The aim of this research was to examine the relationship between absolute and relative lower extremity strength and the efficiency of gymnastics vault performance. Thirty healthy, physically active male students (age: 20.84 ± 0.99 years; height: 179.46 ± 5.91 cm; body weight: 73.88 ± 6.43 kg) from the Faculty of Sports and Physical Education participated in the study. Absolute lower extremity strength was assessed by measuring the maximum load lifted (in kg) during a back squat (1RM). Relative lower extremity strength was calculated by dividing the estimated 1RM back squat by the participant's body weight (1RM/BW). Two types of vaults—the squat through (ST) and the front handspring (FHS)—were used to evaluate vault performance efficiency. Three criterion variables were applied: (d1) distance from the springboard in front of the vault, (d2) distance of landing beyond the vault, (d1 - d2) the difference between d1 and d2, and (pt) overall vault performance rating. The results showed statistically significant and strong correlations between both absolute and relative lower extremity strength and the variables measuring vault performance efficiency. The strongest correlations were observed for (d1), followed by (d2), (pt), and (d1 - d2). These findings can serve as guidelines for developing both absolute and relative lower extremity strength, which may lead to improved performance in gymnastics vaults.

In this study we analyzed the effects of swimming on the posture of preschool children. The sample for this study consisted of 153 preschool boys and girls children aged 4-6 years (standard deviation= 1.1 years) living in Canton Sarajevo and divided into two groups of boys and girls, with one attended swimming school (n=61) and other did not (n=92). In order to evaluate the postural status, we used a reduced Napoleon Wolanski method with eight variables for the observed body parts: assessment of head posture (HPA), assessment of shoulder posture (SPA), assessment of scapular posture (SBPA), assessment of chest posture (CPA), scoliotic posture (SCP), assessment of abdominal posture (APA), assessment of leg posture (LPA), and assessment of foot posture (FPA). The results indicated a great effect of swimming on posture. We concluded the paper with some suggestions on how to incorporate swimming programs into regular school curricula.

Purpose. The aim of the study was to examine the effects of five weeks detraining period on body composition changes in elite professional Indonesian male soccer players. Material and methods. The body composition of 24 top-level male soccer players (age: 26.33 ± 4.06 years) competing in First League of Indonesia was measured before and after the 5-weeks detraining period. Body composition variables, including body mass, body fat percentage, fat-free mass, and total body water percentage, were measured using the bioelectrical impedance method. The results. The paired samples T-test showed significant changes in the means of body composition variables for body fat percentage, fat-free mass, and total body water percentage. Mean values for body fat percentage increased during the detraining period from 10.87 ± 2.47% to 11.98 ± 2.75% (10.3%). A decrease in mean values for fat-free mass (61.34 ± 5.74 kg to 59.80 ± 6.22; 2.49%) and total body water percentage (from 65.13 ± 1.84% to 64.40 ± 1.99%; 1.12%) was observed. No significant changes occurred in body mass (from 69.05 ± 8.07 kg to 69.05 ± 8.48 kg; 0.04%) from initial to final testing. Conclusions. Since there was a significant difference in body fat percentage, fat-free mass, and total body water percentage% before and after detraining period., it is suggested that 5 weeks of detraining period.  for the professional soccer players may not be necessary, and the duration should be shortened to maintain body composition status.

The issue of spinal deformities, which occurs during phases of intense growth in children, has been recognized within the broader community. Certain categories of children are particularly vulnerable to long-term health risks in this regard, making it important to find ways to intervene early and identify such cases. This study was conducted to assess the current state of spinal posture during one of the most sensitive phases of physiological development in a special group of preschool children. In this case, the sample included 92 preschool children aged 4 to 6 years, who have been living and growing up from an early age in the SOS Children's Village in Sarajevo, without the presence of their biological parents. The assessment of poor posture was applied according to Napoleon Wolanski (1975), which is based on determining the relationships between segmental dimensions as follows: D1 – assessment of head posture (HPA), D2 – assessment of shoulder posture (SPA), D3 – assessment of chest posture (CPA), D4 – assessment of scapula posture (SBPA), D5 – assessment of spinal posture (SP), D6 – assessment of abdominal posture (APA), D7 – assessment of leg posture (LPA), D8 – assessment of foot posture (FPA). Deviations are classified according to their severity and are assessed with so-called negative points, where: 0 points indicate no deviation, 1 point indicates a mild deviation, and 2 points indicate a significant deviation. The posture results show that 15.2% of the children have scoliosis, while 13.0% have lordosis, and 7.6% of preschoolers have kyphosis. Additionally, 30.4% of the children have flat feet, which predisposes them to long-term spinal problems, and 33.7% have significant deviations in leg posture. Numerical values of the results indicate that none of the children included in the testing had an ideal shoulder posture, i.e., a score of 0, which implies no deviation from normal, while the head posture results were also extremely poor.

