The aim of this study was to examine connection between the motor ability strength and the achievement of results in sprinting in order to define strength tests to perform selection in physical education classes, at the age of early puberty. The sample consisted of 88 female subjects aged 12 years (± 6 months). The batery of four tests was used for evaluation of the motor ability strength, prescribed in the curriculum for the subject Physical Education of the Pedagogical Association of Vojvodina: variables of explosive strength standing broad jump (cm), throwing medicine ball from lying position (m), variable of repetitive strength sit-ups (number of successful attempts) and variable of isometric strength bent arm hang (s). For evaluation of the motor ability speed, the standardized test was applied, which represented the criterion variable the result obtained in 60 m run (s). The relationship between the system of predictor variables and the criterion variable is calculated by linear regression analysis, and the results showed that, on the basis of the results of the predictor variables system, the level of sprinting speed can be statistically significantly predicted. By observing the individual variables, it can be seen that the variables standing broad jump (p=0.00) and sit-ups (p=0.00) achieve statistically significant prediction of 60 m run speed. By analyzing the results of regression analysis, it can be assumed that the result of the 60 m run in selected subjects can be predicted based on manifestation of explosive leg strength and repetitive strength of torso.

The aim of the study was to determine and verify the effectiveness of various teaching approaches on changes in the level of volleyball performance in the process of teaching volleyball to pupils in primary schools. In the experimental group was used the tactical approach and in the control group the techniques (traditional) approach in teaching of volleyball. The experimental group consisted of 26 pupils and the control group consisted same number of pupils. Both groups, representing 13 to 14 year old schoolgirls in primary school. Efficiency of the teaching approaches was evaluated based of game performance. Game performance was evaluated by the method of game performance assessment based on GPAI (Game Performance Assessment Instrument) through video record. To perform statistical evaluation Mann-Whitney U-test was used. When we evaluate the tactical component of game performance “position”, we found out that the difference between groups is not statistically significant (p > 0.05). By comparison “decision-making” it was discovered that the difference, between achieved performances in groups it is statistically significant (p < 0.05) in favour of the experimental group. By comparison skills execution we found out, that the difference between both groups in “serving” is not statistically significant (p > 0.05). But by comparison of passing, setting, offensive hit and team’s game performance” we found out statistically significant (p < 0.05) the difference between both groups in favour of the experimental group. The acquired data pointed to the fact that in generally the tactical teaching approach appears to be a more efficient method for acquiring game skills and tactical components of the game.

In order to have successful technical analysis athletics uses modern biomechanical methods, and the obtained results are subjected to numerous analyzes. On the basis of the results of biomechanical parameters the most successful motor structure techniques of a competitor can be planned, programmed and analyzed, and based on this information projections for the top model in a given discipline can be made. Also based on these data possible gender differences between the jumpers can be analyzed, in order to possibly establish model and numerical values for both male and female population of jumpers. The survey was conducted on a sample of male and female finalists of the World Athletics Championships in Berlin in 2009 with the aim of determining the difference in the kinematic parameters that are important in achieving the score success. The sample included 16 athletes (8 female and 8 male), who participated in the finals World Championship. Using T-test module were obtained the results which established statistically significant differences between male and female athletes in eight (72%) of the analyzed kinematic parameters in favor of male jumpers. The differences were identified in the following kinematic parameters: running speed on the section run (11-6m; T=8,347) and (6-1m, T=8,031), the speed of the second step (VLCT2SB, T=8,678), the first step (VLCT1SB, T=11,463) and the horizontal speed of the rebound (HoVLCT, T=4,627) to the level of significance (p<0,001).Also were identified differences in the parameters of the length of the third step (LNGT3SB, T=2,840), the first step (LNGT1SB, T=2,270) and vertical speed of the rebound (VoVLCT, T=2,246) to the level of significance (p<0,05). Kinematic parameters (28%) of the second step length (LNGT2SB), the duration of phase contact (CONTACT) and the angle of reflection (ANGLE) have not recorded statistically significant differences between male and female finalists, which amounts to 28%.

Anaerobic abilities is the dominant activity in submaximal and maximal intensity. Conditioned by the good functioning of the cardiovascular and respiratory systems, morphological status, metabolism, muscle structure, etc. The research has conducted with the aim of evaluating fatique index of students of the Faculty of Physical Education and Sports. The sample included a total of 50 male students from Eastern Sarajevo and Niksic (age 21±0,5years, the average weight 78,05±8,14kg). For the evaluation of fatique index of students applied to the Running Anaerobic Sprint Test  (RAST). The results showed values of anaerobic capacity of students who ''are expected'' for this population. Average index of fatigue was recorded with students (FI=8,00 watts/sec) and max.value about 17watts/sec  suggesting a weaker state of anaerobic capacity or lower tolerance to lactate, despite the fact that it is a physically active population
