Minerals and sports


Minerals are essential to the body. Mineral intake is a factor of good health. A balanced diet usually cater for the athlete's needs, however, certain adjustments may be necessary in specific circumstances, such as intensive sports, specific conditions, or insufficient sunlight...

Overview of minerals

The quantities of minerals in the body differ widely: almost 1kg of calcium and phosphorus, only a few grams of iron and zinc and less than 1mg of chromium and cobalt. All in all, the mineral elements account for approximately 4% of the body weight, but they are involved in a wide range of functions: lipids, carbohydrates and proteins metabolism, formation of the skeleton, proper function of the nervous system, muscle contraction, oxygen transportation, etc.

For example, the thyroid hormone cannot be produced without iodine, hemoglobin cannot be produced without iron, and there's no muscle contraction without calcium, potassium and magnesium.

Remember: Minerals do not provide energy and work at very low quantities.

Mineral intake

Daily intakes of mineral elements help compensate the losses suffered by the body. A balanced and varied diet guarantees sufficient intakes.

Mineral elements are water soluble, resulting in a more or less important loss depending on the food cooking methods.

Minerals and sports

Endurance athletes have increased needs in many minerals. The deficiency of one mineral or another will alter their performances, health and well-being.

Although they work at low concentration, the needs in minerals will depend on the level of exercise.

Dietary adjustments sometimes consist of eating more of certain foods to avoid any risk of deficiency, and help reach an optimal state of well-being and performance, without using supplements.
