Abstract

Background: Thousands of athletes perform kipping handstand push-ups (kHSPUs). The safety of kHSPUs has been questioned because of vertical impacts upon the head, but no previous study has examined the ground reaction forces sustained during these exercises.Aims: This exploratory, observational cross-sectional study measured the forces exerted on the head and supported by the neck during kipping handstand push-ups (kHSPU). The goal was to compare these forces with known thresholds that can damage the cervical spine. The researcher also aimed to determine how often people experience symptoms after performing these exercises.Methods: Sixteen volunteers performed three sets of up to 7 kHSPUs with their head and one hand contacting force platforms. Force and video recordings were made while performing the exercises. Volunteers were asked if they had neck pain or headaches related to the exercises.Result: Force profiles showed distinct landing and kipping peaks. Landing forces were higher than during a headstand but less than body weight. Forces were greatest during the "kip" and usually exceeded body weight. Participants who reported pain following kHSPUs extended their necks during the exercises. Forces to the head during kHSPUs were below forces proposed for damage to the young male cervical spine but overlapped those proposed for damage to female cervical spines.Conclusion: While kipping handstand push-ups may be safe for young and previously uninjured male athletes, they may be unsafe for females and those with previous injuries or other compromising factors. Detailed inquiry about symptoms and neck injuries secondary to these exercises is warranted. Based on the initial observations, until these exercises are shown to be safe, athletes should be informed about these possible risks before performing the exercises.

Abstract

Background: Improving the functional fitness of elite football players requires specialized training techniques that align with structured sport-specific programs. High-Intensity Functional Training (HIFT) and the Oxford System are emerging methods incorporated into weightlifting programs to enhance physical and skill-related attributes in football athletes. This study explores their effectiveness compared to traditional weightlifting methods.Aims: The study aims to assess the impact of HIFT and Oxford System exercises on football players' physical and skill development, focusing on explosive force, speed power, maximum speed, dribbling, passing, and scoring.Methods: Twenty-four football players from the Darbandikhan Sports Club (2021–2022 seasons) were purposively allocated into an experimental group (HIFT and Oxford System) and a control group (conventional weightlifting). Physical and skill-related characteristics were measured through pre-tests and post-tests to evaluate improvements.Results: The experimental group significantly improved physical and skill-related attributes between the pre-test and post-test. Post-test results revealed that explosive force, speed power, and maximum speed were significantly higher than in the control group (t = −4.257, p = 0.002). Skill-related dribbling, passing, and scoring improvements were also statistically significant (t = 1.147, p = 0.001; 1.264, p = 0.002; 4.287, p = 0.004). The experimental group outperformed the control group across all measured criteria.Conclusion: The findings indicate that HIFT and Oxford System exercises effectively enhance football players' crucial physical and skill components. Incorporating these training methods into structured programs can significantly improve players' athletic performance.

Abstract

Background: Although corner kicks are the most tactically analyzed set pieces in professional soccer, there is still no consensus on whether inswinging or outswinging deliveries are more effective, and no previous meta-analysis has systematically addressed this question.Aims: The study aimed to compare the offensive effectiveness of inswinging and outswinging corner kicks, specifically concerning goal conversion and the creation of final attempts, while also examining differences between domestic and international competitions.Methods: A meta-analysis was conducted using data from 12 eligible studies involving professional competitions. Binary outcomes (goal vs. no goal; final attempt vs. no attempt) were analyzed using log odds ratios under a random-effects model to account for heterogeneity. Subgroup analyses were performed based on competition type (domestic vs. international).Result: The cumulative goal conversion rate from corners was 3.09%, while the rate for final attempts was 25.61%. No statistically significant difference was found between inswinging and outswinging corners regarding goal conversion (OR = 0.99, p = 0.67). However, outswinging corners increase the probability of a final attempt (OR = 0.79, p = 0.02) compared to inswinging corners.Conclusion:  This first meta-analysis comparing corner kick delivery types shows that, while both are equally effective for scoring, outswinging corners lead to more final attempts. Coaches may prioritize outswinging deliveries to improve offensive output and reduce counterattack risk. Future studies should examine contextual factors (e.g., marking systems, delivery zones) and include defensive outcomes for a more holistic tactical understanding.

Abstract

Background: Understanding how effective coaching impacts athlete success is crucial to understanding how high-performance teacher-coaches manage their dual teaching and coaching roles and develop their professional skills throughout their careers.Aim: This study examined the key learning sources contributing to the professional development of teacher-coaches in Japan.Methods: This study adopted a mixed-methods approach involving eight male teacher-coaches with over 20 years of successful coaching experience. Participants completed a questionnaire rated on a 7-point Likert scale regarding the importance of various learning sources throughout their careers. Additionally, semi-structured interviews were conducted to gain an in-depth understanding of their learning experiences.Results: Quantitative analysis showed that the learning sources changed across career phases: "Learning as a teacher" (20s), "On-the-job experience" (30s–50s), and "Reflection" (60s). The qualitative analysis revealed three main themes: Learning as a teacher (20s), On-the-job experience (30-50s) and Reflection (60s). These themes illustrated how the sources contributed to the development of their coaching skills—early teaching responsibilities nurtured intra- and interpersonal competencies, while later stages emphasized the cultivation of reflective practices.Conclusions: The findings contribute valuable insights into improving coach development programs, ensuring teacher-coaches ongoing growth and success in their dual roles. Coach developers should encourage teacher-coaches to foster intra- and interpersonal knowledge through teaching and various other learning opportunities.

