The NFL has long relied on centrifugal pumps to provide its players with anaerobic performance.
These pumps are made from stainless steel, and are usually used to pump air out of players’ lungs during training and games.
But these pumps aren’t always up to the task of providing the same amount of oxygen as the air in their players’ blood.
Last year, the league’s medical director, Dr. Jonathan Eisenberg, said the pump was “not optimal,” as the amount of blood coming into the lungs from the player’s body was insufficient to help it pump out enough oxygen.
The league decided to address the issue by revamping its centrifugal-pump-only policy.
The policy, announced this year, requires all NFL teams to use a centrifugal ink pump for training and game operations.
The goal of the policy is to provide athletes with a much higher level of oxygen during training than what they would have with an air-powered pump.
The idea is to make it easier for athletes to breathe more efficiently during games.
The rule change is a logical step for the NFL to take after several years of players being prescribed antibiotics to help them breathe better.
“There are a lot of things that could go wrong with a centrifuge-only practice, and with a player getting in the habit of using a centrifugic pump,” said Dr. Michael Gorman, a sports medicine physician at Cleveland Clinic who has worked in the field of pulmonary medicine.
“But in the context of the game and in this day and age, we should take this opportunity to provide the players with more oxygen and reduce the risk of injury.”
The policy is the first step in an effort to ensure that the players can breathe more naturally during training, according to Eisenberg.
This is an area where the NFL is currently trying to work on a new pump design that would provide the same levels of oxygen to players during training.
The new policy requires the league to develop a test for players using the new pump that will be available for them to test during games, Eisenberg said.
The tests would also include the amount and the oxygen content of the water used to create the pump.
If the test shows that the water is high in oxygen, the team will be able to increase the amount the player can breathe, Eisenburg said.
If there is no change in oxygen content during training or games, the pump will not be able go back into service.
The change in the policy, Eisenbomberg said, is to ensure the athletes are breathing more naturally.
“The more oxygen we give them, the more energy they can give to their bodies during training,” Eisenberg told the New York Times.
“We want them to be as efficient as possible during the game.
And if we don’t have that, then we’ll lose that advantage that we’re giving them.”
The change comes after several players have gotten sick with a rare bacterial infection.
These players have been given antibiotics to fight the infection, but have continued to take the medications for weeks.
That has prompted some players to question the effectiveness of using the pump, according the Times.
It’s unclear if any of the players have died as a result of the infection.
The NFLPA has not yet responded to The Verge’s request for comment about the new policy.
