Magnesium and sport

Elevated magnesium requirement during sports

More than 300 enzymes in the human body need magnesium as a co-factor and magnesium plays an important role in all intracellular metabolic processes that are involved in the synthesis or metabolism of energy-rich compounds (e.g. glucose). The enzymes involved in glucose metabolism require magnesium for their activation. No energy can be produced without magnesium. The formation of lactate (anaerobic glucose metabolism) in the muscle, when the oxygen supply is insufficient, places limitations on physical performance. The lactate must therefore be eliminated from the body as rapidly as possible, a process which also requires magnesium. Thus, an adequate magnesium supply is of particular importance for sport. Magnesium requirements are substantially increased by the raised metabolism during sport.

Magnesium and muscle function

The high physical strain that occurs during sport favours magnesium consumption and losses that are primarily caused by a raised metabolism and increased perspiration. Fluid losses are substantial (up to 2 litres per hour), in particular when the surrounding temperatures and humidity are high. Another cause for a magnesium deficiency is elevated magnesium use attributable to rapid metabolism or increased secretion via the kidney.

Therefore endurance athletes, in particular, more frequently suffer from magnesium deficiency than people who do not take part in endurance sports. Hence  athletes crucially need to compensate their magnesium losses during the recovery phase, so that a deficiency in magnesium can be avoided befor physical activity begins. A magnesium deficiency can rapidly occur becuase of an inadequate magnesium supply, which then manifests itself through neuromuscular hyperactivity. In such cases, muscle spasms and cramps will occur more frequently and susceptibility to muscular tension, torn muscle fibres and muscle strain is increased.

Sportsmen need more magnesium – the intake of additional magnesium citrate can compensate the increased demand for magnesium

Magnesium sustains performance

Increased muscular activity and perspiration causes the body to consume or lose magnesium during sport. To sustain muscle function and performance in the long-term, sportsmen need quickly to compensate any magnesium and fluid deficiencies that have developed, e.g. with Magnesium-Diasporal® 400 EXTRA, granules for oral solution.

Magnesium should be administered regularly during the recovery phase after any sporting activity in order to sustain physical performance levels over the longterm. Performance might be adversely affected if high doses are taken immediately prior to sport because of to the slight laxative effect of magnesium.
