The effects of alcohol on bodybuilding and sports

Research Cyril Certain

Alcohol is often part of sports culture, especially in team sports. However, recent research highlights its detrimental effects on muscle recovery. A groundbreaking study reveals how alcohol consumption post-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 the overall functioning of your body, notably on energy production and protein synthesis.

Biological reactions when consuming 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 portion of your body’s resources, much like the entire factory coming to a halt to fix this small problem.

The body prioritizes eliminating alcohol, thus focusing less on other processes.

The liver primarily uses two enzymes to clean up. The first, alcohol dehydrogenase (ADH), transforms alcohol into a substance called acetaldehyde. But wait, there’s more! Acetaldehyde is then converted into acetate by a second enzyme, aldehyde dehydrogenase (ALDH). It’s like alcohol goes through two recycling stages before being completely eliminated. All this work for just one drink!

🍺 The Journey of Alcohol Discover how alcohol travels through your body and sabotages your muscle gains Click "Next" to follow the journey Previous Next See results Restart the journey Step 1: Alcohol enters the body When you drink alcohol, it immediately begins its journey through your body. The breakdown process will mobilize enormous resources from your body. 💡 The body treats alcohol as an absolute priority, putting aside all other processes like muscle building. Step 2: Passage through the stomach About 20% of the alcohol is absorbed directly in the stomach. The rest continues its path to the intestine. ⚡ Absorption is faster on an empty stomach. Eating before drinking slows down the process. Step 3: Absorption into the blood The remaining 80% of alcohol passes into the intestine and then directly into the blood. It then spreads throughout your body. 🚨 Alcohol reaches all your organs within minutes via the bloodstream. Step 4: Circulation throughout the body Alcohol now circulates everywhere: brain, muscles, liver, heart... It affects the functioning of every cell. ⚠️ Your reaction time decreases, your coordination is disrupted. Step 5: Impact on muscles Alcohol disrupts the mTOR pathway, essential for muscle growth. Muscle protein synthesis drops by 24 to 37%. 📉 It's as if 3 to 4 of your 10 reps are useless! Step 6: The liver at work Your liver uses two enzymes (ADH and ALDH) to transform alcohol: Ethanol → Acetaldehyde (toxic) → Acetate. This process creates an excess of NADH. ⏱️ The liver can only eliminate 0.15g of alcohol per hour per liter of blood. Step 7: Metabolic disruptions The excess of NADH disrupts the energy balance: glucose production blocked, fat utilization decreased, recovery slowed down. 🚫 Your body becomes an inefficient machine, unable to repair itself properly. 💪 Impact on Protein Synthesis -24 to -37% Alcohol drastically reduces your ability to build muscle. It's as if 3 to 4 of your 10 reps don't count! ⏱️ Elimination Time ≈ 7 hours For 1 standard drink. During all this time, your liver works at full capacity instead of supporting your muscle recovery. ⚠️ Disrupted Processes Energy production (excess NADH) Use of fat as fuel Glucose synthesis by the liver mTOR signaling (muscle growth) Recovery and tissue repair 📊 Comparison With alcohol Without alcohol

You might be wondering what impact all this has on your athlete’s body? Well, it turns out 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!) Additionally, to break down alcohol, your liver mobilizes an enzyme called cytochrome P450. The problem is, this enzyme is normally tasked with handling other substances. Result: it is no longer available to deal with certain medications or supplements you might be taking.

Alcool et sport impact performance

Why is alcohol bad for sports?

Alcohol is a real saboteur of your athletic 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-building supplements. Well, let us tell you, alcohol might be undoing all your efforts.

Let’s see together why this drink is so detrimental to your athletic 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. 📉 CRITICAL IMPACT Negative effects on performance Alcohol is a bit like putting low-quality fuel (or the wrong fuel) in your sports car's tank. Your overall performance takes a big hit! Studies have shown that even moderate alcohol consumption can reduce performance by 10 to 15%. Measured impact: 10 to 15% reduction in performance with moderate consumption Mechanism: Alcohol disrupts your energy metabolism and interferes with your liver's glucose production, leaving you short on fuel during exertion. 💧 HIGH IMPACT Impact on hydration and endurance Alcohol is a true hydration vampire. It increases urine production, which can dehydrate you quickly. Yet, 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. Consequence: Your ability to dissipate heat is compromised, causing you to overheat more quickly during exertion Comparison: Like a poorly maintained engine, your body becomes a less efficient machine ⚡ HIGH IMPACT Consequences on reaction time and coordination If you practice a sport that requires precision or quick reflexes, alcohol is your worst enemy. Even in small amounts, it slows your reaction time and disrupts your hand-eye coordination. Alcohol also affects your balance and proprioception (the perception of your body's position in space). Risk: Significant increase in injury risk, especially in sports with complex movements or rapid direction changes Side effect: Alcohol affects your judgment, pushing you to take risks you would normally avoid

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 muscle-building progress by slowing muscle growth and disrupting post-workout repair processes.

