Abstract
Objective:The purpose of this study is to determine the effect of magnesium supplements on the muscular strength of active men.Materials and Methods:Samples were matched into two groups. Magnesium supplements (containing 47 mg of calcium and 250 mg of magnesium oxide produced by al-Hawi Company) were given to the experimental group and the placebo that was completely similar to the supplements for thecontrol group. The tablets are given to every other subject individually and they performed strength training. Supplements were ingested before strength training in the gym and the supplements were consumed with a glass of water. The statistical population of the study included male bodybuilders’ athletes who are regularly excising three days a week in Shahre Kord sports clubs. 40 subjects were selected from people who were interested to participate in the research. After selecting the samples, they are randomly divided into two groups A and B (double-blind method). The strength of the athletes was measured by the CPR machine based on the 1-RM and their resistance by more repetition ofbench press with a standard device using 1-RM by 0.5 Kg in the gym. Results:The results of Wilks' lambda test showed that there is a significant difference between the experimental and control groups in one of the measurements related to arms muscle strength and chest muscle strength, while there is no a significant difference between the two groups in measurements related to muscle strength and resistance of the upper body, which means that magnesium supplementation for 8 weeks has had a significant effect on the strength of the hands and chest muscles of the bodybuilders ‘athlete.Conclusion:Magnesium supplementation can affect the strength of upper body’s muscles of men.
