Possible judo performance prediction based on certain motor abilities and technical knowledge (skills) assessment

Sažetak
The influence of strength and agility and of the level of judo-related technical knowledge – judo skills – on the successful application of that knowledge in a bout - that is, on the performance in competition – was investigated on a sample of 131 physical education (PE) students of a judo class, aged 18-21, from Split, Croatia. The group of predictor variables consisted of: 9 measures of strength and agility, 2 measures of anthropometric status, and 2 grades of judo skills (technical knowledge). The individual judo performance (success) prediction probability, based on the proposed set of predictor variables, is fairly high. The general determination coefficient quotes 0.63, whereas the determination coefficient based exceptionally on motor variables quotes
0.30. The general judo skills grade alone (TEHNH) explains 54%, whereas the zempo kaiten fall grade (TMPAD) explains 24% of the entire judo performance (success in a bout) variability. The proposed group of the 10 predictor variables (9 measures of motor abilities and the zempo kaiten fall grade) explains 57% of the entire judo performance variability. Relative to the weight categories, the largest individual contribution to the explanation of the overall judo performance variability has been registered for the variables measuring arm strength. The examinees with the greater arm strength were more successful in fights because they had stronger arms to block their rivals’ counter actions and because they were able to impose their favourable preparatory postures to perform their techniques. Within particular weight categories the shorter, but heavier contestants were more successful – their arms were stronger, both relatively and absolutely, and they were more agile and manifested better judo skills (technical knowledge). The following manifest measures had a significant influence on the possible judo performance prediction: the judo skills (technical knowledge) grade, the arm and shoulder strength measure, manifested as the absolute, relative and static force application, and the ground coordination measure. It is feasible to consider these variables as relevant to judo. The zempo kaiten fall grade can be taken as a good relevant measure of the level of judo skills in beginners instead of the comprehensive technical skill grade.
