Background: Consumption of high quality protein and carbohydrates post resistance exercise has been shown to increase muscle mass while decreasing muscular damage. Eccentric only exercises have been shown to increase muscle hypertrophy and strength.;Methods: Twenty-three resistance-trained males age 18-30 enrolled in this study and were randomly assigned to either a 29 g whey protein isolate or 132.5 g whey and carbohydrate beverage following an 8-week eccentric only resistance weight lifting protocol. 19 participants tested one-rep maximum tests for the bench press and leg press along with anthropometric measurements prior to, halfway through, and following completion of the study.;Results: Split-plot repeated measures ANOVA revealed that both groups experienced significant increases in muscle strength, muscular hypertrophy, and lean body mass.;Conclusion: There was a statistically significant (p<0.05) increase in muscle strength, hypertrophy, and lean body mass following the eight-week eccentric resistance training study. However, the increases were due to the lifting protocol and not a specific supplement consumed.
