Skeletal muscle total-creatine (TCr) content during 6 days of creatine + carbohydrate (Creatine, n = 7) or glycine + carbohydrate (Placebo, n = 7) supplementation following glycogen-depleting exercise in man. Results are expressed as means ± SEM with units of mmol kg⁻¹ dry muscle. Different from the pre-supplementation time point (post-exercise, time 0) within the same treatment group (^† P < 0.05, ^†† P < 0.01); different from placebo at the corresponding time point (*P < 0.05, **P < 0.01)
