Want to grow taller, restricted by congenital and acquired factors:
Acquired factors should not only pay attention to exercise, but also combine the comprehensive effects of diet, sleep, mood, growth hormone and season. 17 years old, you can see if there is any increase after one or two months of exercise. It's so easy! Those heightening products are useless! Most people can't tell for a year or so. In addition, it should be noted that no matter whether the amount of exercise is small or large, the height will not increase. The former is not stimulated enough, and the latter is extremely weak, which hinders growth. The success of the increase depends on the correct combination of different sports forms. People in the developmental stage are not recommended to do upper limb muscle training, such as fitness, push-ups, sit-ups and other anaerobic exercises, which have an impact on height; We should strengthen jumping, stretching and hanging heavy objects, such as playing basketball, skipping rope, volleyball and pull-ups.
You 17 years old are at the third peak of development. Hormone secretion is still strong, and your body begins to develop from vertical to horizontal. You must seize the last prime time, it will be difficult to grow up after 20 years old. Pay attention to exercise. Time waits for no one, everything depends on yourself!
Let's make a scientific analysis: how long can it last?
You may eventually grow to a height of about 173cm. Why?
According to the statistical principle, your father is 1, 72, your mother is 1, 58, and your parents are average in height, that is, the average height of your parents in your home is 165cm, and the height level is average, that is, their height and the average height of their parents in the average family are 178cm. At the same time, it also means that the genetic factors of the average height of your parents should be concentrated on the genetic factors of the average height of your parents in general families, that is, to the average height of 178cm, and make a staged regression, that is, an increasing trend. Your parents' genetic factors should be strengthened in height, and you have parents' genetic factors. So, you must be taller than them, even higher. Now you are 17 years old, and your height is about 167cm, which has exceeded the average height of your parents 165cm, and you are converging to the average height of your parents in ordinary families 178cm, and your growth space is about 1 1cm. However, you are greatly influenced by your parents' genetic factors, and the space for height growth is narrowed, which may eventually grow to about 173cm. Generally speaking, the child's height = father's height (cm)+ mother's height (cm)× 1.08, and then divided by 2, floating up and down a few centimeters. Generally speaking, there are about 75% boys, so this formula can't escape. (According to the formula, your calculated height is178.2cm.. )
Although genetic factors account for 70%, acquired factors are very important and can be changed: act quickly and take the initiative! The facts speak for themselves, and time waits for no one! If you don't take the initiative to try, you will regret it all your life!
If you want to get taller, you can do this:
1, can't do muscle training, such as push-ups, sit-ups, and other anaerobic exercises; Don't do weight-bearing exercises, such as lifting weights. Don't overdo your activities, don't be too tired, such as marathon running and long-distance skiing. Excessive fatigue can also hinder growth.
2. Have an orderly work and rest every day. Don't stay up late. Try to sleep at 10 at night, because 10 is the peak of growth hormone secretion at 2 am. It starts after 40 minutes of deep sleep and secretes several times a night. It is the best time to grow taller. Taking a nap at night is easy to affect sleep time and fall asleep at night.
3, can't smoke, drink, watch pornography-! Don't eat too much or take drugs or food containing sex hormones by mistake, or you will be precocious! Such as royal jelly, drinks containing hormones, etc. ;
4, don't be too angry, thinking, have a short-term goal every day, and a good mood is also conducive to the growth and development of height.
5, balanced nutrition, not picky eaters, hunger strikes, eating less, overeating. Meat and vegetables are indispensable, at least one fruit a day; Dieting to lose weight will affect the growth of height and damage learning energy.
6, it is best to 1 liter of milk every day, at least 500 ml of milk, remember, high-calcium pure milk, drinking a cup of hot milk before going to bed, can promote sleep and growth hormone secretion;
7, moderate "self-comfort", this must, stimulate some hormones, regulate emotional endocrine, according to the doctor's advice, the secretion of many hormones in the human body dominates or affects our growth and development, such as growth hormone, sex hormone, thyroxine, parathyroid hormone, insulin and so on. ;
8. See a doctor, check the bone age, see if the bone line is closed, or check what trace elements are missing, such as calcium, zinc and iron.
9. Get more sunshine, because solar energy can convert nutrients in the human body into vitamin D, thus helping calcium to be effectively absorbed in the human body, and vitamin D is rarely taken directly from food;
10, pay attention to the seasonal increase. Spring and autumn are the fastest growing seasons, especially in March, April and May, and May is the longest month. A three-dimensional height increase plan should be adopted: diet and exercise should be carried out simultaneously;
1 1, eat less sugar, salt and foods with more artificial hormone additives. Too much sugar and salt such as cola, dessert and KFC chicken wings will hinder the absorption of calcium by bones;
12, insist on two hours of moderate exercise every day, because exercise can promote the secretion of growth hormone and accelerate the growth of bone tissue, which is beneficial to human body length. It is recommended to play basketball or jump rope for 30 to 40 minutes each time; According to the research, 1-2 hours of continuous exercise can obviously increase the content of growth hormone in a certain period of time, and the tubular bone growth area is also active, thus increasing the height;
13, eat more animal livers, supplement some cod liver oil appropriately, and take some drugs for treating ascaris, such as Shikeqing;
14, swimming in a safe swimming pool every week, kicking your feet hard and doing stretching exercises, probably tired from swimming;
15, don't press your spine, hold your chest out. A person's sitting posture, standing posture and walking posture will also have an impact on his height. People who walk, stand or sit with their heads held high usually grow taller easily. Because the spine is often tired, it will affect the brain hormones to the body bones, and it is difficult to grow taller;
16, don't worry about making more friends of the same sex or the same age. Have fun and stick to it.
