“…This requires a 24 h collection of urine and is an impractical test for mass screening of athletes. Due to the challenges of assessing Mg status and the limited studies performed on athletes, the prevalence of Mg deficiency in athletes, and indeed the appropriate range for athletes are both uncertain [37].…”

Magnesium plays a critical role in athlete health and performance. It is involved in numerous physiological mechanisms that support energy production, immune function, pain modulation, muscle function and bone health. Athletes may be susceptible to magnesium deficiency due to an increased utilisation during exercise. ObjectiveThis study reports on the magnesium status of 192 Olympic and Paralympic athletes over the course of eight years. MethodsAthletes on the British Athletics world class performance plan undertook blood testing for Red Cell Magnesium status. Their history of tendon pain, muscle and bone injury, ethnicity, sporting event and gender were also recorded. 510 samples from 192 athletes were included in the study. ResultsOn at least one blood test during the study time, 22% of athletes were identified as clinically deficient (<1.19 mmol/L). The average red cell magnesium concentration was 1.34 nmol/L. Magnesium was significantly lower in female athletes and those with Black or Mixed-Race ethnicity and was higher in Throws athletes and Paralympians with Cerebral Palsy. Athletes with a history of achilles or patella tendon pain had significantly lower magnesium levels than average. ConclusionsThis study highlights the importance of investigating magnesium within this population to identify deficiency and mitigate against potential performance reduction or increased injury risk. Several areas for future work are identified to explore the relationship between magnesium and gender, ethnicity and tendon pain and muscle injury in athletes. Furthermore, new guidelines for magnesium status within athletics populations are proposed.

Background: The present study aimed to determine changes occurring in the erythrocyte concentrations of Iron (Fe), Magnesium (Mg) and Phosphorous (P) of subjects with different levels of physical training living in the same area of Extremadura (Spain). Methods: Thirty sedentary subjects (24.34 ± 3.02 years) without sports practice and a less active lifestyle, formed the control group (CG); 24 non-professional subjects (23.53 ± 1.85 years), who perform between 4 and 6 h/week of moderate sports practice without any performance objective and without following systematic training formed the group of subjects with a moderate level of training (MTG), and 22 professional cyclists (23.29 ± 2.73 years) at the beginning of their sports season, who performed more than 20 h/week of training, formed the high-level training group (HTG). Erythrocyte samples from all subjects were collected and frozen at − 80°C until analysis. Erythrocyte analysis of Fe, Mg and P was performed by inductively coupled plasma mass spectrometry (ICP-MS). All results are expressed in μg/g Hb. Results: The results showed that there were statistically significant lower concentrations of erythrocyte Fe, Mg and P in MTG and HTG than CG. All parameters (Fe, Mg and P concentrations in erythrocytes) correlated inversely with physical training. Conclusions: Physical exercise produces a decrease in erythrocyte concentrations of Fe, Mg and P. This situation could cause alterations in the performance of athletes given the importance of these elements. For this reason, we recommend an erythrocyte control at the beginning, and during the training period, to avoid harmful deficits.
