Alcohol Before Exercise?

Hey Davey,

I like to have a few drinks before hitting the gym. It helps me relax after work, but is alcohol hindering my workout?

From,
Chris

The research is very clear: Yes. Alcohol and exercise don’t mix.

First, studies have found that drinking before working out hinders the circulation of glucose – which the body uses for energy. If you have less energy during your workout, you’re not going to be working at your full potential – and your results will suffer. It also results in a decrease in blood glucose levels after working out; glucose is important for muscle recovery.

Second, it’s dangerous. Even small amounts of alcohol can impair judgment and coordination. Add hundreds of pounds of weight plates into the mix and you have a recipe for disaster.

Third, though drinking doesn’t accelerate the negative effects of cortisol – it does prolong these effects, according to the Journal of Applied Physiology. The stress hormone cortisol has a catabolic effect on your muscles and thus can negatively affect your strength and size gains.

Fourth, alcohol hinders protein synthesis. By slowing the production of muscle proteins needed to grow you muscles, you also slow the gains you’re making at the gym.
Dehydration.

Fifth, you’re more likely to become dehydrated. Alcohol is a strong diuretic (i.e., it makes you pee…), and dehydration and electrolyte imbalances can result. This can negatively impact your performances, and – in extreme cases – even result in death.

Sixth, there are a whole slew of other, less-immediate but still negative impacts from alcohol consumption.

  1. Decreases in testosterone. While there is still some debate on the effects of naturally-occurring testosterone levels on muscle growth, we do know what binge drinking can lower testosterone levels.
  2. Increases in body fat. Alcohol has 7 calories per gram, and those drinks can really add up. These calories are considered empty calories – much like drinking a can of soda – because they don’t provide nutrients that the body can use.
  3. Health problems. Alcohol consumption can cause liver damage, heartburn, ulcer development and other health complications.  Longer term, chronic drinking may lead to impotency, liver failure, vitamin deficiencies, pancreatitis, and other conditions.

But it’s not all bad news. At least one study found that, despite all the complications resulting from alcohol, drinkers tend to live longer. Maybe it’s all those antioxidants in wine.

The bottom line: If you do want to consume alcohol, drink occasionally and always in moderation – but never before working out.

  1. Just keep alcohol for weekends only, works for me.

    Drinkers do tend to live longer. I recently saw an interview with a lady who turned 104 and one of her routine things to do is have a small glas (standard 3,5 cl) of jenever in the afternoon around tea-time. She had been doing that for the last 50 years or so and is convinced that it has helped her reach her age with a healthy mind.

      Due to my work schedule, I tend to work out after work, which I find to be a better way to unwind after work anyways. However I do like to drink. In fact, I really like to drink. So on my days off from the gym I enjoy a gin & tonic. On my gym days, I take my pre work out instead. My co-workers have started to perpetuate a rumor that I’m gonna start mixing my pre-work out with gin so I can do both on the same day…

    never drink before working out-bad for concentration-and all of above mentioned in this blog.

  3. It’s important to always take the safe and healthy route.

  4. J I was going to suggest Davey place his blog adsrdes on the window for the neighbour to see but thought that that would be overly breaking the illusion .If you’ve seen my previous posts I’ve alluded to similar outrageous goings on in Davey’s condo with regard to camera equipment and the drag makeover.All I can say is, life is never dull in the House Of Wavey , but I feel there’s a certain degree of anonymity that makes this all possible.

  5. Just wanted to set the record straight. There’s actually never been a controlled study showing that drinking makes you live longer. It’s a urban legend. Someone a long time ago happened to look at census data and noticed that people who drink regularly have a longer life span. But there’s a huge selection bias in this data. Example: (1) regular drinkers tend to be more affluent and have access to better healthcare, which might explain this result. Or (2) you only drink when you’re healthy, so people in the long life span category have already self selected themselves as healthy individuals.

  6. I read this paragraph completely on the topic of the difference of newest and preceding technologies, it’s awesome article.
