Abstract

Background : Iron known to have important role in energy metabolism, because iron work in oxygen transport which needed in carbohydrate, protein, and fat metabolism to produce energy (ATP). ATP is important for muscle contraction. When oxygen supply to the tissue was not enough, anaerobic metabolism occurs producing lactic acid. Lactic acid accumulation will lead to muscle fatigue. Because of that, wingate test will be peformed to evaluate muscle fatigue which occurs in anaerobic phase by evaluate anaerobic fatigue (AF) parameter and ergometer bicycle test in aerob phase by evaluating the comparison between VO2Max mean value. Methods : This was experimental study with post test only controlled group design .The subjects of this study were 48 male students of medical faculty Diponegoro university (19-21 years old range )that fulfilled the exclution and inclution criterias. The subjects were divided into 2 groups, control (without treatment) and treatment group. Treatment group was given iron supplementation a week before the test.. Anaerobic phase of muscle fatigue was measured with Wingate test, aerobic phase was measured with Ergocycle test. Results: Measurement with Wingate test, proportion of fatigue(in %) based on AF value on treatment group was smaller than the control group. Chi square test result in p=0,119, so that it can be concluded as unsignificant. Measurement with ergocycle test result in VO2Max mean difference between treatment and control group, where the mean of control group was smaller than the treatment group. T-independent test result in p=0,061, so it can be concluded that the difference was not significant. Conclusion: Administration iron supplementation one week before exercise doesn’t affect muscle fatigue neither anaerobic (AF) nor aerobic phase (VO2max). Keywords : Iron suplementation, Anaerobic fatigue(AF), VO2max
