Background: Research on the application of technology in sports in Romania is completely lacking, and the existing studies at the international level have mainly been carried out in recent years. We considered it appropriate to highlight the best practice models of technology application in sports that can be multiplied, adapted, improved, and widely used. The paper aims to identify the use of technology and devices in sports, with an emphasis on their role in training and competitions with the aim of improving sports performance, to provide sports specialists, organizations, and authorities with a wide range of information regarding the connection between sport and technology. The results obtained regarding the application of technology in sports refer mainly to the following: techniques and technologies used in training and competition (portable localization technology and global positioning systems (GPS); Virtual Reality (VR) technology; video analysis; digital technologies integrated into sports training); aspects of sports training targeted through the use of technology (use of technology for athlete health, recovery, and injury management; use of technology for monitoring sports performance and various body indicators); training optimization and ecological dynamics and the sustainable development of sports. Conclusions: Unitary research, at a European or even global level, in a uniform theoretical and practical framework, could lead to much more efficient training with large increases in sports performance. The coaches and specialists working with the athlete determine the specificity of some elements of the training, depending on the characteristics of each athlete. Large clubs could become a factor in generating and disseminating knowledge related to training and competition monitoring, sports performance enhancement, and health, recovery, and injury management. Research directions for the use of technology in sport and the formation of connections with other fields can be extended. For example, combined technologies assisted by specialized software can be used. Creativity must be the starting point for the use and combination of existing technologies in sports and for the creation of new ones. Their creation and use involve the teamwork of athletes, coaches, and specialists from different fields, such as sports, physiology, psychology, biomechanics, informatics, etc.

The revalorization of food processing by-products represents a critical strategy for enhancing resource efficiency and advancing circularity within the food system. This review examines the potential of three major plant-based agro-industrial by-products—fruit and vegetable residues, brewer’s spent grain, and spent coffee grounds—as sources of high-value functional ingredients. These by-products contain bioactive compounds, including dietary fibers, polyphenols, proteins, peptides, oils, and antioxidants, that can be recovered using emerging green extraction and bioprocessing technologies. Conventional extraction methods are progressively being replaced or hybridized with enzyme-assisted, ultrasound-assisted, microwave-assisted, and deep eutectic solvent techniques to improve yield, reduce solvent consumption, and preserve bioactivity. The recovered compounds have demonstrated promising applications as gelling agents (pectin), natural colorants and antioxidants, protein-enriched flours, prebiotic fibers, and bioactive extracts for functional food and nutraceutical formulations. However, challenges persist in standardizing feedstock composition, scaling continuous extraction processes, ensuring safety and regulatory compliance, and generating robust techno-economic and life-cycle assessments to validate sustainability claims. This review synthesizes biochemical composition data, processing pathways, food applications, and regulatory considerations, and identifies research priorities for developing integrated, scalable biorefinery models that valorize food by-products into market-ready functional ingredients.

The scourge of food waste (FW) is a significant global challenge, impacting climate change, food security, and the sustainability of agrifood systems. The objective of this paper is to identify, analyze, and understand the factors influencing household consumer behaviors in Romania regarding the reduction of FW. Three primary research objectives were established to assess food consumption behaviors within households, to explore attitudes toward FW, and to understand the motivations for reducing FW along with the measures implemented by households to address this issue. Methodology: Data were collected through an online self-administered questionnaire, designed to investigate consumer behaviors related to the avoidance of FW. A descriptive statistical analysis was performed, and a linear regression model was developed to evaluate a composite index measuring Romanian consumers’ behavior towards FW reduction. Results: The resulting model identifies key predictors that drive concrete actions to minimize FW, including the desire to mitigate the environmental impact, household conversations about FW and strategies to reduce it, established food routines, the influence of one’s social circle, individual ecological and social responsibility, and the effectiveness of awareness campaigns addressing the consequences of FW. Practical and social implications: The findings highlight the necessity of education and awareness initiatives to shift attitudes and behaviors concerning FW. Future research is warranted to deepen understanding and enhance interventions. Originality: This study represents a pioneering and innovative inquiry into FW behavior in Romania, filling a gap in the existing literature and contributing to the broader discourse on this pressing environmental issue.

