Current investigations of phosphate supplementation have focused on the physiological and performance-related outcomes of laboratory protocols including graded exercise tests to exhaustion, the 30-s Wingate test, 6 × 20 m (~3– 4 s) repeat sprint efforts, and TT situations ranging in duration from 3–60 min. Overall, there is equivocal evidence of performance enhancement from phosphate supplementation.¹

Proposed benefits include:

1. Increased aerobic capacity.
2. Increased peak power output.
3. Increased anaerobic threshold.
4. Improved myocardial and cardiovascular responses to exercise.
