Abstract

Background: Basketball performance requires integrating multiple physical components, including strength, speed, agility, flexibility, and endurance. However, conventional training programs often emphasize isolated components, limiting optimal performance development. An integrated training approach is therefore needed to address the multidimensional physical demands of basketball. Aims: Evaluate the effectiveness of an Integrated Physical Training (IPT) program in improving overall physical performance in basketball players, focusing on key components: strength, speed, agility, flexibility, and endurance. Methods: A quasi-experimental pre-test–post-test control group design was employed. Twenty-four male basketball players were randomly assigned to an experimental group and a control group. The intervention was conducted over 12 sessions (three sessions per week). Physical performance was assessed using a standardized fitness test battery covering strength, speed, agility, flexibility, and endurance. Data were analyzed using inferential statistics and effect size (Cohen’s d). Result: The IPT group demonstrated significant improvements (p < 0.05) across all physical performance variables compared to the control group. Effect sizes ranged from large to very large (Cohen’s d= 1.26–3.00), indicating substantial multidimensional performance gains. Conclusion: Integrated Physical Training (IPT) is more effective than conventional training in improving overall physical performance in basketball players. This approach is recommended as a comprehensive training model to optimize sport-specific physical adaptations.

Abstract

Background: Altitude training is widely used to improve endurance performance through hematological adaptations, but inter-individual variability is substantial, and responses among Southeast Asian athletes are poorly documented. Aims: This study compared hemoglobin, hematocrit, and reticulocyte dynamics in Indonesian elite rowers undergoing continuous high-altitude (HA) versus intermittent Pangalengan (PGL) protocols to characterize temporal adaptation patterns, identify predictive biomarkers, and inform protocol optimization. Methods: A total of 23 national-team rowers (8 females, 15 males) completed a 33-day longitudinal observational study at 2,434 m. Blood samples were collected at baseline (T0), post-exposure (T1, day 22), and recovery (T2, day 31). The HA group (n=12) remained continuously at altitude; the PGL group (n=11) made periodic normoxic descents. Data were analyzed using mixed-model repeated-measures ANOVA and correlation analyses. Ethical approval was obtained before data collection in accordance with the Declaration of Helsinki. Results: Contrary to expectations, the HA protocol produced significant hemoglobin reductions (males: −3.78%, p=0.008), whereas the PGL protocol elicited positive adaptations (males: +4.69%, p=0.026). Negative responders constituted 75% of the HA group versus 9.1% of the PGL group (χ²=11.52, p=0.003). Baseline ferritin did not predict hemoglobin responses (r=−0.122, p=0.579). Conclusion: Protocol design, particularly the inclusion of normoxic recovery periods, was a stronger determinant of hematological adaptation than individual iron stores or sex. These findings affirm the live-high-train-low principles across diverse populations and support recovery-oriented protocols for Indonesian elite rowers.

Abstract

Background: Psychological responses to sport injury critically determine rehabilitation engagement and return-to-sport outcomes. Existing research has predominantly employed variable-centered approaches that obscure heterogeneity in athletes' psychological adaptation, particularly within culturally embedded combat sports such as Pencak Silat. Aims: This study aimed to identify distinct psychological profiles among injured Pencak Silat athletes empirically and to examine how these profiles relate to rehabilitation readiness, thereby advancing an evidence-based framework for psychological skills training in injury rehabilitation contexts. Methods: A quasi-experimental pretest–posttest design combined with a person-centered analytical framework was employed. Data were collected from 108 injured Pencak Silat athletes across nine secondary educational institutions. Latent Profile Analysis (LPA) was conducted on five psychological domains: anxiety regulation, coping skills, self-confidence, motivation, and rehabilitation readiness, followed by MANOVA and hierarchical regression to examine profile-based differences and predictive relationships. Results: Three distinct profiles, Vulnerable (n = 29), Adaptive (n = 46), and Resilient (n = 33), were identified. All psychological indicators differed significantly across profiles, with large effect sizes. Hierarchical regression demonstrated that psychological skills and profile membership accounted for significant variance in rehabilitation readiness beyond injury-related factors (ΔR² = .19). Conclusion: Psychological adaptation to sport injury is best conceptualized through profile-based configurations of psychological skills. These findings support the development of individualized, profile-informed psychological skills training to enhance rehabilitation readiness and sustainable return-to-sport outcomes in Pencak Silat athletes.

Abstract

Background: Inline speed skating demands explosive strength and specific anthropometric profiles, yet studies on sex-based morphological and functional differences among Latin American skaters are scarce. This exploratory cross-sectional study aimed to characterize physical performance and anthropometric variables by sex in elite Colombian junior inline speed skaters. Aims: The primary objective of this exploratory cross-sectional study was to characterize the anthropometric profiles and physical performance variables by sex in a sample of elite Colombian junior inline speed skaters. Methods: Twenty-three elite skaters (12 females, 11 males; aged 16-21 years) were assessed. Anthropometric profiling followed ISAK guidelines, measuring skinfolds, girths, and breadths. Physical performance and explosive strength were evaluated using various jump tests (SJ, CMJ, SLCMJ, and continuous jumps) via the My Jump Lab application. Results: Marked sexual dimorphism was observed in body composition: females exhibited higher subcutaneous adiposity (fat mass), whereas males demonstrated greater muscle mass and skeletal robustness. However, differences in explosive performance and functional metrics between sexes were unexpectedly modest. Conclusions: Elite female skaters achieve functional outcomes comparable to those of males despite marked morphological differences. These findings indicate that higher body fat limits jumping capacity, highlighting the need for systematic body composition monitoring and the development of sex-specific training strategies.

