Sports injuries were prevalent across various sports and resulted in temporary or permanent limitations in an athlete’s competitive performance. This research aimed to compile and analyze studies on sports injuries among basketball, handball, and volleyball players, with a particular focus on their frequency, nature, and variations based on gender and player position. A systematic search was conducted using digital databases, including PubMed, MEDLINE, ERIC, Google Scholar, and ScienceDirect, covering the period from 2015 to 2025. The search strategy involved relevant keywords and their combinations related to injuries and athletes, selecting studies that explored injury types, locations, and preventive measures. The findings indicated that lower limb injuries were the most prevalent in all three sports. Basketball players frequently experienced knee and ankle injuries, and handball players were prone to knee injuries, while volleyball players most commonly sustained knee and foot injuries. Additionally, specific risk factors contributing to these injuries were identified. Preventive interventions, such as neuromuscular training and plyometric exercises, were found to effectively reduce injury rates across these sports. The majority of studies suggested that female athletes had a higher injury incidence compared to their male counterparts. This may be attributed to several factors, including hormonal differences (such as the effect of estrogen on ligament laxity), anatomical factors (e.g., a larger Q-angle in women), and differences in training practices that could predispose female athletes to higher injury rates. Furthermore, regardless of the sport, injuries occurred more frequently during competition and tended to increase with the physical demands of the game.

Contemporary top-division soccer is characterized by high-intensity activity throughout the entire match, which also requires high levels of a wide range of the players’ functional and motor abilities. Furthermore, motor and functional requirements vary in relation to the players’ position on the pitch. In view of the above, the objective of this study was to determine any differences in body composition and specific motor abilities in relation to position. Twenty elite female soccer players (age: 20.90 ± 3.70 years; height: 166.95 ± 5.83 cm; weight: 58.97 ± 7.50 kg; training experience: 9.50 ± 4.11 years) were recruited for the purpose of this study. Based on their position within the team, the players were divided into three groups: defenders (N-7), midfielders (N-6), and forwards (N-7). The instruments used included the InBody770 (for body composition assessment), Optojump and Polar for the assessment of specific motor abilities. The results obtained indicate a strong link between the parameters body composition and specific motor abilities; however, the level of significance varies, as do the variables concerning specific motor abilities and body composition in relation to the players’ position on the pitch. In accordance with these results, coaches and others working in the soccer industry should be apprised of the necessity of a tailored approach when it comes to planning the development of specific motor abilities, as well of with the importance of balanced body composition as prerequisites for achieving top results.

This study aimed to explore whether a 16-week Teaching Games for Understanding (TGfU) volleyball intervention could improve primary school students’ physical fitness and body composition. Eighty-eight primary school students (age 13.3 ± 0.3 years) were randomized to a TGfU volleyball intervention group (VG) or a control group (CG). The CG attended three regular physical education (PE) classes per week, while the VG attended two regular PE classes and a TGfU volleyball intervention that was implemented in the third PE class. Body composition components (body weight, body mass index, skinfold thickness, body fat percentage, and muscle mass percentage) and physical fitness (flexibility, vertical jumps (squat and countermovement jump—SJ/CMJ), 30 m sprint, agility, and cardiorespiratory fitness) assessments were performed pre-and post-intervention period. Significant interaction effects between VG and CG and pre- and post-test were found for the sum of five skinfolds (p < 0.0005, ŋp² = 0.168), body fat % (p < 0.0005, ŋp² = 0.200), muscle mass % (p < 0.0005, ŋp² = 0.247), SJ (p = 0.002, ŋp² = 0.103), CMJ (p = 0.001, ŋp² = 0.120), 30 m sprint (p = 0.019, ŋp² = 0.062), agility T-test (p < 0.0005, ŋp² = 0.238), and VO_2max (p < 0.0005, ŋp² = 0.253). Further examination revealed a greater improvement among VG students compared to CG students in certain body composition and physical fitness outcomes. Implementing a TGfU volleyball intervention in the physical education curriculum appears to have effective stimuli for reducing adiposity and promoting physical fitness levels in seventh-grade primary school students.

Background: This study aimed to explore the effectiveness of a 12-week circuit training program in improving local muscular endurance in normal-weighted primary school students. Methods: The study involved a parallel-group randomized trial with 606 primary school boys assigned to an experimental or a control group. The participants underwent a 12-week circuit training program that involved multi-joint, total-body workouts using body weight, resistance bands, and medicine ball exercises. The study measured the participants’ local muscular endurance during sit-ups, dynamic trunk extensions on a Roman bench (DTE), and push-ups. Results: After adjusting for the baseline, the treatment–grade interaction was significant for sit-ups (F = 7.74, p < 0.001, η_p² = 0.04), DTE (F = 6.49, p < 0.001, η_p² = 0.03), and push-ups (F = 9.22, p < 0.001, η_p² = 0.05), where the experimental treatment was more beneficial than the control. The treatment effect seemed to vary depending on the individual’s baseline local muscle endurance capacity. As the baseline local muscular endurance values increased, the treatment and grade effects became less beneficial. Conclusion: A 12-week circuit training program involving body weight, resistance bands, and medicine ball exercises suits school-based programs and can improve local muscular endurance in normal-weighted primary school boys. The experimental treatment was more effective than the control, and the individual baseline muscular endurance should be considered when designing training programs.

The main goal of this work is to get acquainted with the theoretical and methodical bases of training football players, which are of permanent importance for achieving high sports results. This work should help to acquire basic knowledge that will enable real coaching creativity, creativity in work, finding new ideas, exercises and methodological procedures in training and creating high-quality players and teams. Preparing top footballers capable of representing their country at the international level is not a simple, but a very extensive and complex pedagogical process. The basis of that process must be based on the fact that there have been changes in the modern football game, as well as on continuous familiarization with the latest achievements in the method of preparing football players. The only real approach to the development of training methodology in football is to define the typology of efforts that players undergo during the game. For these purposes, the quantitative structures of their movement and the technical-tactical structure of their activity were analyzed in the paper.
