THE APPLICATION OF ROLLERBLADES IN ALPINE SKIERS TRAINING

Skiing as a seasonal sport has limited abilities of specifi c training. Therefore it is desirable for “dry” trainings to have a certain degree of similarity of competitive technique movements’ simulation. Exercises must be in accordance with the parameters that determine the structure of movement on skis. The subject of this paper is to determine the possibility of including the training on rollerblades as an integral part of „dry” training. By analyzing the previous studies it has been tried to establish the extent to which the basic parameters concur with the elements of ski slalom technique (SL) and rollerblade slalom (ISL): positions and relationships between body segments, activities of current muscle groups (mode, degree of activation) and kinematics of movement (duration of certain phase shifts) and others. The results of previous research indicate coordinative propinquity of reverse-route technique on skis and on rollerblades. Certain differences in speed, intensity of force, load points, as well as similarities in the positions of body segments, the involvement of actual muscle groups, the intensity of muscle tension and others are evident. The knowledge of the similarities and differences can improve the application of rollerblades in training of skiers. Changes in some parameters (slope, speed) can contribute signifi cantly to the positive transfer when the structure of movements in skiing is in question.
