Background and Study Aim. Tabata training is getting more and more popular these days. Based on interval training offers metabolic booster that causes major benefits for reducing body fat storage.  It is an interval training protocol which is a cardio workout for fat loss. The aim: this study was to examine the effects of a specific 16-week Tabata intervention program on body fat reduction in inactive healthy women. Material and Methods. A non-randomized controlled trial with 2x2 statistical design was provide in this study. The research was conducted on a sample of 49 women (aged 30 to 45) employed in the administrative sector, with more than 6h of sedentary tasks in their habitual working day. It included one experimental group–EG (Tabata program, n=24) and one control group–CG (without physical activities, n=25) and two moments of evaluation: (Initial) at baseline and (Final) after 16 weeks of post intervention period. The body composition parameters and body circumference in each group was recorded. All body composition parameters were measured using a Body composition analyser (Tanita BC-418MA III). Results. The results revealed that there was statistical significance difference after Tabata training program (TTP) in EG for body composition parameters (Mean±SD) for Body mass index (kg/m²) = 22.11±2.59kg/m²; p=0.04, ES=0.07); Fat tissue (%) =25.97±4.72; p=0.03, ES=0.08) and Fat tissue (kg) =17.52±5.11; p=0.02, ES=0.10). Furthermore, there were statistical significance difference in upper-arm circumference (24.95±2.31, p=0.00, ES=0.16) and waist circumference (75.93±7.18, p=0.02, ES=0.10). The control group did not achieve significant differences in the final measurement. Conclusions. Tabata training exercise program (4 months) has been shown to be beneficial for reducing body fat in healthy inactive women

Background and study aim. Group fitness programs are a form of programmed physical exercises with the aim of improving health, aesthetic appearance, satisfying the motivation to preserve health and reduce body weight. The aim of this study was to determine the effects of an experimental cardio fitness program on the morphological status of female subjects aged 21.5 ± 3.5 years. Material and methods. The experimental program was implemented over a period of three months (12 weeks), with a weekly frequency (3 x 20-60 min). Initial and final measurements were performed and Body weight, Body fat percentage, Body fat mass, Free fat mass, Body muscle mass, Body mass index and Basal metabolism rate were analyzed. All test subjects have their doctor's confirmation that they are healthy and can undergo training loads in a planned and clearly defined cardio program. Results. The exercise program on cardio equipment caused changes in all body composition parameters between the initial and final measurements t-test (except for muscle mass). The total average Body weight at the initial-final measurement (66.45 vs. 64.70kg; t= 5.225, p<0.000), which represents a difference of -1.75kg after the program. Conclusions. The assumption is that a controlled and monitored program with a special focus on nutrition would lead to even more precise results on the effects on body composition. Continuous application of the content of this program throughout the entire one-year macrocycle with a higher weekly frequency would certainly give even more significant results.

Serum levels of testosterone (ST) and high-density lipoprotein (HDL) are generally associated with atherosclerosis in male patients over 50 years with critic iliac stenosis (TASC II A and B) and cardiovascular disease with significant changes in HDL and low-density lipoprotein (LDL). In addition to the standard therapy, combined medicamentous therapy and adequate model of exercise are also important factors as medicines can improve HDL levels and primary bypass and endovascular potency impacting positively on improvement of ST or it can be the following testosterone replacement therapy (TRT) comprising cardiovascular disease prevention and vascular treatment as adjunct therapy options after endovascular and vascular surgical procedures. The aim of the study is to identify the association between HDL and ST after surgical and endovascular intervention on the iliac segment (TASCII A and B), as well as cardiovascular risk factors with modified medium activity (MET) <6 with short interval increase over >6 (MET), with total duration of 30–60 minutes. It also attempts to remodel a patient behavioral pattern, optimize ST levels and link them to outcomes and patency of vascular procedures on the iliac segment. Materials and methods. 108 selected male patients with cardiovascular disease combined with metabolic syndrome and critical iliac artery stenosis (TASC II A and B) were examined during 2014–2018, 4 years after invasive and minimal invasive treatment (54 patients were treated with surgical Dacron reconstruction and 54 patients – with endovascular treatment on short segment of critical iliac artery stenosis (TASC II A and B). Results. In the total population, no difference was observed in changes of constraint-induced movement therapy between the standard exercise group and the control one after 4 years from baseline. However, there was no significant interaction between the effect of exercise trainings and primary bypass potency within 4 years. Conclusions. Primary effects of endovascular procedure and Dacron bypass revascularization raise the risk of elevated testosterone levels after 4 years of group training but does not provide adequate answers to questions as to whether higher levels of ST have any major influence on primary bypass potency preventing further progression of cardiovascular disease and general symptomatic and asymptomatic atherosclerosis. However, exercise and TRT can be potential adjunctive therapeutic options for a future supporting postsurgical and endovascular illiac treatment in cardiovascular patients with low testosterone levels.

