It’s easy to see why NHL teams are taking this kind of test.
Players can’t play without oxygen or other breathing support.
So they’re getting checked by a team of divers, and those tests are usually done while they’re in a pool or underwater.
It’s a much safer way to test for airway issues.
But there are some risks associated with this testing.
In a study published last year, researchers found that the test can actually be harmful to players’ health.
The researchers said that breathing underwater is associated with a wide range of adverse health effects, including:• Heart damage• High blood pressure• Respiratory problems• Brain damage• A decreased ability to control breathing for short periods• Increased chance of getting an infection, such as pneumonia and pneumonia-like illness• Increased risk of respiratory failure• Increased likelihood of developing a cough or wheezeSource: NHL Players Association press releaseSource: USADA/NHL Players Association, 2017.
