Simović S, Matković B, Mijanović M, Kocić M, Vojvodić M. Structure of efficiency factor at XIII, XIV, XV, and XVI World Championship in basketball. J. Hum. Sport Exerc. Vol. 7, No. 2, pp. 527-543, 2012. Applying the method of main components by Hotelling and the method of rotation of the main components, i.e. Varimax rotations by Keiser, the latent structure of basketball efficiency was established. It was based on the fourteen manifest indicators of efficiency. Our findings refer to the sample comprised of the game-winning teams at the World Championships: in Greece, 62 basketball teams; the USA, 62 basketball teams; Japan, 80 basketball teams; and Turkey, 80 basketball teams. Factorization was performed on the entire sample of all game-winning teams, that is 284, as well as on the single game winners at the championships in Greece, USA, Japan, and Turkey. There was the total of four factor analyses and within each of them five to seven latent dimensions, i.e. factors based on the fourteen manifest efficiency parameters were extracted. Katell method of landslide indicates a clear elbow between the third and fourth component. These first three latent dimensions in all four factor analysis exhibit the stability of factors and high saturation on the side of the manifest variables. The factors have been defined as: general offensive efficiency factor, three-points shot factor and free throw factor. Having the variables that account for the total number of attempted and made shots dominant within the structure of these factors, it can be concluded that general latent structure of basketball efficiency is indeed explained by means of shot efficiency. These findings confirm both empirical and theoretical speculations of basketball experts, i.e. the overall basketball efficiency is primarily dependent on the shot efficiency, what seems entirely logical.
Research papers investigating the game-related parameters and phenomena of women's basketball matches are relatively smaller in size and number than similar ones treating the same issues in men's basketball -although, there have been some changes in that respect in recent years. This paper includes a sample of 40 games and thirteen variables of standard efficiency recorded at FIBA EuroBasket Women 2017. The research had two basic models of regressions formed, i.e. an absolute and a relative one, each of which had total numbers scored as the dependent variable, and was performed by means of a regression and correlation analysis -a stepwise regression, as a gradual method of fitting regression models in order to define the predictive variables. The obtained regression models and partial correlation indicate that the winning or losing performance was heavily influenced by both field goal efficiency and defensive rebounding, all of which has been corroborated in many other similar research. Also, variables such as turnovers and personal fouls were extracted as significant in terms of the differentiation between the winning and losing team. When we take a closer look and see the observed parameters from the point of view of either First or Final rounds of the competition -since these rounds were played in different formats -it is noticeable that the difference is becoming more and more evident, of course besides shot efficiency, the efficiency of free throws and the quality of defense.
The aim of this study was to determine the impact of motor abilities on mastering an obstacle course and define quantitative differences in basic motor abilities between the students awarded poor grades and the students awarded higher grades based on the result achieved on the obstacle course designed to test motor skills. The results of regression analysis demonstrated that motor abilities are important for mastering an obstacle course for testing motor skills and, on the basis of them, we may predict the result that defines the students' specific skills. Moreover, the results of the Student's t-test for independent samples demonstrated a statistically significant difference in the level of motor abilities between the students awarded poor grades and those awarded higher grades. The difference is defined by statistically significantly better values of the results achieved on motor tests: the maximum number of sit-ups (MPTP), stick mobility (MOKP), hand tapping (MTAP) and Cooper's 12 minute run test (MKUP), achieved by the students with higher grades, based on which we can assume that these variables are predictive of successful mastery of the obstacle course for testing motor skills. The results obtained might contribute to a better organization of training work in teaching, especially regarding an approach to improving motor abilities that dominantly have an impact on mastering an obstacle course designed to test motor skills.
SUMMARYFor the investigation of interpersonal relations in small groups such as sports, sociometric procedure are used. In this study, sociometric procedure is conducted and sociometric structure has been made for the female University Volleyball Club BL volley from Banja Luka, who competes in the Premier League BiH. The task was to discover the emotional-social and functional status of the players, and the status of congruency and to evaluate the atmosphere at the club. Further analysis has been done of the aspirations of the players in terms of taking a position at the score table, as well as their assessment of management's expectations regarding the position on the score table. After sociogram and sociometric matrices has been made, it can be said that the team has three distinctive groups that are separated by mutual election of its members when it comes to emotional and sociological status. The assessment of functional status identifies two players who received 16 and 14 votes out of 17 possible. Two players who have received the most votes by socio-emotional criteria, were not selected in the first team by the coplayers, which again speaks of a team that very well makes a distinction between "friendship and business". Based on these results, it can be concluded that the atmosphere in the team is good and that it is not affected by functional status, or age of the players (almost half of the team is younger than 18). And finally, using Man-Vitni and Kruskal-Volis test it was found that neither age nor functional status does not affect significantly the assessment of the position on the score table. Functional status and age is also not a source of significant differences in the assessment of the players on what they think the club management is expected from them.
