Abstract

Background: Boxing is a high-risk combat sport with a high probability of head injuries, so effective prevention strategies are essential for athlete safety. However, empirical evidence on the implementation of head injury prevention programs at the training academy level is still limited. Objectives: This study aims to explore strategies and the practical implementation of head injury prevention at the HAN Boxing Academy, Malang. Methods: A qualitative case study design was used with purposive sampling. Four participants (one coach and three active athletes) were recruited. Data were collected through document review, direct observation, and semi-structured interviews, which consisted of 15 guiding questions. Data were analyzed using a thematic analysis approach, which involved data reduction, data presentation, and conclusion. Methodological triangulation was applied to enhance credibility. Results: Three main themes emerged: (1) systematic emphasis on basic defensive techniques to minimize head collisions, (2) mandatory and consistent use of head protection during training sessions, and (3) active supervision by coaches combined with a gradual rehabilitation protocol, including competition restrictions for up to six months after a serious head injury. Participants considered head protection effective in reducing the severity of impacts, although the residual risk of head injury was still acknowledged. Conclusions: Head injury prevention in academies is implemented through an integrated approach that combines technical skill development, the use of protective equipment, and continuous monitoring. To strengthen its effectiveness, it is recommended that structured injury prevention protocols be implemented and closer collaboration with medical professionals be fostered.

Abstract

Background: The FIFA 11+ program has been proven effective in preventing soccer injuries, but evidence regarding its impact on lower extremity functional outcomes is still scattered and reported heterogeneously. Objectives: This systematic review aims to synthesize evidence regarding the effects of the FIFA 11+ program on lower extremity functional outcomes—including ROM, knee extension, internal and external hip rotation, and hamstring muscle strength—in athletes. Methods: This systematic review was prospectively registered in PROSPERO (CRD420251147261) and conducted in accordance with PRISMA 2020 guidelines. A total of 14 studies involving athletes or physically active individuals met the inclusion criteria. Functional outcomes were measured using various instruments, primarily an isokinetic dynamometer for muscle strength and a goniometer for ROM measurement. The methodological quality of the studies was assessed using the Newcastle–Ottawa Scale. Due to substantial heterogeneity in study design, measurement instruments, intervention protocols, and reporting formats, a quantitative meta-analysis was not performed, and the data were synthesized using a qualitative narrative approach. Results: Most studies (approximately 70–80%) reported an increase in hamstring muscle strength after the FIFA 11+ intervention, particularly in concentric and eccentric isokinetic measurements. Improvements in ROM and functional outcomes of the knee and hip were also reported, although results varied between studies. Evidence related to knee extension and hip rotation shows lower consistency compared to hamstring strength. Conclusions: The FIFA 11+ program shows potential functional benefits beyond injury prevention, particularly in improving hamstring muscle strength and several aspects of joint mobility.

Abstract

Background: Lower limb muscle strength asymmetry is a significant factor that can impact playing ability and increase the risk of injury in soccer players. Differences in leg use and the specific movement requirements of a sport can lead to strength imbalances, either on both sides of the body or on the same side. Lower limb muscle strength asymmetry, particularly bilateral and ipsilateral strength asymmetry, is a significant factor influencing performance and increasing injury risk in football players. Differences in limb dominance and sport-specific movement demands can lead to strength imbalances. Objectives: This study aimed to compare bilateral and ipsilateral lower limb strength asymmetry between male and female football players. Methods: A cross-sectional study was conducted involving 50 amateur football players (26 males and 24 females; aged 18–21 years). Isokinetic strength testing of knee extensors and flexors was performed at 60°/s. Bilateral asymmetry was calculated based on peak torque differences between limbs, while ipsilateral asymmetry was assessed using the hamstring-to-quadriceps (H/Q) ratio. Statistical analyses included the Mann–Whitney U test and independent t-test (p < 0.05). Results: Significant sex differences were found in bilateral strength asymmetry for both quadriceps (7.21 ± 4.04% vs 5.04 ± 3.13%, p = 0.02) and hamstrings (9.13 ± 5.15% vs 5.06 ± 4.04%, p = 0.01), with males showing greater asymmetry. Female athletes demonstrated values closer to the recommended asymmetry threshold (≤10–15%). No significant differences were observed in ipsilateral strength asymmetry (H/Q ratio) between groups (p > 0.05). Conclusions: Bilateral strength asymmetry differs by sex, with male athletes exhibiting higher imbalance, while ipsilateral strength balance is comparable between groups. These findings highlight the importance of monitoring individual strength asymmetry to inform targeted training strategies, reduce injury risk, and optimize performance in football players.

