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.

The "EuroFit" program, which lasted one school year, was applied to a sample of eleven- and twelve-year-old boys. Motor tests were measured at the beginning and end of the school year. The motor tests that were monitored at the beginning and end of the school year related to; 'Flamingo' balance-FTR (test of general balance), Hand tapping-PLT (test of rapid hand movements), Reach while sitting-SAR (test of general flexibility), Long jump-SBJ (test of explosive strength of the lower extremities), Sit ups-SUP (abdominal muscle strength test), Arm pull-BAH (arm and shoulder girdle strength and endurance test) and body height-VIS were measured. The aim of the research was to determine the differences after the application of planned and programmed physical education classes using EuroFit program contents. After the implemented program and the measurements at the beginning and end of the school year, statistical data processing was performed. The results of descriptive and advanced statistics show exactly that there has been a positive transformation in the area of psycho-motor abilities of students. It is important to point out that the results at the end of the school year were better in all tests. At the general (overall) level, the transformation is positive and statistically significant. According to the obtained results, the hypothesis that reads "Positive transformations of motor skills are expected under the influence of the EuroFit program in the period of one school year" was confirmed.

In this research we attempted to define the procedure which could be used to provide optimally distinct groups of school children in terms of the morphological structure of their bodies, and which could further be used to define the possible differences in explosive and repetitive strength. With this aim in mind, a sample of 269 school children aged 12±6 months were included in a study where three of their morphological measures were taken (body height, body mass, skinfolds) and five motor tests for the evaluation of explosive and repetitive strength carried out. First the K-means cluster analyses were used to define three distinct groups of participants in each individual morphological segment, with low, average, and high values. On the basis of the maximal number of possible combinations of previously defined groups from the overall sample of school children, three groups with different morphological structures of the body were determined, including: 104 school children with low values, 113 school children with average values and 52 school children with high values for all three morphological measurements. These defined groups of school children were used to determine the possible differences in the tests of explosive and repetitive strength.On the basis of the obtained results we can conclude that the group with low values of morphological indicators (height, body mass, skinfolds) achieved the best results on the test for the evaluation of repetitive strength of the arms (MSKL), the group with average values on the tests for the evaluation of explosive strength (MSDM and MT20V), while for the rest of the tests there was no statistically significant difference between the distinct groups.The definition of the potential possibilities for the manifestation of certain motor skills, on the basis of these morphological indicators for each age category of school children, would be made possible through the application of a small number of anthropometric measures. The classification of a certain child into a suitable (appropriate for his affinities) group would enable the realization of a special work program which would enable the most effective improvement of his qualities

UvodPored mnogobrojnih faktora koji utiču na formiranje ličnosti djeteta, u novije vrijeme u sociološko-psihološkoj literaturi ističe se važnost ponašanja roditelja prema djeci kao značajnog faktora u razvoju ličnosti djeteta. Važno je razmotriti ponašanje roditelja prema djeci u periodu ranog djetinjstva te utvrditi kauzalnost s poremećajem u ponašanju u periodu adolescencije. Belsky 2 je prvi istakao kako je uticaj roditeljskog ponašanja na razvoj djeteta rezultat procesa u kojem učestvuju višestruke unutarporodične i vanporodične determinante. Samo roditeljsko ponašanje je kompleksno i nema jednostavnih odgovora na pitanja kako se ponašati prema djeci različite dobi u različitim situacijama.U dosadašnjim istraživanjima potvrđena je povezanost zasebnih dimenzija roditeljskog ponašanja s dječijim funkcionisanjem. Autor Pettit i saradnici 3 u longitudinalnoj studiji proučavali su uticaj bihevioralne i psihološke kontrole roditelja na pojavu problema u ponašanju.Ustanovili su kako psihološka kontrola koju sprovodi majka koja se ogleda u strogom načinu disciplinovanja djeteta utiče na razvoj eksternalizovanih problema (delinkventnoga ponašanja) naročito kod djevojčica u ranoj adolesecenciji, te na razvoj anksioznosti, depresivnosti i delinkventnoga ponašanja u kasnijoj adolescenciji. Nedostatak bihevioralne kontrole od strane roditelja povezan je s eksternalizovanim problemima poput: impulzivnosti, agresivnosti, delinkvencije i upotrebe opojnih sredstava 4 .
