Efeitos de duas dietas isoenergéticas na composição corporal de praticantes de treinamento funcional.

Abstract

The demand for functional training has increased significantly in recent years, where practitioners combine resistance and aerobic training sessions, both for weight loss and tone and muscle mass gain. These practitioners can have their performance and results maximized through proper nutritional strategies. In this context, this study aimed to evaluate the effects of two types of isoenergetic diets on the body composition of functional training practitioners. For data collection, structured and adapted questionnaires were applied by some authors, and from the information obtained were designed two dietary protocols, as well as anthropometric evaluation before and after the application of these protocols, and the evaluation of nitrogen balance after the dietary intervention. The sample consisted of 7 functional training practitioners of both sexes and divided into two groups D1 and D2, who received two types of diet. The diet of group D1 consisted of 45% lipids, 30% carbohydrates and 25% proteins, while D2 consisted of 25% lipids, 60% carbohydrates and 15% proteins. A high-fat diet was offered on the premise that when carbohydrate percentages are low, this type of diet could increase the use of fatty acids as a fuel, as functional training is predominantly aerobic exercise and fat oxidation occurs in the diet. same situation. The mean ages of groups D1 and D2 were 39.33 ± 10.21 and 36.50 ± 8.7 years, respectively. The height presented was 1.67 ± 0.12 meters for group D1 and 1.58 ± 0.13 meters for group D2. Before the beginning of the dietary intervention the groups did not show significant differences between them for any of the analyzed parameters, demonstrating homogeneity. After 4 weeks of intervention, it was found that there were no statistical differences when analyzes between groups on anthropometric parameters, however, there was an improvement in the mean of these intragroups, and a decrease in body fat in groups D1 and D2. of -1.70 kg of fat (-1.67%) and -0.95 kg of fat (-1.25%), respectively, decrease in BMI and increase in lean mass. As for nitrogen balance, group D1 presented positive mean and D2 presented negative mean, so it can be seen that the fact that BN is positive is not only related to normal protein consumption, this is evident with the fact that Group D2 BN is negative even though consuming protein within the recommended values. Thus, it was observed that the use of the hyperlipid diet did not bring significant improvements in body composition compared to the conventional diet, but both protocols have brought benefits to practitioners such as fat loss, lean mass gain and well-being. From the above, adequate and individual nutritional monitoring of these practitioners is extremely important for them, and the nutritionist becomes indispensable in facing the challenges related to exercise and its changes on metabolism.
