Impact of Mar’ke Bilar Healthy Drink on Blood Levels of Malondialdehyde, Superoxide Dismutase, and Hemoglobin in Soccer Athletes at PPLP North Sumatra

Abstract

Background: High-intensity soccer activities due to overtraining can cause the emergence of reactive oxygen species (ROS), resulting in an imbalance of free radicals in the form of malondialdehyde (MDA) and endogenous antioxidants in the form of superoxide dismutase (SOD). As a result, it can interfere with the formation of hemoglobin (Hb) needed by an athlete to take in oxygen (VO2max). Objectives: This study was designed to determine the effect of giving a healthy drink Mar’ke Bilar on MDA, SOD, and Hb levels in soccer athletes at PPLP North Sumatra, Indonesia. Methods: This type of research is quasi-experimental with a one-group pre- and post-test design. The population and research samples amounted to 33 soccer athletes at PPLP North Sumatra. The administration of Mar’ke Bilar as much as 200 ml was carried out for 14 days, and then MDA, SOD, and Hb levels were measured before and after. A normality test was conducted with the Kolmogorov-Smirnov test, followed by a different test using a paired t-test. Results: Malondialdehyde levels decreased from 17.5 to 10.9 µmol/L. There was an increase in SOD from 45.945 to 53.256 pg/mL. However, the results of Hb also showed an increase from 14.3 to 15.1 gr/dL. There was a significant effect on levels of MDA (P = 0.001), SOD (P = 0.001), and Hb (P = 0.002). Conclusions: Mar’ke Bilar healthy drink consumption has an effect on reduced MDA levels and increased SOD and Hb.
