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.

Poor dietary habits have become one of the most important concerns among public health policy makers in recent years, due to the impact they have on both economic and health systems of a country. The transitional period toward young adulthood, marked with high school graduation and the beginning of college years, has been identified as critical in terms of its influence on young people’s bad eating habits. The aim of this study was to assess whether the results obtained through Food Frequency Questionnaire significantly correlate with standard body parameters. Participants included 210 students from the University of Banja Luka, with the mean age of 21.94 ± 2.73 years. Factorization of Food Frequency Questionnaire Instrument extracted seven factors which were subjected to multiple regression analysis as independent variables, and correlated to dependent variables - anthropological measurements. This study shows that the factors labeled as consumption of bread, consumption of healthy food, and intake of carbohydrates, are significantly related to Body Fat Percentage, whereas factors labeled as intake of food of animal origin, and intake of fruits and vegetables, are statistically significant in terms of their relation to Waist-to-Hip Ratio. Only one factor, labeled as intake of unhealthy food, is significantly related to Body Mass Index; this is to suggest that Body Mass Index has again showed many limitations with regard to its research relevance. This research has also found that students of the University of Banja Luka typically consume white bread, known to have a direct link with overweight and obesity.

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.

Evaluation in women's basketball is keeping up with developments in evaluation in men's basketball, and although the number of studies in women's basketball has seen a positive trend in the past decade, it is still at a low level. This paper observed 38 games and sixteen variables of standard efficiency during the FIBA EuroBasket Women 2019. Two regression models were obtained, a set of relative percentage and relative rating variables, which are used in the NBA league, where the dependent variable was the number of points scored. The obtained results show that in the first model, the difference between winning and losing teams was made by three variables: true shooting percentage, turnover percentage of inefficiency and efficiency percentage of defensive rebounds, which explain 97.3%, while for the second model, the distinguishing variables was offensive efficiency, explaining for 96.1% of the observed phenomenon. There is a continuity of the obtained results with the previous championship, played in 2017. Of all the technical elements of basketball, it is still the shots made, assists and defensive rebounds that have the most significant impact on the final score in European women's basketball. It can be noted that, unlike with the previous championship, inside play is no longer dominant, but there is a balance between inside and outside play, which has already been established as a developing trend in men's basketball. The emergence of the offensive efficiency variable indicates that it is becoming significant in top-tier competitions as well but is still a challenge for coaches to grasp the causes of this multicomplex issue based on this indicator.
