Blonde Girl Wearing Swimsuit In The Shower

In July 2009, FINA voted to ban non-textile (non-woven) swimsuits in competitive events from 2010. The new policy was implemented to combat the issues associated with performance enhancing costumes, hindering the ability to accurately measure the performance of swimmers. Subsequently, the new ruling states that men's swimsuits may maximally cover the area from the navel to the knee, and women's' counterparts from the shoulder to the knee.
Some swimmers use a specialized training suit called drag suits to artificially increase drag during practice. Drag suits are swimwear with an outer layer of looser fabric - often mesh or nylon - to increase resistance against the water and build up the swimmer's endurance. They come in a variety of styles, but most resemble a looser fitting square-cut or swim brief.
In recent years, more people are swimming for the health benefits of fitness and weight loss. The proper swimwear and googles are important for health enthusiasts, also, to prevent rashes and skin irritation.
