The Impact Of Carnosine Complex On Anaerobic Capacity And Metabolism

Objectives:To investigate the impact of Carnosine complex on anaerobic capacity, and approach the mechanism of impacting sport ability through assaying the value of LA, MDA, GSH-Px, urine pH and UA.Methods:Twenty-seven soldiers who picked out from one company were asked to complete training and 2 tests. The normative warm-up exercise was completed by aerobic bicycle, and anaerobic capacity test by anaerobic bicycle, the load is weight (kg)X 7.5 %. The subjects were randomly separated into 3 groups according to the result of the first test. After taking the relative samples (dietary fiber, sodium bicarbonate, Carnosine compound), they started the second test, and the condition is same in the two tests. The peak power and average power was collected by Monark Anaerobic Test Software. According to the result of preexamination and relative literary, we assay the value of LA after the movement for 10 min and 1 hour, the value of urine pH after movement for 1 hour and 2 hour, the value of MDA GSH-Px UA after the movement for 1 hour and 2 hour.Results:(1) Average power of Carnosine compound group and sodium bicarbonate group was higher than the control group. (2)10 min after exercise, the lactic acid value of Carnosine compound group and sodium bicarbonate group was apparently higher than control group. (3) The urine pH value of sodium bicarbonate group was higher than the other groups. (4) The value of MDA in 1 h and 2h after exercise was increased in control group and sodium bicarbonate group, but no difference was found in Carnosine compound group. The value of GSH-Px of Carnosine compound group was higher than control group and sodium bicarbonate. (5) After 1h and 2h after exercise, UA value of Carnosine compound group was lower than control group and sodium bicarbonate group.Conclusion:Carnosine complex and new sodium bicarbonate preparation administration can improve 1 min maximal anaerobic capacity and. lactic acid value. Carnosine compound can reduce the level of MDA and UA, raise the level of LA and GSH-Px, and sodium bicarbonate can improve the value of urine pH, but it has no effect on oxidation and metabolism of UA. We can infer that increasing anaerobic capacity of Carnosine compound is through buffering action and antioxidation。...
