During monday night football last night the announcers were talking about a special type of mouth piece that the New Orleans Saints use that somehow improves flexibility, power, and oxygen flow. Test show that vertical leap, power, and overall performance are better when wearing one of these things. If power is increased while wearing this, wouldn't it be useful to wear one of these things for swimming? I don't want to get in a "tech" argument but I thought this mouthpiece is pretty cool.
