The effects of alcohol on bodybuilding and sports

Alcohol is often part of sports culture, especially in team sports. However, recent research highlights its harmful effects on muscle recovery. A groundbreaking study reveals how alcohol consumption after exercise can compromise your gains, even with optimal protein intake.

How is alcohol metabolized in our body?

Alcohol is primarily broken down by the liver through a process involving several enzymes. This transformation has significant repercussions on your body’s overall functioning, notably on energy production and protein synthesis.

Biological reactions when drinking alcohol

Imagine your body as a well-oiled machine. When alcohol enters the scene, it’s like a grain of sand slipping into the gears. Your liver, like a diligent worker, immediately gets to work to eliminate it. This cleaning process mobilizes a large part of your body’s resources, much like the entire factory comes to a halt to fix this small issue.

The body puts everything into action to eliminate alcohol as a priority, thus focusing less on other processes.

The liver primarily uses two enzymes for cleanup. The first, alcohol dehydrogenase (ADH), transforms alcohol into a substance called acetaldehyde. But beware, it’s not over! Acetaldehyde is then converted into acetate by a second enzyme, aldehyde dehydrogenase (ALDH). It’s like alcohol goes through two stages of recycling before being completely eliminated. All this work for just one drink!

You might be wondering what impact all this has on your athlete’s body? Well, this process disrupts quite a few things! It produces an excess of a molecule called NADH, which disrupts the energy balance of your cells. Consequence? Your body struggles to produce sugar and use fats as fuel. (Not ideal when you want to perform, you’ll agree!) Moreover, to break down alcohol, your liver mobilizes an enzyme called cytochrome P450. The problem is that this enzyme is normally responsible for handling other substances. Result: it is no longer available to deal with certain medications or supplements you might be taking.

Why is alcohol bad for sports?

Alcohol is a real saboteur of your sports performance, negatively affecting almost every aspect of your physical condition. It decreases your endurance, slows your reflexes, and disrupts your coordination, potentially turning your athlete’s body into a much less efficient machine.

You’ve worked hard to reach your current level, haven’t you? You train hard, eat properly, sleep well, and take high-quality muscle supplements. Well, let us tell you that alcohol might be reducing all your efforts.

Let’s see together why this drink is so harmful to your sporting achievements.

🚫 The 3 major impacts of alcohol on your performance

Alcohol sabotages your performance on multiple levels. Discover how it concretely affects your athlete’s body.

• Negative effects on performance: Alcohol is like putting low-quality fuel in your sports car’s tank. Your overall performance takes a hit! Studies have shown that even moderate alcohol consumption can reduce performance by 10 to 15%. (Disruption of energy metabolism).
• Impact on hydration and endurance: Alcohol is a real hydration vampire. It increases urine production, which can dehydrate you quickly. Even slight dehydration can reduce your performance. Alcohol dilates your blood vessels, which can increase blood flow to your skin and reduce it to your working muscles.
• Consequences on reaction time and coordination: If you play a sport that requires precision or quick reflexes, alcohol is your worst enemy. Even in small quantities, it slows your reaction time and disrupts your hand-eye coordination. Alcohol also affects your balance and proprioception.

What are the effects of alcohol on your muscles?

Alcohol has a significant negative impact on your muscles, particularly on muscle protein synthesis and recovery. It can seriously hinder your progress in bodybuilding by slowing muscle growth and disrupting post-workout repair processes.

💪 The 3 mechanisms by which alcohol sabotages your muscles

• Impact on muscle protein synthesis: Alcohol consumption can reduce muscle protein synthesis by up to 37%! Alcohol interferes with the mTOR pathway, which plays a crucial role in muscle growth.
• Effects on muscle recovery: After exertion, your body needs to recover. But alcohol disrupts this process. It increases cortisol production (catabolic hormone) and dehydrates your body, slowing tissue repair.
• Consequences on muscle hypertrophy: By disrupting protein synthesis and slowing recovery, it limits your ability to build muscle mass.

How many drinks in bodybuilding and sports?

Scientific research shows there is no “safe” alcohol threshold for athletes looking to optimize muscle gains. Even moderate consumption can negatively affect protein synthesis and muscle recovery, with impacts increasing as consumption rises.

📊 What studies teach us

Scientific work reveals that alcohol interferes with muscle growth processes, even at relatively low doses.

📈 A dose-dependent relationship

The effects of alcohol on your muscles follow a dose-dependent relationship: the more you drink, the more negative effects accumulate. Binge drinking is particularly disastrous.

🎯 How to balance sports and social life without sabotaging your gains?

To limit the negative effects of alcohol on your sports performance, moderation and timing are essential.

• Strict limit: Maximum 1 drink on training days.
• Crucial timing: Avoid alcohol within 3-4 hours after your workout.
• Hydration: Alternate with water.
• Slowed absorption: Eat before and during.
• Strategic choice: Opt for low-alcohol beverages.
• Periods of abstinence: Especially before competitions.

Will quitting alcohol help you gain muscle?

Quitting alcohol can indeed boost your muscle mass gain and improve your performance. Not only do you optimize protein synthesis, but you also significantly enhance the quality of your sleep, a key factor in recovery and muscle growth.

💪 The muscular benefits of sobriety

• Top protein synthesis: Your muscles better receive growth signals.
• Restorative sleep: Deep sleep phases preserved for growth hormone.
• Optimized nutrients: Your proteins truly build muscle.

⚡ Champion performance and rapid recovery

• Titanic endurance.
• Quality sleep.
• Perfect hydration.
• Accelerated recovery.