Abstract

Background: Career and life satisfaction are critical factors influencing football coaches' well-being, performance and future. However, the role of coaching efficacy as a mediator between these two factors remains underexplored, particularly in the context of football coaching in Türkiye.Aims: The present study examines the mediating role of coaching efficacy in the relationship between football coaches' careers and life satisfaction.Methods: The research group, which adopted a quantitative approach, consists of individuals with football coaching licences in Türkiye (n=429). The parametric tests were used in the analyses, and a modern approach was adopted for the mediation analysis. Furthermore, ANOVA was applied to the analysis of differences, and the Pearson correlation test was applied to the relationship between concepts. In addition, the difference between the groups was determined by the Tukey test.Result: The age factor did not affect coaching efficacy. However, experience and license categories were found to be important factors. The structural model constructed for the research was confirmed (Δχ²/sd=1.94; RMSEA=.05; CFI=.95; GFI=.90; IFI=.94).Conclusion: The study determined that coaching efficacy mediated the relationship between coaches' career and life satisfaction. Coaching efficacy plays an important role not only for the athletes but also for their own lives. Therefore, it is recommended that football coaches give importance to professional efficacy and improve themselves to achieve career and life satisfaction.

Abstract

Background: Team climate plays a crucial role in athletes' psychological well-being and performance. While sports participation fosters social connections and mental wellness, athletes also face stressors that impact their motivation and well-being.Aims: This study aimed to assess the levels of psychological needs satisfaction (PNS), psychological need thwarting (PNT), burnout (BO), controlling coach behavior (CCB), and team climate (TC) among athletes. It also examined the relationships among these variables, identified key predictors of team climate, and determined the best-fitting model explaining team climate in a sports context.Methods: A descriptive-correlational design and Structural Equation Modeling (SEM) were used to analyze data from 57 competitive athletes. PNS, PNT, CCB, and BO were measured to identify key predictors influencing TC and its model parsimony.Results: Mean scores indicated moderate to high levels of PNS (x̄=5.87), PT (x̄=3.30), BO (x̄=3.00), CCB (x̄=2.90), and TC (x̄=5.53). Correlation analysis revealed that PNS positively correlated with TC (r=0.545; p<0.01), while PT (r=-0.362; p<0.01) and BO (r=-0.200; p<0.05) negatively correlated with TC. Multiple regression showed that PNS (β=0.626; p=0.000), PT (β=-0.504; p=0.000), and BO (β=0.423; p=0.004) significantly predicted TC, with an R² of 0.505. Among of the generated models, hypothesized model 4 met the high threshold indices (CMIN/DF=1.102, RMSEA=0.02, GFI=0.981, CFI=0.958, TLI=0.972, NFI=0.956).Conclusion: PNS emerged as the strongest predictor of TC, while PNT hindered it. Surprisingly, BO positively influenced TC, suggesting shared adversity may strengthen cohesion. CCB did not directly predict TC but indirectly influenced BO. The findings highlight the importance of athlete-centered coaching in fostering supportive teams and well-being.

Abstract

Background: Body composition, leg strength ratio, and handgrip strength could significantly affect and predict aspects of health and athletic performance. We explored the association between body composition (BC), leg strength (LSR), and hand grip strength (HGS) among university athletes in different sports.Aims: to investigate the multiple influences of these physical factors through other sports to provide a more integrated understanding of the total effect of these factors on athlete performance and selection.Methods: Sixty-six university athletes (age: 22.76± 2.11y, BMI 21.57± 3.04 kg/m2) were enrolled for our study. The participants (39 males and 27 females) participated in cricket, volleyball, and athletics. Body composition (BC), including lean body mass (LBM), muscle mass (MM), skeletal muscle mass (SMM), body fat mass (BFM), basal metabolic rate (BMR), hand grip strength (HGS), and leg strength ratio (LSR), was assessed. A chi-square test and independent sample t-tests analyzed the differences between categorical and continuous variables. A one-way ANOVA was used to analyze the multiple comparisons (BMR, LSR, BFM, and HGS) across cricket, volleyball, and track and field athletes.Results: The mean BFM in volleyball players was higher than in track and field athletes (14.20 ± 6.28 vs 8.44 ± 3.15, p<0.05). Analysis with a linear regression model adjusted for age, sex, BMI, and smoking habit indicated that LBM and BFM of participants were positively associated with HGS (p<0.05). However, an increase in HGS was associated with greater LSR in cricket (p< 0.001), volleyball (p <0.0001), and track and field athletes (p< 0.01).Conclusions: Our findings suggest that body composition, hand grip strength, and leg strength may be useful in player selection and improving performance for specific sports. Our results indicate increased hand grip strength is associated with greater leg strength.

