Abstract

Background: The application of game models in badminton for young athletes is considered very appropriate. Game models incorporate training elements suitable for young athletes, who are still in a developmental stage that requires play, so that training can be maximized, as athletes feel more relaxed and have more fun in the program. Aims: The research aims to examine the effectiveness of the game model in improving young athletes' badminton skills. Methods: This study used a quantitative descriptive quasi-experimental design. The research design used in this study was “The One Group Pretest Posttest Design” with no control group. Results: The Wilcoxon test in Table 3 above shows that the pretest and posttest scores for badminton skills were significantly different (p < 0.05). Thus, the game model is efficacious in improving athletes' badminton skills. Conclusion: The game model applied in this study demonstrates high effectiveness in improving young athletes' badminton skills. Therefore, the researcher recommends using a game-based training model to improve young athletes' badminton skills. Implementing game-based training models can significantly enhance the development of young badminton athletes. By integrating play-oriented activities into training, coaches can create a more engaging and motivating environment that aligns with children's developmental needs. This approach not only improves technical and tactical skills in badminton but also promotes enjoyment, reduces training stress, and fosters long-term athlete participation.

Abstract

Background: This study examined the level of mindfulness and its relationship with psychological well-being among gifted student-athletes in Jordan, in light of the growing interest in the psychological role of mindfulness in supporting academic and athletic performance, as well as emotional balance, among this population. Aims: The study aimed to identify levels of mindfulness and psychological well-being among gifted student-athletes, to explore the nature of the relationship between these two variables, and to examine whether statistically significant differences in psychological well-being exist by gender. Methods: The study sample consisted of 145 male and female gifted student-athletes, selected using simple random sampling. Ryff’s Psychological Well-Being Scale – Short Form was employed. Data were analyzed using appropriate statistical methods, including means and standard deviations, tests of difference, and correlation coefficients. Results: The findings indicated moderate levels of mindfulness (M = 3.22, SD = 0.35) and psychological well-being (M = 3.17, SD = 0.54). No statistically significant gender differences in psychological well-being were found (p > 0.05). In contrast, a strong, positive, and statistically significant correlation was identified between mindfulness and psychological well-being. Conclusion: The results highlight the practical value of integrating mindfulness-based training programs within educational and athletic environments for gifted students, as these programs enhance emotional balance, psychological resilience, and athletic performance. The study also provides a theoretical contribution by clarifying the relationship between mindfulness and psychological well-being within the Arab context, thereby supporting the development of evidence-based educational and athletic practices.

Abstract

Background: Rural areas face persistent challenges in promoting regular sports participation due to demographic ageing, limited infrastructure, and uneven access to organized programs. These constraints may affect not only population-level physical activity but also the training environments available to athletes and coaches in small rural municipalities. Aims: This study analyzes sports habits, motivations, barriers, and the availability of sports facilities in three rural municipalities in southern Spain, examining how local infrastructural and organizational conditions shape participation patterns and adherence to sport. Methods: A cross-sectional descriptive design was employed involving 289 residents from Cumbres Mayores, Cumbres de San Bartolomé, and Cumbres de Enmedio, selected through a non-probabilistic snowball sampling technique. Data were collected using an adapted questionnaire based on the Spanish Survey of Sports Habits, consisting of items on sports participation frequency, motivations, perceived barriers, and assessment of local sports facilities. The questionnaire demonstrated adequate content validity through expert judgment and high internal reliability (Cronbach’s α = 0.86). Data were analyzed using descriptive and comparative statistical procedures, including frequencies and percentages, to identify inter-municipal patterns. Result: The findings reveal apparent inter-municipal differences in sustained sports participation and perceived facility adequacy. More than one-third of respondents reported not engaging in regular physical activity, while insufficient or poorly maintained facilities were identified as a key barrier by over 30% of inactive participants. Approximately 40% indicated having practiced sport in the past but no longer do so, particularly in the smallest municipality, suggesting adherence challenges rather than a lack of initial interest. Gender-related disparities were also observed, mainly associated with time constraints and limited program availability among women. Notably, over 70% of participants expressed willingness to resume or increase participation if access to facilities and guided programs improved. Conclusion: Sports participation in small rural contexts depends not only on individual motivation but also on the availability, accessibility, and activation of local sports infrastructure. For athletes and coaches, these conditions directly affect training continuity, program viability, and development opportunities. The results support the need for context-sensitive sports planning that integrates infrastructure improvement, supervised training, and community engagement to promote sustainable training environments in rural areas.

