Comparação do alongamento estático, balístico e contrair-relaxar nos músculos isquiotibiais

This study aimed to compare the effect of three stretching techniques (ballistic, static and contract-relax) on instant gain muscle flexibility on the hamstring muscle. We evaluated 23 subjects of both gender [means (SD) age 21.17 (1.4) years]. All volunteers performed static, ballistic and contract-relax stretching. Each technique was performed in a single session with an interval of seven days between sessions. To assess the immediate effects of the different techniques were performed two tests of flexibility, Sit and Reach Test and the Popliteal Angle Test. In comparison with the baseline there were significant increase in muscle flexibility in the Popliteal Angle Test after application ballistic (6.26%) and contract-relax technique (6.5%) respectively (p<0.05). When comparing the three techniques regarding the change score significant difference was found in the the Popliteal Angle Test for ballistic and contract-relax stretching, but Sit and Reach Test showed no significance difference. These data suggest that the ballistic and contract-relax were better than the technique of static stretching and both are equally effective. The ballistic contract-relax stretching techniques improved gain of muscle flexibility on the hamstring muscle.

Desempenho da tilápia-do-Nilo arraçoada com dietas contendo farinha de sangue bovino atomizado ou convencional

The study evaluated the performance and carcass composition index of Nile tilapia (Oreochromis niloticus) fed with diets containing increasing levels of spray-dried blood meal (SDBM) and vat-dried blood meal (VDBM) and formulated based on digestible amino acids. Two hundred and fifty-two fingerlings were distributed in a completely randomized design, in a (2 x 4) + 1 factorial model, two types of blood meal with four levels of each blood meal in the diet, and a control diet (without blood meal), with four replications. The treatments consisted of soybean meal-based control diet, with 34% digestible protein (DP) and 3,200 kcal of digestible energy kg-1 (DE), plus four diets formulated with SDBM and four diets with VDBM, containing 5, 10, 15 and 20% of each meal in feed, maintaining identical DP, DE, phosphorus, calcium, lysine, methionine, threonine and tryptophan levels as those of the control diet. The results show that it is possible to use up to 15% VDBM in diets of Nile tilapia (O. niloticus) between 5 to 150 g of body weight.

Biofertilizante bovino, cobertura morta e revestimento lateral dos sulcos na produção de pimentão

The adoption of management practices that reduce water losses is essential to conserve moisture and improve soil temperature, especially in arid and semiarid environments of the Brazilian Northeast, characterized by high evapotranspiration and the adoption of irrigation with saline water, which harms growth and yield of commercial crops. Given these factories, an experiment was conducted in Nova Floresta, Paraiba, from August 2010 to February 2011 in Oxisoil, in order to evaluate the production of bell pepper and soil moisture in grooves with side trim, and application of biofertilizer and mulch cattle. The experimental design was randomized blocks with four replications using a factorial 2 x 2 x 2 for the ground beef with and without biofertilizer, with and without residues of sisal fiber (Agave sisalana), with and without the side facing the grooves, to reduce lateral water losses by infiltration of water with polyethylene plastic film. From the results, the lining of the lateral grooves provided higher values of soil moisture, number of fruits, fruit mass, plant production and productivity, bell pepper plants. It was also found that the combination of biofertilizer and mulch the ground beef remained wetter in the first 15 cm depth.

Análise de investimento em confinamento bovino no centro-oeste brasileiro: um estudo de caso.

This study analyzed the economic viability of an investment in feedlot cattle on a farm in the midsize state of Goias. The research identified that different thematic studies whose interests have focused mainly on cost analysis and profitability punctual. Differently, this study used the approaches of the Discounted Cash Flow (DCF) and the Real Options Theory (ROT). The first used the projected cash flow for 10 years and a discount rate determined by CAPM at 8% p.a. for containment of heads 400. The second was modeled by the binomial model of Cox, Ross and Rubinstein (1979) incorporating the option of waiting. This methodology has not been employed in Brazilian cattle industry. The search results pointed to the economic viability of the project when considered possible scenarios for the different price ranges of the ox that state bushel. In addition, the TOR proved to be a more robust tool for investment analysis, by incorporating the flexibility of farmers to wait for the right time to make the confinement.
