Hormone is a transliteration word, but it is actually the word hormone, which is a transliteration of hormone. It plays an important role in regulating the metabolism, growth, development and reproduction of the body and is an important substance in our lives. If we understand the mechanism of human muscle growth, we will find the relationship between hormones and training and diet, which will help us gain muscle and lose fat more scientifically.
First, the pancreas
Carbohydrate is the main source of human energy. If the blood contains too much carbide and the blood sugar level is high, the body will regulate it through hormones, and vice versa. The two hormones involved are insulin and glucagon.
insulin
Insulin can help regulate the body's blood sugar and energy levels. When the pancreas detects an increase in blood sugar and other nutrients, it releases insulin, making it easier for muscle cells, adipose tissues and liver cells to absorb these nutrients and convert them into liver sugar and fat for storage. At the same time, under the action of insulin, the body stops decomposing liver sugar and fat. So friends who are slimming and bodybuilding, don't eat sweet things, and don't eat foods with high GI value (glycemic index)!
glucagon
Glucagon has the opposite effect to insulin, and improves blood sugar level by converting liver sugar into glucose. Therefore, the blood sugar level will drop after a meal or a few hours after exercise, and glucagon will be released to decompose liver sugar.
Second, the adrenal gland
Epinephrine and norepinephrine
The adrenal glands produce adrenaline and norepinephrine. These hormones prepare the body for battle. These hormones have the following reactions to the body:
■ Increase heart rate
■ Open the airway.
■ Improve blood sugar levels.
■ Make blood flow from non-important organs into important tissues.
There have been many news reports that when a mother saw that her child was in danger, she suddenly became strong and could lift heavy rubble to save her child. This is largely because adrenaline makes the mother's physical strength explode instantly.
Cortisol
Cortisol decomposing substance. When faced with stress, cortisol is released to break down carbohydrates, protein and fat. Therefore, to avoid excessive cortisol concentration and muscle decomposition, the body must have enough sleep, balanced nutrition, and avoid excessive stress and overtraining. So be careful not to overtraining, otherwise it will only accelerate muscle decomposition.
Third, genitals.
testosterone
Weight training and high-intensity exercise can stimulate testosterone secretion, especially after leg training. Testosterone is not only effective for men, but also very important for women, because its main function is to make tissues grow and repair, so testosterone is the main factor to increase muscle mass. This is why it is difficult for women to build big muscles, because they have little testosterone in their bodies.
estrogen
Estrogen can affect the amount of fat in buttocks, lower back and thighs, and also affect women's menstrual period. The estrogen level of women is much higher than that of men, so it is difficult for women to gain the same muscle mass as men under the influence of low testosterone and high estrogen.
4. Pituitary and thyroid gland
somatotropin
Growth hormone makes muscles and bones grow and improves immunity. When the body's testosterone level rises, during deep sleep, and after weight-bearing training and strenuous exercise, the pituitary gland will release growth hormone to accelerate the growth of body tissues. Therefore, training and adequate sleep are very important for muscle growth.
thyroid hormone
The thyroid gland is located in the neck, through which the pituitary gland secretes thyroid hormone and regulates human metabolism. Therefore, various metabolic functions of the body, such as the synthesis and decomposition of carbohydrates, fats and protein, as well as body temperature, heartbeat and respiratory rate, are all affected by thyroid hormones. If the level of thyroid hormone is too low, it will cause fatigue, depression and obesity.
These are the effects of some hormones. If we just equate it with testosterone, it will be too narrow to understand!