Purpose. To select recommendations on the use of physical culture means for students of future teachers, it is necessary to identify their functional features and genetically determined properties of the nervous system. Purpose: to reveal the relationship between the performance of the nervous system, orthostatic test and professional specialization of students of pedagogical universities. Material and methods. Students from 9 different faculties of Ukraine's leading pedagogical institute took part in the study. The total number of subjects was 841 people. Soon the reactions were determined by the program "Psychodiagnostics". Orthostatic reactions were determined by the results of heart rate in the supine position and in the standing position. An analysis of variance (ANOVA) was performed using Duncan's method to determine the influence of teaching faculty on test performance. A correlation analysis of testing indicators and ranks of faculties was carried out using the Tau-b Kendall method. Results. Students of all experimental faculties were divided into 4 groups according to the number of errors in the choice reaction test based on the results of variance analysis (Duncan method). Faculties were divided into ranks from the first to the fourth. A significant negative correlation of the rank of the faculty according to the indicator of the strength and speed of nervous processes with the heart rate in the standing position (p<0.05) and the difference between the heart rate in the standing and lying positions (p<0.01) was revealed. Conclusions. Physical exercises should be applied according to the professional characteristics and personal inclinations of the students, who were divided into 4 groups according to the indicators of reaction speed and orthostatic test. For students of the faculties of primary education and preschool education (1st group), we recommend using mobile and sports games. For students of humanities and natural sciences faculties (2nd group), any physical exercises that require an average manifestation of all physical qualities are suitable: dances, gymnastics, sports games, martial arts. Students of the Faculty of Arts (3rd group) are suitable for physical exercises that require high concentration of attention for a long time, for example, cyclical exercises. We recommend that students of the Faculty of Physical Education and Sports (4th group) continue to improve in their chosen sport, while also studying other sports.

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 fitness profile. Based on the detection, analysis and evaluation of these parameters, it is possible to define the fitness profile of the competitors as well as possible mutual differences. The current case study analyzes the fitness profile of competitors of three different disciplines (middle and long distances, cycling, ski 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) – ski biathlete, member SK "Romanija" Pale, and BIH national team. A total of 12 parameters were measured to assess the fitness profile (repetitive strength, explosive strength, speed and agility). The results recorded considerable homogeneity of the sample with mutual differences. In addition to mutual differences, all study participants are characterized by an extremely good fitness profile, as shown by the measurement results.  Article visualizations:

Background: Long jump are cyclic-acyclic movements of maximum intensity. It is a discipline that combines speed and jump in technique, that is, the speed-strength properties of competitors. Speed, agility and explosiveness are of special importance in jumpers. 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 Long jump. Material and methods: In study included 21 top male jumpers (BH=184.19±4.68cm; BW=78.86±6.81kg). Their achieved best results were analyzed. Pearson correlation coefficient was used to determine the relationship between body height and body weight and the results of long jumpers. 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: Simple regression analysis did not show a statistically significant effect of Body height on the results in the long jump (BH vs. Long jump R=0.183; p>0.05), while Body weight confirmed a significant inverse relationship with the results of the jump (BW vs. Long jump R= - 0.442; p<0.05). Conclusion: Long jumpers contain a large percentage of active muscle mass that integrates and generates motor explosive abilities for the success of long jumpers, primarily strength and speed, which is confirmed by the results of the study. However, a good jump technique is also necessary, but with optimal body weight, because any increase in weight has a negative effect on the length of the long jump.

The purpose of the study is to scientifically substantiate the positive influence of football on the physical and intellectual development of athletes. Material and methods. When conducting experimental research, a student questionnaire was first conducted to identify the success of studies and the specific interests of students who play football, play other sports, and students who do not play sports at all. 82 fifth-grade students of schools No. 38, 49 took part in the survey. The formative experiment was conducted on the basis of Kindergarten No. 38, in the fifth grades. It was found that the largest percentage of the total number of students are those engaged in other sports (58.5%). A large number are students who do not play any sports (34.10% of the total number of students). The smallest percentage was found among students who play football (7.3% of the total number of students). Results. It has been established that among the students who play football, there are absolutely no students who study at the first level of competence (in the final grades there are grades of 1-3 points on a 12-point scale), 33.3% are those whose academic success is level 2 competence (among the final grades there are grades of 4-6 points), and the largest percentage are students studying at the third level of competence (66.7%) (among the final grades there are no grades below 7 points). Among the students who are engaged in other sports, there are also absolutely no students who study at the first level of competence. Among students who do not play sports, the largest number of those who study are dissatisfied and satisfied. This shows that playing sports, both football and other sports, provide conditions for improving academic performance Conclusions. The obtained data indicate that the practice of sectional work on football provides conditions for the combined physical, intellectual and artistic development of children, about the possibility of a comprehensive all-round influence on the process of child development through the use of effective means of comprehensive development of children.

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.
