The purpose is to analyze the relationship between space-time indicators and the structure of jump cycles for jumpers of various qualifications to adjust and improve the training process and achieve results in responsible competitions.
Research methods and organization. To achieve the purpose, the following research methods were used: the study and analysis of scientific and methodological literature, pedagogical observation, analysis of video materials of competitive activities of jumpers, mathematical and static processing of research results. The research was conducted on the basis of Churapcha Republican Secondary Sports Boarding School of the Olympic Reserve and Churapcha State Institute of Physical Culture and Sports. Video shooting of the Yakut jumping technique was carried out with the use of the Phantom 3 Professional quadrocopter, which has HD video quality in up to 4K resolution with a maximum resolution of 4000x3000 and shoots at a speed of 30 frames per second.
Results and discussion. Analysis of the Yakut national jumping technique allowed us to establish that eleven non-stop jumps require a high jump stability, associated with the coordination of movements and the speed of overcoming the distance. Comparison of the data of the support-flight jumping phase in jumpers of different qualifications allows us to judge the degree of fitness for competitive activities. When analyzing the time characteristics, we found significant differences in the duration of the flight and the support. Analyzing the competitive activity of jumpers, we found that with the performance of each subsequent jump, there is a dynamic decrease in flight time. The decrease in flight for 1st- category jumpers is 4%, and for 2nd-3rd-category jumpers - 5.7% relative to the flight time for masters of sports of the Republic of Sakha (Yakutia); the support time, respectively, for jumpers of the 1st-category is 11%, for jumpers of the 2nd-3rd category - 22.4%, which is explained by the decrease in the repulsive force of jumpers of different qualifications.
Conclusion. As the data of the analysis of space-time indicators of jumpers of various qualifications show, one of the leading components of achieving high results can be both the flight time and the support time. It is worth noting that the achievement of the result in highly qualified jumpers occurred due to the stability of the jump length both in the first and in the second half of the jump cycles. It contributed to the achievement of high results by the athlete. The results obtained can be used as reference points for the level of fitness when planning the training process.
