gue and injury. This study addresses the suboptimal implementation of periodization-based microcycle planning, training load monitoring, and recovery strategies within a unified system. The objective of this research is to examine the effectiveness of an integrated training management model in improving athletes’ performance and physiological condition. A quasi-experimental method with a pretest–posttest control group design was employed, involving 40 collegiate athletes over an eight-week period. The results indicate that the experimental group showed significant improvements in countermovement jump by 12.2% and spike reach by 3.1%, accompanied by a reduction in sRPE by 11.5% and an increase in recovery scores by 22.5%, while the control group demonstrated no meaningful changes. These findings suggest that the integration of microcycle planning, internal and external load monitoring, and structured recovery strategies enhances physiological efficiency, neuromuscular adaptation, and the sustainability of athletic performance. The study concludes that the integrated training management model is more effective than conventional approaches as it enables objective and systematic control of training intensity. The novelty of this research lies in the development of an integrated training session management model that combines three key components in an applicable, practical, and context-appropriate manner for collegiate athletes, thereby bridging the gap between sport science theory and coaching practice.

rmance demands indicate that training programs alone are insufficient to produce optimal athletic performance; therefore, sports nutrition strategies become a crucial component in supporting athletes’ physiological adaptation processes. The research problem addresses how sports nutrition contributes effectively to improving the power and endurance of volleyball athletes based on recent scientific evidence. This study aims to systematically analyze the contribution of sports nutrition to enhancing the physical capacity of volleyball athletes through a scientific literature review approach. The research method employs a Systematic Literature Review (SLR) using the PRISMA framework to examine articles indexed in Scopus and SINTA published between 2015 and 2024. The identification process yielded 312 articles, followed by a rigorous screening and eligibility assessment that resulted in 22 articles meeting the inclusion criteria, with 10 core studies analyzed in depth to obtain a synthesis of relevant scientific findings. The results indicate that carbohydrate periodization of 6-8 g/kg body weight per day contributes to an improvement in vertical jump performance by approximately 3-6%, while optimal protein intake of 1.6-2.2 g/kg body weight per day increases peak power by about 4-8%. Creatine monohydrate supplementation of 3-5 g per day has been shown to enhance explosive power by 5-12%, whereas beta-alanine supplementation improves anaerobic work capacity by 8-14%. Hydration strategies and carbohydrate regulation also contribute to an increase in VO₂max by 2-5% and reduce the fatigue index by 6-10%. The findings confirm that sports nutrition functions as an essential mediator between training stimuli and the neuromuscular as well as metabolic adaptation responses of athletes. The novelty of this study lies in its conceptual synthesis that positions nutritional periodization as an evidence-based integrative strategy for sustainably optimizing the power and endurance of volleyball athletes.
Abstract:Chronic pain represents a major global health burden and often remains resistant to conventional pharmacological treatment, prompting the exploration of alternative therapeutic strategies. Electroencephalographic (EEG) neurofeedback…
eurofeedback has emerged as a non-invasive neuromodulatory intervention that enables patients to self-regulate brain activity and potentially alleviate persistent pain symptoms. This systematic review addresses the research problem of inconsistent evidence regarding the clinical efficacy and underlying mechanisms of EEG-based neurofeedback for chronic pain management in adults. A comprehensive analysis of 80 studies involving adults with chronic pain lasting at least three months was conducted, examining neurofeedback protocols, clinical pain outcomes, neurophysiological changes, secondary benefits, and methodological quality. Findings revealed heterogeneous results, with several studies reporting statistically significant and clinically meaningful pain reduction, particularly in conditions such as chemotherapy-induced neuropathy, fibromyalgia, and chronic back pain. Observed neurophysiological changes, including increased alpha power and modified connectivity in pain-related brain regions, were sometimes associated with clinical improvement, alongside reported benefits in sleep quality, mood, and overall well-being. However, evidence from sham-controlled randomized trials showed no significant differences between intervention and control groups, highlighting methodological limitations and challenges in blinding procedures. The review concludes that EEG neurofeedback is a safe and feasible intervention with potential therapeutic value for chronic pain, although current evidence remains inconsistent. The novelty of this study lies in its integrative evaluation of clinical outcomes, neurophysiological mechanisms, and protocol-specific effects, while emphasizing the need for personalized approaches, biomarker identification, and rigorous experimental designs to clarify efficacy and optimize treatment implementation.

