Effects of acute creatine supplementation on iron homeostasis and uric acid-based antioxidant capacity of plasma after wingate test.

Regarding performance in the Wingate test (Table 2 ), neither anaerobic capacity (AnC; p = 0.1275) nor total workload (TotalWL; p = 0.1040) were significantly altered by creatine supplementation, whereas maximum anaerobic power was significantly increased by 10.5 % (AnP peak ; p = 0.0029) and the fatigue index showed a strong trend for anaerobic effort reduction upon creatine supplementation (p = 0.0890).