Abstract

Background: Emotional management is a key psychological factor influencing futsal performance, but available measurement instruments are still general in nature, lack sport-specific validation, and have not been tested on Indonesian futsal athletes. Aims: This study seeks to rigorously validate and confirm the factor structure of an emotional management instrument designed explicitly for Indonesian futsal athletes, thereby strengthening its scientific and contextual relevance calculations with CFA. Methods:  Confirmatory Factor Analysis (CFA) was performed on data from 438 athletes recruited through incidental sampling across multiple regions in Indonesia. The emotional management instrument comprised 23 items that had previously undergone rigorous content validation by experts, including psychologists, national-level futsal coaches, and sport science academics. Model fit indices, convergent validity, and internal consistency reliability were systematically evaluated to ensure the robustness of the measurement model. Results: The five-factor model demonstrated excellent fit to the data (e.g., CFI > .95, TLI > .95, RMSEA < .06, SRMR < .08). All factors had AVEs above 0.50, indicating strong convergent validity. Reliability indices were high, with McDonald's ω and Cronbach's α exceeding .70 for all factors. Conclusion: The results indicate that the emotional management instrument demonstrates satisfactory validity, reliability, and structural integrity for application among Indonesian futsal athletes, thereby providing a robust framework for psychological assessment and supporting future research, talent development, and mental training programs.

Abstract

Background: Plyometric and weight training are prevalent strategies for enhancing body composition, explosive strength, and running speed, all of which are crucial for physical performance and health. Nonetheless, their comparative efficacy remains contested, particularly among non-athletic groups. Aims: This study investigated and compared the effects of an 8-week plyometric and weight-training program on body composition index (BMI), explosive performance, and running speed among twenty-eight male student-athletes. Methods: The design was selected to determine causality and directly compare the effectiveness of two different training modalities under controlled conditions. To improve scientific rigor, the randomization process, assessor blinding, and meticulous control of training parameters. Result: Both training methods yielded substantial improvements across all evaluated variables. Plyometric training resulted in significant enhancements in horizontal explosive performance, evidenced by standing long jump results (p = 0.026), as well as moderate improvements in sprint speed. Conversely, weight training produced more significant enhancements in vertical jump performance (p = 0.038) and power output (p = 0.012). Both groups exhibited substantial decreases in body mass index and body fat percentage (p < 0.001). Conclusion: These data indicate that both plyometric and weight training significantly improve physical fitness. Plyometric training primarily enhances horizontal explosive power and sprint performance, whereas weight training is more effective for improving vertical power-related outcomes.

Abstract

Background: Female physical performance can be influenced by perceived, physiological, and physical factors, making it an important field for further research. Aims: The purpose of this study was to analyze the effects of the menstrual cycle (MC) on the cardiovascular and neuromuscular load of amateur women athletes in CrossFit® during real training situations. Methods: Resistance-trained CrossFit® athletes (without oral contraception) and eumenorrheic women participated in this study (age: 29.6 ± 4.06 years; height: 1.59.3 ± 0.06 m; body mass: 61.22 ± 4.59 kg). A cross-sectional, descriptive study was conducted to evaluate heart rate variability (rMSSD), upper-body strength, muscular endurance, and power performance. The data were analyzed using a one-way repeated-measures ANOVA and the nonparametric Friedman test to assess significant differences among the follicular, ovulatory, and luteal phases for all assessments. The significance was set at p ≤ 0.05. Result: Results revealed no significant differences between the menstrual cycle phases in performance: (HRV RMSSD: H: 0.830, p: 0.443, η2: 0.038), (Push up test: H: 0.041, p: 0.959, η2: 0.002), (countermovement jump: H: 11.921, p: 0.050, η2: 0.362), (rate force development CMJ: H: 1.242, p: 0.299, η2: 0.056), (squat jump: H: 0.439, p: 0.648, η2: 0.020), (rate force development SJ: H: 1.703, p: 0.194, η2: 0.075), (isometric mid-thigh pull: H: 0.019, p: 0.981, η2: 9.132x10-4). Performance is not altered during the MC in female CrossFit® trained athletes. Conclusion: These findings demonstrate that the menstrual cycle does not significantly influence internal and external training load, heart rate variability, or strength and power performance in this population.

