The aim of this research was to establish a relationship between motor skills andperformance of specific elements in handball. A battery of 18 motor skills tests was assessed on thesample of 58 male subjects, students of Faculty of Physical Education and Sport, aged 21-23years.Variables of coordination, figure eight running drill with bending under rope, lateral shuffle,agility on the floor, and agility in the air, all indicate to negative projection on the first isolatedcanonical factor, as do the two flexibility tests, shoulder and chest opener with rod and standingshoulder extension were applied as predictor variables and two tests dribbling around thecones (Metikoš and al. 1989) and throwing the ball against the wall (Rogulj and al. 1995).Theoverall results of the canonical correlation analysis indicated to the evaluation of the appliedcanonical model on motor tests in relation to the performance of specific handball elements,to the canonical correlation value of 0.765, with the Chi-Square test value of 320.101, and tostatistically significant correlation of used variables on level p .008. Through further analysis,4 canonical roots were extracted, out of which only the first one was statistically significant (p.008). Through observation of data on the correlation between motor variables and canonicalroots, it can be concluded that the MRCZTL (0.58) and MFEBML (0.56)variables have thehighest projection on the canonical factor, and thus are also most significant in conditioningthe results achieved. Also the MAGKUS (0.55), MBFTAP (0.51) and MBAU1Z (0.51)variables has statisticaly significant results in conditioning the results achieved.Results of thisanalisys are ppointing to the fact that the subjects with lower degree of those motor skills havealso had lower performance of specific handball elements, indicating the need for greater engagementof motor skills in performing the aforementioned elements.

SummaryAs part of a population study on chronic lung disease in the Netherlands, an investigation is made of the relationship of both age and sex with indices describing the maximum expiratory flow-volume (MEFV) curve. To determine the relationship, non-linear canonical correlation was used as realized in the computer program CANALS, a combination of ordinary canonical correlation analysis (CCA) and non-linear transformations of the variables. This method enhances the generality of the relationship to be found and has the advantage of showing the relative importance of categories or ranges within a variable with respect to that relationship. The above is exemplified by describing the relationship of age and sex with variables concerning respiratory symptoms and smoking habits. The analysis of age and sex with MEFV curve indices shows that non-linear canonical correlation analysis is an efficient tool in analysing size and shape of the MEFV curve and can be used to derive parameters concerning the whole curve.
