摘要

目的:研究补充镁(Mg)对运动不足时肌肉Mg含量和Mg损失的影响;减少运动)。方法:对40名身体健康的男性志愿者进行预实验期30天和实验期364天的研究。受试者平均分为4组:未补充对照组(UCS)、未补充实验组(UES)、补充对照组(SCS)和补充实验组(SES)。SCS组和SES组每天每公斤体重补充3.0 mmol氯化镁。结果:与实验前及对照组(SCS组和UCS组)相比,SES组和UES组肌肉Mg含量降低(p< 0.05),血浆Mg浓度降低(p< 0.05),尿液和粪便中Mg的损失增加(p< 0.05)。SES组肌肉Mg含量下降幅度大于UES组(p< 0.05),血浆Mg浓度、尿、粪中Mg损失增加幅度大于UES组(p< 0.05)。结论:缺镁饮食不会降低肌肉中Mg的含量,肌肉中Mg含量的升高不会增加身体中Mg的损失,而是由于身体无法利用Mg所致;这是因为除非镁沉积减少,否则补充镁不会降低肌肉中的镁含量,而镁损失不会随着肌肉缺镁而增加。

Magnesium Supplementation Effect On Muscle Magnesium Content And Magnesium Loss In Humans During Hypokinesia
Objective: To study the impact of magnesium (Mg) supplementation on muscle Mg content and muscle Mg loss during hypokinesia (HK; diminished movement). Methods: This study was conducted on 40 physically healthy male volunteers during a pre-experimental period of 30 days and an experimental period of 364 days. Subjects were equally divided into four groups: unsupplemented control subjects (UCS), unsupplemented experimental subjects (UES), supplemented control subjects (SCS), and supplemented experimental subjects (SES). A daily supplementation of 3.0 mmol of magnesium-chloride per kg body weight was given to the subjects in the SCS and SES groups. Results: The muscle Mg content decreased (p<.05) and plasma Mg concentration, and Mg loss in urine and feces increased (p<.05) in the SES and UES groups compared to their pre-experimental levels and the values in their respective control groups (SCS and UCS).The muscle Mg content decreased (p<.05) more, and plasma Mg concentration, and Mg loss in urine and feces increased more (p<.05) in the SES group than in the UES group. Conclusion: It is concluded that muscle Mg content is not decreased by the Mg deficient diet and bodily Mg loss is not increased by the higher muscle Mg content but due to the inability of the body to use Mg; this is because muscle Mg level cannot reduce with Mg supplements and Mg loss cannot increase with muscle Mg deficiency unless Mg deposition decreases.
