Is sports underwear necessary?

 Many women are worried about whether they need to buy a sports underwear for doing sports. Some wonder whether they should wear sports underwear or not if they have small breasts. Besides, the sports underwear is not good-looking, when meeting a handsome guy and it can't set off their body without a bra.


First of all, sports underwear is designed to fight against the corresponding bad breast movement in sports. Generally speaking, when girls do any unsupported movement (such as running), they will cause three-dimensional breast movement: up and down, from inside to outside, and from one side to the other, that is, figure eight movement. Foreign research data show that every step a woman takes, the average breast movement is 9.08 cm. If the length of each step is 50cm, when you run 1km, your breast will also run 180m.

Breast does not have muscle, in fact, it relies on ligaments and surface skin to play a supporting role, and with the growth of age and external force, breast suspension ligament as the connective tissue supporting a pile of connective tissue (fat, breast), just like spring rope, pulling too often, the elasticity will become worse, and it will only become more and more elongated and relaxed. Only appropriate underwear and scientific sports can do it Help us fight this tendency. Moreover, if the exercise is not protected in place or not enough support, it may cause discomfort and damage of breast ligament. The injury and sagging are almost irreversible, so it is necessary to choose the proper exercise mode and appropriate protection mode.


So it doesn't matter whether the breast is small. In fact, regardless of the size of the cup, the breast will produce up, down, left, and right displacements in high-intensity sports such as running and aerobics. Even the A cup can still produce more than The movement of 4cm distance, and the sagging that this movement may produce is still irreversible. This matter has nothing to do with the size. In fact, men's breasts tend to sag when they get older. This is caused by the structure of the breast and has nothing to do with the size. Therefore, in addition to support, support or support for breasts during exercise, in addition to shock absorption or shock absorption, ordinary bras can only reduce chest vibrations by 38% during exercise, and suitable sports underwear can increase this value to 70% the above.


In addition to the above two common misunderstandings, other women are concerned about the beauty of wearing sports underwear. As for the breast shape, in fact, the high and thick cushion of ordinary underwear can set off the breast shape. However, during sports, cotton underwear and heavy cushion can not provide the necessary support, but cause the breast to be stuffy in the humid environment for a long time because of sweating and airtight. In addition, as for the appearance of sports underwear, first of all, the sports underwear is very fashionable now. There are many beautiful pictures and videos on YOUTUBE and INS about sport underwear.
