Does sodium citrate improve sprint times, peak power, minimum power, and mean power during repeated sprints?\n2. Does sodium citrate lower fatigue index (the drop in power across sprints) during repeated sprint exercise?\n3. Does sodium citrate change blood bicarbonate, pH, and lactate levels before and after exercise?\n4.
