THE IMPACT OF THE INRUN POSITION ADJUSTMENT ON THE IMPROVEMENT OF THE SECOND AND THIRD PHASE IN SKI JUMPING.

Ski jumping requires great precision during the execution of each of its four phases, as a result of its complex technical components. The objective of this study consists in the improvement of each athlete's technical skills focused on the first phase, with a view to creating the pre-requisites for the improvement of the second and third phase. To achieve this, we used various specific training tasks consisting of imitative exercises applied continuously by using the proprioceptive method, as well as jumps on the HS 71 and HS 100 hills, with specific tasks for the first phase of the jump for each athlete. The evaluation of the ski jumpers' performances was completed objectively in different positional aspects specific to the first phase for ski jumping. The success in adopting and maintaining the inrun position while passing through R1, under the exerted forces on the jumper-ski system and focusing on the correct distribution of the general mass center, created the possibility of improving the indicators of sports performance in the individualized training process.
