Sažetak

The relationship between cognitive factors and performance in volleyball was investigated in a group of 53 male subjects positively selected for cognitive abilities and with an average knowledge of the game of volleyball.
The data were analyzed by quasicanonical (QCR model) and regression (SRA model) analysis. The results of the analyses did not show any significant correlation between cognitive factors, defined as efficacy of the perceptive, parallel and serial processors, and performance in the game determined by the subjective evaluations of judges for technique, attack, defence, creativity, responsibility, commitment, control of behaviour in accidental situations and overall performance. Moreover, both the greatest quasicanonical correlation and the multiple correlation when the set of cognitive factors was used to predict individual evaluations were not significant.
However, in the quasicanonical anlysis of the relationship between cognitive factors and situational-motoric factors extracted from objective tests which are in the main similar to elements of the game of volleyball, a small but significant correlation was found between cognitive abilities and ability in volleyball defined in this way.
The greatest quasicanonical correlation of 0.255 was significant at the p=0.05 level. The basic carriers of this correlation were the factor of serial processing from the set of cognitive factors and the factors of precision of passing and hitting the ball with the forearm frm the set of situational-motoric factors precision of smashing and power with which the ball is hit.
The part of the variance of the situational-motoric factors mentioned may be attributed to the efficacy of estimating the path of the ball's motion, efficacy of estimating the moment in time at which to start a motoric action and the efficacy of determining the trajectory of the ball towards a target. These cognitive abilities are mainly of the serial type. The correlation between cognitive factors and situational-motoric factors is therefore explained by the participation of serial processing in the performance of elements of the game of volleyball which an incoming ball is hit in the direction of the required target.
In further investigations especial attention should be given to the relationship motoric endurance and cognitive factors in selected subjects. Namely, the situational-motoric factor of speed endurance of volleyball players showed a negative correlation with the group of cognitive factors which is in accordance with the results of canonical correlation analysis of cognitive factors and basal motoric factors on the total sample of subjects of this investigation. There are factors subordinate to the mechanism on which motoric endurance is dependent were also negatively correlated with the factors of intelligence. So far no satisfactory explanation has been found for this phenomenon.
The next phase of the investigation should also confirm the correlation between cognitive factors and performance in elements of the game of volleyball after partialization of the variance of morphological factors since the results indicate the possibility that most of the correlation is masked by the influence of morphological factors of performance.
