Consumption of a carbohydrate (CHO) beverage during prolonged exercise has been shown to maintain plasma glucose levels. The purpose of this study was to examine the effects of a coconut beverage on blood glucose and lactate levels. Eleven endurance trained males participated in a repeated measures randomized double blind study. Each subject completed a VO2max followed by three 90 minute trials on treadmill run at 60-70& of their VO2max, while consuming one of three beverages per trial (W=water, G=carbohydrate beverage, CB=coconut beverage). Every 15 minutes the subject drank 12 ounces of the beverage. A treadmill anaerobic test (TAT) was performed at completion of each 90 minute run. Blood glucose and lactate were measured at baseline, 15 min, 30 min, 45 min, 60 min, 75 min, 90 min, Post TAT, 5 min Post, and 10 min Post. There was a significant difference (p<0.05) found in blood glucose between W and the CHO supplements (G & CB). No significant difference was found between the G and CB (p>0.05). No significant difference (p>0.05) for lactate was found between any of the three beverages (W, G, CB) in terms of measured lactate concentration throughout the trial. Supplementing with CB can provide the same benefits as G in maintain blood glucose.
