Effect of Magnesium Supplementation on Serum Magnesium and Lactic Acid in Athletes

Abstract

The aim of this study was to investigate the effects of magnesium supplementation on serum magnesium and lactic acid levels in boxers. The study included 20 male athletes (experimental group: n=10; control group: n=10) with a mean age of 22.32 ± 4.21 years, operating in boxing clubs in Sakarya province. In the study, 250 mg magnesium citrate supplementation was administered daily to the experimental group during an 8-week strength training program. Body composition, serum magnesium level and blood lactate level measurements were performed on all participants as pre-test and post-test. The data were analyzed using two-way repeated measures analysis of variance (2x2 ANOVA) in the SPSS 26 program. According to the results of the study, a 2.79% increase in serum magnesium levels was observed in the experimental group, while a 2.74% decrease was observed in the control group. In addition, a 34.53% decrease in blood lactate levels was recorded in the experimental group, while a 49.31% increase was recorded in the control group. Group-time interaction was found to be statistically significant in terms of serum magnesium and blood lactate levels (p<0.05). These findings indicate that magnesium supplementation can reduce fatigue and increase athletic performance by maintaining biochemical balance during the training process.

Sporcularda Magnezyum Takviyesinin Serum Magnezyum ve Laktik Asit Üzerine Etkisi

Abstract

Bu araştırmanın amacı, magnezyum takviyesinin boksörlerde serum magnezyum ve laktik asit düzeylerine etkisini incelemektir. Çalışmaya, Sakarya ilindeki boks kulüplerinde faaliyet gösteren, yaş ortalaması 22.32 ± 4.21 yıl olan 20 erkek sporcu (deney grubu: n=10; kontrol grubu: n=10) katılmıştır. Araştırmada, 8 haftalık kuvvet antrenman programı süresince deney grubuna günlük 250 mg magnezyum sitrat takviyesi uygulanmıştır. Tüm katılımcılara ön test ve son test olacak şekilde vücut kompozisyonu, serum magnezyum düzeyi ve kan laktat seviyesi ölçümleri yapılmıştır. Veriler SPSS 26 programında iki yönlü tekrarlı ölçümler varyans analizi (2x2 ANOVA) ile analiz edilmiştir. Araştırma sonuçlarına göre, deney grubunda serum magnezyum düzeylerinde %2.79 oranında artış, kontrol grubunda ise %2.74 oranında azalma gözlenmiştir. Ayrıca, deney grubunun kan laktat düzeylerinde %34.53 oranında düşüş, kontrol grubunda ise %49.31 oranında artış kaydedilmiştir. Serum magnezyum ve kan laktat düzeyleri bakımından grup-zaman etkileşimi istatistiksel olarak anlamlı bulunmuştur (p<0.05). Bu bulgular, magnezyum takviyesinin antrenman sürecinde biyokimyasal dengeyi koruyarak yorgunluğu azaltabileceğini ve sportif performansı artırabileceğini göstermektedir.
