    ANALYSIS OF THE MORPHOLOGICAL STATUS STUDENTS BY APPLYING OF DIFFERENT METHODS OF THE INDEX
    (Faculty of Education – University of Travnik, Bosnia & Herzegovina, 2015) Pavlović, Ratko; Raković, Aleksandar; Mihajlović, Ilona; Petrović, Borko; Stanković, Daniel
    Nowadays it is generally lived in conditions of rapid pace, poor quality and unhealthy nutrition, reduced or insufficient movement, in a word hypokinetic lifestyle. Consequences of hypokinesia are many, and refer mainly to diseases of the cardiovascular system, the respiratory system, and the occurrence of diabetes. In addition, it can also be stated and the uneven growth and development of the individual leading to the negative trend of the development of some anthropometric characteristics and also to the morphological status of the individual. This research is dealing with the analysis of students of Physical Education and Sports. For the estimation of the morphological space was applied: Lorentz constitutional index (LKI), Muscle index (MI%), Body Mass Index (BMI kg/m²). The results showed that it is to low but positive a tendency of the stronger development of bone and muscle tissues of students, where the mean value of LKI is (Mean=1,50), muscle index MI (Mean=10,64%), that is they are in the upper limit of the middle development musculature. The average BMI values of students (Mean=23,60kg/m²) is also an indicator that this population increases the value defined by BMI, whose value is in the upper limit of normal body weight. These values BMI fully correspond to the values that were realized in the LKI and MI.

    Anthropometric parameters of elite male runners sprint: are body height and body weight good predictors of results
    (H.S. Skovoroda Kharkiv National Pedagogical University, 2022) Pavlović, Ratko; Mihajlović, Ilona; Radulović, Nikola; Nikolić, Siniša
    Purpose. Athletic sprint runs are cyclical movements of maximum intensity. Speed, reaction time, agility and explosiveness are of special importance in sprinters. The main goal of the research is to determine the influence of Body height (BH) and Body weight (BW) with the best achieved results of in sprint disciplines (60m,100m,200m). Material and methods. In study included 40 competitors, top male sprinters (BH=180,45±6,88cm; BW=78,83±7,69kg). Their achieved best results in sprint disciplines were analyzed (60m, 100m, 200m). Pearson correlation coefficient was used to determine the relationship between body height and body weight and the results of sprint disciplines. Also a univariate model of regression analysis was applied and the relevant coefficients were calculated. The level of acceptance of statistical significance was set to p<0.05. Results. The simple regression analysis did not show a statistically significant influence of body height and body weight on the result of sprint running. Low correlations (BH vs. 100m = -0.306), (BW vs. 100m = -0.226) and (BH vs. 200m = -0.221) and insignificant correlations with an inverse relationship between results and anthropometric measures are mainly evident. Conclusion. Body height and body weight did not have a statistically significant effect on the results of the 60m sprint, while their influence is evident in the 100m, and especially in the 200m (but without statistical significance). This influence on the result of running 100 and 200m is a consequence of the exceptional motor-functional abilities of the sprinter to show greater force in the last phase of the rebound. Otherwise in the sprint, the rear rebound phase is much more important than the front rebound phase. A long step with the body weight (muscle) of the sprinter produces a higher rebound force, which with a big frequency of steps and good tecnique guarantees a good result.

    EVALUATION OF ANAEROBIC ABILITIES OF PHYSICAL EDUCATION AND SPORTS STUDENTS APPLYING THE RUNNING ANAEROBIC SPRINT TEST
    (University of Travnik, 2015) Pavlović, Ratko; Mihajlović, Ilona; Radulović, Nikola
    Anaerobic abilities participate in most activities that are characterized by high intensity and short duration of activity. This type of endurance is the dominant activity in submaximal and maximal intensity. Conditioned by the good functioning of the cardiovascular and respiratory systems, morphological status, metabolism, muscle structure, etc. The research has conducted with the aim of evaluating anaerobic abilities of students of the Faculty of Physical Education and Sport of East Sarajevo and Novi Sad applying Running Anaerobic Sprint Test (RAST). The sample included a total of 40 male students, including 20 students from Eastern Sarajevo (age 21±0,5 years, average weight 76,69 ± 6,61kg) and (20 students from Novi Sad (age 20±0,5 years, the average weight 76,75±9,49kg). The results showed almost identical values of anaerobic capacity of students who are expected for this population with little benefits students of East Sarajevo. The average strength of the lower extremities student East Sarajevo amounted to 594,79 W, compared to the students of the Novi Sad 574,12 W, which is a slight difference that is not statistically significant. A slightly higher average index of fatigue was recorded with students of Novi Sad from 8,45 suggesting a weaker state of anaerobic capacity in relation to the pattern of East Sarajevo, or lower tolerance to lactate.

    The effects of experimental program on the explosive strength of lower limbs in male adolescents
    (2022) Radulović, Nikola; Vukadinović-Jurišić, Mila; Pavlović, Ratko; Obradović, Jelena; Mihajlović, Ilona
    Background and Study Aim Various experimental programs for the development of motor skills are present in sports activities. Explosive strength can be defined as the ability to produce maximum force as soon as possible, and it represents an essential factor in activities where it is necessary to increase the acceleration of the body mass, the mass of specific body parts, or of an external object. The aim of study – to determine the effects of an experimental program on the explosive strength of lower limbs in male adolescents. Material and Methods One hundred and one male adolescent (aged 19 years ± 6 months; body height 181.43 ± 7.42 cm; body mass 80.08 ± 10.07 kg) were recruited and randomly divided into two groups: experimental group (E; N=48) and control group (K; N=48). The E group performed the experimental program which lasted fifteen weeks and consisted of three 60-min training sessions per week. All participants were tested on Squat Jump (SJ), Countermovement Jump (CMJ), Countermovement Jump with arms (CMJa) and Continuous Jump with Straight Legs (CJSL). The four tests were performed using a Kistler force platform to measure Quatro Jump Bosco Protocol Version 1.0.9.2 and gave us data about the jump height, number of jumps for 15s, average power jump and peak power jump. The multivariate analysis covariance (MANCOVA) and follow up analysis covariance (ANCOVA) were used to analyze the data. Results The results of MANCOVA showed statistically significant differences (p ≤ 0.001) between the E and K groups in all systems of variable lower limb explosive strength in male adolescents. In addition, results of ANCOVA showed statistically significant differences (p ≤ 0.001) in SJ, CMJ, CMJa and CJSL in favor of the E group compared to the K one. Conclusions The results of this research show that a fifteen-week experimental program can lead to significant improvements in lower limb explosive strength in male adolescents
