摘要：The aim of this study was to determine the influence of a system of motor behavior variables on set kata performance as the only criterion variable, and also to create a battery of measuring instruments for diagnostics, evaluation, monitoring and assessment of the kata performance based on their predictive validity. Eighty-two boys training karate, aged 10-14, were tested by using 12 motor variables, and 1 criterion variable. The variables' individual validity was determined by the stepwise regression analysis. The results indicated that the system of basic motor variables had a statistically significant influence at p=.00, with a multiple correlation coefficient of .67 (Ro= .67), and multiple correlation squared of .45, explaining about 45% (Ro2= .45) of the variance. Based on the analysis of individual predictive motor behavior variables, the following had the greatest and most significant influence on the criterion variable: 30s sit-ups, the standing broad jump, 20m run, foot tapping, deep forward bend on the bench, and standing triple jump. The stepwise method isolated a reduced system of the same five motor behavior variables. According to these findings, the following battery of measuring instruments for diagnostics, evaluation, monitoring and assessment of the kata performance is recommended: the standing broad jump, standing triple jump, 20m run, 30s sit-ups, and hyperextensions on the bench.
