Mg supplementation can maximize energy stores for exercise, decrease indicators of inflammation, and increase the rate of lactate clearance. While these functions of Mg can benefit exercise capabilities, research is lacking on their effects on specific performance parameters. The purpose of this study was to determine if Mg supplementation would increase performance parameters in NCAA Division-I football players. Eighty-one participants were separated into position groups and randomly assigned to receive a daily placebo, low dose of Mg (100 mg), or high dose of Mg (200 mg). Participants completed a pre- and post-test for performance parameters that included 1RM clean, 1RM squat, 1RM bench press, vertical jump, and broad jump. Every parameter except vertical jump and broad jump had a mean increase from pre-test to post-test. In the control group, significant differences (=0.05) were noted for the 1RM clean (8.148 ± 5.238), 1RM squat (12.370 ± 8.876), 1RM bench (9.222 ± 4.854), P4P (.840 ± .118), and total pounds (29.741 ± 16.519). In the low dose Mg group, significant differences were noted for the IRM clean (8.111 ± 5.228), 1RM squat (11.889 ± 8.894), 1RM bench (7.115 ± 4.572), and total pounds (26.852 ± 16.703). In the high dose Mg group, significant differences were noted for the 1RM clean (8.593 ± 5.235), 1RM squat (11.741 ± 7.679), 1RM bench (7.000 ± 9.695), vertical jump (.841 ± 1.861), P4P (.093 ± .113), and total pounds (27.071 ± 14.697). These differences among treatment groups are likely attributed to the effect of training. A one-way ANOVA (=0.05) was used to determine statistical differences between and within treatment groups, but no significant differences were noted. In conclusion, supplemented Mg had no effect on the performance parameters in this study.
