The rehydration potential of zea mays juice compared to carbohydrate-electrolyte beverage

The purpose of rehydration is to replace fluid and electrolyte losses. Carbohydrates and sodium are the main nutrient sources for rehydration. The presence of protein aids the rehydration process and thereby promoting muscle synthesis. Zea mays had been identified as one of the potential food sources that could be an alternative recovery beverage. The aim of this study was to assess the potential of Zea mays (ZM) juice as an alternative rehydration beverage. A total of 15 male participants were involved in this study. They were required to cycle to 70-80% of their age predicted maximum heart rate until they were dehydrated (1.8-2% body weight loss). Then they were given either ZMjuice or CE drink in an amount representing 150% of their initial body weight loss. After 4-hours of rest with no other food allowed, their USG and percentage of fluid retention were calculated. Results showed that ZMjuice had better retention and demonstrated well hydrated USG readings compared to CE drink. Therefore, ZM juice has the potential to be an alternative rehydration beverage.