Abstract

Background: Big Data Analytics (BDA) is urgently needed in Indonesian sports to improve evidence-based decision-making, athlete development, and organizational management. While BDA has transformed global sports through data-driven insights, its application in Indonesia remains limited and fragmented. The absence of integrated analytics between athlete performance and organizational quality management hinders the creation of sustainable, long-term development systems. Aims: This study investigates how BDA can enhance athlete development and organizational management by analyzing multidimensional data from athletes, coaches, referees, and sports infrastructures. It also aims to identify dominant predictors of athlete performance across various sports and to evaluate the quality management practices of the National Sports Committee of Indonesia (NSCI). Methods: A mixed-methods sequential explanatory design was applied. The quantitative phase involved 67 athletes from six sports: football, table tennis, weightlifting, pencak silat, basketball, and karate at the Sport Training Center. Data on anthropometry, fitness, and achievements were analyzed using descriptive statistics, ANOVA, Chi-Square, and regression tests. The qualitative phase involved interviews and observations with 8–12 stakeholders, while organizational quality was assessed using the Wilcoxon Signed Rank test. Result: Results revealed significant performance differences among sports (F = 4.927, p = 0.001). Each sport had unique dominant predictors: VO₂ max and anthropometry (soccer), agility (table tennis), muscle strength (weightlifting), endurance and height (basketball), and speed (karate). NSCI’s organizational analysis showed substantial deficiencies in management, facilities, and procedures (p < 0.001). Conclusion: This study confirms that BDA is crucial in advancing sustainable sports development. By identifying sport-specific performance predictors and systemic weaknesses, BDA provides a scientific foundation for designing targeted training, improving organizational quality, and building adaptive, data-driven sports ecosystems in Indonesia. The findings highlight the urgent need for national sports bodies to institutionalize BDA as part of long-term strategic planning.

Abstract

Background: Passing and crossing efficiency are recognized as key factors in football performance, yet their contextual influence in Southeast Asian competitions has been underexplored. The 2024 Mitsubishi Electric Cup offers a vital setting to examine how these technical indicators affect team tactics and rankings within the region's evolving football landscape.Aims: This study aims to analyze team distribution performance through accurate passes, pass success rates, and crossing accuracy, and to determine how these variables relate to team rankings and tactical strategies in both offensive and defensive phases.Methods: A quantitative approach was employed using descriptive statistics, Pearson correlation, and regression analysis. Data were collected from official tournament databases. The independent variables were accurate passes, pass success rate, and crossing accuracy, while team ranking served as the dependent variable.Results: Data from ten teams were analyzed. Thailand recorded the highest pass success rate (85%) and passing volume (3,373 passes), showing strong possession control. Vietnam achieved the highest crossing accuracy (60%), indicating effective wide-play. Correlation analysis revealed a moderate relationship between pass success rate and crossing accuracy (r = 0.65, p < 0.05). Regression results confirmed that pass success rate significantly predicted passing volume (R² = 0.45, p < 0.05).Conclusion: Teams with higher pass accuracy demonstrated superior control and competitive performance, while crossing efficiency was more context-dependent. Coaches and federations should emphasize structured passing drills and possession-based play, integrating crossing strategies selectively. Future studies should apply AI-assisted tactical modeling to enhance distribution and performance analysis in regional and global football

Abstract

Background: The integration of biomechanics with digital motion-analysis technologies has introduced new approaches for examining movement efficiency, kinematic characteristics, and technical patterns in walking and running activities. Kinovea, as an accessible motion-analysis software, provides both visual and quantitative feedback. However, its application in supporting technique development among beginner athletes remains insufficiently explored. Aim: This study aims to describe the use of Kinovea in biomechanics training and examine its contribution to the awareness of kinematic characteristics and movement techniques among beginner athletes. Methods: A descriptive qualitative design involved 72 beginner athletes aged 18–25 years selected through purposive sampling. Data were collected over 16 weeks through interviews, field observations, and motion video recordings analyzed using Kinovea. Kinematic data focused on joint angles, stride behavior, and movement phases during walking, running, and the flight phase. Qualitative data were analyzed using content analysis with NVivo 12, while kinematic results were interpreted descriptively to identify performance patterns and areas for technical refinement. Result: Kinematic analysis showed coordinated joint-angle patterns across all phases. Walking analysis identified arm swing angles of 50.9°–58.8° and leg separation angles of 64.3°–67.2°, indicating a stable gait rhythm. The running analysis revealed knee angles of 68.8°–69.8° and elbow angles of 87.6°–89.1°, indicating efficient propulsive mechanics. The flight phase demonstrated knee angles of 81.2°–87.8° and elbow angles of 80.4°–88.3°, suggesting effective momentum use and postural stability. These measurements supported stride-efficiency assessment and technique evaluation. Qualitative findings revealed that Kinovea enabled athletes to interpret movement phases and identify technical inefficiencies through slow-motion and frame-by-frame visualization. Conclusion: Kinovea supports basic motion analysis by providing clear kinematic information and helping beginner athletes observe and refine their movement techniques. The findings also offer practical value for coaches by enabling more precise identification of inefficient patterns and guiding targeted corrections during early-stage training.