Abstract

Background: Despite the complex physiological, technical, and mechanical demands of Sanda Wushu, athlete monitoring still relies largely on subjective coach observation and self-report. A feasible, objective, and coach-interpretable field-testing framework is therefore needed to detect performance changes and inter-limb asymmetry before integrating more complex wearable-sensor technologies. Aims: To examine the feasibility, responsiveness, and descriptive asymmetry-monitoring value of a standardized multi-domain field-test battery administered across a full training squad of Sanda Wushu athletes. Methods: An observational, field-based, repeated-measures monitoring study involved 72 nationally competing athletes (36 males and 36 females; age 18–30 years, M = 24.2, SD = 3.7). The battery was administered in July (Session 1) and October 2025 (Session 2). Valid results were benchmark-normalized to a composite Performance Index (PerfIndex, 0–1 scale; higher = better) and a categorical Score Index (ScoreIndex, 1–5 ordinal scale; higher = better). Inter-limb asymmetry (%) was computed for SL Wall Sit and Triple Hop Jump. Paired t-tests were reported with 95% CIs, Cohen's dz, Hedges' g, and a sensitivity analysis excluding four athletes with block-missing Session 1 items. Results: PerfIndex increased significantly from 0.727 ± 0.031 to 0.755 ± 0.033, mean difference +0.029, 95% CI [0.024, 0.034], t(71) = 11.46, p < .001, dz = 1.35, Hedges' g = 1.34. ScoreIndex showed the same pattern (2.92 ± 0.25 to 3.16 ± 0.26; t(71) = 9.41, p < .001, dz = 1.11, Hedges' g = 1.10). SL Wall Sit asymmetry increased slightly but significantly (27.9% to 30.9%, p = .023, dz = 0.28); Triple Hop asymmetry did not change significantly (11.5% to 11.7%, p = .718). Asymmetry values above the descriptive 15% reference zone were observed in a substantial share of the squad at both sessions. Conclusion: The field-test monitoring framework was feasible for squad-level implementation and detected small-to-moderate improvements in composite performance across two sessions. Inter-limb asymmetry screening also identified athletes requiring further assessment, although the findings should be interpreted as monitoring signals rather than diagnostic indicators.

Abstract

Background: Aerobic capacity (VO₂max) is a critical determinant of basketball performance due to the sport’s intermittent high-intensity demands. Although circuit training and interval training are widely used to improve aerobic fitness, limited evidence exists regarding the role of Body Mass Index (BMI) in moderating training outcomes among adolescent basketball athletes. Aims: This study aimed to examine the effects of training method (circuit vs. interval) and BMI category on VO₂max in adolescent basketball athletes, as well as the interaction between these variables. Methods: A 2×2 factorial experimental design was employed involving 40 basketball athletes aged 15–18 years. Participants were allocated to four groups based on training method (interval or circuit) and BMI category (low or high). VO₂max was assessed using the Beep Test, while BMI was calculated from height and weight measurements. Data were analyzed using two-way ANOVA at a significance level of 0.05. Result: No significant difference was found between interval and circuit training in VO₂max outcomes (p = 0.362), indicating that both methods produced comparable aerobic adaptations. A significant difference was observed between BMI categories (p = 0.036), with athletes in the low-BMI group demonstrating higher VO₂max values than those in the high-BMI group. No significant interaction between training method and BMI category was found (p = 0.685). Conclusion: Both interval and circuit training effectively improved VO₂max in adolescent basketball athletes. Nevertheless, BMI significantly affected the magnitude of improvement, suggesting that maintaining an optimal BMI may support better aerobic adaptation in youth basketball training programs.

Abstract

Background: Athletic mental energy is an important sport-specific psychological resource that supports athletes’ motivation, focus, confidence, and readiness during training and competition. However, its social and psychological correlates remain underexamined in regional collegiate sport contexts in the Philippines. Aims: This study examined the statistical associations among received social support, burnout, and athletic mental energy among collegiate student-athletes in Region XI, Philippines, and tested burnout as a possible indirect pathway between received social support and athletic mental energy. Methods: A quantitative, non-experimental correlational design with mediation analysis was employed. Participants were 280 collegiate student-athletes selected through systematic random sampling. Data were gathered using the Athletes’ Received Support Questionnaire, Athlete Burnout Questionnaire, and Athletic Mental Energy Scale. Mediation analysis was conducted using Hayes’ PROCESS macro Model 4 in SPSS with 5,000 bootstrap resamples. Result: Received social support was significantly and positively associated with athletic mental energy (B = 0.123, p = .009). Burnout was not significantly associated with athletic mental energy (p = .061), and the indirect pathway through burnout was not significant. Conclusion: The findings suggest that received social support is directly associated with higher athletic mental energy among collegiate student-athletes, while burnout did not statistically explain this association. Strengthening responsive support systems may help sustain athletes’ psychological readiness in collegiate sport settings.

