Effect of Banana Isotonic Drink to Maintain Hydration Through Urine and Blood Electrolytes

Abstract

Banana isotonic drink is a potential beverage which has positive effect to maintain blood circulation. To make an improvement of product, clinical trials must be done in humans to know the effects of rehydration based on electrolyte analysis. This study used cross-over design with 7 days of washed out periods. Sixteen respondents, aged up to 20 years old and passed the selection of orthostatic test, were involved in this study. Changes in urine and blood electrolyte levels were checked before and after intervention. Electrolyte, include sodium, chloride and potassium, were measured using Easylyte. Data were analyzed with paired t-test and independent sample test. There were significant differences of urine level of chloride and sodium (p<0.05) after consumption plain water and banana isotonic drink. However, there was no significant difference (p>0.05) in urine level of potassium. Urine electrolyte decreased in all group after intervention. Meanwhile, potassium level increased after consumption banana isotonic drink. There were significant differences of chloride blood level (p<0.05) between plain water and banana isotonic drink. There were no significant differences (p>0.05) in blood level of potassium and sodium. Blood level of sodium and chloride decreased in all group. Meanwhile, potassium level increased after consumption banana isotonic drink. Banana isotonic drink was effective to maintain level of electrolyte in body by decreasing the level of electrolyte in urine output and improve potassium level.
