1 The effect of drinking on fitness affects muscle growth. Long-term drinking will reduce the synthesis of protein in human body and reduce muscle development. And short-term drinking will hinder muscle growth.

Drinking will delay the recovery of sore muscles. Alcohol is a toxin, which spreads to every organ and tissue in the body through blood. Causes dehydration and slows down the body's healing ability.

Affect sleep In order to build bigger and stronger muscles, after training, your body needs rest to repair. Alcohol can affect sleep and deprive the body of a very precious chemical-growth hormone.

Human growth hormone is an important part of the program to promote muscle growth and repair. Enough growth hormone can make muscles grow bigger and stronger.

Alcohol that affects testosterone can reduce the secretion of human growth hormone by as much as 70%. In addition, when there is alcohol in the body, it will cause the liver to produce a hormone harmful to testosterone. Testosterone is an indispensable hormone in muscle development and recovery.

Alcohol will exhaust your body's energy source. Once alcohol is absorbed through the stomach and small intestine and finally enters your cells, it will disturb the water balance in muscle cells, thus affecting the ability to produce energy (adenosine triphosphate -ATP). ATP is the most direct energy source for muscle contraction.

Drinking alcohol will accumulate more fatty alcohol, which is of little nutritional value to human body, and the high calorie contained in alcohol will not be converted into liver sugar. The body regards these calories as fat, which will convert the sugar in alcohol into fat, so the calories in wine are not a good energy source during exercise.
