Influence of intensive interval trainning on lactate thresold level

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 ofthe exercisc. The purposes of the study were to determine the anaerobic thresholds level of female athletes in different distance of running after effect of intensive interval training. Ten female athletes, range between 22–24 yrs. age, having some previous experiences of training were considered as the subjects of that study. Thc measured variables were resting heart rate, speed for different distance and the Blood lactate. The subjects were gone for eight-week scheduled intensive interval training programme. The data were collccted 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, 3OOmt, 350mt, and 400mt, both in pre and post training phase separately. But considering the training effect, there were the reduction of blood lactate accumulation in every distance but in case of 250mt. only the reduction was significant. The conclusion may be drawn that the rcasonable Intensive Interval training programmes have positive impact on improvement ofanaerobic threshold level reducing the blood lactate accumulation.
