Playing lawn tennis is no joke; you need a lot of stamina and endurance to be on the top of the rankings. Serbian tennis star Novak Djokovic knows that too well as he tries every ritual he knows to ensure that lady luck is on his side. After his gluten-free diet, he has now turned his attention to a new secret weapon called a CVAC pod to boost his performance using simulating high altitude. The “$75,000 egg-shaped, bobsled-sized pressure chamber” is the brainchild of California-based CVAC Systems, which is limited to just 20 units and hasn’t been banned by any sports governing bodies yet.
The ambitious machine features a “computer-controlled valve and a vacuum pump to simulate high altitude and compress the muscles at rhythmic intervals“. The company says a 20 minute routine in the seven feet long, seven feet high, and 3 feet wide pod thrice a week is all you need to “boost athletic performance by improving circulation, boosting oxygen-rich red-blood cells, removing lactic acid, and possibly even stimulating mitochondrial biogenesis and stem-cell production“. The pressure, temperature, and air density in the CVAC pod can be adjusted to suit specific users. The one Djokovic has access to is owned by 38-year-old tennis pro Gordon Uehling III.
