The effect of magnesium supplementation on lactate levels of sportsmen and sedanter

Abstract

This study was performed to assess how magnesium supplementation affects plasma lactate levels at rest and exhaustion in sportsmen and sedentary. Research was performed on 30 healthy subjects varying between 18-22 years of age for a four-week period. Subjects were separated into 3 groups: Group 1; sedentary taking magnesium supplementation only (10 mg/kg/day) (Mg + S), Group 2; subjects magnesium supplemented + training 90-120 min 5 days a week (Mg + Training), Group 3; training 90-120 min 5 days a week. Lactate levels of the groups were measured 4 times; at rest and exhaustion in the beginning of the research and after the end of the research. At the end of the research, exhaustion measurements both before and after supplement were found significantly higher than rest measurements in terms of lactate levels (p < 0.05). An important decrease was determined in the lactate levels of the 1st and 2nd groups when compared to their first measurements (p < 0.05). The results of this research indicate that lactate increases with exhaustion. However, magnesium supplement may positively affect performance of sportsmen by decreasing their lactate levels.

The Association Between Admission Magnesium Concentrations and Lactic Acidosis in Critical Illness

“…14 In adjusted analyses, including measurement of comorbidities, illness severity, blood pressure, and renal function, hypomagnesemia remained a significant predictor of lactic acidosis. Although lactic acidosis in critical illness is often assumed to reflect tissue hypoperfusion in response to a low-flow state and used to direct fluid resuscitation strategies, our analyses suggest that magnesium concentrations are an additional independent predictor.…”

“…12 In the absence of magnesium, disrupted oxidative phosphorylation shifts toward anaerobic metabolism, resulting in lactic acid production. Magnesium infusion attenuates lactate production during surgical procedures 13 and intense physical exercise, 14 but little information exists on the association of magnesium and lactate concentrations in the critically ill patients.…”

Vitamins and Minerals for Energy, Fatigue and Cognition: A Narrative Review of the Biochemical and Clinical Evidence

“…Data from animal studies suggest that magnesium might improve exercise performance via enhancing glucose availability in the brain, muscle and blood, and reducing/delaying lactate accumulation in muscles, which may delay exhaustion [115]. The positive impact on lactate has been observed in a controlled clinical study where magnesium supplementation (10 mg/kg body weight/day) for 4 weeks attenuated the exercise-induced increase in plasma lactate levels of 30 young Tae-Kwan-do sportsmen [139].…”

Can Magnesium Enhance Exercise Performance?

“…Physiological indices have been used as the proxy measures of exercise performance [ 28 , 29 , 36 , 37 , 38 , 39 ]. For example, in one randomized controlled trial [ 40 ], the researchers randomly divided 30 healthy individuals (aged 18–22 years) into three groups: (1) Mg supplementation group; (2) Mg supplementation + Tae-Kwan-Do training group; and (3) Tae-Kwan-Do training group. After a 4-week intervention, the results indicated that Mg supplementation improved exercise performance, measured by a 20 m shuttle run test, through decreasing the accumulation of lactate, which was consistent with the findings from animal studies [ 18 , 26 , 27 , 32 , 33 ].…”
