First, the influence of drinking on strength.
1. Alcohol can inhibit nerve excitability and even cause drowsiness. Muscle contractility is closely related to the degree of nerve excitement, because the degree of nerve excitement directly determines how much exercise units participate in muscle contraction, which is why there is a nitrogen pump to supplement it.
2. In addition, the digestion and metabolism of alcohol will discharge a lot of calcium, which is a very important ion to maintain the normal function of cells in the body. In addition, there is a place called "terminal pool" in the myotube system, which is specially used to store calcium. If you lack calcium, it will directly lead to a decline in exercise ability.
3. Long-term drinking will lead to fatigue, decreased exercise ability and even lethargy, which will directly affect the training intensity and fitness effect.
Second, the influence of drinking on bones
Calcium discharged from drinking will also directly affect bone health. In addition, long-term drinking may lead to disorder of lipid metabolism, proliferation and hypertrophy of adipocytes in femoral head and bone marrow, steatosis of bone cells, osteoporosis and so on.
Third, drinking affects recovery.
As we all know, alcohol hurts the stomach. The damage of gastric mucosa caused by alcohol will affect the absorption of nutrients, and the increase of strength and muscle dimension can not be separated from nutrition. In addition, the discharge of alcohol will be a burden to the body, which will directly reduce the hormone level of the body and affect the fitness effect.
Fourth, drinking alcohol leads to obesity.
1, many people know to drink less sugary drinks. In fact, alcohol contains more calories than sugary drinks. Every gram of alcohol produces about 7000 calories, while jogging for an hour consumes about 600-700 calories. Of course, there are individual differences in the absorption of alcohol, but the calories absorbed are definitely much more than the calories you jog for an hour.
2, in addition, drinking is basically eating and drinking. Alcohol will greatly increase your appetite, and before you know it, you will consume far more calories than you think. Eventually, excess heat will be converted into fat.
Extended data
Fitness is a kind of exercise, such as all kinds of unarmed aerobics, rhythmic gymnastics, rhythmic gymnastics, and all kinds of self-resistance movements. Gymnastics can enhance the strength, flexibility, endurance, coordination and control of all parts of the body, thus making the body strong. If you want to relieve stress, exercise at least three times a week.
Swimming, brisk walking, jogging, cycling and all aerobic exercises can exercise the heart. Aerobic exercise has many benefits: it can exercise the heart and lungs, enhance the function of the circulatory system, burn fat, increase vital capacity, lower blood pressure, and even prevent diabetes and reduce the occurrence of heart disease. The American College of Sports Medicine suggests that if you want to know whether the intensity of aerobic exercise is appropriate, you can test your heart rate to reach 60%-90% of the highest heart rate after exercise. If you want to lose weight through aerobic exercise, you can choose low to moderate exercise intensity and extend exercise time. This method consumes more calories. Exercise frequency is 3-5 times a week, 20-60 minutes each time. If you want to exercise your muscles, you can do weight lifting, gymnastics and other exercises that repeatedly stretch and flex your muscles. Muscle exercise can burn calories, enhance bone density, reduce the chance of injury, especially joint injury, and prevent osteoporosis. Before you lift weights, measure them. If you can lift eight times in a row, practice from this weight. When you can lift this weight 12 times in a row, try to increase the weight by 5%. Pay attention to lifting 8- 12 times in a row every exercise, so as to reach 70%-80% of the maximum endurance of muscles, and the exercise effect is good. 2-3 times a week, but avoid exercising the same group of muscles for two consecutive days to give the muscles sufficient recovery time.