Abstract

Background: Girls with mild intellectual disability experience persistent deficits in adaptive behavior, coping skills, and social integration, particularly during adolescence when psychosocial demands intensify. Despite this need, accessible, school-based psychological interventions remain limited. Given the risk of long-term social exclusion and reduced quality of life, identifying low-cost, inclusive strategies such as unified rhythmic activity is urgently required. Aims: This study evaluated the effects of rhythmic activity training and unified rhythmic activity training on psychological outcomes, adaptive behavior, and coping strategies for girls with MID, who participated alongside typically developing peers. Methods: A three-arm randomized controlled trial included 45 girls (10–14 years) with mild intellectual disability (IQ 50–70) in Coimbatore, India. Participants were assigned to rhythmic training, unified rhythmic training, or control groups. Interventions lasted 12 weeks (60 minutes, thrice weekly). Primary outcomes were adaptive behavior and coping strategies; secondary outcomes included self-efficacy, social competence, emotional regulation, quality of life, and behavioral problems. Analyses applied intention-to-treat, repeated measures ANOVA, and ANCOVA. Result: Significant within-group reductions were found for Irritability/Agitation in RATG and URATG (both p < 0.001), but not in CG (p = 0.64), with significant between-group differences (p < 0.001). Social Withdrawal improved in RATG (p = 0.003) and URATG (p < 0.001), not in CG (p = 0.81). Stereotypic Behavior and Hyperactivity decreased significantly in both intervention groups (p ≤ 0.009), but not in CG (p ≥ 0.75), with significant group effects (p < 0.001). Inappropriate Speech showed no within-group significance, though between-group differences were significant (p = 0.001). Conclusion: This study establishes that rhythmic and unified rhythmic interventions significantly enhance adaptive behavior and coping in girls with mild intellectual disability, with the unified model offering superior social benefits. It advances inclusive physical activity as a theoretically grounded, evidence-based approach and contributes robust experimental data supporting scalable, school-based psychosocial interventions.

Abstract

Background: Body proportions and muscular development are closely linked to force production capacity, yet their application as predictive tools in Olympic weightlifting training and athlete selection remains insufficiently explored. Aims: The study aimed to quantify the relationships between specific relative indexes of body muscularity and maximal force generated during two classic multi-joint resistance exercises – the back squat and the clean and jerk deadlift. Methods: 17 athletes participated in the study, all of whom were national-level competitors. Linear regression equations were estimated between four relative body muscularity parameters (Height/Body mass3 (BMH), Height/Shin circumference (HS), Height/Thigh circumference (HT), Height/Arm circumference (HA), and Height/Chest circumference (HC)) and maximal strength in back squat and clean and jerk deadlift. Results: We calculated statistically significant Pearson correlation coefficients and linear regression coefficients between the studied relative body muscularity parameters and maximal muscle strength in the back squat and deadlift. The adjusted R-squared values ranged from 0.082 to 0.768 across the regression equations. Conclusion: All studied relative parameters were statistically significant predictors of maximal strength in the deadlift and squat, with only 3 exceptions (BMH for the deadlift and BMH and HS for the squat). These results (in conjunction with the high adjusted R-squared values of the regressions) indicate that the constructed statistical models explain a relatively high proportion of the variation in the results. These findings can be used in training practice as guidelines for anthropometric changes to improve sports performance.

Abstract

Background: Assessing athletic qualities, coach training, and sports infrastructure can influence athletic performance. This study examines the link between the swimmer’s athletic profile test and the role of athletic quality assessment in optimizing performance. Aims: To study the role of athletic quality assessment among Moroccan coaches and technical directors in the physical preparation of their swimmers, in relation to sports infrastructure. Method: twenty elite swimmers of both sexes, aged 14 to 16, and 33 coaches and technical directors participated in this study. An athletic profile assessment test was conducted, and a survey was conducted on the role of athletic quality assessment across various aspects, including training, athletic quality assessment, and constraints related to sports infrastructure. Chi-square and independence correlation tests were used to analyze the significance and correlation between variables. Results: The swimmers’ athletic profile tests were exploratory. No significant difference was found between participants’ training and their physical preparation practices for training (p = 0.085 > 0.05). No significant difference was found between participants’ status and the location of their physical preparation (p = 0.939). No significant correlation was found between the importance of the assessment and participants’ gender in the Mann-Whitney test (46 with exact; p = 0.540 > 0,05). Conclusion: Our results suggest that implementing athletic profile testing for swimmers can be useful for selecting and customizing training programs and improving performance in specific disciplines. Our findings indicate that the importance of physical preparation is not linked to coach training or to constraints on sports infrastructure.
