Figure 2. The effects of creatine (Cr) supplementation on endurance swimming time performance in rats. No Cr supplementation (CON, n = 15), Incomplete food intake (INCO, n = 15), Cr supplementation 1 g·kg-1·day-1 (CREAT-I, n = 15), and Cr supplementation 2 g·kg-1·day-1 (CREAT-II, n = 15). All data are reported as means (SD). *Significantly different from CON values (p < 0.01).
