Whether it's gaining muscle or losing weight,

Smoking will affect your training!

But to be honest, I've seen some.

Those who practice a lot also have the habit of smoking.

But basically this is already a great god level!

They will also tell you,

Try not to smoke!

Smoking has a great influence on fitness!

Effect of smoking on muscle growth

Smoking will affect muscle growth and affect the endurance and strength of our bodies. We all know that the main body of muscle is composed of protein and carbohydrates, and its density is three times that of fat. The process of muscle gain requires a lot of nutrition intake, while the process of muscle exercise requires a lot of energy and oxygen. However, after you smoke or smoke secondhand smoke, because hemoglobin in our blood is more easily combined with carbon monoxide, our muscles can't get enough oxygen supply in the blood at first, and the metabolism of muscle cells will be hindered. Secondly, the chemical components in smoke will stimulate blood vessels to contract, leading to the loss of nutrients in our muscles. Once we lose our nutritional supplement, even if you practice hard, it won't help.

In addition, nicotine in cigarettes will increase the heart rate by at least 30%, raise blood pressure, and make blood unable to effectively supply the muscles of the whole body, so that we feel powerless during exercise and our bodies will become weaker and weaker.

Influence of smoking on weight loss

Smoking can make people fat. We must first define a concept, that is, what is fat. For a long time, represented by physical examination in colleges and universities, people have always taken the body mass index value (the number obtained by dividing the weight and kilograms by the square of the height and meters) as the measurement standard. In fact, this is reasonable in the case of balanced nutrition, but now many of us are overnourished and lack exercise, so it is unreasonable to use the body mass index value to measure whether a person is fat or not. For example, a muscular man with a height of 180 cm and a weight of 170 kg and a fat man with a height of 180 cm and a weight of 170 kg have the same body mass index, but we all know who is fat and who is not. Why is this? Because the body mass index only reflects the rationality of height and weight, but it cannot reflect the composition of our weight.

The density of muscle is three times that of fat, which means that the volume of muscle is one third of that of fat under the same mass. Therefore, the body mass index can't reflect whether a person is obese, but the data that can best reflect the degree of obesity is the body fat rate, that is, the percentage of body fat weight to body weight. Having said that, I actually want to refute a survey result. Regarding whether smoking can make people fat or thin, there are actually two results, one is the conclusion of getting fat and the other is the conclusion of getting thin. In fact, the former is based on body fat rate, while the latter is based on weight. As mentioned above, smoking will affect the growth of muscles. When the insulin level and renal function are normal, the nutrients that cannot be absorbed by the muscles of smokers or secondhand smokers will eventually become fat and be stored.

At the same time, our bodies are adaptive, and everything is "enough", including muscles. Without the strength of lifting iron in the gym, muscles that have not been nourished for a long time will slowly decompose, and the decomposed organic matter will be stored as fat, and water will be excreted, which is one of the reasons why smokers have more loose skin. To sum up, the body fat rate of smokers or passive smokers will increase. There are too many "fake skinny people" in real life, and the increase of body fat rate is to gain weight.

Effect of smoking on breathing

As we all know, breathing is very important for a bodybuilder. Different movements need different breathing methods, and different training categories need different breathing intensities. However, the tar in the smoke will cover or even destroy our alveoli, resulting in a decrease in the amount of oxygen absorbed by hemoglobin and a decrease in its utilization rate. At the same time, our body's "self-adaptation" is to exclude these foreign smoke tar from secreting phlegm, which further reduces the amount of oxygen we inhale. I don't need to say more about the harm of hypoxia to our health.

Effect of smoking on testosterone

The chemicals in smoke are quite complicated, and the second-hand smoke has a lot of chemical reactions due to its full contact with air, and the amount of chemicals contained in it has not been determined so far. But research shows that at least nicotine will directly affect the regulation of human gonadal hormones and reduce the level of testosterone in the body. Testosterone can promote muscle synthesis, and low levels of testosterone will have a certain impact on fitness. At the same time, the long-term decrease of androgen testosterone level also means sexual dysfunction and impotence. So quit smoking quickly! If you have been devastated by secondhand smoke, please take action to protect your health!

I know everything, but I just can't quit, okay?

If you must smoke, try to change the smoking time. Don't smoke for an hour or two before fitness, and don't smoke during breaks between groups. Don't smoke immediately after fitness, wait until an hour or two after fitness. This will still have a great impact on fitness, but it will be less. If you can, you'd better quit smoking!

Give ta to whoever you think of. For the sake of ta's health, help ta control smoking as much as possible, and then join the fitness with ta to start meat abuse and show love ~
