Osnovni cilj ovog istraživanja bio je utjecaj pojedinih motorickih sposobnosti na natjecateljsku uspjesnost stolnotenisaca. Uzorak ispitanika cinilo je 48 najboljih seniora uzrasta 17-36 god (reprezentativni uzorak) u Bosni i Hercegovini. Uzorak ispitanika je odabran na osnovu kvalifikacionog turnira svih registriranih stolnotenisaca Bosne i Hercegovine. Mjerni instrumenti za ovo istraživanje su: dvanaest varijabli za procjenu bazicnih motorickih sposobnosti i jedna varijabla za procjenu natjecateljske uspjesnosti u stolnom tenisu. Metode obrade rezultata ukljucivale su deskriptivne statisticke procedurei multiplu regresijsku analizu. Motoricki prediktori primjenommultiple regresijske analize znacajno su objasnili kriterijsku varijablu natjecateljska uspjesnost stolnotenisaca.Na osnovu rezultata multiple regresijske analize koja je sprovedena na sest neovisnih, prediktorskih varijabli iz skupa bazicne motoricke sposobnosti i pozicije ispitanika na rang ljestvici stolnotenisaca (BODRNG), kao i ovisnom varijablom natjecateljske uspjesnosti, uz koristenje enter metode, dobivena je jedna statisticki znacajna regresijska funkcija. To ukazuje na to da između navedenih varijabli postoji linearna povezanost. Dobiveni koeficijent multiple korelacije je statisticki znacajan i iznosi R=.65, sto govori da se oko 41% varijance rezultata varijable pozicija ispitanika na rang ljestvici stolnotenisaca (BODRNG), može objasniti uz pomoc ukljucenih prediktorskih varijabli. Kao ukupno gledano najznacajniji prediktor može se izdvojiti varijabla tapinga rukom, to jest varijabla za procjenu frekvencije pokreta. Međutim, ne treba zanemariti i varijable za procjenu eksplozivne snage i to kako onih za procjenu apsolutne, tako i procjenu relativne eksplozivne snage.

Original scientific paper The research was conducted on a sample of 170 female students at the age of 14-16 years, from the elementary school. According to the research criteria, answering the question of the requirement for engaging in sports, the sample was divided on two subsamples, and with this research 170 girls were tested, from which 70 were defined as female students who regularly attend classes of physical education and are dealing with volleyball and 100 were defined as female students who regularly attend classes of physical education but are not dealing with any sport. The main goal of this research is partially establishing the quantitative and structural differences in basic-motor abilities of female students at the age of 14-16 years dealing with sports (volleyball) and non athletes. For the determination of the partial quantitate differences on uni variant level between the two subsamples t-test for small independent samples was applied. Based on the results of Wilk's Lambda, and in association with Rao’s approximation, are giving a significant difference Q = .00 (plevel = 0.00) of the analyzed space. From the analysis of the results it can be concluded that there are differences between groups in the examined space. By applying the uni variant analysis of variance (ANOVA), can be seen statistically significant difference between respondents in the two groups of respondents in the variables: From the results of the ttest, it can be concluded that the analyzed group of respondents statistically significant differs in the variables.

The study was conducted on a sample of 92 participants at the age of 13-15, who were in the training process at least a year. The sample of participants is composed of two groups of judo athletes, 50 from Macedonia and 42 from Bosnia and Herzegovina. The aim of this study was to compare the anthropological dimensions between these two groups of participants. For the purposes of this study 28 variables were used: 9 variables for anthropometrical measures, 14 variables for motor dimensions and 5 variables for assessing situational movement structures of judo athletes. The univariate and multivariate statistical methods were identical in some anthropometrical measures, in particular the motor skills and situational movement structures of judo athletes, between groups.

This research was conducted on a sample of seventy-two boys who were eleven and twelve years old and who were members of volleyball school. The aim of this research is to establish the partial quantity differences in transformation of motoric and situationalmotoric abillities of volleyball school member boys between initial and final measurment under the influence of programmed volleyball practice.Fifteen basicmotoric variables and five variables for assesment of situational-motoric abillities of volleyball players were used in this research. With the use of Ttest for dependable causes, it was established that programmed volleyball practice has produced statistically important partial transmittion effects in the area of motoric and situational-motoric abillities of the participants between the initial and the final measurement.

Modern soil tillage systems based on different tools than mouldboard plough have very often stronger weed occurrence, which can be a serious problem for achieving high yields. An obvious solution for weed suppression is a herbicide, whose improper use can deteriorate environment and lead toward serious ecological problems. In order to investigate the interaction between soil tillage and herbicide, trial was set up in Valpovo in seasons 2008/09 - 2010/11. Two soil tillage systems (CT-conventional tillage, based on mouldboard ploughing, and CH-chiselling and disk harrowing, without ploughing) and five herbicide treatments (NH-control, no herbicides; H10- recommended dose of Herbaflex (2 l ha-1); H05-half dose of Herbaflex; F10- recommended dose of Fox (1.5 l ha-1); and F05-half dose of Fox) were applied to winter wheat crops. Results showed similar effects of soil tillage on the winter wheat yield, whereas different herbicide dosages showed similar weed suppression and influence on winter wheat yield.

The results of a poll were stated for 220 students (school year 1987/88):parents' education, marks in secondary school, living conditions (54.6% lives with their parents), on whose expense they live (87.6% are supported by the parents), and how they spend their time (3-5 hours for household duties and learning, 5-8 hours for classes).
