IntroductionThe quality of the protein availability is related to the amount of essential amino acid (EAA) that food contains. Energy and protein intake have a potent regulator to increase the fat‐free mass (FFM) synthesis, body composition measure should be considerate to the exercise performance. Athletes protein intake should be 1.5–2 g protein/kg/d.ObjectiveTo determinate the effect of EAA on body composition status in college athletesMethodologyInformation of the dietary intake was obtained by 24‐hour recall. This information was compared with the requirements for sports competitors. Nutrient intake values amounts were calculated using US Department of Agriculture database. Air Displacement Plethysmography was used to determinate FM and FFM percentages. Statistical analysis included a paired t test, to determinate the differences between the intake amount and the suggested; and linear regression analysis to determinate the effect of the EAA in the FFM.ResultsThirty athletes (18 males and 12 females) were evaluated. The mean amount of energy, fat, protein, and carbohydrates were 2493.1 kcal/d (SD=1278.83), 76.7 gr/d (SD=46.66), 115.43 gr/d (SD=62.95) and 301.07 gr/d (SD=160.37), respectively; and the 20% of deficient protein intake was showed. The amount of iron, 27.9 mg/d (SD=23.5). The protein and energy intake were lower than the requirement for sports competitors (p=0.0166 and p<0.0001). FFM was entered into the linear regression model as a continuous variable, the EAA were not significant (p=0.4961)ConclusionThis nutritional dietary analysis indicate a high protein deficit, 20%, that included the EAA, the synthesis of those EAA makes available a free pool to replace the protein degradation when the amount FFM is adequate. Therefore the nutritional intake recommendation has to be monitored by sports specialist using validated instruments. Despite of the result, the FFM has been not affected. Further research must be done in order to link the decrease inmuno‐malnutrition diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
