Effect of different dietary patterns on performance and body composition in individuals engaged in resistance Training
Abstract
The practice of resistance training (RT) has been proved effective in increasing strength, lean body mass and reducing body fat. However, the influence of different dietary patterns in performance and improvement in body composition is not well understood. Objective: To assess the impact of different dietary patterns on strength and body composition in trained individuals engaged in eight weeks of RT. Materials and Methods: Ten healthy, male and trained individuals (at least six months of training experience), between 18-24 years old, who were not using any type of food supplement, engaged in four days a week RT, for eight weeks. We applied a three-day food record and performed anthropometric measurements and the 1-RM at baseline (p0) and at the end of the study (p8). We compared the participants in order to analyze the relationship between diet and TR. Results: Four participants completed the study. Positive correlation between increasing lean muscle mass and strength gains in the 1-RM in bench press (r = 0.983). However, there was no relationship observed between different macronutrients distributions and body composition improvement. Conclusion: Other factors independent of diet and nutrient timing seem to influence muscle hypertrophy and improved body composition in individuals engaged in TR.
