The Consumption of Yellow Watermelon-plantain Juice before Anaerobic Exercise Improves Blood Glucose and Suppresses Oxidative Stress Formation in Rats

Abstract

Food supplementation prior to exercise could supply glucose for energy booster and enhanced performance. Food supplements with potent antioxidant activity could also help alleviate oxidative stress formation during exercise. This study aiming to investigate yellow watermelon-plantain juice administration prior to anaerobic exercise on blood glucose level and its protective effect on markers of oxidative stress formation that is malondialdehyde (mda) serum level. Thirty-five male Sprague Dawley rats were divided into five different groups in which received different treatments. Anaerobic exercise in this study was set as swimming test for three minutes. Blood glucose level were examined as baseline, thirty minutes after juice supplementation, and after exercise test. P2 groups has the highest blood glucose level before and after exercise (111.86 mg/dl and 100.52 mg/dl, respectively). Mda level after exercise differ significantly between groups (p < 0.05) with negative control group has the highest level of Mda (7.68 nmol/ml) and P2 has the lowest level among treatment groups (1.8 nmol/ml). It can be concluded that yellow watermelon-plantain juice supplementation prior to anaerobic exercise is an effective source of energy due to its rapid glucose availability in the serum. Antioxidant content in yellow watermelon-plantain juice could also suppressed malondialdehyde serum level after exercise
