Abstract

Background and Study Aim: The main aim of the study is to determine a factor structure of the state of systems of energy provision for effort of judo athletes at various stages of long-standing training. In each group four factors determining the structure of the system of energy provision for the athletes' effort were identified, and their most informative indices were determined.
Material and Methods: The paper presents the results of factor analysis of the state of the energy system in three groups of female judo competitors: Polish national team representatives in the group of seniors, Polish national team and Pomerania Province team representatives in the group of juniors (16-18 years old), and Pomerania Province team representatives in the group of sub-juniors (13-15 years old). The anaerobic capacity was assessed using the 30-second Wingate test applied to the subjects’ legs. To assess aerobic capacity at laboratory, the test of increasing load up to exhaustion was used.
Results: In each group the factor structure revealed specific characteristic properties. On the one hand, they indicate specific significance of relations between the indices of anaerobic and aerobic provision for the competitors' appropriate sports level. On the other hand, they indicate a greater significance of relative indices of anaerobic efficiency in comparison to their absolute values.
Conclusions: The presented results should be regarded from the perspective of their theoretical significance and from the perspective of practical application in further research connected with the issue of increasing the effectiveness of judo competitors' training process at various stages of long-standing sports training
