Is there a balance of how much water should be taken in? The specific scenario I am referring to, would be sports, in my case, hockey. When I first started playing hockey I drank two 16 oz plastic water bottles during a game, now at a minimum, I have three sips of one of those same water bottles during a game. I am more conditioned and I do believe I have more endurance, which may require less water? Why - because my muscles hold more water??
I am always wondering if less, smaller, more frequent gulps of water may be more effective; but even then, during a game, I merely drink water because I brought the bottle out on the bench with me.
On the other side of the equation, I wonder if oxygen is really what I need more of. When I watch professional hockey players on national TV, I see them taking small sips and often spitting water out immediately after taking a sip. This unfortunately draws be to a perhaps an absurd conclusion - are they only looking to absorb water through their salivary glands? Is there a decrease in oxygen intake after the intake of water?