💪 The 3 mechanisms by which alcohol sabotages your muscles Alcohol after training directly compromises your muscle gains. Discover how it attacks your progress. 🧬 CRITICAL IMPACT Impact on muscle protein synthesis When you lift weights (heavy enough to make you grimace), you induce micro-tears in muscle fibers. This phenomenon, although perfectly normal, is also desirable because it is by repairing these micro-lesions, as well as responding to the generated metabolic stress, that your muscles become larger and stronger. Measured impact: Alcohol consumption can reduce muscle protein synthesis by up to 37%! Analogy: You see your set of 10 reps? It's like you're only doing 6 or 7, without increasing the weights! Mechanism: Alcohol interferes with the mTOR pathway, which plays a crucial role in muscle growth (imagine mTOR as the conductor of your gains, and alcohol as a noisy spectator disrupting the concert) 🔄 HIGH IMPACT Effects on muscle recovery After exertion, your body needs to recover. But alcohol, a true saboteur, disrupts this process. It increases the production of cortisol, the stress hormone, which can accelerate the breakdown of muscle proteins. Alcohol dehydrates your body, which also slows tissue repair and increases soreness. Double impact: Increased cortisol (catabolic hormone) + dehydration = compromised recovery Myth: No, alcohol does not help you sleep better. On the contrary, it disrupts restorative sleep. We think we fall asleep better but it's not the case. Sleep is crucial for the release of anabolic hormones (testosterone and growth hormone). 📈 HIGH IMPACT Consequences on muscle hypertrophy Muscle hypertrophy, that is, the increase in the size of your muscles, is probably one of your main goals in bodybuilding. Unfortunately, alcohol is a real hindrance to this process. By disrupting protein synthesis and slowing recovery, it limits your ability to build muscle mass. Overall result: All the mechanisms mentioned above converge to a single result → limitation of muscle growth Key question: Ok, alcohol is bad when you're a bodybuilding practitioner, but you may be wondering how much is really problematic... ⚠️ To remember: Alcohol after training creates a triple destructive effect: it blocks muscle building (-37% protein synthesis), slows recovery (cortisol + dehydration), and disrupts your restorative sleep. It's the number 1 enemy of your gains!

How many drinks in bodybuilding and sports?

📊 What studies teach us Scientific work (see below in the article) in this field reveals that alcohol interferes with muscle growth processes, even at relatively low doses. For example, some studies have observed a decrease in muscle protein synthesis of up to 30% after post-workout alcohol consumption. 💡 Research context: Most studies have focused on consumption equivalent to "binge drinking" in athletes, or about 1 to 1.5g of alcohol per kg of body weight. To give you an idea, this would represent about 5 to 8 standard drinks for an 80kg man. 📈 A dose-dependent relationship The effects of alcohol on your muscles follow a dose-dependent relationship. In other words: 📊 Cumulative effect The more you drink, the more the negative effects accumulate. 🔬 Impact from small doses Even small amounts can disrupt the cellular signals involved in muscle building. 🚨 Binge drinking = disaster Episodes of excessive drinking are particularly damaging to your gains. ℹ️ Important note: These effects may vary from person to person. Factors such as your genetics, gender, or individual tolerance to alcohol come into play. 🎯 How to reconcile sports and social life without sabotaging your gains? To limit the negative effects of alcohol on your sports performance, moderation and timing are essential. Here are some practical tips to help you find a balance between your social life and your sports goals: 1️⃣ Strict limit Maximum 1 drink on training days, if you choose (even after this article) to drink. ⏱️ Crucial timing Avoid alcohol in the 3-4 hours following your workout, this is the crucial recovery period. 💧 Hydration If you drink, alternate with water to stay hydrated and slow down alcohol absorption. 🍽️ Slowed absorption Eat before and during alcohol consumption to slow its absorption. 🍺 Strategic choice Favor low-alcohol drinks. 📅 Planning Plan your evenings on rest days or away from important competitions. 🚫 Periods of abstinence Plan periods of abstinence, especially before competitions or intensive training phases. 🏆 Don't forget: If you want to be the best (BE A 10), forget alcohol.
