Training above 1800 m causes increases in hemoglobin, erythropoietin and VO2max values in the bodies of athletes. The purpose of this study is to prove that living at an altitude of 1850 m and training at 2200 m (LHTH+) is more effective than living and training at 2000 m (LHTH). Ten endurance athletes (age 21.2 ± 1.5 years, body mass 55.8 ± 4.3 kg, height 169 ± 6 cm, performance 3000 m 8:35 ± 0:30 min) performed three training sessions of 30 days, in three different situations: [1] living and training at 2000 m altitude (LHTH), [2] living at 1850 m and training at 2200 m (LHTH+), and [3] living and training at 300 m (LLTL). The differences in erythropoietin (EPO), hemoglobin (Hb) concentration, and VO2max values were compared before and at the end of each training session. Data analysis indicated that LHTH training caused an increase in EPO values (by 1.0 ± 0.8 mU/mL, p = 0.002 < 0.05.); Hb (by 1.1 ± 0.3 g/dL, p < 0.001); VO2max (by 0.9 ± 0.23 mL/kg/min, p < 0.001). LHTH+ training caused an increase in EPO values (by 1.9 ± 0.5 mU/ML, p < 0.001); Hb (by 1.4 ± 0.5 g/dL, p < 0.001); VO2max (by 1.7 ± 0.3 mL/kg/min, p < 0.001). At the LLTL training, EPO values do not have a significant increase (p = 0.678 > 0.050; 1 ± 0.1 mU/mL, 0.1 ± 0.9%.), Hb (0.1 ± 0.0 g/dL, 0.3 ± 0.3%), VO2max (0.1 ± 0.1, 0.2 ± 0.2%, p = 0.013 < 0.05). Living and training at altitudes of 2000 m (LHTH) and living at 1850 m training at 2200 m (LHTH+) resulted in significant improvements in EPO, Hb, and VO2max that exceeded the changes in these parameters, following traditional training at 300 m (LLTL). LHTH+ training has significantly greater changes than LHTH training, favorable to increasing sports performance. The results of this study can serve as guidelines for athletic trainers in their future work, in the complete structure of multi-year planning and programming, and thus improve the process of development and performance training.

When assessing the quality and maintainability of large C++ code bases, tools are needed for extracting several facts from the source code, such as: architecture, structure, code smells, and quality metrics. Moreover, these facts should be presented in such ways so that one can correlate them and find outliers and anomalies. We present SolidFX, an integrated reverse-engineering environment (IRE) for C and C++. SolidFX was specifically designed to support code parsing, fact extraction, metric computation, and interactive visual analysis of the results in much the same way IDEs and design tools offer for the forward engineering pipeline. In the design of SolidFX, we adapted and extended several existing code analysis and data visualization techniques to render them scalable for handling code bases of millions of lines. In this paper, we detail several design decisions taken to construct SolidFX. We also illustrate the application of our tool and our lessons learnt in using it in several types of analyses of real-world industrial code bases, including maintainability and modularity assessments, detection of coding patterns, and complexity analyses.

The purpose of this study is to elaborate and validate a scale for the evaluation of the teachers’ attitude towards quality management, by integrating elements of online education. Nine hundred and forty-two teachers from Romania have participated in the study. The exploratory factor analysis has led to the identification of three main dimensions of the scale: (1) communication and alignment; (2) needs and opportunities; and (3) training and support. Teachers participating in managing positions or in quality assurance boards indicated a more positive attitude towards the three components. Furthermore, teachers of a higher teaching experience reported higher values in the needs and opportunities component. The results are useful to educational institutions, program designers and policy makers to evaluate the teachers’ attitude towards quality management.

