    Kinematic parameters are an indispensable segment in the analysis of all throwing disciplines, including javelin throw. They are also an indicator of possible differences between competitors of different or the same rank of the competition and are an important factor for achieving a good result. The aim of the study was to determine the spatial and temporal differences of kinematic parameters in the javelin throw between the male and female finalists of the World Championships. Methods: The study was conducted on a sample of finalists in the World Athletics Championships (Berlin 2009-Daegu 2011) with the aim of determining the differences between the kinematic parameters of the male and between the female javelin throwers. The sample included a total of 32 competitors in both categories. To obtain the necessary results, a t-test for independent samples was applied. Result: statistically significant differences were confirmed between male finalists in 60% of kinematic parameters: release velocity (t=3,504; p<0,004), angle of yew (t=4,664; p<0,000), length of delivery stride (t=2,444, p<0,028), distance to foul line (t=5,120), duration of impulse stride (t=-4,462, p<0,001), duration to release (t=-4,837, p<0,000). In women, significant differences in 40% of parameters were confirmed: angle of release (t=-,365, p<0,005), angle of yew (t=9,182; p<0,000), duration of impulse stride (t=-4,140, p<0,001), duration to release (t=-4,409, p<0,001). Conclusion: Generally speaking, this research showed that significant differences were observed between male finalists and between female finalists. Mostly, these are kinematic parameters that have proven to be paramount in the resultant performance of these championship throwers. One should not forget the influence of exogenous factors, above all air currents and javelin behavior as an aerodynamic device. An ideal biomechanical model of the thrower can be made based on the differences in the kinematic parameters of the top medal winners at the Berlin WCh in 2009 and the Daegu WCh in 2011.

    ESTIMATION OF IMPACT AND DIFFERENCES BETWEEN TWO GENERATION STUDENTS IN THE BIOMOTOR ABILITIES OF THE FACULTY OF PHYSICAL EDUCATION SPORTS AND HEALTH IN SKOPJE

    Research has been done in a sample of 94 respondents, consisted of full-time second year students at the age of 20 years with ± of 6 months at the Faculty of Physical Education Sport and Health in Skopje, divided in two groups of 47 respondents in both generations surveyed - 2013/14 and 2014/15. Respondents from both generations regularly attended athletics classes, meaning they had passed the methodology and technique of 15 athletic disciplines. To accomplish the purpose of the research, 15 athletic disciplines divided into two colloquiums, athletic pentathlon and five athletic disciplines for the exam in June were used. The practical part of the exam is the remaining 5 athletic disciplines, but also those disciplines that did not pass in both colloquiums. The results of the two generations of respondents are first processed with descriptive statistics - minimum, maximum score, central value, standard deviation and skewness and cortisone graphical representation of the results. The grades for each discipline of each respondent are processed, as well as the final assessment of the practical part.Based on the multivariate analysis on the results of both groups of entities we can conclude that both groups of respondents differ in their biomotor abilities which in this research are analyzed through motor variables which are of great importance for the successful completion of the practical part of the subject athletics. The differences between the respondents would be smaller if they paid more attention to the preparation for the practical exam.