parents. This condition poses risks to physical health, emotional well-being, and overall infant development. This study aims to analyze the effect of baby massage on sleep quality among infants aged 3-6 months at Babycare Bondowoso and to identify differences in sleep quality before and after the intervention. The study employed a quantitative approach with a quasi-experimental one-group pretest-posttest design involving 40 infants selected through total sampling. Data were collected using questionnaires and observation sheets, then analyzed using the Wilcoxon test. The results showed that prior to the intervention, 87.5% of infants experienced poor sleep quality, whereas after the intervention, all infants (100%) demonstrated improvement to good sleep quality. Statistical analysis indicated a p-value of 0.00, which is lower than 0.05, confirming a significant effect of baby massage on infant sleep quality. These findings demonstrate that baby massage effectively improves sleep duration, comfort, and stability through physiological relaxation mechanisms. The novelty of this study lies in providing empirical evidence of the effectiveness of baby massage as a non-pharmacological intervention that is simple, safe, and can be independently applied by parents while offering holistic benefits for infants. The findings are expected to serve as a basis for developing health education and improving infant care practices.

low ability to recognize, understand, and manage emotions adaptively, highlighting the need for effective strategies to enhance emotional awareness. This research investigates the effectiveness of self-reflection and journaling in improving students’ mood awareness. A combination of descriptive qualitative and quasi-experimental pretest-posttest designs was used, with instruments including mood scales, reflection guidelines, and students’ daily journals. Results showed a 32% increase in the average mood awareness score, a decrease in students with low awareness from 64% to 18%, and an increase in high awareness from 14% to 56%. Active participation was observed in 78% of students, while 85% consistently documented their emotional experiences, 88% reported feeling relieved, and 76% could identify recurring emotional patterns. The intervention also promoted the development of more adaptive self-regulation strategies, such as time management, adequate rest, and social support, increasing from 21% before the intervention to 69% afterward. Sustainability of practice was indicated by 61% of students intending to continue journaling independently and 57% integrating it into their daily routines. The novelty of this study lies in the integration of self-reflection and journaling as a practical, systematic, and sustainable approach to enhance emotional awareness and psychological well-being. The findings confirm that a simple yet structured intervention can create significant improvements in emotion management and adaptive behaviors among students.

The novelty of this study lies in strengthening empirical evidence on the effectiveness of Android-based digital learning materials in a cross-regional distance education context, while also providing practical contributions to the development of digital learning strategies aimed at enhancing the learning motivation of Universitas Terbuka students.
Abstract:The development of digital technology over the past two decades has revolutionized human communication, social interaction, and the formation of both individual and collective identities in a global context. Digital media…
a no longer merely function as communication tools but have become socio-cultural spaces that actively shape values, norms, symbols, and everyday practices. This phenomenon raises research questions regarding how cultural transformation and identity construction are influenced by the dominance of digital technology, as well as how social media and platform algorithms shape cultural visibility and digital identities. This study employs a qualitative approach through a critical narrative literature review, synthesizing theories of network society, mediatization, cultural globalization, digital capitalism, and digital identity. The analysis focuses on four key issues: cultural digitalization, the role of social media in identity formation, the emergence of hybrid identities, and platform power in determining cultural representation. Findings indicate that digital technology has ambivalent effects: it expands spaces for cultural expression, enhances public participation, and provides opportunities for marginalized groups to represent their identities; however, global platform dominance drives cultural homogenization, identity commodification, and inequitable symbolic representation. The novelty of this study lies in integrating a critical perspective on the influence of algorithms and digital capitalism in identity formation, which has rarely been addressed comprehensively in digital cultural studies. These findings offer theoretical contributions to media and cultural research as well as practical implications for understanding identity representation in the global digital era.
Abstract:Stunting is a chronic nutritional problem that occurs as a result of prolonged inadequate nutrient intake, beginning as early as the prenatal period, and leading to impaired physical growth and cognitive development in children.…
hildren. This condition remains a strategic public health issue because it has direct implications for the quality of human resources and national competitiveness in the future. This study focuses on the role of the family, particularly pregnant women and breastfeeding mothers, in preventing stunting through adequate nutritional fulfillment during the first 1,000 days of life, with an emphasis on exclusive breastfeeding practices. The method employed is a conceptual review based on scientific literature and relevant health policies to analyze the relationship between early nutritional adequacy and the risk of stunting in children. The findings indicate that stunting not only results in children having a height below the age-standard norm, but also disrupts brain development, which in turn affects learning ability, productivity, creativity, and children’s readiness to face future educational and social challenges. Family-based approaches to stunting prevention have proven effective, as the family represents the primary and earliest environment for meeting children’s nutritional needs. Exclusive breastfeeding during the first six months of life emerges as a key strategy, as it optimally fulfills infants’ nutritional requirements and reduces the risk of malnutrition. The conclusion of this study emphasizes that strengthening the role of the family through nutritional education for pregnant and breastfeeding mothers is a strategic step toward sustainable stunting prevention. The novelty of this scientific work lies in its integrative emphasis on family-based approaches and the optimization of exclusive breastfeeding as a foundation for improving human resource quality from early life, encompassing not only physical, but also cognitive, emotional, and social dimensions of child development.
