Abstract

Chocolate milk has been suggested to be an effective post-exercise recovery beverage due to the ideal carbohydrate-to-protein ratio, while taurine supplementation may increase energy expenditure and favor carbohydrate metabolism. Therefore, research examining the combination of taurine with chocolate milk after exercise on insulin action in order to favor carbohydrates’ metabolism regulation, assist with muscle recovery, and prevent protein catabolism is warranted. The purpose of this study was to evaluate the effects of taurine and chocolate milk supplementation on body composition and nitrogen excretion in triathletes. A double-blind, crossover study was conducted with 12 male triathletes, age 25 to 35 years. Three grams of taurine and 400 ml of chocolate milk (TAUchoc) or a placebo (400 ml of chocolate milk; CHOC) was ingested post-exercise for eight weeks. A two week washout period was implemented between trials. Body composition was measured using the deuterium labeled-water method and 24-hour urinary nitrogen excretion was measured using the chemiluminescent method before and after eight weeks of training and supplementation with TAUchoc or CHOC. An ANOVA suggested TAUchoc during the eight weeks resulted in a significant, p= 0.029, reduction in urinary nitrogen excretion by 33 percent, while CHOC provided significant reductions in body weight, PRE: 77.4 ± 2.4 kg and POST: 76.5 ± 2.3 kg, p=0.034, and body fat percentage, PRE: 17.8 ± 1.2 percent and POST: 15.5 ± 1.5 percent, p=0.036. In conclusion, the addition of taurine to post-exercise chocolate milk consumption prevented protein catabolism, while chocolate milk alone resulted in a more favorable body composition.