Abstract

Background: Adolescence at 16 years is a critical stage for developing agility, flexibility, and coordination in football players. Globally, many adolescents fail to meet recommended physical activity levels, and organized sports participation often declines due to burnout and low engagement. Structured recreational training can enhance motor skill development while fostering motivation, engagement, and psychosocial growthAim: This study aims to implement a guided recreational training program specifically designed to enhance agility, flexibility, and coordination in 16-year-old youth football players in Iraq, addressing the research gap related to the limited availability of multi-component programs in resource-constrained settingsMethods: Forty-eight male football players were randomly assigned to an experimental group (n = 20) and a control group (n = 20), with a pilot group of eight participants used to refine testing instruments. Over 12 weeks, the experimental group completed 24 recreation-based sessions (2 sessions/week, 1 hour each), while controls followed regular training. Agility, flexibility, and coordination were assessed pre- and post-intervention, and regression analysis examined program effects.Result: The experimental group showed significant improvements over controls in all variables: agility (t = -39.920, p < 0.001), flexibility (t = 24.724, p < 0.001), and coordination (t = -26.726, p < 0.001). Regression analysis indicated no significant effect of pre-test scores on agility and coordination, while flexibility had a modest predictive effect (B = 0.217, p = 0.040).Conclusion: Guided recreation-based training effectively sustained motivation and engagement, enhancing acquisition and application of motor skills. Integrating structured recreational components into adolescent football programs can overcome limitations of conventional methods, promoting skill diversity, stronger motivation, and enjoyable learning experiences.

Abstract

Background: Spatial cognitive skills, encompassing bilateral distance estimation, multi-object positional reasoning, angular spatial judgment, and navigational planning, are primary determinants of shooting performance in precision sports such as pétanque, yet no validated sport-specific instrument exists to measure these capacities in this athletic population. Aims: This study aimed to develop and validate a spatial cognitive skills instrument for elite pétanque athletes through a systematic Research and Development (R&D) approach, encompassing expert panel content validity evaluation and field effectiveness testing. Methods: An R&D design was employed across four sequential phases: preparation (systematic needs analysis and construct identification via focus group discussion), development (construction of a 15-item five-level motor-perceptual board apparatus instrument), content validation (Aiken’s V evaluation by a six-member multi-disciplinary expert panel), and field effectiveness testing (instrument administration to 57 senior pétanque Indonesian athletes, 40 males and 17 females, aged ≥ 17 years). Aiken’s V ≥ 0.75 was set as the content validity threshold. Effectiveness testing examined score distributions, difficulty gradient verification, and preliminary discriminant validity between athlete experience groups. Results: Validation by four psychologists showed that 13 items met acceptable standards, with Aiken values ranging from 0.8 to 0.9. However, two items did not meet the standards: items 7 (V = 0.70) and 14 (V = 0.65). This lower validity was also reinforced by qualitative feedback from the validators, who recommended refining the instrument's measurement range and questioned its consistency. Furthermore, validation by pétanque coaches yielded an Aiken value of 0.9, indicating satisfactory content validity. Finally, experts in sports testing and measurement also reported satisfactory results. Conclusion: The instrument demonstrated acceptable content validity for 13 of 15 items and promising field effectiveness, establishing a theoretically grounded and sport-specific Phase 1 psychometric foundation. Items 7 and 14 require targeted revision before reliability assessment, construct validity testing, and normative data development in subsequent phases.

Abstract

Background: Pointing accuracy is a central performance skill in petanque because successful pointing determines boule proximity to the jack and shapes scoring opportunities during match play. However, conventional university practice often emphasises isolated technical repetition, whereas competition requires accuracy under time, peer, and outcome pressure. Purpose: This study compared Team Competition-Based Training (TCBT) with Standard Training (ST) for improving petanque pointing accuracy among university athletes. Methods: A course-based quasi-experimental pretest-posttest control-group design was implemented with 50 students. Participants were allocated to TCBT (n = 25) or ST (n = 25). Both groups completed 16 structured sessions over eight weeks. The technical content, duration, equipment, and training frequency were matched; only the organisational format differed. Pointing accuracy was measured at 6 m using a 0-15 scoring protocol. Results: Both groups improved significantly from pre-test to post-test. The TCBT group improved from 2.32 +/- 1.35 to 7.40 +/- 1.47, whereas the ST group improved from 2.24 +/- 1.30 to 6.20 +/- 1.38. The post-test between-group difference favoured TCBT, t(48) = 2.969, p = .005, mean difference = 1.20 points, 95% CI [0.39, 2.01], Cohen's d = 0.84. Conclusion: Within the limits of a single-university sample and an immediate post-test design, TCBT produced greater short-term improvement in pointing accuracy than ST. The findings support the cautious integration of competition-like team formats into university petanque training.
