Endurance-type disciplines (running, cycling, biathlon) define the cyclic structure of an athlete's movements, which, in addition to functional parameters, also includes an adequate morphological profile and body composition. Based on the detection, analysis and evaluation of these parameters, it is possible to define the body composition of the competitors as well as possible mutual differences even though it is endurance sports. The results are all the more relevant if the profile of top athletes with notable results is being evaluated. The current case study analyzes the morphological dimensions and body composition of competitors of three different disciplines (middle and long distances, cycling, biathlon) of top-level competitors, members of national teams. The study was conducted: Uroš Gutić (UG) - runner middle and long distances, member of AK "Sarajevo" and the BIH athletic national team; Milan Milivojević (MM) – cyclist, member of Cycling club "Borac" Čačak (Serbia), and the member Serbian national team; Stefan Lopatić (SL) – biathlete, member SK "Romanija" Pale, and BIH national team.

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.

The study included a sample of 48 male and female Olympic finalists (Beijing, 2008; London, 2012; Rio de Janeiro, 2016) in the long jump discipline. The following primary parameters of anthropological status (Body height, Body mass, Body Mass Index, Age) and Result (secondary parameter) were analyzed. The aim of the study was to determine the differences in the defined parameters of anthropological status (body height, body weight, BMI, and age) between male and female long jump finalists. The basic central and dispersion indicators were calculated on the basis of which a descriptive comparison of the analyzed variables was performed. The significance of the difference between subjects was examined by MANOVA and ANOVA (p

Public health of people and individuals is the most important resource in the modern world. The sugar epidemic and cardiovascular diseases are linked to the obesity epidemic. As obesity appears at younger and younger ages, it is to be expected that the proportion of people who have been obese for the number of years will increase and that those practicing a "sedentary lifestyle" will move less and less. Diabetes mellitus type 2 (DMT2) and cardiovascular diseases (CD) are among the top ten causes of death in the world. It is observed that the association between DMT2 and CD risk is not the same for both sexes, with the cardiovascular risk associated with DMT2 being greater in women. Among the different strategies for the prevention and treatment of DMT2 and risk factors for CD, physical exercise has been largely recommended because of its positive effects on glycemic control, body mass, blood pressure, and lipid profile. A higher level of daily physical activity significantly reduces the risk of contracting numerous diseases such as: diabetes, diseases of the heart and blood vessels, certain forms of malignant diseases, obesity, asthma, osteoporosis and others.  Article visualizations:

Background: Morphological dimensions represent the functioning of the growth and development of the musculoskeletal system and also play a role in specific volleyball activities. In the sphere of volleyball, it is imperative to identify the anthropometric constitution, generated by exogenous and endogenous factors. Aim study : The main goal of the research was to determine the factor structure of isolated latent dimensions of the population of female volleyball players of VC "Jahorina" Pale, a member of the volleyball Premier League of Bosnia and Herzegovina. Methods: The study involved 18 active players of the women's volleyball club Jahorina (BH=173±8.77cm; BW=66.04±9.09kg; BMI=22.03±2.19kg/m2, age=19.11±2.63 years old) members of the volleyball Premier League of Bosnia and Herzegovina. A set of 15 anthropometric variables was measured in the morphological space with the aim of determining correlations between anthropometric characteristics and identifying the latent morphological structure of volleyball players. Result: Statistical processing of the data was performed by Pearson correlation coefficients and Hoteling principal components analysis (PCA). The results of the correlation analysis showed statistically significant linear correlations between most anthropometric variables (p<0.05; p<0.01; p<0.001). The three-component model, which defined 81.45% of the proportion of the total common variance of the manifest anthropometric variables, was extracted by the method of analysis of the main components, with the Gutman-Kaiser criterion and Varimax rotation. Conclusion : It was structured by hypothetical factors with characteristic roots (Eig.>1), which were interpreted as Factor of volume and longitudinal dimensionality of the skeleton (F1=42.45%; Eig. 6.37>1), Factor of skin folds of the trunk (F2=28. 96; Eig. 4.08>1) and Subcutaneous adipose tissue factor of the lower extremities (F3=10.04; Eig.2.12>1). The correlation of the factors confirmed the inverse relationship of the factors (F1-F2=-0.85; F1-F3=-0.81). It can be concluded that the increased volume of volleyball players is not accompanied by higher values of skin folds, but is a consequence of increased muscle mass.

By using various sports recreation programs, we try to reduce the negative effects of living in today's age. This study defines a sports-recreational program based on athletic throwing exercises. The reduced amount of muscle mass that comes with age and thus the deficit of strength, coordination and balance cause difficulty in movement and the inability to perform harmonious movements. The decline in motor skills that comes at the time of involution can be quite slowed down through recreational programs that target these abilities. Considering that sports recreation is in question, the intensity and scope of action is logically significantly less than competitive training. In addition to the basic disciplines of shot put, discus throw, javelin throw, and hammer throw, the recreational program also used a large number of exercises that throwers use in their training as ancillary exercises as well as exercises with free weights. The aim of this paper is to emphasize the importance of recreational exercise and health and the wider sports and recreational content of athletic throwing.

