Abstract

This study was aimed to investigate the effect of mangosteen rind on the glycogen recovery of the muscle and the liver, and the glucose and the triglyceride consumption during physical activities. A Randomized Block Design was applied with four treatments: control (K), physical activity (KF), physical activity and extract (FE),extract (E). The extract dosage was 400 mg/kg bodyweight/day administered for four weeks. The assessed variables were the muscle glycogen, the liver glycogen, the blood glycogen, and the triglyceride in the end of the treatments. Based on the research results, it was found that the muscle glycogen, the blood glucose, and the triglyceride of the E group were lower, whereas the liver glycogen was significantly higher than that of the control (K) group. The means of the muscle glycogen, the liver glycogen, the blood glucose, and the triglyceride of the control (K) group were respectively 0.41±0,01 μg/25mg, 0.22±0.01 μg/25mg, 85.89±2.45 mg/dL, and 32.00±3.38 mg/dL whereas of the E group were 0.39±0.01 μg/25mg, 0.26±0.02 μg/25mg, 75.84±2.29 mg/dL, and 23.39±2.08 mg/dL. After a physical activity of the KF group, the muscle glycogen and the liver glycogen decreased, however the blood glucose and the triglyceride increased significantly if compared to those of the control (K) group. The means of the KF group were respectively 0.14±0.01 μg/25mg, 0.09±0.01 μg/25mg, 164.73±11.07 mg/dL, and 66.31±2.96 mg/dL. After the administration of the extract to the FE group, their muscle and liver glycogen increased, but the glucose and the triglyceride decreased more significant than those of the KF. The means of the FE group were 0.35±0.01 μg/25mg, 0.19±0.01 μg/25mg, 107.05±7.79 mg/dL, and 40.00±2.30 mg/dL respectively. These results showed that during the physical activities, the energy was taken from the muscle and liver glycogen, whereas the glucose and the triglyceride were mobilized into the blood as the reserve source. After the extract administration, the source of the energy was taken back to the muscle and the liver, and then the glucose and the triglyceride were utilized. The compound within the extract is assumed to have influence on the activities of the enzymes involved in the metabolism of the carbohydrate and the fat. It can be concluded that the mangosteen rind extract recovers the muscle and the liver glycogen as well as increasing the glucose and the triglyceride consumption during the physical activities.
