The study involving 8 men shows how drinking alcohol for 3 hours affected muscle protein synthesis.
The study tested the effects of alcohol on the body with different types of meals: whey protein after exercise, protein plus alcohol, and carbohydrates plus alcohol.
The use of alcohol, even along with protein foods, suppresses the anabolic response in skeletal muscles and therefore can impair recovery after exercise.
Want quality muscle mass? Alcohol must be forgotten.
