Consider only from the perspective of body structure
It’s simple. Mainly because of estrogen. One of the effects of estrogen: promote calcium salt deposition. Calcium salt deposition will promote the closure of the epiphysis. Epiphysis is the factor that allows minors to grow taller. When the epiphysis is closed, height development stops. The ovaries of adolescent women begin to secrete estrogen in large quantities, and women begin to establish a menstrual cycle. At this time, the closure of the epiphyses begins to accelerate. This is why the height of most girls is gradually surpassed by boys during adolescence. Second: Promote fat accumulation. Estrogen promotes the accumulation of fat in the buttocks and thighs. In theory, the average body fat rate of women is higher than that of men with the same diet and exercise amount. Third: In menopausal women, estrogen retreats, calcium salt deposition elements are weakened, and osteoporosis is more likely to occur. In addition, male androgens also have the function of promoting muscle development. Therefore, in terms of physique, men are generally taller and muscular than women under the same diet. It’s that simple. This is science and has nothing to do with discrimination against women.
Here is the easiest content: muscle mass
If in the street, a woman meets a man 10cm taller than herself. Both are of standard weight, so women will be 10% lighter than men
If the male muscle mass is 1, then the female muscle mass is 0.90.26/0.35=0.6686. It is also 170cm tall, which is considered short among men and tall among women. The standard weight of men is (170-80)70%=63kg. The standard weight of women is (170-70)60%=60kg. The normal value of female muscle rate is 25-27%, and the normal value of male is 30%-40%. The median is 26% for women and 35% for men 630.35=22.5kg 60*0.26=15.6kg
do you understand? The same height is 170, the same is the standard weight standard muscle rate, the muscle weight of women is 6.9kg lower than that of men.
The Juventus player Cristiano Ronaldo, known for his self-discipline and strength, has a muscle rate of 50% and a weight of 80 kg. Without the 6.9 kg of muscle, it is a little bit higher than the upper limit of the average male muscle rate. And this is under the premise of compulsory equating the height of men and women. According to the “Report on Nutrition and Chronic Disease Status of Chinese Residents (2020)”, the average height of Chinese men and women aged 18-44 are 169.7 cm and 158 cm respectively. According to the above algorithm, the average muscle weight difference between men and women is 8.25 kg.
