Background: Lactate buildup and out flowing energy is one of the most important physiological phenomena used to explain athletes' response to better performance, especially in activities that depend on the lactic system for energy production. This is in light of the recent trend that lactate is not the main source of fatigue and is an energy production system, the reason for the increase in acidic muscles and poor ability to perform is dissociation into lactate and the H+ ion. Aim: Design a training program identify performance changing while increasing in blood lactate. Methods: Experimental study on 8 boxers from the of Mini a University team. Data were collected by using Accusport Lactate Analyzer, Arm pedometer. Results: Increased blood lactate post the program as it reached (0.042) p<0.05, Increased punching rate as it reached (0.043) p<0.05 where statistically significant differences. Conclusion: better physical performance with high rates of blood lactate, Boxers can withstand high concentration of blood lactate during physical exertion. Increased blood lactate to increase the tolerance of performance in boxers, H+ ion is the cause of fatigue and not blood lactate.
