Judul: The effect of oxygenated water on exercise performance, CD4, CD8, CD56, IL-6 and malonaldehyde content.
Abstrak: Oxygen is an essential substance for human life, as well as water and food. Oxygen is available in the air and can be enjoyed for free. However, many people have problems in obtaining sufficient oxygen. Exercise requires more oxygen and cannot be fully obtained by respiration. Limited supply of oxygen result energy will not be sufficient to exercise in the long term and the buildup of lactic acid in the muscles will cause weariness and further degrade the performance and achievements of athlete. Oxygen is needed by normal cells in the body, including immune cells. Within the immune system, there are several kind of cells that maintain the body's defenses: CD4, CD8, CD56 and IL-56. CD4 protein is a marker protein of Th cells (T helper), CD8 protein is a protein marker of Tc cells (T cytotoxyc), CD 56 protein is a protein marker of Natural Killer cells (NK), and IL-6 is a cytokine produced by muscle cells. In response to muscle contraction from activity or exercise. The oxygen requirements promote scientists and industry to create an alternative oxygen supply in the body through drinking water. This study aimed to determine the effect of oxygenated water consumption to lactate levels, energy expenditure, CD4 , CD8 , CD56 and IL-6 protein content. In addition, to study the consumer safety based on malonaldehyde levels. The study was conducted by recruiting subjects from IPB student who likes to exercise. Selected subject population numbered 17 IPB students who active exercise, ie exercise regularly at least 20-30 minutes per day, three times a week or the equivalent. The sports are futsal (47.06%), badminton (29.41%), table tennis (5.88%), cycling (5.88%), martial arts (5.88%) and jogging (5.88%). Respondents consisted of men between the ages of 20-27 years, S1 students (76.47%) and S2 students (23:53%). Before the intervention, medical check prior to each respondent. Respondents were selected are students who are otherwise healthy based on the results of medical checked by a physician at the Clinic Dr. Katili, Dramaga. Furthermore socialization. In socialization explanation is given as oxygenated water, benefits¸ correct way of consumption, stage of research to be conducted and signing the informed consent (letter of agreement) for respondents who are willing to join the study. In short-term, twelve male student volunteers drank 385 ml oxygenated water (50, 80 and 130 ppm) or mineral water, 15 minutes before treadmill and after treadmill (10 Kmh). The lactic acid concentration was measured before and after treadmill, and 5 minutes after the reconsumption of the oxygenated water. In long-term, seventeen male student volunteers drank oxygenated water twice a day (100 ppm) for 21 days. The blood plasma and lymphocyte sampled before and after intervention were analyzed according to the parameters. Consumption of oxygenated water can lower lactate levels after exercise more than mineral water, and generate higher energy expenditure than mineral water in the short term, but statistic test results show that there is no significant difference between two groups (p>0.5). In the long-term intervention for 21 days showed that oxygenated water can increased levels of CD4 and CD8 content, statistic test
