The main of this study was to in vestigate the effect of my three weeks of HTT exercise on lactate peak time and also Vo2max adolescent girls were in active which are randomly divided into 2 practice groups (8 people) and control group (8 people) were divided. The present study is a cross- sectional (8 people) were divided. The present study is a cross- sectional experimental study which was performed in the whit pre-and post test design. Befor and after the exercise program, the subjects of both groups performed an incremental test to determine the maximum oxygen consumption. The control group had no activity but the experimental group tested the anerobic speed as (RAST) the protocol performed four sessions per week for lactate peak times. Blood lactate at pre – test times and at zerominutes of (recovery start) 2, 4, 6, 9, 12, 15 measured with alactometer. Data analysis was performed using ANOVA statis tical test. The ANOVA test showed that 3 weeks of HIT exercise was the peak time of blood lactate and Vo2max increased significantly.
