? Water ?

[sysopt]

This very famous trainer (trains pro football players for fun) was telling me that water is absolutely essential for muscle recovery, he was saying it flushes all the crap out. Can someone please tell me the details about water, it's function, and why it's so important?

Second only to oxygen, water is needed the most out of all the 40+ nutrients used by all bodies. It is needed to maintain homeostasis, it is the most abundant solvent or medium in the human body, it's important in regulating cell volume, nutrient transport, waste removal, and body temperature. It's distributed both in intra- and intercellular compartments and accounts for up to 80% of our body weight at birth and up to 70% of our adult body weight. Our bodies can't store excess water for future times of need, so daily intakes are essential for almost all body functions, including digestion, absorption, circulation, excretion, transporting nutrients, building tissue, and maintaining body temperature.

It also is well-established that fluid needs vary depending on a variety of factors, such as climate, age, exercise level, and body weight. The average adult loses about 10 cups of water on a typical day. Most people need roughly eight to 12 cups of fluid a day. More specifically, the International Sports Medicine Institute in West Los Angeles suggests a person drink 2/3 ounces per pound of body weight each day if they are active (12+ glasses for an active 150-pound person) and 1/2 ounces per pound if they are not active (9+ glasses of water for a 150-pound sedentary person).
