KINE 150 Lecture : Hydration During Exercise
Document Summary
During exercise, muscles produce tremendous amounts of heat. > consequently, loss of water from the body is necessary to prevent over-heating: typical sweat loss during running under average environmental conditions is about 1. 5 quarts of water per hour. This is equivalent to six 8-oz. cups of water per hour to replace the water loss. During exercise: to anticipate your water needs before exercise, plan ahead and drink about two cups of water or other fluid two hours before you plan to exercise. > when you do this, your stomach works like a built-in, time- release water bottle that gradually releases fluid into small intestine where it can be absorbed into the blood and delivered throughout the body where it is needed. It can be a challenge to determine how much fluid you need during exercise. > the longer the bout of exercise, the more important it is to take care of hydration.
