High-technology suits can increase one's swimming speed by around 4 percent. [1] Other studies suggest that high tech suits are able to reduce drag by around 4–6% and decrease energy cost by a similar amount. Other studies show evidence that in 50-meter races, these suits result in times that are approximately 0.5 seconds faster. [13]
A limitation of analog timekeeping was the technology's inability to reliably record times accurately below one tenth (0.1) of a second. [3] In 1967, the Omega company of Switzerland developed the first electronic timing system for swimming that attempted to coordinate the physical the recorded time.
Compression stockings are elastic compression garments worn around the leg, compressing the limb. This reduces the diameter of distended veins and increases venous blood flow velocity and valve effectiveness. Compression therapy helps decrease venous pressure, prevents venous stasis and impairments of venous walls, and relieves heavy and aching ...
Many of the world records in swimming were established by swimmers wearing bodysuits or suits made of polyurethane or other non-textile materials allowed in the race pool from February 2008 until December 2009. These suits seemed to improve the performance for top athletes, especially those with larger physiques.
Compression garments worn on the legs can help prevent deep vein thrombosis and reduce swelling, especially while traveling. Compression can also be used for post surgeries, to help with the healing process. Garment usage varies per patient but can be worn up to a year. There is also second stage compression garments, that are every day wear.
The Weissman score is a performance metric for lossless compression applications. It was developed by Tsachy Weissman, a professor at Stanford University, and Vinith Misra, a graduate student, at the request of producers for HBO's television series Silicon Valley, a television show about a fictional tech start-up working on a data compression algorithm.
