INFLUÊNCIA DA MANIPULAÇÃO DAS VARIÁVEIS DO TREINAMENTO DE FORÇA SOBRE PARÂMETROS DA COMPOSIÇÃO CORPORAL
Abstract
The problem with excess body fat grows every year and sedentary lifestyle is a major reason for the installation of this epidemic. The inclusion of strength training (ST) in people lives has proved a promising intervention in improving body composition. However, the better exercise method that promote changes in lean and fat compartments are not well elucidated. Therefore, this study examined the influence of different methods of ST in improving body composition in sedentary. Material and Methods: Seven male adult subjects, healthy, aged 18 to 30 years old, non-physically active, participated in a program of ST, four days a week for a period of 12 weeks. Participants were separated into two groups: H: Hypertrophy and R: Resistance Force, which received normocaloric diet through a food record. Anthropometric measurements and 1-RM tests were performed at the beginning and end of the study. Results: Both hypertrophy training and resistance strength significantly increased (p <0.05) muscle mass and strength gain over the period of twelve weeks. Since fat mass did not change due to the high consumption of carbohydrates, as was seen in the food record. Conclusion: We conclude that the practice of ST in 12 weeks is sufficient to alter body composition significantly, especially in lean body mass and strength. However, the ST without a controlled diet did not result in the loss of fat mass.
