Calcium is responsible for heart muscle contractions and regulates nerve function.
Calcium can prolong time to exhaustion and increase maximum power.
Dr. Michael Colgan states, " …in order for life to continue, the level of calcium outside your bones has to be maintained within very narrow limits. If your calcium intake is inadequate for even a day, then your body cannibalizes it’s own skeleton to make up the deficit… Over a span of 20 years, numerous studies have found that athletes in a wide variety of sports, have deficient intakes of calcium."
