Is Alcohol Healthy? A Glass of Wine A Can of Beer By Elena Voropay If you train with weights, you probably care about your body getting stronger. How bad is your night out for the growing muscles? Depends on the amount of alcohol consumed.
Alcohol use inhibits muscular protein synthesis, which is essential for muscle growth and development. Alcohol adversely influences the anabolic properties of two principal growth promoting hormones, Insulin and Growth Hormone. Furthermore, most of the anabolic effects initiated by Growth Hormone are mediated by Insulin-like Growth Factor-1 (IGF-1). Muscle protein synthesis after exercise will not occur without them. What's more, alcohol causes insulin-resistance as well as hinders the release of Growth Hormone from the brain. Chronic alcohol consumption reduces our IGF-1 levels. These combined effects will slow down your muscle development despite your hard training sessions. |
