The main task of the coach and the athlete is to increase the effectiveness of training programs, which is only possible by selecting certain training regimes. For this, it is necessary to understand the peculiarities of the energy supply of muscles during different intensity and duration of physical activity. Effective training is possible only with a correct assessment of various aspects of the functional readiness of athletes and understanding which of them limit the growth of sports results, in particular lactate threshold, VO2max, complex cardiac indicators etc. This is especially important for young athletes who need to develop those qualities of the body that will help them to achieve success. The purpose of the study was to give a theoretical substantiation of the need to activate the anaerobic threshold in young athletes in order to increase their endurance in cyclic sports. Material and methods. The study involved five 12-14-year-old female cyclists, with a training experience of 2-3 years. Before the experiment, control races were carried out on an almost horizontal section of asphalt road 1.5 km long in calm weather in order to calculate the strength of the cyclists so that the subsequent ride would be performed with greater intensity. Each participant performed 3 races after 6-7 minutes of rest. Only the first participant was able to complete the task correctly. Results and discussion. The experiment had been carried out during two months before the competitive season, using the interval method on incomplete recovery with the duration of intervals of 1-3 minutes. The work of young cyclists was carried out in a mode close to the lactate threshold with duration of 90-120 seconds on a cross-country track and consisted of a series of three intervals. During one training, depending on the level of athletes' fitness, from two to six series were performed. Taking into consideration the young age of the cyclists, such trainings were carried out on average once every 10 days. On the second day after such glycolytic training, a light aerobic training was carried out at a heart rate of 55-60% max for the recovery of athletes. The rest of the training time was devoted to improving aerobic endurance, the technique of passing difficult sections, overcoming hills. A week after the completion of the study, control races were carried out under similar weather conditions. Comparison of the results of control and experimental races shows that the average decrease in the time to complete the races, which was 6.1%, was not always connected with the increase in heart rate - 4.5%, that is, the work of athletes in the submaximal power zone allowed them to improve the individual competitive result in simulated conditions. Conclusion. Thus, for young athletes in the postpubertal period the method of short intervals should be used, because it affects the increase in the lactate threshold and gives an increase in results
