Don’t overlook the importance of Magnesium in your diet while training.
“In many nerve cells, magnesium serves as a chemical gate blocker – as long as there is enough magnesium around, calcium can’t rush into the nerve cell and activate the nerve. This gate blocking by magnesium helps keep the nerve relaxed. If our diet provides us with too little magnesium, this gate blocking can fail and the nerve cell can become over-activated. When some nerve cells are over-activated, they can send too many messages to the muscles and cause the muscles to over-contract. This chain of events helps explain how magnesium deficiency can trigger muscle tension, , , muscle cramps, and muscle fatigue.” – World’s Healthiest Foods
Sweat loss can inhibit important functions of magnesium and other electrolytes. And as cited above, low magnesium levels can cause muscle fatigue. Make sure your electrolyte refuel products include some sodium, potassium and magnesium. Accelerade is known to have the most out of all sports drinks.
