Title: Analysis of the techniques and methodology of cross-country skiing for the visually impaired. Aim: The aim of this thesis is to create a set of training exercises in the snow for practicing the classic technique of cross-country skiing for the visually impaired. Methods: It is an empirical and theoretical work, which is based on an analysis of the movement of the visually impaired in cross-country skiing of classical technique. The structure of the work is led as qualitative research. To achieve the objective, we used observations, field measurements, photo and video documentation through digital cameras GoPro brand. Based on the analysis of movement each proband was evaluated from particular monitored exercises and based on the evaluation they got recommendations for training exercises on the snow. Results: With processing and subsequent evaluation of equilibrium and coordination exercises control, we found that visual impairment has a decisive influence on the balance on one ski and coordination of arms and legs which is the source of technical shortcomings. Conclusion: Based on the results of our work, we proposed a supplementary preparatory equilibrium and coordination exercises. Keywords: visual impairment, classic technique, cross-country skiing

Title: The reflection kinesiology analyse of cross country skiing Purposes: To compare coordination of chosen muscles on leg during reflection of cross country skiing classic technique, skating and herringbone. Methods: Comparative analysis: the dates were measured by surface electromyography and 2-D video-analysis. Results: We founded statistical significance by comparisons muscle activation on right leg during kick during cross country skiing: classic technique, diagonal stride and herringbone and V-1 skating and herringbone. In case the left leg the statistical significance was disprove by: m. peroneus longus sin during comparison of diagonal stride and herringbone and m. gastrocnemius medialis sin V-1 skating and herringbone. We founded high level of laterality of diagonal stride and herringbone. In case V-1 skating, the significant similarity was not founded for m. vastus lateralis and m. gluteus medialis. Key words: Cross country skiing, classical technique, skating, herring bone, kinesiology, surface electromyography (EMG), muscles activation
