Abstract:Modern volleyball requires complex physical capacities, particularly explosive power and match-specific endurance that are closely associated with the performance of anaerobic and aerobic energy systems. Increasing performance…
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:Physical training periodization is a scientific approach aimed at systematically regulating training load, volume, and intensity to achieve peak performance in elite athletes while minimizing the risk of injury. This study…
dy reviews 45 scientific articles published within the last ten years, covering periodization models, physiological responses to training, and the integration of technology in athlete development processes. The findings indicate that block periodization and non-linear periodization are the two most effective approaches, shown to enhance aerobic capacity by up to 10% and muscle strength by approximately 8% in high-level athletes. Additionally, the use of monitoring technologies such as Heart Rate Variability (HRV) and Global Positioning System (GPS) contributes significantly to real-time adjustments in training programs, enabling coaches to respond more accurately to athletes’ physiological conditions and prevent overtraining. However, challenges remain in implementing these technologies in sports with limited resources and due to a lack of long-term studies on the effectiveness of technology-based periodization. These findings emphasize the importance of individualized, data-driven approaches in designing training programs that not only improve performance but also sustain athletes’ careers. By integrating classical periodization principles with modern technology, training programs can be developed to be more adaptive, precise, and contextually tailored to individual needs. In conclusion, modern, responsive periodization supported by advanced technology is a crucial element in creating elite athlete development systems that are not only globally competitive but also focused on long-term health and performance.

at mempengaruhi kemampuan berkendara dan meningkatkan resiko jatuh pada lansia. Tujuan penelitian diketahuinya Pengaruh Senam Aerobic Low Impact terhadap Peningkatan Kualitas Tidur Pada Lansia di Panti Jompo Yayasan Alkautsar. Metode penelitian menggunakan eksperimen semu (Quasi Experiment) dengan metode non equivalent control group design dengan cara satu kelompok untuk eksperimen yaitu yang diberikan tindakan senam aerobic dan kelompok kontrol yaitu yang tidak diberikan senam aerobic. Populasi dalam penelitian ini adalah lansia di Panti Jompo Yayasan Alkautsar dan lansia binaan yang berjumlah 199 orang, sampel 43 orang. Teknik pengambilan sampel Purposive Sampling. Hasil Penelitian sebelum diberikan Senam Aerobic Low Impact pada lansia sebagian besar kualitas tidur ditemukan sedang, setelah diberikan Senam Aerobic Low Impact ditemukan sebagian besar lansia dengan kualitas tidur baik. uji uji Independent T Test dengan nilai p value 0,000 (p value < 0,05), yang berarti terdapat perbedaan kualitas tidur pada lansia sebelum dan setelah diberi Senam Aerobic Low Impact di Panti Jompo Yayasan Alkautsar. Simpulan Ada Pengaruh Senam Aerobic Low Impact Terhadap Peningkatan Kualitas Tidur Pada Lansia di Panti Jompo Yayasan Alkautsar. Saran untuk pihak Puskesmas sebagai pengembang Posyandu, penulis berharap program senam aerobik / senam lansia terus dilakukan secara rutin di Posyandu sebagai upaya dalam meningkatkan kualitas hidup lansia Untuk penelitian selanjutnya.
