Many exercisers have heard of hormones, and even have "evil thoughts", thinking that hormones are a substance, as if they are somewhat related to "above", what is it? What does it have to do with fitness training?
Hormone is a transliteration of the word, actually the word Hormone, a transliteration of hormones.
It plays an important regulatory role in the metabolism, growth, development and reproduction of the body, and is an important substance in our lives.
If you have the heart to further understand the mechanism of human muscle growth, then you can't help but know the relationship between some important hormones and training and diet, which will help everyone regulate training and diet, so that we can increase muscle and lose fat more scientifically!
1. Pancreas
Carbohydrates are the body's main source of energy, if the blood contains too much carbide - high blood sugar levels, the body will be regulated by hormones, and vice versa, the two hormones involved are insulin and glycogen.
insulin
Insulin helps regulate blood sugar and energy levels, because after eating, digested food becomes glucose, amino acids, and fatty acids, and enters the bloodstream through the small intestine. When the pancreas detects an increase in blood sugar and other nutrient levels, it releases insulin, making it easier for muscle cells, adipose tissue and liver cells to absorb these nutrients and convert them into liver sugar and fat for storage. At the same time, under the influence of insulin, the body stops decomposing liver sugar and fat. So you can understand why slimming and bodybuilding friends should not eat sweet things or foods with high GI values!
Glycosyl
The role of glycosin is just the opposite of insulin, which raises blood sugar levels by converting liver sugar into glucose, so that blood sugar levels drop a few hours after meals or after exercise, at which point glycosyl is released to break down liver sugar.
2. Adrenal glands
Epinephrine and norepinephrine
Adrenaline and norepinephrine are made by the adrenal glands, hormones that put the body in a state of readiness in order to fight or escape. These hormones react to the body in the following ways:
■ Increase heart rate
■ Raise blood sugar levels
■ Flowing blood from non-vital organs into vital tissues (people become cold when they are scared or nervous, because the blood is transferred to large muscles)
■ let the airway open
There have been many news reports that when a mother sees a child in danger, she will suddenly become infinitely powerful and can lift a heavy decadent tile to rescue the child, which is largely because the adrenaline makes the mother's physical strength explode instantly.
Cortisol
Cortisol breaks down substances as an energy source for the body, and when exposed to stress, cortisol is released to break down carbohydrates, proteins and fats.
Therefore, to avoid high cortisol concentrations and break down muscles, the body must have adequate sleep, balanced nutrition, and avoid excessive stress and excessive training.
Therefore, never overtrain, otherwise it will only accelerate muscle breakdown.
3. Estrogen
Estrogen affects the amount of fat in the buttocks, lower back and thighs, as well as a woman's menstrual period. Women's estrogen levels are much higher than men's, so it is difficult for women to gain the same muscle mass as men under the influence of low testicle ketone and high estrogen.
4. Pituitary gland and thyroid gland
Growth hormones
Growth hormone allows muscles and bones to grow and boost immunity. When the body's testosterone levels rise, during deep sleep, and after weight training and strenuous exercise, the pituitary gland releases growth hormone to accelerate the growth of body tissues. Therefore, training and adequate sleep are very important for muscle growth.
Thyroid hormones
The thyroid gland is located in the neck, through which the pituitary gland secretes thyroid hormones to regulate the body's metabolism, so the body's various metabolic functions, such as the synthesis and decomposition of carbohydrates, fats, proteins, as well as body temperature, heartbeat and speed of breathing, are affected by thyroid hormones. If the body's thyroid hormone levels are too low, it can lead to problems such as tiredness, depression and obesity.
The above is the role of some hormones, if you equate it with testosterone, this is too narrow to understand!