Background: Combat sports require athletes to repeatedly perform explosive actions under conditions of fatigue, demanding high levels of neuromuscular coordination, reactive agility, and intermittent effort capacity. This study examined changes in biomechanical and neuromuscular performance over a 15-week period during which competitive Sambo athletes completed a CrossFit-based functional training program alongside their regular sport-specific training. Methods: Forty male Sambo athletes (22.4 ± 2.6 years) completed a longitudinal repeated-measures intervention consisting of three weekly CrossFit-based sessions integrated into regular sport-specific training. The program was periodized across four progressive mesocycles emphasizing functional strength, explosive power, reactive agility, and fatigue resistance. Pre- and post-intervention assessments included upper- and lower-limb reaction speed, vertical jump height, repeated jump endurance, reactive agility, grip endurance, body-weight squat performance, Romanian deadlift repetitions, and the Special Judo Fitness Test (SJFT). Statistical analyses included paired-samples t-tests or Wilcoxon signed-rank tests with Benjamini–Hochberg false discovery rate correction (α = 0.05). Results: Significant post-intervention improvements were observed in most performance variables. Upper- and lower-limb reaction performance improved by 22.9% and 9.7%, respectively (p < 0.001), while vertical jump height increased by 11.4% and repeated jump endurance by 16.6% (p < 0.001). Reactive agility time decreased by 6.6% (p < 0.001), indicating faster cognitive-motor responsiveness. Functional strength improved substantially, with increases of 43.7% in body-weight squat performance and 71.9% in Romanian deadlift repetitions (p ≤ 0.001). Grip endurance improved by 6.3% (p = 0.007), whereas maximal handgrip strength showed no significant changes. The SJFT index decreased by 5.0% (p < 0.001), reflecting enhanced intermittent effort efficiency and fatigue tolerance. Large effect sizes were identified for upper-limb reaction speed (d = 1.42), explosive endurance (d = 1.46), and reactive agility (d = 0.96). Conclusions: Over the 15-week study period, participation in a CrossFit-based functional training program integrated into regular Sambo practice was associated with improvements in several biomechanical and neuromuscular performance outcomes, including reaction performance, explosive power, agility, muscular endurance, and sport-specific work capacity. However, because the study did not include a control group, these changes cannot be attributed exclusively to the CrossFit-based intervention. Controlled studies are required to distinguish intervention-specific effects from seasonal training adaptations, continued sport-specific practice, and test familiarization.

Background: Sustainable gymnastics training requires a balance between performance development, injury prevention, workload management, athlete health, psychological well-being, and long-term participation. This focused narrative review aimed to synthesize selected evidence on training optimization, technological applications, athlete health and injury prevention in gymnastics. Methods: A structured narrative review was conducted using the Web of Science Core Collection. The literature search covered publications issued between 1 January 2005 and 30 September 2025, with the final search performed on 30 September 2025. English-language publications retrieved through three predefined Topic searches in the Web of Science Core Collection were considered. The searches covered the period from 1 January 2005 to 30 September 2025 and were restricted to the Sport Sciences category. No additional publications were identified through reference-list screening. Three complementary thematic searches addressing gymnastics training models, technological applications, and injury prevention identified 485 records. After applying the eligibility criteria, removing duplicates, assessing full texts, and excluding ineligible or retracted publications, 140 publications were included in the narrative synthesis. No formal risk-of-bias assessment was performed. Results: The reviewed evidence emphasized progressive and individualized training, workload monitoring, recovery, physical preparation, age-appropriate development, and early identification of pain, fatigue, and other health-related concerns. Injury occurrence was associated with biomechanical loading, rapid growth, training exposure, previous injuries, insufficient recovery, menstrual dysfunction, psychological factors, and discipline-specific technical demands. Wearable sensors, video analysis, biomechanical modelling, artificial intelligence, virtual reality, and digital learning platforms supported movement assessment, technical feedback, training monitoring, and education. Evidence for several emerging technological applications, particularly artificial intelligence and automated assessment, remains preliminary and requires further validation in gymnastics-specific and real-world settings. However, substantial differences in study designs, populations, technologies, outcome measures, and methodological characteristics limited direct comparison across studies. Coaching communication, athlete motivation, psychological well-being, and access to validated technologies also influenced the sustainability of gymnastics training. Conclusions: Sustainable gymnastics training may benefit from an interdisciplinary and athlete-centered approach integrating individualized load management, injury prevention, health monitoring, recovery, educational coaching practices, and appropriately validated technologies. The evidence identified in this review highlights converging themes suggesting the potential value of combining these components to support safe performance development and long-term participation. However, more longitudinal, discipline-specific, and methodologically consistent research is needed.