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.

Purpose: Young people who study physical education and sport are a priori regarded as having proper body structure and body composition. It is widely presumed that young who study physical education at one of several national universities of physical education (East Sarajevo) could be characterized with proper physique and body composition. Aim of the current study was to assess and analyze the body composition of a male students Physical Education and Sport, University East Sarajevo, by bioelectric impedance analysis and determine the significance of inter correlation coefficients. Material and methods: In study the participants consist 30 male students of Faculty of Physical Education and Sport, University of East Sarajevo, the III year of study (Body Height = 182.20 ± 6.89cm; Body Weight = 80.06 ± 8.80kg; Body Mass Index= 24.03 ± 2.58kg/m²). Results: of the study showed that the body composition is within the healthy (allowed) values recommended for this population of students (Body Fat=10.90kg or 13.62%; Body Muscle= 65.74kg or 82.40%; Body Water = 61.54%; Basal metabolic rate = 2045.07kCal; Daily calorie intake = 8436.56 kCal, etc.). Inter correlation coefficients showed inverse and significantly high correlation (p=0.000) between (inter correlation coefficient Fat-Muscle = -0.945), (inter correlation coefficients Fat-Water = -0.963) while direct correlation was achieved between (inter correlation coefficient Muscle-Water = 0.986). Conclusion: The obtained results of the study defined the appropriate body composition of the students, which is a consequence of their adequate physical activity and well-designed curricula at the home faculty. In the parameters of body composition, students of physical education and sports in East Sarajevo had a higher muscle component and lower values ​​of fat component than other students as a result of their somatotype, way of studying, teaching and extracurricular physical activities.

The purpose of this study was to determine the differences in anthropometric characteristics between sprinters and jumpers to aim education more accurately in these fields. The study included 24 men in athletics, they were divided into two groups: 14 sprinters (age 21.57 ± 1.16 years) and 10 jumpers (21.80 ± 1.03 years). The variables included 13 anthropometric measures. To determine the differences between groups of variables it was used Mann-Whitney U test and analysis of variance (ANOVA). The results of the Mann-Whitney U test showed statistically significant difference (p ≤ 0.05) in two variables for estimating subcutaneous adipose tissue, chest skinfold, and midaxillary skinfold. Other analyzed variables for assessing the longitudinal of the skeleton, and body mass and volume differences were not statistically significant (p ≥ 0.05). These findings may give coaches better knowledge, suggest following recent methods and be more careful in training programs with different athletics.

Purpose: In today's sport, and especially in high-performance sports where volleyball also belongs, continuous monitoring of Body Composition (BC) can significantly regulate the training process, which has a positive effect on the top form of athletes. Aim of the current study was to assess and analyze the body composition of a female volleyball players VC "Jahorina", by Bioelectric Impedance Analysis (BIA). Material and methods: In study the participants consist 18 female volleyball players, the members of the  Volleyball Club ''Jahorina'' from Pale, East Sarajevo City (Body height = 173 ± 8.77 cm; Body weight = 66.04 ± 9.09kg; BMI = 22.03 ± 2.19 kg/m², decimal age 19.11 ± 2.63 years old) who competes in the Premier League of Bosnia and Herzegovina (B&H). Results: of the study showed that the body composition is within the healthy (allowed) values recommended for this population of volleyball players (Body Fat = 24.82%; Body Fat=11.44kg; Body Water = 53.68%; Body Muscle = 47.09 kg, BMR = 1538.08; DCI = 6435.38, etc.). Conclusion: Compared to the results of other authors, that Jahorina volleyball players do not lag far behind European clubs in terms of weaker BC (BF%, BFkg, BW%, BMkg, BMR, DCI, BMI, etc.). The only place where they are inferior is the body height of the volleyball player (height = 173 ± 8.77 cm), while the relative value of Body weight = 66.04 ± 9.09 kg is evident.

Cycling is one of the most demanding sports in terms of aerobic ability. Individual profiling, selection of cyclists implies adequate analysis of anthropometric characteristics and body composition. In addition to the analysis of anthropometric characteristics and body composition, it is necessary to detect and assess motor (physical) abilities, which are often defined by the term fitness profile. In this study, the anthropometric space, body composition and fitness abilities of cyclist M.M, a member of the Cycling Club "Borac" from Čačak and a member of the Serbian national team were analyzed in detail. As many as 60 variants were measured to assess the defined segments (anthropometric space, body composition, fitness profile). The obtained results of anthropometry and physical status confirmed the presence of the ectomorphic-mesomorphic somatotype of the cyclist, which is represented in the so-called road disciplines and endurance disciplines. Also, the fitness profile of the competitor determines extremely good results in all motor skills. To conclude that in addition to the dominance of aerobic abilities, cyclists define exceptional parameters of anaerobic abilities and fitness (motor) abilities (strength, speed, coordination, ...) and their pronounced synergistic effect.  Article visualizations:
