Análise dietética com ênfase em proteínas e do balanço nitrogenado de atletas amadores do jui jitsu brasileiro em Cuité-PB.

Abstract

Brazilian Jiu Jistu is a predominantly aerobic sport with system activations anaerobic. As it is composed of standing and ground fighting, it involves several body components and different strength exercises. With that, muscle power training should be highlighted, especially for executing the techniques that lead to the opponent's submission. For this, protein is an important item in the diet, and its consumption should be associated with the consumption of other macronutrients, carbohydrates mainly. Because to develop muscle mass, it is necessary to maintain a positive nitrogen balance. This study aimed to analyze the protein intake and nitrogen balance of Brazilian Jiu Jitsu athletes from Cuité-PB. For data collection, structured questionnaires were applied, food recalls of 24 hours and anthropometric assessment. 24-hour urine processing for determination of urea and nitrogen balance calculation was also performed. The sample consisted of 11 amateur athletes of Brazilian Jiu Jitsu, being I O male and 1 female, with mean age of 23.20 ± 5.70 years (standard deviation), weight of 79.89 ± 20.67 kg, height of 1.75 ± 0.09 meters and percentage of fat of 14.51 ± 6.02%, all males. They presented an average energy consumption of 2,887.00 ± 940.60 kcal/day and one consumption normal average protein 1.62 ± 0.60 g/kg/day, along with a low intake of carbohydrates 54.78 ± 5.67%, which were analyzed using Avanutri®. The nitrogen balance it was positive in all athletes. Protein consumption with a view to adequacy of the nitrogen balance must also take into account factors such as adequacy. energy sources, quality and timing of protein intake. the possible damages from excessive protein consumption for athletes in general are still not good settled down. Thus, the importance of adequate nutritional monitoring and individual for them. In this perspective, it is recommended that future studies are extremely important to elucidate and set standards with regard to mechanisms that contribute to increased athletic performance. Given this, the work shows us that an adequate protein intake does not necessarily lead the individual to positive nitrogen balance, there are other factors that should be taken into account, like the negative energy balance.