Abstract

Background: Altered plantar pressure distribution and foot alignment have been suggested in previous studies to be associated with ankle instability and overuse injuries; however, evidence in youth populations remains limited. Objectives: This study aimed to investigate foot biomechanics and potential injury risk factors in youth football players aged 5–15 years. Methods: This study employed an analytical cross-sectional design involving 30 youth football players recruited from local football academies. Participants were categorized into three age groups: 5–9 years (n = 10), 10–12 years (n = 10), and 13–15 years (n = 10). Data were collected through pedobarographic plantar pressure assessment, hallux valgus angle (HVA) measurement using a goniometer, navicular drop test (NDT), and subtalar angle assessment. Statistical analyses included descriptive statistics, Shapiro–Wilk normality test, Pearson correlation, independent t-test, and one-way ANOVA with effect size (η²). A significance level of p ≤ 0.05 was applied. Results: The results showed that hindfoot plantar pressure was higher than forefoot pressure in both feet, indicating a posterior loading pattern. Hallux valgus angles were within normal ranges, while subtalar angles demonstrated a tendency toward pronation. Significant differences were observed in left foot HVA and left hindfoot pressure across age groups (p < 0.05), with moderate effect sizes (η² = 0.20–0.21). Correlation analysis revealed moderate to strong positive relationships between subtalar pronation and HVA variables. Conclusions: Youth football players exhibit biomechanical characteristics, such as increased hindfoot loading and subtalar pronation, that may represent adaptive responses to sport-specific demands and be associated with potential injury risk. However, given the study's cross-sectional design, these findings should be interpreted as descriptive biomechanical patterns rather than as direct predictors of injury. Early biomechanical screening and targeted preventive training may help support optimal athletic development.

Abstract

Background: Knee osteoarthritis (KOA) is a prevalent musculoskeletal disorder that leads to pain, reduced mobility, and functional limitations, particularly among overweight older adults. While exercise therapy is widely recommended as a primary non-pharmacological intervention, its effectiveness as a standalone approach may be limited due to increased biomechanical stress in this population. Objectives: This study aimed to evaluate and compare the effectiveness of exercise therapy alone and a combination of exercise and manual therapy on pain, joint function, range of motion (ROM), and physical performance in overweight older adults with KOA. Methods: A randomized controlled trial design was employed, involving 40 participants who were randomly allocated (1:1 ratio) using a computer-generated simple randomization sequence. Forty overweight older adults (mean age 58.3 ± 4.9 years; BMI 34.8 ± 3.2 kg/m²) with clinically diagnosed KOA participated in the study. Both groups underwent a 12-session physiotherapy program. Data were collected using the Visual Analog Scale (VAS) for pain, WOMAC for joint function, goniometry for ROM, and the Timed Up and Go (TUG) test for physical performance. Statistical analysis was conducted using JASP, including descriptive statistics, independent-samples t-tests, paired-samples t-tests, repeated-measures ANOVA, and ANCOVA to control for potential confounders. Results: Both groups demonstrated significant improvements in all outcome measures. Compared with exercise alone, the combined intervention resulted in greater pain reduction (adjusted mean difference = -1.07 points, p < 0.001, η² = 0.52), greater improvement in knee ROM (p < 0.001, η² = 0.61), and better TUG performance (p = 0.001, η² = 0.46). No significant between-group difference was observed for WOMAC scores (p = 0.234, η² = 0.03). Conclusions: The combination of exercise and manual therapy is more effective than exercise alone in improving pain and physical performance in overweight older adults with KOA. A multimodal physiotherapy approach is recommended to optimize rehabilitation outcomes in this population.

