The aim of the research was to investigate the immediate effects of a TRX-specific warm-up on crawl stroke speed, muscle strength, and shoulder range of motion (ROM) in young competitive swimmers. Sixteen young competitive swimmers (mean age: 11.31 ± 1.6 years) participated in this study. Participants were matched based on crawl stroke speed and randomly assigned into two groups: (1) the intervention group, which performed a TRX-specific warm-up (n = 8), and (2) the control group, which performed a traditional swimming warm-up (n = 8). Muscle strength and shoulder range of motion (ROM) were measured immediately after the intervention. Following a 10-minute rest period, participants performed 50- and 100-meter crawl stroke swims to assess swimming speed. Results showed the intervention group significantly improved their 100-meter swimming speed and demonstrated an increase in left shoulder internal rotation range of motion (p < 0.05). However, no significant differences were observed in 50-meter swimming speed or muscle strength parameters. The control group showed no significant changes in any of the measured variables. Findings suggest incorporating a TRX-specific warm-up may enhance 100-meter swimming performance in young competitive swimmers. Therefore, including TRX exercises in pre competition warm-ups is recommended to improve swim performance.

THE IMPACT OF PHYSICAL ACTIVITY ON LEVELS OF DEPRESSION AND ANXIETY IN YOUNG ADULT WOMEN

Nevres Muminović — 2026-06-23

Modern lifestyles are often accompanied by increased levels of stress, anxiety, and depressive symptoms, which are particularly pronounced among the young adult population. Physical activity is increasingly recognized as an important factor in maintaining and improving mental health. The aim of this study was to examine the effects of a structured recreational activity program on levels of depression and anxiety in young adult women. The study included 35 women aged 20 to 40 years. The experimental program lasted three months, during which participants engaged in organized recreational activities twice a week, with each session lasting one hour and conducted under professional supervision. Data were collected before the beginning and after the completion of the experimental period using standardized measurement instruments. Basic descriptive statistical parameters were used for data analysis. The results showed a decrease in the mean values of most variables related to depressive and anxiety symptoms in the final measurement compared to the initial one. The overall depression score decreased from 5.94 to 4.86, while anxiety scores decreased from 5.57 to 4.91. The findings indicate a positive effect of the three-month recreational activity program on reducing symptoms of depression and anxiety among participants. Based on these results, it can be concluded that regular physical activity plays a significant role in maintaining mental health and can contribute to the reduction of depressive and anxiety symptoms in young adult women. The results emphasize the importance of incorporating organized recreational activities into daily life as a potential means of improving psychological well-being.

DIFFERENCES IN THE MANIFESTATION OF FRONTAL–LATERAL AGILITY BETWEEN KARATE ATHLETES AND BOXERS

Eldar Goletić — 2026-06-23

This study was conducted on a sample comprising 60 athletes aged 13–15 years from the Tuzla Canton, including 30 karate practitioners and 30 boxers. The karate participants were members of the clubs “Konjuh” (Živinice) and “DO” (Tuzla), whereas the boxers were members of the boxing clubs KBS “Banovići” (Banovići), BK “Živinice” (Živinice), KBS “Radnički” (Lukavac), BK “Grad” (Tuzla) and BK “Feniks” (Tuzla). Frontal–lateral agility in this research was operationalized through three separate agility variables: T- test agility (MAGTTAG), Movement in Two Triangles (MAGKDTR) and Side Steps (MAGKUST). The primary aim was to determine differences in the manifestation of frontal– lateral agility between karate athletes and boxers. An independent samples t- test for small samples was applied to evaluate inter- group differences. Inspection of the t- test results and comparison of arithmetic means indicated differences across all frontal–lateral agility variables (MAGTTAG, MAGKDTR and MAGKUST). However, only two of the three variables: Movement in Two Triangles (MAGKDTR) and Side Steps (MAGKUST) showed statistically significant differences; the difference observed in T- test agility (MAGTTAG), although evident, did not reach statistical significance. The specific movement structure in karate, characterized by minimal oscillation of the body's center of mass, contributed to better frontal–lateral agility among the karate sample. The findings pertain to the examined groups of karate practitioners and boxers.

DIFFERENCES IN THE FUNCTIONAL MOVEMENT PATTERNS OF YOUNG FEMALE ATHLETES BASED ON THEIR SELECTED SPORTS DISCIPLINE

Lejla Goletić — 2026-06-23

Functional Movement Screening (FMS) consists of seven tests that provide a simple yet reliable assessment of mobility, stability, and overall musculoskeletal function. The study included 40 girls aged 9 to 12 years, who were divided into two groups according to the sport they practiced karate and artistic gymnastics. The karate group consisted of members of Karate Club Konjuh, while the gymnastics group included members of Gymnastics Club Salto. All participants were healthy and had not sustained any injuries in the previous six months, which enabled an accurate assessment of their functional status. The aim of the study was to examine whether there were differences in the quality of fundamental movement patterns between the athletes. The tests enabled the identification of potential asymmetries or weaknesses that may arise as a result of sport-specific training loads. The data were analyzed using descriptive statistics within the SPSS 26 software package. Levene’s test was used to assess the homogeneity of variances between the groups, while an independent samples t-test was applied to determine differences between the groups. The results revealed statistically significant differences in the Active Straight Leg Raise (ASLR) and Rotary Stability (ROT) tests. The findings suggest that tailored and individualized training programs may play an important role in improving functional movement patterns and reducing the risk of injury in young athletes.

ANALYSIS OF PARAMETERS OF TEAM SITUATIONAL EFFICIENCY OF WOMEN'S FOOTBALL U17 NATIONAL TEAMS AT THE 2022 EUROPEAN CHAMPIONSHIP

Merima Aljić — 2026-06-23

The sample of entities consists of 15 winning national teams classified in the entity group "WIN" and 15 defeated national teams classified in the entity group "DEFEAT". For this research, we used only those matches where the final winner was obtained after the regular part of the match, as well as the players of the winning and defeated teams who spent all 90 minutes on the field. The subject of this research refers to the analysis of team situational efficiency parameters in women's U17 football teams participating in the European Football Championship held in Bosnia and Herzegovina. The problem of this research is to determine the differences in the parameters of team situational efficiency between winning and defeated teams. The data obtained within this research were processed using the following descriptive procedures: Modus, Median, Frequency, Valid Percent and Cumulative Percent. To determine the differences between the winning and losing teams in the variables used to assess team and individual situational efficiency, we used the Median test. Based on the results obtained, we can say that the winning and defeated teams/representations differ in the parameters of team situational efficiency in six variables: the total number of attempted shots on goal, the number of goals scored in the match, the number of shots on goal, the number of shots outside the goal, the number of assists and number of goals conceded.
