To the practitioners of resistance exercise, a better performance is associated with nutritional habits and the help of nutritional supplements. Whatever, this use has been made improperly and without foundation, advised by persons not trained, leading to misuse. To analyze the profile of practitioners in the knowledge of and access to supplements, as well as knowledge about the sport and the need to use additional food resources. A questionnaire will be used to youths aged 15 to 21 consumers of nutritional supplements on the sports, the substance used, why the substance used, who appointed her, which substances have been used, satisfaction with that product, and socioeconomic characteristics of the individual. The data will be correlated by Pearson's correlation coefficient. It is expected that the abuse of supplements is associated with ease by socioeconomic status and experience in the sport for the little progress with the adoption of a routine training exercise in the circumstances only. The major difference compared to the goal of practice, was the motivation for the improvement of physical fitness (Guaruja 21% and Bauru 9.6%), with the intention of increasing muscle mass response occurring closer (Guaruja 22% and Bauru 19.2%) among respondents, and reported more emphasis on the Interior Health (17.3%). The use of supplements is somewhat similar to trends involving body aesthetics and fitness for participation in sports, in the Coast (hypertrophy: 33% body fat reduction, improved endurance and improved performance in sports: 20%), and beauty, fitness and health, the Interior (hypertrophy: 41% increase in strength: 22%, and quality of life: 15%). Interest in the use of supplements is mostly aimed at the improvement of overload training (Guaruja 67% and Bauru 56%) but the sources of information on the use of supplements have become more secure among the respondents of the Interior (gym teacher: 20%, Conferences and Symposia: 12%, and the...

Growing in orange on Terra Mulata has been submitted nutrient limitation requiring correction in agricultural areas. The application of biochar associated with another source of nutrients can be a viable alternative to increase the efficiency of fertilizers and reduce losses in the areas. The objective of this study was to evaluate the effect of biochar, poultry litter and NPK in the nutritional status of orange trees grown in an Oxisol with anthropogenic A horizon (Terra Mulata). The study was conducted in a rural property landfall in Manacapuru (AM) in a randomized block design with eight treatments using biochar, poultry litter and NPK (4-14-8) applied in isolation and associates. To review two samples were taken at different periods of sheets to determine the nutritional status. Fertilizers applied did not increase the efficiency in the availability of contents of N, P, Fe and Zn, being the latter below the range of suitable content. As for the K, compost chicken manure and their combinations increased their availability, and the highest levels of Mg were found in the control treatment.

The proper mineral fertilization of guava orchards under intensive management, is a major factor in productivity and monitoring the nutritional status of the plants contributes to the efficiency of this agronomic practice. The aim of this study was to investigate different doses of nitrogen and potassium in the nutritional status of guava 'Paluma'. The experiment was conducted at Vista Alegre do Alto, Sao Paulo, in a 7 year old irrigated orchard, managed with fruiting pruning during four consecutive growing seasons. The soil is a dystrophic Ultisol. The experimental design was randomized blocks, in factorial, with four nitrogen doses (0, 0.5, 1 and 2 kg of N plant(-1)) and four of potassium (0, 0.55, 1.1 and 2.2 kg of K2O plant(-1)), with three replications. Nitrogen fertilization promoted increased levels of leaf N and Mn and the decrease in the levels of P and B; effects observed from the second to the fourth production cycle. Nitrogen fertilization increased the Ca and Mg levels, respectively, in the second and third cycle. Except for the first production cycle, K and Mn foliar concentrations increased with increasing potassium fertilization, whereas the levels of Mg, in the second and the fourth cycle, decreased as a function of fertilization.
