Effects of postexercise supplementation of chicken essence on the elimination of exercise-induced plasma lactate and ammonia.
We investigated the effects of chicken essence (CE) supplementation on exercise-induced changes of lactate and ammonia during recovery. In this randomized, double blind, crossover study, twelve healthy subjects performed a single bout of exercise to exhaustion, and then consumed either a placebo or CE within 5-min of the exercise cessation. Blood samples were collected before exercise, at exhaustion (0 minute), and 20, 40, 60, and 120 minutes, respectively during the recovery period. There were no differences in plasma glucose, creatine kinase, or heart rate responses between treatments. The exercise exhaustion significantly increased the levels of lactate and ammonia, and both measured values gradually declined during the recovery period. Ammonia levels at 40, 60, and 120 min. of the recovery period were observed lower significantly in the CE group, as compared to those in the placebo group. Additionally, lactate concentrations at 60 and 120 min were lower in the CE group, as compared to those in the placebo group. In conclusion, the main finding of this study was that CE supplementation after exercise reduces plasma lactate and ammonia levels. The results indicated that CE supplementation after an exhaustive exercise could enhance physiological recovery in humans.
