Alcohol’s Side Effect On Training: The Bitter Truth About “Alcohol Effects” On “Muscle Growth”

Alcohol consumption is something that you should always try to stay away from that because alcohol has a huge side effect on our brain and body. But if you’re an alcohol consumer, then keep it in a low-dosage possible. Training or physical activities don’t mix with Alcohol consumption at all. 

It’s been a long stressful week, but finally, the weekend is here!

The first thing a lot of people want to do is get out, have a drink of their favorite alcoholic beverage, and relax.

But what about the muscle you’ve been trying so hard to build all week?

You’ve been training hard all week and your diet has been nailed. Now you’re wondering… what effects the alcohol you’re drinking may have on your muscle growth? So today I’m going to take a look at alcohol and muscle growth.

There are obvious health risks with drinking alcohol, but I’m only going to be covering the negative impact that it can have on your hard-earned muscle gains.

In this post, I’m going to break this down into just three major players in the building muscle process, and how alcohol affects each of them.

1. Protein Synthesis

Now for those that don’t know, protein synthesis is the process that takes place in your body where protein, in the form of food, is turned into muscle. Protein synthesis occurs when the muscles experience small micro-tears, brought on after sufficient resistance training. The small micro-tears are repaired through protein synthesis which leads to bigger, stronger muscle fibers.

Inhibited Muscle Protein Synthesis

Now, we know that Protein Synthesis is essential for muscle growth. Well, scientific research has discovered that drinking alcohol actually inhibits Protein Synthesis, so, in effect, alcohol stops your muscles from growing. One such study was reported in the “American Journal of Physiology, Endocrinology, and Metabolism” in 1999. The research concluded that alcohol has a blocking effect on protein synthesis which leads to a reduction in muscle mass.

In 2001, an article was published in the “International Journal of Sports Nutrition and Exercise Metabolism” found that meals consumed within a 24-48 hour window after resistance training had the greatest effect on muscle growth (also referred to as muscle hypertrophy).

With this information, we know that drinking alcohol on a training day is going to have a detrimental effect on muscle building. If you do want to have a drink, make sure that you never do it on a training day.

A more recent study by Australian exercise scientists found that post-exercise alcohol inhibits rates of muscle protein synthesis, reinforcing this body of data. You can see the results from the study on the graph below:

2. Testosterone

Most people know what testosterone is, but just in case you’re not aware of how important this stuff is when it comes to muscle growth, read this quote:

“Testosterone is a steroid hormone from the androgen group – androgens promote protein synthesis. Testosterone’s anabolic effects include growth of muscle mass and strength, increased bone density and strength.”

Alcohol’s Impact on Testosterone

Testosterone, the highly potent muscle-building hormone, the stuff steroids are made from, is crucial for maximum muscle growth. You want as much of this stuff as possible, but unfortunately, studies have shown alcohol lowers testosterone levels.

Research published by “Alcoholism: Clinical and Experimental” in 2004 found that a group of subjects who drank alcohol had significantly lowered testosterone levels compared to a group that had no alcohol.

Lowered testosterone means reduced protein synthesis. Alcohol not only reduces testosterone but also raises estrogen, which is the worst possible hormone combination for growing muscle.

3. Growth Hormone

This is another important player in the muscle-building process, as well as other functions in the human body.

Impact on Growth Hormone

Much like the hormone testosterone, Growth hormone helps with protein synthesis (muscle building) and just like testosterone, you want lots of this stuff. The maximum release of growth hormone in the human body occurs during sleep. Resting is when your muscles grow, so when you’re sleeping, your body releases growth hormone which is great for muscle growth. However, research has shown that the growth hormone release during sleep is suppressed by alcohol.

How To Drink and Keep Building Muscle

If you like a drink, the good news is that you don’t need to give up alcohol completely in order to build muscle

Now I’m no angel when it comes to drinking alcohol, I like to drink sometimes and have a good time with friends and family, but I don’t let it have a negative impact on my physic. Binge drinking every weekend is not going to help with your muscle gaining goals. However, going out once a month or once every couple of months is not going to get in the way of your muscle gains too much.

If you’re just starting out with building muscle and you’re serious about changing your body, then you should stay off drink completely from the first few months to maximize your muscle gains. By doing this, you’re giving yourself the best possible chance from success and placing your body in a state to produce maximum muscle.

A Few Tips When Drinking Alcohol

Try and keep yourself hydrated when you’re drinking alcohol. I don’t mean you have to stand in a bar with a bottle of water in one hand and a beer in the other, that’s probably going to earn you some funny looks. Just try and slip a few glasses of water in when you’re drinking, and drink a full glass at the end of the night, just before bed.

Before I go out for a good drink, I make sure I’m well-fed and hydrated. I’ll eat some slow-digesting protein like a steak to make sure my muscles are still being fed with protein to maintain muscle and a slow carb source such as sweet potatoes to maintain energy levels.

Obviously, timing when you’re drinking alcohol is a good idea too. Make sure that you don’t drink on the same day as you’re training, because of alcohol’s negative effects on protein synthesis, testosterone, and growth hormone. Training in the afternoon then heading out for a drinking session the same night is not a good idea as this is when your muscles are in most need of good nutrition and rest in order to grow.

Drink on your days off from the gym, but also avoid drinking when you’re training the next day… hangovers and the gym don’t mix!
