Is Nole Cakes' stellar tennis year linked to a CVAC space pod???
The Wall Street Journal reports that [Novak] Djokovic has been spending time in a"rare, $75,000, egg-shaped, bobsled-sized pressure chamber" since last year's U.S. Open. The pod, made by a company called CVAC, is said to help stimulate vigorous exercise and improves athletic performance by increasing circulation, adding oxygen-rich blood cells to the body and expelling lactic acid.
The CVAC Pod is fancier than the hyperbaric chambers you've probably heard about; it stimulates high altitude training to compress muscles using a vacuum pump and computer-controlled valves. Unlike other contraptions, CVAC say the conditions in its pod can be adapted for various training purposes.
In terms of helping the body absorb oxygen, the pod is claimed to be twice as effective as blood doping. Better yet, it's infinitely more legal. The World Anti-Doping Agency has not banned these types of oxygen tents and pods even though it says they violate "the spirit of sport." Further testing is being done to determine whether devices like CVAC's pod will continue to be approved for use.
