Sponsor's own description

A strength training session promotes increased muscle sensitivity to protein synthesis, which lasts for 24 hours after its closure. Recent studies have shown that the subsequent intake to the training session of approximately 20g or 0.24g / kg of high-quality protein in the same meal induces a plateau in this synthesis. Thus, this study aims to compare the muscular strength between vegetarian and omnivorous athletes with adequate protein intake to reach this plateau. It will recruit 64 university sportsmen who have maintained vegetarian or omnivorous diet for at least 6 months, totalizing 32 individuals per group. After signing the Term of Consent, participants will be submitted to anthropometric and body composition assessment (via DEXA), neuromuscular tests \[(ie, muscle strength - 1RM, peak torque of knee extensors (JE), muscle thickness of JE and cohort analysis (ANCOVA) will be used in order to compare the results of the study, and to compare the results of the covariance analysis (ANCOVA). the levels of the neuromuscular parameters between the groups, considering the initial values of the force and the initial muscular thickness as covariables, the other parameters will be presented in the form of mean and standard deviation or median, the differences will be considered significant for values of p \<0, 05. Expected to find no differences in strength and muscle thickness between vegetarians and omnivores after adequate protein intake.
