Introduction. Practical experience shows that at present, in the technical training of double-skiers, the main attention is paid to the jumping component. In this connection, the development and scientific substantiation of the methodology of technical training in the racing component is an urgent task and a significant reserve for improving performance.
The purpose of the study is to evaluate the effectiveness of the technique of technical training of cross–country skiers.
Methodology and organization of the study. At the beginning and end of the pedagogical experiment of 2020-2022, pedagogical tests on skis were conducted, including three control exercises. The recommended exercises [1] were performed on flat terrain, descents and ascents of small steepness. Their coordination complexity and variability were ensured due to changes in external factors, interaction with partners and the use of additional inventory.
The results of the study and their discussion. The results in the "shuttle cross-country skiing" showed that young dual skiers after the experiment began to actively cross their legs with a tilt of the trunk in the direction of the turn, and also stopped making a high swing with sticks. As a result, athletes significantly faster (p< 0.05) began to overcome the specified distance – 24.87 ± 1.7 s and 20.30 ± 0.98 s – before and after classes. When moving with a simultaneous stepless stroke, the duration of the movement cycle decreased in EG athletes – from 0.82 ± 0.10 s to 0.70 ± 0.08 s – and the time of pushing off with hands – from 0.45 ± 0.07 s to 0.37± 0.02 s. In the case of skating without pushing off with sticks, the double-skiers of the EG began to stand more steadily on the supporting leg, to move the body weight from one leg to the other in a timely and complete manner, which was positively reflected in a decrease in the time of squatting – from 0.48 ± 0.11 s to 0.31 ± 0.13 s – and an increase in the step length – from 3.66 ± 0.36 m up to 4.02±0.47 m. Reducing excessive vibrations of the trunk contributed to the development of greater speed and shorter travel time. All changes in CU are statistically significant, p<0.05.
Conclusion. Purposeful technical-oriented classes, including exercises on racing skis, roller skates, roller skates, imitation of ski moves, as well as games and relay races with elements of skiing technique, have allowed to increase the level of technical readiness of biathlon skiers engaged in the training stage.
