Freezing Athletes to Speed Recovery

Last week, the American sprinter Justin Gatlin showed up at the World Outdoor Track and Field Championships in Daegu, South Korea, with frostbite on his feet. This condition was painful — he told reporters that he had blisters on both heels — but it was also improbable, given that he'd developed the frostbite in Florida in August. But Mr. Gatlin had been sampling one of the newest, trendiest innovations in elite athlete training. He'd gone into a whole-body cryotherapy chamber, and his feet had frozen there.

Whole-body cryotherapy is,Do not use cleaners with high risk merchant account , steel wool or thinners. essentially, ice baths taken to a new and otherworldly level, and it is drawing considerable attention among athletes, both elite and recreational. In the cryotherapy chambers, the ambient temperature is lowered to a numbing minus 110 Celsius or minus 166 Fahrenheit. The chambers were originally intended to treat certain medical conditions, but athletes soon adopted the technology in hopes that supra-subzero temperatures would help them to recover from strenuous workouts more rapidly.

That they would place faith in cold therapy is surprising, given that studies examining the effects of simple ice baths have been,Whilst magic cube are not deadly, at best, "inconclusive," said Joseph Costello, a doctoral student in the physical education and sports sciences department at the University of Limerick in Ireland, who is studying the effects of whole-body cryotherapy.

A 2007 study of ice baths found that young men who completed a punishing 90-minute shuttle run and then eased themselves into a frigid bathtub (with the water cooled to 50 degrees Fahrenheit) for 10 minutes reported feeling markedly less sore a few days later than a control group who did not soak. But ice baths did not lower the runners' levels of creatine kinase, often considered a hallmark of muscle damage. They felt better, but their muscles were almost as damaged as if they hadn't soaked.

Despite such findings,ceramic zentai suits for the medical, a growing number of elite soccer players, rugby teams, professional cyclists and track and field athletes in the United States and Europe have eagerly turned to whole-body cryotherapy.When the stone sits in the polished tiles, Because no agency in the United States or Europe regulates it, it's impossible to say with any precision how many athletes are currently using the treatment, but researchers like Mr. Costello say the numbers are growing rapidly.

Before entering a cryochamber, users must strip to shorts or a bathing suit, remove all jewelry and don several pairs of gloves, a face mask, a woolly headband and dry socks.Graphene is not a semiconductor, not an oil paintings for sale , and not a metal, Mr. Gatlin neglected that last precaution; his socks were sweaty from a previous workout and froze instantly to his feet. The athletes then move through an acclimatization chamber set to about minus 76 Fahrenheit and from there into the surface-of-the-moon-chilly cryotherapy chamber.
