Evaluación de diversas fuentes de proteína (suplementos) sobre el incremento de la masa muscular de mujeres que realizan ejercicio anaeróbico de resistencia.

Abstract

This project was done to evaluate four different supplements based on various protein sources: 1) beef based, 2) vegan, 3) whey, 4) BCAA, and 5) a placebo cocoa powder-based control group. This study included 25 young female students currently enrolled in the Bachelor of Nutrition program of the Universidad de Monterrey, they were invited to participate in an eight-week research program and divided into five groups, each of the participants got a personalized meal plan with their assigned supplement or placebo in addition to a strength training plan. It was intended to observe the influence of the combination of resistance exercise and the intake of the selected supplementation on muscle growth and its related parameters. This was measured by an InBody 230® machine that works by the bioelectric impedance technology allowing to measure all the participants before and after the treatment. There were not statistical differences analyzed in the variables of weight, skeletal muscle mass, body fat mass, body mass index and protein to produce muscle, after eight weeks for supplements based on beef, vegan, whey and control group (cocoa); however, in the BCAA supplementation, the evaluation of the BMI showed a statistically significant decrease (p =
