Interval training method for developing special endurance in orienteering athletes aged 13 to 16 years

The purpose of the study is to develop a program of interval training on sandy surfaces in the conditions of a rugged terrain course to enhance the level of special endurance among athletes in orienteering aged 13-16 years. Research methods: analysis of scientific and methodological literature, pedagogical observation, surveys, pedagogical experiments, methods of mathematical statistics. Research results and conclusions. The insufficient volume of work on the development of special endurance in the training process of orientation athletes affects the effectiveness of the athletes' performances. The application of interval training on a rugged terrain with a sandy surface for orientation athletes aged 13-16 has proven effective in increasing the level of special endurance development and improving performance in the 1000-meter run and in the control distance (competition course).
