There’s no question about it. Alcohol and athletics don’t mix if you want optimal recovery, which is critical to reaching your performance and fitness goals.

Unfortunately, too many sports have created an entire culture based around drinking for fans and athletes alike. In fact, binge drinking is so prevalent in sports that studies suggest that athletes are more likely than the general population to drink in excess (1, 2).

Alcohol consumption can directly affect the processes of recovery in the hours after exercise. Plus, indirectly, it can alter your eating and resting patterns for even longer.

Recovery Interrupted

Remember that the process of athletic recovery starts immediately after intense exercise. Those initial hours after exercise are a critical time that can affect how long it takes to recover overall and any longer-term performance adaptations.

Feeding the body the right nutrients at the right time helps to restore fuel supplies, promote hydration, and enhance muscle building (3). The actual process of building muscle (muscle protein synthesis) is largely responsible for repair and adaptation after exercise (4). It’s why consuming high-quality protein soon after exercise and every three to four hours afterward is shown to maximize the anabolic response in skeletal muscle (5).

When you consume alcohol, you interrupt the process, limiting your capacity for muscle rebuilding and increasing the time it takes you to recover. Alcohol can also affect muscle fuel supplies, increase your risk for injury, and affect your sleep, which is essential for recovery. Here’s what the scientific literature has found happens when you have too much to drink:

  • You reduce fuel supplies. Fuel supplies are affected because alcohol decreases the re-synthesis of muscle glycogen. These stored carbohydrates in muscle act as one of your main types of fuel during training (6). Athletes who drink also often don’t get enough carbohydrates to meet recommendations for optimal recovery (6).
  • You increase risk of injury. A hangover the next day can ruin performance, but research shows that drinking roughly as little as four beers the night before training can also increase your risk of injury (7).
  • You lose valuable sleep. A night of heavy drinking can reduce sleep by one to three hours and is associated with a reduction in less power output the morning after (8). The lack of sleep can delay full recovery for as much as two days.
  • You impair your anabolic response. The effect of alcohol on protein synthesis is perhaps the most concerning for athletes. Alcohol itself suppresses the anabolic response in muscle and can significantly impair recovery and adaptation to training (9).

Ultimately, all of these effects together can make training useless if alcohol is used too frequently. So while you may enjoy a few drinks here and there, keep in mind that alcohol can be detrimental to performance, and should be limited if used at all.
