Is it beneficial to take oxygen before running 800 meters? Can you run fast?
This has a certain effect! Increasing the oxygen storage capacity of body muscles is objectively beneficial to explosive force and slowing down the time of muscle hypoxia! Have you seen a record just released by Guinness World Records-the video of diving 200 meters in one breath? He took a few minutes of pure oxygen to start! But the key to victory is strength! Persistence is the key!
