I was watching a late night TV program last night, "The Creation Series" by Kent Hovind, and part of the program was about the great benefits of increased oxygen levels. According to this program, using a hyperbaric chamber (it's sort of like a diving bell, increasing the oxygen pressure and content) can cut the healing time for injuries in half, and is even showing great results in treating several illnesses. That sounds like it could be a great benefit to NFL players, even those without injuries to recover more quickly just from the normal bumps and bruses of a game.
This isn't a new program (it didn't have a date), so it's not new science, because one of the teams listed as using it were the NBA Grizzles, before they moved to Memphis. They also said that the NFL's Cowboys, 49ers, and Jets use it, and that Dolphins MLB (at that time) Zach Thomas used it as well. I'm sure some of you know a lot more about this than the little this program said about it, so tell use what you think.
Just looking at it, a hyperbaric chamber must be expensive, but they said they even make hyperbaric sleeping bags. However, the cost might be worth it, if it increases a players performance, and healing time from injuries.
They sited an example from Japan in 1985, using a tomato plant (plants take in CO2, and gives off oxygen), where they doubled the CO2 levels, so in a way it reverse mimics the effect of increased oxygen and pressure for humans. According to the TV show, the single cherry tomato plant in the experiment grew 40 feet tall, and produced around 10,000 cherry tomatos, the size of baseballs.
Like I said, I don't know anything about this except for this program, but it sounds very interesting, so let me know what you think.
