para avaliar os efeitos do treinamento em nadadores. Participaram do estudo sete nadadores de ambos os sexos, com nível de performance regional, que foram submetidos aos seguintes testes, antes e após oito semanas de treinamento: 1) dois tiros de 400m, um a 85% e outro a 95% do máximo, com coleta de 25mil de sangue do lóbulo da orelha no 1º, 3º e 5º minuto após cada tiro, para posterior análise do lactato sanguíneo (YSI 1500); 2) teste contínuo progressivo realizado no ergômetro de braço (UBE 2462 Cybex), com carga inicial de 33,3W e incrementos de 16,6W a cada três minutos até a exaustão voluntária, com coleta de sangue ao final de cada estágio. Um grupo controle de indivíduos não ativos (n = 9), que se manteve sedentário, realizou somente o procedimento 2 no mesmo intervalo de tempo. O LAn na natação (NLAn) e no ergômetro de braço (BLAn) foi encontrado através de interpolação linear, considerando uma concentração fixa de lactato de 4mM e 3,5mM, respectivamente. Os resultados demonstram diferença significante para o grupo treinado, entre o pré (130,4 ± 20,4W) e o pós-teste (137,7 ± 17,9W) para o BLAn. Porém, não foi encontrada diferença significante para o NLAn (1,09 ± 0,1m.s-1 e 1,13 ± 0,1m.s-1, p = 0,06). No grupo controle não foi encontrada diferença para o BLAn entre o pré (93,2 ± 11,5W) e o pós-teste (87,7 ± 7,2W). Pode-se concluir através desses dados que a determinação do LAn no ergômetro de braço é útil para detectar adaptações na capacidade aeróbia de nadadores com nível de performance regional.

Measurements of gunshot residues by sector field inductively coupled plasma mass spectrometry - Further studies with pistols

The most popular handgun in Brazil is the single round-barrel caliber 0.38 revolver. In recent years, however, owing to the modernization of police arms and their availability on the legal and illicit markets, pistols have become increasingly popular and currently represent about 20% of police seizures. In a previous paper we presented a novel collection method for gunshot residues (GSR) using a sampling procedure based on ethylenediamine-tetraacetic acid (EDTA) solution as a complexing agent on moistened swabs with subsequent detection using sector field-high resolution-inductively coupled plasma-mass spectrometry (SF-HR-ICP-MS). In the present paper, we discuss the capability of this methodology to identify antimony (Sb), barium (Ba) and lead (Pb) on the hands of volunteers after shot tests with 9 mm and 0.40 in. caliber pistols. Two types of munitions were tested: 9 mm Taurus and clean range. The use of a technique with high sensitivity, such as SF-HR-ICP-MS, permits the identification of low concentrations (less than 1 mu g/L) of metals in firearm residue and constitutes a powerful tool in forensic science. We also discuss the importance of the sampling procedure, including collection from a different body part than the gun hand of the suspect. Comparison of the analytical data obtained allows clear discrimination between samples from the hands of shooters and non-shooters. (C) 2007 Elsevier B.V.. All rights reserved.

Situação vacinal infantil e características individuais e familiares do interior de São Paulo

The aim of this study was to describe and analyze individual and family characteristics of children and those of health services, as well as their relationship with the immunization status for different kinds of vaccines and doses. Three sources of information were used: records from the Municipal Health Information System, immunization charts, and interviews using closed-ended questions. The families interviewed still had one or two growing children; caretakers were usually young unemployed mothers with easy access to health services. Around 30% of them were not instructed on the vaccine being given, its reactions or when to return for the next shot. The greatest levels of tardiness occurred with the vaccines against measles (6.3%) and Haemophilus influenzae B (4.2%). It was possible to observe that tardiness or absence of vaccinations seem to have a stronger relationship with service characteristics than with population characteristics.

Methodology for DSC calibration in high heating rates

Despite the large use of differential scanning calorimetry (DSC) technique in advanced polymer materials characterization, the new methodology called DSC in high heating rates was developed. The heating rate during conventional DSC experiments varying from 10 to 20°C.min-1, sample mass from 10 to 15mg and standard aluminum sample pan weighting, approximately, 27mg. In order to contribute to a better comprehension of DSC behavior in different heating rates, this work correlates as high heating rate influences to the thermal events in DSC experiments. Samples of metallic standard (In, Pb, Sn and Zn) with masses varying from 0.570mg to 20.9mg were analyzed in multiples sample heating rate from 4 to 324°C. min-1. In order to make properly all those experiments, a precise and careful temperature and enthalpy calibrations were performed and deeply discussed. Thus, this work shows a DSC methodology able to generate good and reliable results on experiments under any researcher choice heating rates to characterize the advanced materials used, for example, for aerospace industry. Also it helps the DSC users to find in their available instruments, already installed, a better and more accurate DSC test results, improving in just one shot the analysis sensitivity and resolution. Polypropylene melting and enthalpy thermal events are also studied using both the conventional DSC method and high heating rate method.

Análise comparativa dos sistemas de jogo e das ações técnicas realizadas pela seleção brasileira de futebol

Since its origin, soccer has been conquering followers all over the world. As a consequence of this cultural phenomenon, countless works are being done aiming to analyze the game systems and the fundamentals carried out by a team. The purpose of this paper is to analyze the Brazilian Soccer Team’s game systems and actions with ball possession in the 1958, 1962 and 2002 World Cup finals. Specifically, the paper analyzed the actions that occur during the match, such as control, dribble, pass, shot, foul and tackling. In order to achieve that, the Skout software (Barros et al., 2006) was utilized and, through it, all fundamentals carried out by the Brazilian team were identified and codified in a virtual field. The data from each match was transported into the Matlab® software, in which the zone of major action of each player was analyzed, represented by the main axis. The outcome showed that the game systems put into practice by the Brazilian team in the 1958 and 1962 World Cup finals didn’t present significant changes, nevertheless, regarding the 2002 final, there was a great difference. The Brazilian team got similar percentages in the technical actions carried out in the three World Cup finals analyzed, however, in absolute numbers, the passes, the shots and the dribbles decreased while the fouls increased.
