Alcohol in Sports


Alcoholic is any liquid that contains alcohol. We usually call this the drink that contains ethyl alcohol (liquor).

The daily recommended dose of alcohol is one “serving” drink per day for adult women and two “servings” drinks per day for adult men, one “serving” drink for men and women over 65 years of age.

A “serving” drink is 1 glass of wine (140ml) or 1 can of beer (330ml) or 45ml of a drink with a high alcohol content, such as vodka or whiskey.

Alcohol can affect the adequate intake and absorption of nutrients.

All drinks have a diuretic effect, that is, they cause an increase in urine production and fluid excretion from the body because alcohol affects the production of hormones that regulate water retention in the kidneys.

Alcohol Abuse

1. Alcohol abuse due to its diuretic effect can lead to hyponatremia (low blood sodium), low phosphorus, low magnesium and low blood calcium. All of these minerals are electrolytes necessary for the proper functioning of our body.

2. Alcohol abuse causes a slowdown in metabolism and digestion and reduced absorption of nutrients from food.

It can also disrupt protein synthesis resulting in incomplete muscle formation, inhibit signals for protein building resulting in delayed protein formation and, by extension, muscle.

3. Alcohol abuse affects the hypothalamic-pituitary-gonadal axis system, resulting in lower testosterone levels, altered production of certain reproductive hormones, and reduced sperm production.

4. It also reduces growth hormone, resulting in negative effects on blood sugar maintenance and muscle and bone metabolism.

5. It creates an increase in body fat by forming triglycerides.


Consuming carbohydrates and proteins along with alcohol abuse has no benefit in preventing muscle breakdown in the body. It has a small benefit only in preventing the rapid absorption of alcohol by the body and slightly delaying its circulation in the blood.

Alcohol is not the best drink for improving strength or athletic performance.
Its consumption with caution will never cause problems in the body, while its abuse will significantly slow down the performance of athletes and if it becomes long-term it will cause more problems in the body (fatty liver infiltration, liver cirrhosis, cardiovascular diseases, infertility-testicular atrophy, cancer, gastritis, pancreatitis, depression, paranoia, polyneuropathy, dementia) than the temporary well-being it offers.
