The aim of this study was to evaluate the strength of the left and right hamstring and the quadriceps muscle group in professional handball players. It also aimed to assess the statistical significance of the relationship between these two muscle groups. The study included eight professional handball players from the "Borac" team, Banja Luka. Standard anthropometric measurements were taken. The following variables were assessed: maximum quadriceps torque (MQT), maximum hamstring torque (MHT), and hamstring–quadriceps ratio (HQR), to determine the presence of muscle imbalances bilaterally and unilaterally. Isokinetic testing of knee strength was performed on both knees at the Institute for Sports, Faculty of Physical Education and Sports, University of Banja Luka, using the CON-TREX CYK device, which allows comprehensive assessment of muscle and joint function. Based on the findings, there was no significant muscle imbalance in handball players, i.e., no significant difference in quadriceps or hamstring strength between the left and right legs, either bilaterally or unilaterally (p > 0.05). The strength of the left and right quadriceps and hamstrings showed minimal variation, with no evidence of muscle imbalance. In professional and elite sports, information from isokinetic diagnostics is essential for designing training programs and preventing injuries. This study provides normative data for the handball player population.

Background: Football is a sport that requires a high level of technical, tactical, and motor skills, with particular emphasis on agility, speed, explosive strength, and flexibility. The development of these abilities depends on biological maturity, training experience, and individual factors, which affect player performance across different age categories. Purpose: The aim was to examine and compare the level of motor abilities between football players of FC GOŠK Gabela (Premier League of Bosnia and Herzegovina) in the junior (U19) and senior (U25) age categories, focusing on key elements such as agility, speed, explosive and repetitive strength, as well as flexibility. Method: The sample consisted of 22 players from the same club, divided into two groups by age category: 11 juniors (U19) (body height = 181.56 ± 5.74 cm; body weight = 73.29 ± 6.40 kg; BMI = 22.21 kg/m²) and 11 seniors (U25) (body height = 184.98 ± 5.97 cm; body weight = 77.35 ± 5.70 kg; BMI = 22.55 ± 0.38 kg/m²). Descriptive statistics were used to analyze the data, and differences between groups were determined using an independent t-test for small samples. Statistical significance was set at p < 0.05. Mean Difference and 95% Confidence Intervals were also calculated to further assess the significance and effect size of the detected differences (Cohen’s d). Results: Seniors achieved significantly better results in agility tests (Illinois and Zig-Zag tests) and the 60-meter sprint, while differences in other tests were statistically insignificant (p > 0.05). Differences in upper body explosive strength (medicine ball throw) and flexibility were not significant, although seniors showed slightly better average values. Conclusion: The obtained results indicate that biological maturity and longer training experience significantly influence the improvement of motor abilities, especially agility and speed over longer distances.

Background and purpose Fatigue is a physiological phenomenon that reduces the ability of muscles to maintain maximal force during repeated activities. Anaerobic capacity and the Fatigue Index (FI) are key indicators of the body’s ability to sustain explosive power, and the Running Anaerobic Sprint Test (RAST) is a recognized tool for their assessment. Purpose: this study was to assess the anaerobic abilities of active sportsmen, using the RAST, with a focus on Peak Power (PP) and the Fatigue Index (FI). Material and methods The study included two male active sportsmen. (U.G., 70 kg and A.V., 85 kg) who performed six 35-meter sprints with 10 seconds of rest between sprints. Sprint time and lower limb power (W) were measured, while FI was calculated based on the difference between maximal and minimal power. Results Both participants showed a linear decline in speed and power during repeated sprints. A.V. achieved a higher level of power and a lower FI (11.6%) compared to U.G. (18 %). Power decreased from (both) sample 732W to 515W, while total average sprint time increased by 0.57s. Conclusions The Rast aerobic sprint test is an effective and practical tool for assessing anaerobic capacity and monitoring individual progress. The results confirm lactate accumulation and muscle fatigue. Targeted high-intensity anaerobic training can reduce FI and improve the anaerobic capacity of physical education and sport students.

Asthma is a chronic condition that affects breathing and quality of life, and rehabilitation is crucial for reducing symptoms and improving overall health. While pharmacological treatments manage symptoms, physiotherapy and kinesitherapy are recognized as effective methods of rehabilitation. This review discusses current therapeutic approaches for allergic asthma, including aerobic exercises, breathing techniques, and postural exercises. This article reviews contemporary research on kinesitherapy and rehabilitation methods in the treatment of allergic asthma. Using the Cochrane Risk of Bias tool, we assessed the quality of 25 randomized controlled trials (RCTs). Findings indicate that kinesitherapy improves lung function, reduces the frequency of asthma attacks, and enhances patient quality of life. Of the studies assessed, 12 showed a low risk of bias, bolstering the reliability of our conclusions. Nonetheless, methodological limitations in several studies highlight the need for rigorous research designs in future investigations of the effects of physical exercise on asthma rehabilitation. This review underscores the importance of a multidisciplinary approach and suggests integrating kinesitherapy into standard asthma treatment protocols. Asthma often leads to decreased physical activity due to symptoms such as shortness of breath; however, guided kinesitherapy in rehabilitation can reduce attack frequency, improve lung function, and lower medication needs. The study highlights the need for more research on optimal rehabilitation protocols for allergic asthma.

