The trends of modern endurance sports are a huge increase in the volume of training and intensity of loads for the athletes of young ages. According to the Federal Standard of the triathlon discipline, athletes aged 15-19 years of the highest sports qualification are required to train in the base period for about 25-30 hours a week. Of the total loads, most of them are given to swimming and running, to a lesser extent cycling, despite the fact that the duration of the cycling stage at all distances takes more than 50% of the competition time. The insufficiency of scientific research and justification in favor of redistributing loads by composite types of triathlon affects the performance of athletes compared to foreign colleagues. Russian triathletes, having high performances at international competitions at the age of 13-15 years at short distances, lose significantly in positions when moving to the top division and lengthening distances. There is also a high proportion of the end of sports activity, the inability to continue performing in professional sports due to monotony and high volumes of loads. In the course of the scientific work, the organization of the training process of the base period with the reduction of general training loads and the use of ski training in the role of power accentuated loads for the complex development of strength, speed and strength qualities was investigated. The control indicators in the work are lactate testing and the dynamics of the power indicator for a bicycle train, which were recorded at the stage of the control by means of modern digital devices and software, and the specialized survey of respondents is also used to assess the psycho-emotional state. The analysis of the results of the study showed a higher level of physical fitness of the respondents of the experimental group, explained not only by the new organization of training, but also by psychological factors.
