Journal of Coaching and Sports Science is an academic journal that aims to provide education about coaching and sports science. In this journal, theory and practice in coaching will be integrated with sports science as a critical reflection of coaching practice, as well as improving sports academics and coaches to help athletes acquire skills through sports science. The vision of this journal uncovers, understands, and develops the processes involved in sports coaching and the development of sports science.

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.
