Sažetak

Water polo, as an activity, belongs to the category of polystructural complex move sports. The activities of a central player were sampled during competitive games of the First National League. The study is aimed to define a set of new measurement variables for the objective recording of the amount, intensity and duration of player's activities, and its evaluation by means of factor validity criteria. On the sample of 91 entities, 29 variables were applied. Measurements were made by competent, trained officials. Basic statistics of all measured variables is presented as referral values of various player activities. In the factor analysis, three factors are found to be significant explaining 84.6% of source variability, which is a subset of multivariate normally distributed variables. Factors are interpreted as: Quantity of actions, Intensity of activity in the horizontal body posture, and the time spent in a game. Of the first two, body posture is found to be specific in water polo, due to specifics of the game played in water. It is concluded that the proposed variables and measurement procedures are very well suited and objectively instrumented, for the purpose of measurement of the energetic aspect of kinesiological activity analysis.
