The accumulation of an enormous amount of lactic acid in the blood is one of the causes of exhaustion for athletes after vigorous exercises, particularly short time exercises with the maximum of speed and intensity. Considering the need of athletes to reach the natural conditions and to be ready for subsequent activities, methods of lactic acid disposal are of high importance. The purpose of this study was to determined The effect of high intensity anaerobic training on the blood lactate levels after recovery. This quasi-experimental research, pre-tested and post tested 60 male athlete students. The athletes randomly were divided into four groups of 15 including the first group to do initial inactive recovery, the second to fourth to do initial active retrieval with the intensity of 55, 60, 65 percent Maximum heart beat . The groups were evaluated by Cunningham test and their blood lactic acid was checked in four phases by manual lactometer( before activity, immediately after the activity, 5 and 20 minutes recovery period the initial situation). There was no significant difference in the average amount of lactic acid blood of athletes in all groups at rest and immediately after activity, but five minutes after initial recovery and twenty minutes after that they were significantly different(P <0.001, for both times). The average of lactic acid in blood twenty minutes after initial recovery was the highest for the inactive group, and the lowest for the group with 60 percent of maximum heartbeat. Also a decrease in lactic acid level five minutes after recovery to twenty minutes after that for the group with 60 was significantly more than the group with 55 percent of maximal heartbeat; and the decrease in the level of lactic acid in group of 65 percent of maximal heart beat was significantly higher than the group of 55percent of maximum heartbeat (P <0.001). The result of this study shows that the initial state of recovery through activity effects is better than passive state. Additionally, doing exercise with is 60 of maximal heart rate in during recovery is the best way for reducing blood lactate.
