Replenishing electrolytes after strenuous exercise is crucial, and magnesium has a particularly role in muscular health and recovery. Researchers studying marathon runners found magnesium to be the most highly depleted electrolyte in athletes, followed by potassium.
Bananas are an abundant food source of both magnesium and potassium, as well as being a conveniently portable high-energy snack – no wonder this year’s Wimbledon saw the total consumption of 2,100 kg of bananas by players. Magnesium is a vital mineral required for the mechanism of muscle relaxation to occur.
Without magnesium our muscles would remain in a permanent state of contraction, which is why this mineral is a particularly important consideration for athletes and the fitness community. The combined factors of stressors places upon the muscles and the natural loss of electrolytes during exercise, means that the replenishment of magnesium is a crucial part of effective muscle recovery.
Beyond the matter of muscular function, magnesium is a powerful anti-inflammatory mineral offering protection against illnesses such as Alzheimer’s Disease and arthritis. Magnesium is a vital mineral for general health as it assists in the body’s ability to absorb calcium into bone matter, and is crucial for nerve function. Without sufficient magnesium intake, elevated levels of calcium occur in the blood stream which can contribute to heart problems and poor bone health. A long-term magnesium deficiency can contribute to the development of osteoporosis, particularly in women.
Symptoms of Magnesium Deficiency
Mild magnesium deficiency is relatively commonly among the modern day general western population, believed to be the by-product of modern farming and food processing methods. Over 60% of the western population are believed to be deficient in the mineral, with 30% of the US and UK population consuming below the recommended daily intake of magnesium within their daily diet.
Symptoms of low-level magnesium deficiency include muscular symptoms such as cramping, muscle spasms, and prolonged muscle soreness and tension without improvement or recovery. Mild magnesium deficiency can also present symptoms of poor sleep, anxiety and an inability to relax.
The most precise method to determine a mild deficiency is generally believed to be cellular testing, as only 0.3% of the body’s magnesium is stored in the blood serum.
Magnesium and nutrition
Foods rich in magnesium include dark green leafy vegetables such as spinach, bananas, nuts and seeds, dried apricots, fish, legumes, natural yogurt and dark chocolate. Those with an existing magnesium deficiency, or those with digestive issues that impede upon correct nutrient absorption, may wish to take a high-quality oral supplement. As with all vitamin and mineral supplements, it is advised to check the appropriate dosage with a health care professional. Requested blood work can determine your existing blood serum levels of magnesium, and whether you are in need of supplementation.
As exercise leads to the natural depletion of electrolytes and trace minerals in the body, replenishing magnesium lost during exercise can aid muscle recovery and negate potential soreness and aches after an intensive work out. Sports drinks, designed to replenish electrolytes lost during exercise, contain magnesium, and certain mineral waters contain a trace amount of the mineral. Whilst nutritional sources are excellent supplies for daily maintain, there are other options which maximize muscular absorption of magnesium.
Transdermal magnesium for muscle recovery
An option which is gaining strong popularity in the sporting and fitness community, is to replenish magnesium using topical products. Transdermal products such as bath salts, lotions and sprays allow magnesium to be absorbed instantly into the skin for immediate assimilation by the muscles. This is an excellent choice, particularly for those without an existing long-term magnesium efficiency, who wish solely to aid muscle recovery after intensive sports and exercise.
Magnesium bath salts
Bathing in magnesium salts supports muscle recovery on two levels, efficiently utilizing the dual benefits of immersive heat therapy and the replenishment of depleted magnesium stores from exercise-induced electrolyte loss. This is why epsom salts are such an important bathroom and locker-room staple of many professional athletes and dancers. Epsom salts are widely accessible from pharmacies, and magnesium bath flakes are readily available online.
Magnesium recovery sprays and lotions
Increasingly some athletes have made a topical magnesium spray or lotion part of their sports kit, utilizing it for efficient assimilation into the blood stream, effectively negating the effects of muscle strain and tension after exercise. As with magnesium salt baths, this method provides immediate magnesium replenishment to the body, but with the added time-saving convenience and portability of the product.
The use of a topical magnesium product is particularly beneficial for those undergoing intensive weight training – such as bodybuilders – and those undertaking sports involving short periods of sprinting. Both activities have a particular tendency to cause shortening and bulking of the muscles, which causes heightened stress to the muscles. Replenishing magnesium can help negate soreness and tightness associated with intensive muscle stress.
Magnesium is a vital mineral and ensuring your requirements are met is necessary to optimum health. Boosting your intake of magnesium via nutritional and topical means can aid muscle recovery after exercise, negate post-exercise muscular discomfort, and therefore can potentially assist muscular recovery and boost athletic performance.
