Anaerobic threshold is defined as the physiological point during exercise at which muscular lactate production exceeds the rate of lactate oxidation and as a result, lactate shows up in the system and may be balanced or not, depending on the intensity of the exercise. The purposes of the study was to determine the anaerobic thresholds level of female athletes in different distance of running. Ten female athletes, range between 22 to 24 yrs. age, having some previous experiences of training were considered as the subjects of that study. The measured variables were resting heart rate, speed for different distance and the Blood lactate. The blood lactate were measured by colorimetric method with LA Kit (Bioassay). The subjects were gone for eight-weeks scheduled extensive interval training programme. The data were collected as pre and post training manner. Significant difference has found in increased blood lactate accumulation in different gradual increase of running distance such as 250mt., 300mt., 350mt. and 400mt., both in pre and post training phase separately. But considering the training effect, there were the reduction (250mt.-1.98%, 350mt.-.30%, 400mt.-1.39%) of blood lactate accumulation except in 300mt.( increased 2.66%) but that were not significant in same distance of running after the extensive interval training. The conclusion may be drawn that the reasonable Extensive Interval training programme have positive impact on improvement of anaerobic threshold level reducing the blood lactate accumulation.
