Tourville, T. W., Brennan, K. M., & Connolly, D. A. (2001). The effects of sodium phosphate supplementation on anaerobic power in trained male athletes. Medicine and Science in Sports and Exercise, 33(5), Supplement abstract 929.

This investigation tested whether sodium phosphate supplementation would increase power in athletes. Trained male cyclists (N = 12) performed a pre-supplementation and post-treatment 30-s Wingate Test. Ss were randomly assigned to a sodium phosphate supplementation or placebo group. Supplementation was 4 x 1000 mg/d for four days.

There were no significant differences between pre- and post-test measures for either group.

Implication. Sodium phosphate supplementation in trained male cyclists is not an ergogenic aid for anaerobic work.