The primary aim of this study was to examine the body composition of young female rhythmic gymnasts and draw comparative insights from the collected data. Additionally, the results were compared with other studies that shared identical or analogous research objectives. 36 girls divided into three age groups participated in the research: Group 1 (age: 8.57 ± 0.66), group 2 (age: 10.32 ± 0.48) and group 3 (age: 12.90 ± 0.74). Body composition was determined using an octopolar bioelectrical impedance analysis device InBody 370. Among the various variables assessed, the groups exhibited statistically significant differences across most parameters, with exception of body fat (%). Our results, consistent with prior research studies, revealed that our participants also exhibited the characteristic body composition commonly observed in rhythmic gymnastics. These findings suggest that rhythmic gymnastics primarily affects body weight and the percentage of body fat tissue, while also contributing to the development of muscle mass over years of training and sports experience.

Introduction: Bilateral ectopic pregnancy is a very rare condition which occurs in 1/725 - 1/1580 ectopic pregnancies, most commonly after induced assisted reproductive techniques. Aim: To present the case of spontaneous bilateral tubal pregnancy, and the problem of insufficiency of available diagnostic methods, which causes that an accurate diagnosis can mostly be made intraoperatively. Case Report: A 37-year-old female, nulliparous, comes at the Clinic of Gynecology and Obstetrics of CCUS, complains of intense suprapubic pain, and difficulty urinating. The expected menstruation was absent for more than 2 weeks. The Grav index test was positive. Beta hCG values were 6312 IU/L. On examination, the patient was extremely pale, hypotensive, gave the impression of hemorrhagic shock, and the abdomen was diffusely palpably painful. After emergency TV ultrasound, then ultrasound and CT of the abdomen and small pelvis, which indicate a moderate amount of thicker fluid in the abdomen and small pelvis in terms of hemoperitoneum and with the left contour of the uterus an oval zone most likely to correspond to ectopic pregnancy, an indication for emergency surgery was made. A laparotomy was performed, and partly liquid and partly coagulated blood was found in the abdomen. The left tube in the isthmic part was ruptured with active bleeding. Right Fallopian tube was pathologically changed, livid, with visible suspicious pregnancy in the ampullary part. Bilateral salpingectomy was performed, and samples are sent for PHD analysis that shows the presence of chorionic villi in both tubes. Conclusion: When ectopic pregnancy is suspected, the possibility of bilateral tubal pregnancy should always be kept in mind, especially in cases accompanied by acute pelvic pain with signs of hemorrhagic shock

Conflict is an integral part of sport, and it implies a normal occurrence in communication and relationship between athletes and coaches. The main aim of this paper was to present a conflict analysis of the coach-athletes relationship, but also its impact on the achievement of sports results. The review article analysed nine works that directly studied interpersonal relationships between coaches and athletes. Research results suggest that conflict is evident and inevitable, as well as expected since coaches spend a lot of time with athletes, and pass through the training process, but also the competition period, when athletes are exposed to greater pressure because of the competition itself. Timely response and adequate response to conflict can greatly contribute to improving relations and even better sports results.

This study aimed to examine the relation between agility, sprint ability, and vertical jump performance of young basketball players. Fifty (n=50) young basketball players (mean±SD: age = 12.63±0.95; height = 160.84±6.31 cm; body mass = 50.82±6.88 kg) participated in the study. The agility T-test and 505 test were assessed to determine agility, 10m and 20m sprint was measured to determine sprint ability and countermovement jump (CMJ) for jumping performance. The results of Pearson’s Product Moment Correlation analysis indicated large to very large relation between agility tests and sprint performance (r = 0.61 to 0.85); agility and jump performance (r = - 0.64 to - 0.67); sprint and jumping performance (r = -0.59 to -0.77). The results of the study suggest that agility, sprint, and jumping performance share common physical demands, therefore it is necessary to develop them during the training.
