Abstract

 
The aim of this study was to investigate the effect of magnesium sulfate supplementation on fatigue threshold electromyography (EMGFT), lactate and time to exhaustion (TTE) following a session of aerobic exercise (exhaustive treadmill running) in sedentary collegiate men. For this purpose, 16 sedentary male students (mean age: 25.25 ± 1.18 years, height: 176.18 ± 4.75 cm, weight: 79.51 ± 25.65 kg) were randomly divided into supplementary (n=8) and placebo (n=8) groups. Blood samples were collected in four phases: before and immediately after Bruce test in pretest and posttest. Data were analyzed by repeated measures test, covariance analysis and independent and dependent t tests at P=0.05. The results showed that TTE increased (5.44%) in magnesium sulfate group after the supplementation (P<0.05). Also, magnesium sulfate supplementation increased the occurrence of EMGFT (140%) (P<0.05). But the lactate changes were not significant in both groups (P>0.05). The results of this study indicated that the supplementation of magnesium sulfate lowered the slope of muscle EMGFT activity following a session of exhaustive treadmill running.
