According to published Sports Medicine of Australia, 88% of adolescent girls who practice physical exercise not used a bra according to its size, probably ignorance of how choose the BRA size is the reason to use a suitable fastener.

It showed by making them respond to that group of teenagers a simple test with questions about setting the BRA that 85% of these adolescents did not have adequate knowledge of how to properly choose size and BRA fit.

Why use an extra attachment to run?

The breast of the woman has no anatomical structures that hold it during the exercise. It consists primarily of fatty and glandular tissue, i.e. There are no muscles that hold it, for this reason the use of a good bra is essential so that all the weight falls not only on the torso and your chest vertical oscillation is reduced while you run with opinion of recipesinthebox.

The weight of the chest while running

A size 100 d chest can be 600 grams for chest, i.e. 1.2 kg pulling down from the torso. It is easy ito understand to keep that weight on the front of the torso posture at rest overload your back and neck.

Your chest may be more or less heavy depending on the size, and in some cases the weight of the breast at rest, you can force to adopt a stooped posture.

The position of the trunk while running is essential to run efficiently to make the least effort to move faster. Run with trunk curved not only negatively affects your race performance if not that may cause neck pain shoulders, back and arms.

The movement of the chest while running

While you run the chest moves about 12 cm up and down with each stride. This movement assumes that for each km the chest moves about 60-90 metres above below. With a conventional BRA, the chest is about 9 cm and with a bra sports movement is reduced to 4 cm for stride.

In the vertical movement of the breast when you run, the weight that supports the back with each stride increases considerably, why a sports bra not only has to hold if not that also has support the breast.

Excessive movement of the chest to run sometimes represents a barrier to practice running because it is uncomfortable from the biomechanical point of view and from the social point of view.

How much restraint do you need?

The subject you need to run will depend on the age and the size of your chest.

Age: the female breast is glandular tissue and adipose tissue. There is no specific structures that hold it. Fatty and glandular tissue is only attached to the skin covering it over. With age inevitably the skin becomes less smooth, so as the years pass you’ll need more restraint.

Bra size: Large chest is heavy and requires greater restraint.

Type of exercise: the vertical oscillation of your chest will be greater as you increase the pace of the race. Depending on the pace and size of your chest you’ll carry one type or another bra.
