Zavadil, Jan ; Pavelka, Radim (advisor) ; Smolík, Petr (referee)
Title: Kinesiological analysis of tachi-waza technique in judo Objectives: The aim of this work is to measure activity of selected back muscles and oblique abdominal muscle using surface EMG. At the same time, determine the load with comparison with the maximum free contraction for musculus erector spinae with selected judo techniques tai otoshi, o goshi and uchi mata. Then perform intra- individual comparisons between different techniques and comparisons between measured probands. Methods: To determine the muscle chain in a motion cycle in techniques tai otoshi, o goshi and uchi mata by surface EMG method and kinetic analysis. Six probands with several years of experience in judo were selected to measure. The measurements were four muscles on both sides: musculus trapezius, musculus erector spinae, musculus latissimus dorsi a musculus obliquus externus abdominis. Results: There was some similarity for intra-individual comparison. Three probands between the technique tai otoshi and o goshi, two between tai otoshi and uchi mata. Can be assumed, that techniques tai otoshi is basic technique with which the probants began in their youth. In the inter-individual comparison, the results showed, that the technique is very individual. Most muscles involved 80% of the average motion cycle. Most often at the...

Title: Frequency and success of selected techniques in elite judo competitions Objectives: The main aim of this study is evaluated judo techniques uchi-mata, tai- otoshi and o-goshi. The study shows, which techniques is the most common and which is the most successfully in elite judo competitions. These variables were studied in all weight categories both men and women and the time of fight were studied as well. Methods: In study was used observation method in four elite judo competitions. I observed frequency of selected techniques and their scoring. These data was converted on percentage use and percentage of success for all selected techniques. Data was analysis by ANOVA. Results: I found that uchi-mata is very often techniques. In the middle part of fight the competitors the most often attacks and the most often scores. The differences between weight categories was detected, however, I did not recognize distinct trend. I did found significant differences between men and women nor in frequency neither in success of selected techniques. Keywords: judo, uchi-mata, o-goshi, tai-otoshi, elite competitions