The purpose of the study was to evaluate and identifying the level of excess weight and obesity in older students between 15 and 18 years, as important benchmarks of the level of health in order to update the recommendations regarding the promotion of an active and healthy lifestyle. A cross-sectional study was conducted on a sample of 400 subjects, (186 boys and 214 girls), aged 15 to 18. Anthropometric data including: body height, body weight, Body Mass Index (BMI). Participants' BMI was estimated using the Percentile BMI calculator for children and teenagers aged 2 to 19. Study adolescents were defined as underweight, normal (healthy) weight, overweight, and obese according to the CDC child growth characteristics for age, sex, and BMI. 350 (85.5%) subjects were healthy weight; 26 respondents (6.5%) were overweight, 17 (4.25%), were obese, while 7 (1.75%) underweight. The analysis of the individual results of male and female subjects points to increased values of the body mass of males (18.81%), compared to female pupils (3%). Out of a total of 186 male students, 10.75% were in the overweight category, and 8.06% were categorized as obese, in constrast 2.80% of the girls were overweight and (1%<), in the obese category, which is an outstanding result, where obesity practically does not exist. According to the results of this study (for both sexes), in relation to gender, there were more malnourished girls (2.33%), compared to boys (1%<). Among high school students in Bosnia and Herzegovina, the number of children with overweight and obesity is relatively low compared to data from other countries. Based on the relevant results of this study, we consider it necessary to update strategies for promoting an active and healthy lifestyle regarding physical activity and eating habits for adolescents in relation to the specifics of the countries of residence and European trends. Keywords: BMI; students; overweight; obesity; weight status category; high school.

Background: Most human movements are supported by its functional capabilities of the anaerobic type, which is dominated by submaximal and maximal sports activities performed in a short time. Functional capabilities of the anaerobic type of man participate in most of his movement activities. Conditioned on adequate and extremely good interaction and functioning of the cardiovascular and respiratory systems, morphological status, metabolic processes, muscle structure, nutritional status, physical activity, etc. Purpose: The research was conducted in the conditions of the so-called field testing with the primary goal of assessing the acute state of anaerobic abilities of physical and sports students, by calculating the fatigue index (FI). Methods: The sample included 80 students of Physical and Sports Education, different geographical regions, average weight 77.88±8.49kg, age 20-23 years. The Running Anaerobic Sprint Test (RAST) was used to assess FI, and the basic statistical parameters were calculated. Results: The average value of the student's leg power is 573.89 watts (378.42 watts vs. 817.99watts), and the recorded average (FI) of 8.35 watts/sec (3.97watts/sec. vs. 16.93watts/sec.). Conclusions: The obtained results confirmed the average values of anaerobic capacity which are suitable for the examined population of subjects, while the maximal the value of FI suggests a weaker state of the anaerobic capacity of the individuals (less tolerance to lactates).

Introduction: We are increasingly witnessing the self-initiated, uncontrolled stacking of incompatible anabolic substances in various cycles in the young Balkan Recreational Bodybuilding population group, increasingly frequent acts of violence in our country and the emergence of a neglected and very silent epidemic that is taking on an increasingly aggressive course of illness and psychological behavior. Black market anabolic steroids are associated with many generally health problems and uncontrolled aggression behavior by abusers. Young unsolicited recreate bodybuilding are also associated with generalized atherosclerosis and potential increased high risk for heart disease that can structural and functional damage the cardiovascular system during muscle mass steroid cycles. Besides high calorie intake, elevating serum blood lipid cholesterol levels LDL lowering HDL levels, elevating, systolic and diastolic blood pressure take a certain participation in cardiovascular risk and therefor need a development of certain cardiovascular protection strategies for this avoiding medical supervision anabolic steroids abuser group which are not yet appropriate established. The aim of the short study was to estimate Cardiovascular Protective Strategy Measures on lipid levels, and blood pressure status in a young recreational bodybuilder with different ethnic groups who Abuse Anabolic Steroids during controversial and different mass Cycles with and without taking Polyunsaturated Fatty Acids and Acetylsalicylic Acid (ASA) and Statins. Subjects and methods: This study was conducted from beginning of January, 2022 till end of July, 2022. 140 subjects are included age 17-30 (74 male Recreational Bodybuilder Who Abuse Anabolic Steroids on Simvastatin’s 10mg and Acetylsalicylic Acid 150mg doses of (ASA) and 10 grams of Polyunsaturated Fatty Acids during mass Steroid Cycles and 66 impellers group of male Recreational Bodybuilder Who Abuse Anabolic Steroids consisting without consume Statins and Acetylsalicylic Acid (ASA) during mass Steroid Cycles). For the testing of statistical significance of differences between the exanimated groups non-parameter and parameter tests were used. The difference at a level of p< (0,001) was statistically significant. Results: In all the tested subjects we investigated increasing lipid levels and blood pressure after six months of study. Analysis shows the statistically insignificant influence of antiplatelet therapy (150mg Acetylsalicylic acid) (ASA), combined with Simvastatin 10mg p<(0,001) in steroid abuse subjects during irrational muscle mass steroid cycles. Conclusion: Lack of familiarity with combinations of anabolic substances, as well as the danger of oral applications of very harmful steroids from the former Soviet Union and German Democratic Republic (GDR), this study showed. Avoidance of physician supervision by recreate bodybuilders by deceiving of the athletic subjectivity look, seams appears almost always in gym. This cardiovascular protective measures have poor benefit appeared to be usefully blind preventing strategy of controlling blood lipid levels during muscle mass steroid cycles, with no guaranty of worsen cardiovascular condition by abusing anabolic steroids. The influence of the reflection of the COVID 19 virus on such dramatic therapeutic results in this population group of two groups cannot be ruled out for sure.
