Concordância dentre dois testes de capacidade aeróbia máxima em jogadores de futsal: teste de Ellestad e o vai e vem de 20m

O futsal é uma modalidade intermitente cuja a participação do metabolismo aeróbio é importante na ressíntese de ATP e CP gastos anaerobiamente. A capacidade aeróbia máxima (VO2max) pode ser mensurada por testes de campo e testes laboratoriais. Dentre os vários testes laboratoriais existentes, se destaca o teste de Ellestad, devido à sua segurança e capacidade diagnóstica de patologias cardíacas. Dentre os testes de campo se destaca o teste de Vai e Vem de 20m (VV20m), devido à sua alta validade e reprodutibilidade em adultos, e devido à alta especificidade ao futsal e ao futebol, comprovado pela existênicia de correlações significativas do desempenho no VV20m com várias medidas de performance no futebol. Porém, não existem estudos sobre a validação ou concordância do teste de Ellestad em atletas de esportes coletivos. Portanto, o objetivo do presente estudo foi testar a concordância do teste de Ellestad e o VV20m na predição do VO2max em atletas de futsal. Quinze jogadores semi-profissionais (25,4 ± 5,51 anos, 70,37 ± 5,74kg, 1,75 ± 0,04m e 8,43 ± 3,02% de gordura) realizaram os testes de Ellestad e o VV20m em ordens aleatórias, separados por quatro dias. A concordância foi testada pela comparação entre as diferenças (Teste t-studet para dados independentes), correlação (coeficiente de Pearson) e concordância (dipersão de Bland e Altman). Não houve diferença significativa entre os valores de VO2max estimados pelos dois protocolos, mas a correlação foi significativa (p < 0,05; r = 0,479; EPE: 1,8 mlO2×kg -1 ×min -1 ) entre os métodos. A análise de Bland e Altman apresentou concordância entre os testes para um intervalo de ±95% em torno da média da diferença (1,3 mlO2×kg -1 ×min -1 ), porém a dispersão indica um enviesamento positivo e significativo (p < 0,01), sugerindo que a a diferença aumenta com o aumento da média do VO2max. Assim, para atletas de alto rendimento, o teste de Ellestad não apresenta a mesma adequação na determinação do VO2max, quando comparado ao VV20m.

Variáveis determinantes do desempenho em provas de curta duração em nadadores masters

Twenty-four masters swimmers participated in the study (42.0 ± 7.4 years, 1.74 ± 0.09 m, 74.8 ± 14.1 kg). Countermovement jump (CMJ) and 3 kg medicinal ball throwing (BM) were performed. At a 25 m swimming pool, each subject completed a maximal 50 m front crawl swim with in water start, 25 and 50 m performances (T25, T50) were recorded. Anaerobic critical velocity (AnCV) was determined by the slope of the distance-time relationship (Dd-t) in the two swimming distances. T25 and T50 (respectively 19.0 ± 2.7-sec and 38.8 ± 6.4-sec) were correlated with CMJ (27.2 ± 5.0 m) (respectively, r = -0.78 and -0.73, p < 0.01), and BM (4.3 ± 1.0 m) (r = -0.68 and - 0.58, p < 0.01). AnCV25,50 (1.31 ± 0.23 m.s-1 ) was correlated with T25 (r = -0.92, p < 0.01 ) and T50 (r = -0.98, p < 0.01). The strength parameters turn out to be important in aquatic performance in masters swimmers and AnCV may be relevant in the training of masters swimmers.

Produção do monóxido de titânio em estrelas variáveis

Mira are pulsating variable stars in advanced stages of evolution. Their atmospheres are sources of intense absorption bands attributed to molecular titanium monoxide (TiO). It has been suggested that the abundance of TiO reaches its maximum value near the minimum light. In this sense, the study of the processes of formation and destruction of TiO in circumstellar envelopes of Mira stars, not only allows us to understand the physical and chemical processes that occur in these environments, as it allows to verify the correlation between the abundance of TiO and its light curve. However, the main mechanisms of formation and destruction of TiO are poorly known and, consequently, the possible correlation between the abundance of this species and the light curve. In these sense, we studied the main processes of formation and destruction of titanium monoxide in molecular layers of Mira atmospheres and determined its temporal variation as function of the stellar radius. The TiO profile along the radius was expected for the different stellar phase, however its abundance is not enough to explain the light curve. The reasons behind it are discussed in details

Geoprocessamento de variáveis morfométricas para caracterização da microbacia do Córrego do Petiço

This study aims to perform the morphometric characterization of the watershed stream Petiço, Botucatu-SP, through techniques of GIS by GIS IDRISI Selva and Charter planialtimetric Botucatu (SF-22-ZB-VI-3) , edited by IBGE (1969), scale 1: 50000 for ranking the drainage network and the morphometric analysis. The variables analyzed were the dimensions, the relief pattern, pattern of the drainage network and the shape variables. The results show that related to how the watershed has an oblong shape with environmental interpretation with low tendency to flooding and erosion. The sinuosity index of 1.22 shows that the channels of the micro tend to be somewhat sinuous, which allows to infer that is permeable soil with good water infiltration. Based on the results of the morphometric variables was found that the watershed is in good condition of conservation, however, presents certain risks of susceptibility to erosion, and environmental degradation in some points, being fundamental to the maintenance of vegetation cover, in view of the roughness coefficient (Rn). Thus, the evaluation of morphometric characteristics in the study watershed constitutes an important tool in conjunction with the use of GIS and Geographic Information Systems makes possible the planning and management of natural resources aimed at their conservation.

Variáveis morfológicas da cana-de-açúcar em função do regime hídrico durante o desenvolvimento inicial

Water deficit is one of the factors which most limit agriculture yield and growth. Although sugar cane has moderate tolerance to drought, it presents high yield losses under the influence of this abiotic factor. Based on this fact, selection of genotypes tolerant to water stress may represent an alternative for decreasing the amount of water used for irrigation, while keeping or increasing yield. This study was performed in order to evaluate the performance of four sugarcane cultivars during initial development under water stress conditions, by means of morphological variables to select more tolerant genotypes to drought. The experiment was carried out in a greenhouse at the Department of Rural Engineering, College of Agricultural Sciences - UNESP/Botucatu – SP, from November 26th 2010 to April 5th 2011. A total of four sugar cane cultivars were evaluated (RB855453, RB92579, RB965902 and RB965917) under two treatments as follows: control (100% field capacity) and water stress (50% field capacity). Evaluations were performed at 0, 28 and 63 days after treatment application. The following morphological variables were analyzed: plant height, leaf area, leaf length, leaf width, number of green leaves, shoot and root dry matter. The RB855453 and RB92579 cultivars produced more shoot and root dry matter under water stress treatment, while the RB965902 and RB965917 cultivars had lower shoot and root dry matter production under the same conditions. Therefore, the RB855453 and RB 92579 cultivars can be considered tolerant while the RB965902 and RB965917 cultivars can be considered susceptible.

Incorporação de incertezas associadas à predição de modelos hidrológicos aos instrumentos de gestão em recursos hídricos

Water management has in the watershed plans an important tool to plan the territory and adjust the activities develop over it to the natural resources availability. The incorporation of uncertainty analysis associated with hydrological modelling predictions is a manner to simulate scenarios and work with chances and probabilities that certain events happens inside these plans. Using stochastic methods is possible to consider uncertainty from estimations and even model it. Stochastic methods developed considerably during the last 30 years, but its applications to real-world problems have been limited, and did not turn into routine in hydrology. This paper brings an overview from eminent hydrologists about this subject and discuss the Brazilian and Paulista situation in the scope of groundwater monitoring.
