Physical Excercise n Sports Bra for Girls

Sports Bra 4 Girls

Women wear Sports Bras for supporting their breasts during physical exercise. Around 50 percent of women experience pain and discomfort in their breast while exercising.  Sports bras are more robustly built than ordinary traditional bras because they are specially made to reduce the extra movement of women’s breast during exercise to lessen tenderness and alleviate probable damage to chest tissues and muscles. The sports bras are specifically designed to help large breasted women to participate in sporting activities because their larger breasts are heavier and move more heavily during exercise which causes greater damage and pain to them. Some outdoor/indoor activities like yoga, walking or gardening causes only slight movement whereas power walking, cycling cause moderate movement of the breasts. However more strenuous sports like jogging, soccer, tennis and horseback riding etc cause greater movement of the breasts and need tighter and better control for preventing pain or damage.  The need for a Sport Bra for girls was felt when women complained of soreness and pain while jogging because of the constant jiggling of their breasts. The intensity of the pain varied according to the size of the breasts because the heavier or large the breasts, the greater the discomfort and pain. In 2007 a comprehensive study by the University of Portsmouth carried out which carried studies the movement of women’s breasts who were wearing different types of bras with cup sizes of DD, E, FF, G, H, HH, J and JJ. Researchers found that women’s breasts moved in three directions, vertically, horizontally and laterally. Motion studies show that when women run, 50 p% or more of the breast’s movement is vertical, 22% side to side and 27% in and out.   The researchers initially used two different bras, and some women were even photographed without wearing any bra. It was obvious that breast movement was considerably reduced when women wore bras and the movement was even more reduced when the women wore Sports Bras. Women who used the Sports Bra reported the least discomfort and pain even after exercising for two hours or more continuously. The study also revealed that women who wore Sports Bra that enclosed their breasts in individually molded cups suffered less discomfort than compression type bras which press the breast close to the women’s body.

Measurements : Breast Size and Weight

In the same way that a dress is chosen according to the women’s measurements, so a Sport Bra is chosen according to the size and weight of the woman’s breasts. Buying the wrong size might do more damage than good because it will not provide the requisite support for the delicate breast tissue. The Sports Bra must be chosen according to the sports or other activity that will be carried on while wearing the Sport Bra. The perfect size must be chosen because the Sports Bra is made in different sizes. The most popular size of Sports Bra is 30-40 cup size A-HH. For acquiring the perfect size women must have their breast size measured by their supplier or the woman can carry out her own measurements and order from a wholesaler. Measurements can be carried out by placing a tape measure around the chest and making sure that the tape is level around the back. The measurements must be taken without a bra or the measurement could be a little smaller or larger than the original breasts. The first Sports Bra that was available in the market was the “Free Swing Tennis Bra” which was marketed by the Glamorise Foundations Inc in 1978. This was followed by the first generation exercise bra commonly known as a: jock-bra”. The introduction of the bra was because many women complained about their discomfort and pain when they exercised wearing a conventional bra. The jock-bra was invented because women needed a better alternative and a suggestion was made by a man that what women really needed to support their breasts from excessive was a jockstrap that men used to prevent damage to their testicles to prevent muscle tear. The inventors of the jock-bra initially experimented by sewing two jock straps together and called it a “jock-bra”. This jock-bra was an instant commercial success and was followed by specialty bras for different sports in accordance the amount of jiggling and movement of the breasts. The Sports Bra gained popularity among women, and many women with heavier breasts who were not participating in any sports or athletic activity because of tremendous soreness and pain that followed suddenly were active sports participants with the use of the Sports Bra because of the freedom it afforded them.

Sports Bra – Technology n Terminology 

Like any other commercial mass produced product, the Sports Bra has its own technology and terminology. A compression bar has elastic support fabrics so that the breasts are held close to the women’s body that basically is meant to reduce the amount of bounce of the women’s breasts. However, it produces a uni-boob look which some women do not like. Some women prefer the encapsulation bra over the compression because these bras are mode of molded semi-rigid cups to hold the women’s breasts. The molding of the cup in a precise manner and the way that it has been built into the bra controls the movements of the woman’s breast when she exercises and because the movement of the breast is controlled and restricted, women remain comfortable and free from soreness and pain. Many Sports bras are a combination of compression and encapsulation types for better supporting of breasts by rigidly their movements.  Some Sports bras are made of much stiffer components for holding up the breast and giving it an attractive shape. The stiff material used is mostly wire frame to support the weight of the breast. Straps are crisscrossed over the women’s shoulders act like a suspension cantilever because women who have large breasts prefer broader straps which do not stretch thereby making the breast look large and unattractive. Most A/B bras are made so that are worn by pulling them over the breasts because the band size and bust size are not the same which makes it difficult for the women to just wear it by pulling it one. Therefore most C/D DD bras have either a from or a back closing mechanism and to prevent rubbing against the breasts and the body the closure mechanism does not rub against the skin or cause any discomfort.

In 2010 a study was carried to determine the effect of the Sports bra on breast sport when the women is jogging or running and the objective of this study was to look into the different directions that the breasts moved, the velocity at which they move and the results with and without breast support while the woman was running and the amount of discomfort and pain the woman felt in both situations. The cups that were used were size 15 D and many women volunteered to participate in this study project. It was discovered that the violent swinging of the breasts  and the accompanying were  considerably reduced with the use of the Sports Bra because it controlled the swinging of the breasts in different directions. This proved that breast discomfort and pain were directly linked with the violent swinging of the breasts.

Another study was carried out in 2011 by a different research group studied unsupported breast swinging in different activities to study in which activity the breasts were displaced the most and  required the most support. The tests were carried out in different conditions using 21D cups and the activities varied from walking on a treadmill to fast jogging and running on the same treadmill. The researchers found that the right breast underwent greater displacement when moving at 15 KPH without any support. The breast moved at 15.8 cm. The results also proved that the greater the support of the breasts, the less the displacement or swinging took place in an encapsulation bra versus no bra. The result also showed greater displacements as the speed on the treadmill was increased. The experiment proved that at higher speeds of activity vertical breast displacement were the greatest but side to side and forwards and backwards movement still accounted for 50 percent of the total breast displacements. This obviously meant that the Sports bra should be made in a manner that focused mainly on vertical displacement but also concentrate on other aspects of breast movements. The study did not acquire any evidence that breast support requirements undergo changes with the increase in speed. It observed that designs should study very sports and the effect that they have on breast displacement. Studies also proved that sports bras must also consider the age of the woman and the different sizes of bras that are the best at a certain age. Studies have proved that the breasts of younger women move predominantly up and down whereas the breasts of older women tend to swing more sideways than up and down. This obviously suggests that the maxim “one fits all ages” is not applicable with sports bras so manufacturers must create specific and different sports bras for older women that will support the sideways movements of their breasts. With special bras created for older women they will be encouraged to participate more actively in sports and also to feel comfortable while doing so. Although the Sports bra exerts more pressure on the rib cage, it did not interfere with the women’s breathing.
