Administration of Pismatom Juice Decreasing of Malondialdehyde Concentration In Middle Run Athletes of PASI Denpasar, Bali-Indonesia

Abstract

Physical exercise with high intensity and prolonge causes oxidative stress which is possibly related to fatigue for athletes. Oxidative stress caused damage to cells which is marked by increasing of lipid peroxidation which will then be decomposed into malondialdehyde (MDA) in the blood. The objective of this study was to prove that administration of Pismatom juice (mix of banana honey and tomato) decreasing of MDA in middle run athletes. Subjects of this study were 28 males athletes divided into 2 groups with randomized pretest-posttest control group design. Treatment group was given Pismatom juice before and after physical exercise with 240 of volume and control group was given mineral water before and after physical exercise with 240 cc of volume during 14 days. The MDA was quantification with TBARS method. The analysis of treatment effect was conducted by t-independent and General Linear Model (GLM). The results of this study showed that MDA levels decrease significantly in the treatment group with Pismatom juice was average 1,88 + 0,167 mM/L and control group was average 2,13 + 0,414 mM/L with p value = 0,046 (p<0,05). It was concluded that administration of Pismatom juice has antioxidant effect  for decreasing of MDA concentration in intense physical exercises in middle run athletes.
