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.

Baseline and post-intervention assessments included countermovement jump (CMJ), countermovement jump with arm swing (CMJWH), zig-zag agility, and shooting speed, with post-tests conducted after a 4-minute recovery period. Perceptual responses, including ratings of perceived exertion (RPE), perceived discomfort (RPD), and fatigue (VAS), were recorded immediately after each protocol.
