Study of the Implications of the Ski Jumpers Technical Behaviour during Start and Inrun Position on the Enhancement of the Sliding Velocity at Jumping Hill Table Takeoff - Training Stage II

Abstract

Mastering the optimum technique is an essential prerequisite in ski jumping for achieving long jumps, flights, and aerodynamically efficient as well as aesthetical trajectories - in terms of form and gesture expression. To accomplish these desiderata, it appears necessary that the jumpers are offered favorable premises at the very instant of event initiation, both for developing an increased gliding velocity at the hill table takeoff and also for optimum global and segmental body posture, in order to allow the forming of the correct technical mechanisms entailed by the takeoff and flight phases, respectively. All these actions take place at the start instant during the practitioner’s movement along the inrun section. The start and especially the quality of the inrun position represent teaching-learning contents towards which many trainers – especially those with lesser international experience – adopt a superficial attitude which leads to negative consequences on sportive efficiency. The present paper describes the fundamental theoretical-methodical issues of the technical contents and their way of implementation during the training process along with the didactical methodology needed for qualitative upgrading of the time sequence prior to the jumper’s table takeoff instant. The objective assessment of the proposed methodology was accomplished by measuring the dynamics of the velocity values at the jumpers’ hill table takeoff instant in terms of applying specific training means during a compact training period consisting of imitative and proprioceptive exercises.
