Acute physiological responses and performance following subsequent CrossFit ‘CINDY’ workout with Zea Mays juice




Zea mays, recovery beverage, performance, physiology responses


Purpose: The purpose of this study was to investigate the physiological responses and performance following subsequent repeated high intensity exercise with consumption of Zea may juice ( ZM ) Materials: Total of seventeen participants involved in the study. They were physically active who had cardio and strength training at least 3 times per week. The age of participants was 21.8±1.7 years old, body weight 65.4±11.2 kg and height 169.7±7.2 cm. Crossfit ‘CINDY’ exercise were repeated between two hours of rest. Treatment beverage of ( ZM ) juice vs Carbohydrate-electrolyte (CE) drinks were consumed immediately after exercise in double blind cross over manner. Number of complete set of exercise, heart rate, blood lactate and rate of perceived exhaustion (RPE) were recorded at the end of each exercise session. Results: Total number of complete ‘CINDY’ exercise significantly increased in ZM juice group during second bout of exercise compared to CE drink group. There were no significant difference in heart rate, blood lactate and RPE in both groups Conclusions: ZM juice has potentials an alternative recovery beverage to promote subsequent repeated exercise within short rest time.
