Abstract
Aim: The effect of creatine (Cr) supplementation on exercise induced-lactate is still debatable. Thus, the aim of this study was to examine the effect of creatine supplementation on blood lactate levels after an exhaustive aerobic exercise.
Method: Twenty healthy young men (age: 22.4±0.8 years; weight: 71.8±8.5 kg; body mass index (BMI): 23.5±2.5 kg/m2; maximum oxygen uptake: 37.7±7.2 ml.kg-1.min-1; mean±SD) were randomly assigned to either a creatine (20 g Cr for 7 days) or a placebo group (same dosage of a glucose polymer) using a double-blind research design. After a week of supplementation, the subjects underwent an exhaustive aerobic exercise. Blood samples were taken before the exercise and immediately, 10 and 20 minute after the exercise.
Results: The results showed that body weight, BMI, lean body mass and creatine levels were increased significantly after supplementation in the creatine group (P
