Abstract

Background: In the world of sports, oxygenated drinking water is believed to have ability in increasing athlete's physical stamina and oxygen saturation transferred by blood. Elevation of physical stamina and oxygen saturation occur when body's cardiorespiratory endurance is in a good condition. Ergocycle test is a method which can be used to determine body's cardiorespiratory endurance indirectly. Objective: The objective of this research is to find out the effect of administration of oxygenated water on cardiorespiration endurance (VO2Max). Method: This study used a parallel group post-test only design. Research subject involved are men aged 19-21 year old and registered as student in FK UNDIP (n=40). Research subject randomly divided into 2 groups: oxygenated water group (n=20) and mineral water group (n=20). VO2Max level was measured by Ergocycle test. Data were analyzed using SPSS for Windows v.15.0 Results: The average of maximal oxygen uptake (VO2Max) in man aged 19-21 year old administered with oxygenated water is 45.5 ml/kgBW/min while the average of maximal oxygen uptake (VO2Max) in man aged 19-21 year old administered with mineral water is 49.0 ml/kgBW/min. Statistic test results show that there is no significant difference on VO2Max between two groups (p=0.5). Conclusion: There is no significant difference in VO2max level between group administered with oxygenated water compared with group administered with mineral water only. Keywords: Oxygenated water, maximal oxygen uptake (VO2Max), Ergocycle test.