Background/Objectives: Exercise-induced fatigue is a fundamental component of running performance and training, yet it is also implicated in altered movement mechanics and increased injury risk. While numerous studies have examined fatigue-related biomechanical changes during running, findings remain fragmented across biomechanical domains and fatigue modalities. The purpose of this systematic review was to synthesize contemporary evidence on the effects of fatigue on lower-limb biomechanics during running and to interpret the potential injury relevance of these adaptations. Methods: A systematic literature search was conducted in PubMed, Scopus, and Web of Science for original empirical studies published between January 2010 and December 2025. Eligible studies involved human participants performing running or running-related tasks, applied an explicit fatigue protocol, and reported quantitative lower-limb biomechanical outcomes. Study selection followed PRISMA 2020 guidelines. Data extraction included participant characteristics, fatigue protocols, biomechanical measures, instrumentation, and key findings. Methodological quality was assessed using the Cochrane Risk of Bias 2 (RoB-2) tool. Due to substantial methodological heterogeneity, findings were synthesized narratively. Results: Twenty-four studies met the inclusion criteria. Across studies, fatigue consistently altered spatiotemporal parameters, joint kinematic and kinetic variables, spring-mass behavior, impact loading, coordination variability, neuromuscular output, and inter-limb symmetry. Common adaptations included increased ground contact time, reduced ankle joint power and stiffness, increased joint range of motion, elevated impact loading, and greater movement variability. These changes reflected reduced mechanical efficiency and a redistribution of mechanical load from distal to proximal joints, particularly toward the knee and hip. Similar fatigue-related biomechanical patterns were observed in both laboratory-based and real-world endurance running conditions. Conclusions: Exercise-induced fatigue produces systematic and injury-relevant alterations in lower-limb biomechanics during running. These adaptations may preserve short-term performance but create mechanical conditions associated with increased susceptibility to overuse and non-contact injuries. Integrating fatigue-aware biomechanical assessment, neuromuscular conditioning, and individualized load management strategies may help mitigate adverse fatigue-related adaptations.

(1) Background: This study aimed to examine whether an experimental acrobatics curriculum, conducted three times a week, could lead to greater improvements in specific components of motor fitness—coordination, balance, agility, and speed—compared to the standard physical education program; (2) Methods: The research was conducted over a 16-week period and included 50 seventh-grade students, divided into an experimental group (EG, n = 25) and a control group (CG, n = 25). The experimental group participated in a program of acrobatics and skipping twice a week, while the control group followed the standard physical education curriculum. Motor skills tests were administered before and after the intervention using standardized methods; (3) Results: Results from the ANCOVA analysis showed significant improvements in flexibility, coordination, balance, and agility in the experimental group, with large effect sizes, confirming the effectiveness of the acrobatics and skipping program. However, the impact on speed was variable, indicating the need for specific exercises to improve this ability; (4) Conclusions: The findings are consistent with previous research, highlighting the superiority of specialized acrobatic exercises in enhancing overall motor performance in adolescents. Further research is needed to optimize acrobatics and skipping programs for maximum benefits in the development of motor skills and physical education.

Background: It is well established that healthy lifestyle behaviors have significant effects not only on physical health but also on psychological well-being; however, the underlying mechanisms of these effects have yet to be fully elucidated. In this context, the aim of this study is to examine the relationships between a sustainable healthy lifestyle and levels of depression, stress, and anxiety, and to test the mediating role of physical literacy in these associations. Methods: This cross-sectional study was conducted among university students in Malatya, Türkiye, and a total of 652 voluntary participants were included. In the theoretical model of the study, a sustainable healthy lifestyle was positioned as the independent variable, depression, stress, and anxiety as dependent variables, and physical literacy as the mediating variable. Data were analyzed using structural equation modeling with bootstrapping to assess mediation effects. Results: Results obtained from the structural equation modeling indicate that a sustainable healthy lifestyle has significant and protective relationships with psychological well-being. Negative and significant relationships were identified between a sustainable healthy lifestyle and levels of depression, stress, and anxiety. Furthermore, higher levels of physical literacy were associated with lower levels of these psychological symptoms, with physical literacy playing a strong mediating role in these relationships. The model results revealed that lifestyle components such as regular physical activity, balanced nutrition, and sufficient sleep enhance individuals’ physical competence and awareness. Physical literacy was also found to have a significant negative relationship with depression, stress, and anxiety. Conclusions: These results indicate that physical literacy is a key variable not only for physical functioning but also for psychological resilience and well-being. Moreover, the impact of a sustainable healthy lifestyle on psychological symptoms appears to be largely mediated through physical literacy.