Abstract

Background: Multiple physical and physiological factors influence sprint swimming performance; however, the relative contributions of isometric strength, isokinetic strength, and anaerobic power to 100-m freestyle performance in young swimmers remain unclear. Objectives: This study investigated the associations and predictive contributions of physical characteristics, isometric and isokinetic upper-body strength, and anaerobic power to 100-m freestyle swimming performance in young swimmers. Methods: A cross-sectional study was conducted with 21 male swimmers aged 10–13 years, selected purposively. Eligibility criteria included a minimum of three years of structured swimming training, regular participation in 3–5 training sessions per week, and absence of musculoskeletal injuries. Upper-body strength was assessed using isometric and isokinetic dynamometry (60°/s and 180°/s), while anaerobic power was measured using the 30-s Wingate Anaerobic Test. Swimming performance was evaluated using a 100-m freestyle time trial. Pearson correlation and linear regression analyses were performed after verification of regression assumptions. Results: Swimming speed was significantly correlated with isometric elbow flexor strength (r = .49, p < .05), isokinetic flexor strength at 60°/s (r = .41, p < .05), and Wingate peak power (r = .37, p < .05). Simple linear regression analysis identified isometric elbow flexor strength as the strongest predictor of swimming performance (B = 0.005, p = .026, R² = .235), followed by isokinetic flexor strength at 60°/s (B = 0.004, p = .038, R² = .210) and Wingate peak power (B = 0.001, p = .031, R² = .198). No significant associations were observed for isokinetic strength at 180°/s. Conclusions: Upper-body muscular strength, particularly isometric elbow flexor strength, is a significant determinant of 100-m freestyle swimming performance in young swimmers. These findings highlight the importance of maximal force-generating capacity, alongside anaerobic power development, for sprint swimming performance.

Abstract

Background: Training programs during adolescence play a crucial role in optimizing body composition and physical performance in youth soccer players. However, differences in training adaptations between age groups, particularly in agility performance, remain insufficiently explored. Objectives: This study aimed to examine the effects of a seasonal soccer training program on body composition, strength, and agility in U-15 and U-17 soccer players. Methods: A pre–post experimental design was applied to 28 male youth soccer players (U-15: n = 15; U-17: n = 13) competing in a football league in the Netherlands. Participants completed a 16-week training program consisting of technical, conditioning, tactical, and mental components. Body composition (height, body mass, lean mass, fat mass), jump performance (SJ, CMJ, CMJmax), isokinetic strength (knee flexion and extension peak torque), and agility (Illinois Agility Test) were assessed before and after the intervention. Data were analyzed using repeated-measures analysis of variance (ANOVA) and effect sizes were calculated using Cohen’s d. Results: In the U-15 group, significant improvements were observed only in knee flexion (70.2 ± 15.8 vs. 95.4 ± 23.5 Nm, p = 0.006, d = 1.25) and extension peak torque (75.1 ± 20.4 vs. 96.8 ± 18.9 Nm, p = 0.012, d = 1.10). In contrast, U-17 players demonstrated significant increases in lean mass (50.2 ± 3.1% vs. 53.4 ± 2.3%, p = 0.021), reductions in fat mass (11.0 ± 2.9% vs. 8.7 ± 2.5%, p = 0.037), improvements in agility performance (16.2 ± 0.7 vs. 15.4 ± 0.65 s, p = 0.008, d = 1.18), and knee flexion peak torque (78.4 ± 26.5 vs. 118.3 ± 28.7 Nm, p = 0.003, d = 1.45), together with significant gains in jump performance (p < 0.05). Most significant changes in the U-17 group were accompanied by large effect sizes (d = 0.85–1.45). Conclusions: The training program elicited greater physiological and performance adaptations in U-17 compared to U-15 players. The greater adaptations observed in the U-17 group may be partially influenced by differences in biological maturation; however, maturity status was not directly assessed in the present study.
