The first sports bras were designed to help reduce breast motion that occurs during exercise or playing sports. Since the breasts are held by ligaments that don't provide a substantial amount of support, breast movement is extremely difficult to control without bras designed specifically for exercise and playing sports.
Contrary to conventional bras they are more durable and provide greater support to the chest during training, thus decreasing the chance of damage to the delicate tissues. It is a good option to purchase best womens sports bra from an online site to protect your breasts during sports activity.
When exercising, if the breasts don't have support, they can move without restriction with each move that the human body makes. An excellent analogy is the bobbing the ponytail of a woman when doing an activity like running. Most women, especially those with larger breasts are able to find this kind of movement extremely painful. The size and the weight of women's breasts are associated with the frequency of discomfort.
The sports bras can be classified into two categories: the encapsulation type that has cups that are molded and compression bras that restrict movement by flattering breasts. Encapsulation is typically better for lessening discomfort, but some women prefer compression models that are usually more stylish because they are intended to be used as clothing.
