As much attention should be given to selecting a good plus size sports bra as is given to selecting any other important piece of athletic equipment. Besides the pain and discomfort from the lack of proper support, you may also be causing yourself permanent damage. The Coopers ligament from which the breasts are suspended can become permanently stretched causing the breast to sag. This condition is irreversible
A good plus size sports bra is designed to prevent discomfort and damage by minimizing movement, especially vertical movement. These bras differ from other bras in both type of material used, and design. Where regular bras are made with more emphasis on fashion, sports bras are designed more functionally to limit breast movement and displace moisture.
There are two main types of sports bras compression and encapsulated.
Compression sports bras tend to work better for smaller chested women, below a C cup. These bras reduce breast movement by compression or flattening the breasts against the chest wall.
Encapsulation sports bras are recommended for larger chested women, a C cup and above. These bras are designed to reduce movement by separating the breasts and supporting each one individually.
Some other design features which may be helpful are things such as strap design, material, seams, and fasteners. You will find the most support is provided by the cross-backed and T-back style straps. Materials with a higher percentage of spandex, 15% to 20% tend to give better support. Cup seams should be minimal to reduce chaffing. Also look for plush-backed hooks for added comfort.
Sports bras will begin to loose their elasticity over time and sould be replaced on average every 6 to 12 months. You can extend the life of your bra by hand washing and line drying.
