The aim of this study was to examine whether additional training protocol of isokinetic training results in increased biomechanical values of certain parameters and whether it increases functional correlation between speed and strength leading to improved performance of acrobatic elements in floor exercises. Additional training protocol, which lasted for one semester, was performed on Biodex 3 apparatus (60°∙s–1). Examinees participating in this research were (N = 80) male students from Faculty of Sport and Education (mean age, 19.8 ± 1.7 year; weight, 75.2 ± 2,9 kg; height 179.7 ± 6.4 cm). Control group (N = 40), between two measurements, conducted only regular practical teaching program of artistic gymnastics. Experimental group (N = 40), besides regular practical teaching program of artistic gymnastics, also had additional program of isokinetic practice on Biodex 3 apparatus. Experimental group showed obvious structural changes that can be dominantly registered through variables assessing the maximum strength of the dynamic knee stabilizers (the maximum moment of force, overall work and average strength) and reciprocal relationship between agonist and antagonist muscles. In variables assessing the performance of elements of floor exercises in artistic gymnastics we obtained statistically significant differences in elements requiring changes of the maximum strength of the dynamic knee stabilizers: dive roll, back handspring, salto forward and backward tucked.

Predikcija uspjeha studenata Fakulteta za kriminalistiku, kriminologiju i sigurnosne studije pri odabiru najboljih kandidata za potrebe Ministarstva unutrasnjih poslova Kantona Sarajevo u cinu Mlađi inspektor, sprovedena je na ukupnom selekcionom uzorku od 166 ispitanika prve godine Fakulteta za kriminalistiku, kriminologiju i sigurnosne studije Univerziteta u Sarajevu. Ukupan uzorak je podijeljen na dva subuzorka koji cine studenti muskog pola (N = 85) i ženskog pola (N = 81). U ovom istraživanju prediktorski skup varijabli za procjenu uspjesnosti u mogucoj selekciji studenata Fakulteta za kriminalistiku, kriminologiiju i sigurnosne studije za cin Mlađi inspektor u Ministarstvu unutrasnjih poslova Kantona Sarajevo, predstavlja skupina od pet (5) izolovanih latentnih motorickih dimenzija, koje su veoma bitne pri selekciji i odabiru kadrova za potrebe Ministarstva unutrasnjih poslova, u cinu Mlađi inspektor. Uzorak kriterijskih varijabli cini ukupno pet motorickih testova, koji koristi Ministarstvo unutrasnjih poslova Kantona Sarajevo za selekciju ljudskih resursa i potencijala u cinu Mlađi inspektor.

This research was conducted with the aim of determining the effects of the sports elements of the military training on qualitative changes of morphological characteristics, in soldiers - conscripts of the Armed Forces, and which is not only designed to achieve scientific results that would be academically defended, but also it should represent a way of controlling the results achieved by applying the scientific methods, critical reviewing and correcting any noticed weaknesses. The population from which the sample was derived were soldiers-conscripts who were on a quarterly training at the training centre in Pazaric. The total sample consisted of 435 conscripts-soldiers (men) from all over Bosnia and Herzegovina, aged 19-26 years. The variables chosen for this scientific work hypothetically covered spaces of morphological characteristics (10), and included spaces: longitudinal dimensionality of the skeleton, subcutaneous fat and circular dimensionality of the skeleton and body mass in soldiers conscripts who were on a quarterly training in training centre for basic training in Pazaric. The gained results of the factor analysis in the area of morphological characteristics show that the two main components (factors) were isolated (extracted) on the initial and final measurements, which tells us that the Plan and the program of physical training, greatly contributed to the qualitative transformation of morphological characteristics with conscripts of Armed Forces conditioned by sports content of military training for a period of three months.

Original scientific paper This paper aims to present the investigation of the influence of the physical and health education at the transformation of basic motor abilities of students fifth graders, using various methodical organizational work in teaching physical and health education in the course of one school year. The aim of this study was to determine possible differences in the basic motor abilities between differently treated groups of examinees consisting of 198 boys and girls attending the fifth grade of primary school (age 10-11 years). The sample was divided into two subgroups, control and experimental group (N = 99). Teaching model that was implemented by the control group was performed by the current curriculum with two hours per week of regular classes of physical and health education, with a variety of programs in athletics, gymnastics and sports games, but with the use of simple group methodical organizational forms of work. Teaching model that was implemented by the experimental group was performed by the same curriculum as the control group with the same contents, but with the use of more complex organizational forms. Based upon analysis of the data obtained, using the T test, and canonical discriminant analysis, we have obtained significant differences of the results of basic motor abilities among students in the experimental and control group, and that these differences are in favor of the students in the experimental group, and that these students have significantly higher levels of applied basic motor skills compared to students in the control group.

The aim of this study was to investigate the relationship and effect between mechanical output in maximum vertical and horizontal jumping students 3 year of Faculty of PE and Sport, University of Tuzla, on the sample consisted of female (n=30) and male students (N=37). Sample of dependent variables were drop jumps from 20, 40, 60, 80, 100cm. A sample of independent variables included only one variable bunny jump: all data were analyzed using Tanita TBF-300A, Optojump, Brower Timing System and SPSS 17.0. Regression analysis explained (R Square) 34% of the common variables criteria. Analyzing the effect of individual variables, statistically significant effect on criterion variable was determined only to a variable drop jump from 80 cm (Beta: 0.611 ; p<0, 05).
