- Blueberry Extract and Resistance Training Prevent Left Ventricular Redox Dysregulation and Pathological Remodeling in Experimental Severe Pulmonary Arterial HypertensionPublication . Leite, Luciano Bernardes; Soares, Leôncio Lopes; Guimarães-Ervilha, Luiz Otávio; Costa, Sebastião Felipe Ferreira; Generoso, Sara Caco dos Lúcio; Xavier, Mirielly Alexia Miranda; Iasbik-Lima, Thainá; Oliveira, Leandro Licursi; Lucia, Ceres Mattos Della; Bianchi, Sara Elis; Bassani, Valquíria Linck; Herter, Flavio Gilberto; Turck, Patrick; Araujo, Alex Sander da Rosa; Forte, Pedro; Reis, Emily Correna Carlo; Machado-Neves, Mariana; Natali, Antônio JoséTo investigate whether the regular administration of blueberry extract and low-intensity resistance exercise training (RT), either alone or in combination, during the development of monocrotaline (MCT)-induced severe pulmonary arterial hypertension (PAH) in rats protect the left ventricle (LV) from redox dysregulation and pathological remodeling. Groups of seven male Wistar rats were formed for the experiment: sedentary control; sedentary hypertensive; sedentary hypertensive blueberry; exercise hypertensive; and exercise hypertensive blueberry. PAH was experimentally induced through a single intraperitoneal administration of MCT at a dose of 60 mg/kg. One day after injection, the blueberry groups started receiving a daily dose of blueberry extract (100 mg/kg) by gavage, while the exercise groups initiated a three-week program of RT (ladder climbing; 15 climbs carrying 60% of maximum load; one session/day; 5 times/week). Echocardiographic evaluations were conducted 23 days after injection, and the rats were euthanized the next day to harvest LV tissue. Separately, blueberry extract and RT mitigated augments in pulmonary artery resistance, LV tissue redox dysregulation (i.e., increased PC levels) and detrimental remodeling (i.e., reduced inflammation), and reductions in ejection fraction (EF) and fractional shortening (FS) caused by PAH. The combination of treatments prevented reductions in EF and FS, along with the development of a D-shaped LV. blueberry extract and moderate-intensity resistance training administered during the development of MCT-induced severe PAH in rats prevented LV redox dysregulation and pathological remodeling, thereby preserving its function.
- Characterization of physical performance and change of direction deficit across age groups in young female volleyball playersPublication . Oliveira, João P.; Marinho, D.A.; Jacinto, Pedro; Sampaio, Tatiana; Morais, J. E.Background Volleyball performance relies heavily on agility, strength, and the ability to change direction, yet there is limited research investigating these physical attributes across different age groups in youth volleyball players. The change of direction (COD) deficit—a metric that isolates directional efficiency by comparing agility to linear speed— may provide a more nuanced understanding of an athlete’s movement capabilities. The aim of this study was to investigate: (i) the differences in anthropometrics, lower limb strength/power, dynamic balance, linear sprint speed, and change of direction (COD) ability between young volleyball age groups; (ii) the effect of age on COD deficit in young volleyball players, and; (iii) the COD deficit predictors. Methods A cross-sectional analysis of young volleyball athletes was conducted. Seventy-seven female volleyball players from three age groups (U13:12.43 ± 0.89; U16:14.38 ± 0.52; U18:16.78 ± 0.93) participated in standardized tests measuring their physical qualities. Results The older age groups (U18) were significantly taller, heavier, and faster in linear sprints than their younger counterparts. No significant differences between groups were observed in lower limb strength and power or dynamic balance. The U16 group demonstrated the lowest COD deficit. The regression analysis identified drop jump height (DJ) as the sole significant predictor of COD deficit, explaining 6.9% of the variance (R2 = 0.069, p = 0.033), highlighting its relevance as an indicator of reactive strength. Conclusions These findings suggest that while anthropometric features have increased and sprint performance improved with age, there is no corresponding improvement in lower limb strength, power, or dynamic balance. Drop jump height was the sole predictor of COD deficit, emphasizing the importance of reactive strength in determining agility. Coaches should focus on enhancing lower limb strength and reactive power to optimize COD performance and prevent performance stagnation (training plateaus), particularly in older athletes
- Comparative Effects of Resistance Training Modalities on Mental Health and Quality of Life in Individuals with Spinal Cord InjuryPublication . Santos, Lucas Vieira; Freitas, Karla Raphaela da Silva Ramos; Pereira, Eveline Torres; Leite, Luciano Bernardes; Forte, Pedro; Oliveira, Claudia Eliza Patrocínio de; Moreira, Osvaldo CostaBackground: Anxiety and depression are prevalent after spinal cord injury, impairing social participation and quality of life. Objective: This study aimed to investigate the effects of traditional resistance training (TRT), flywheel resistance training (FWRT), and high-velocity resistance training (HVRT) on the mental health and quality of life in individuals with spinal cord injury. Methods: Thirty-two participants were divided into TRT (n = 12), FWRT (n = 8), and HVRT (n = 12) groups, undergoing 8 weeks of upper-limb training twice weekly under super-vision. Training intensity and volume were progressively increased. The Hospital Anxiety and Depression Scale and SF-36 Questionnaire were used to assess outcomes. Results: Both the TRT and FWRT groups showed a reduction in HADS-D scores post-intervention (p < 0.001). The TRT group also presented a significant reduction in HADS-A scores post-intervention (p = 0.003). Concerning quality of life, after training, TRT showed improvements in social functioning (p = 0.013), FWRT improved scores in physical functioning (p = 0.002), bodily pain (p = 0.002), vitality (p = 0.046), and role emotional (p < 0.001), while HVRT enhanced role physical (p < 0.001), social functioning (p = 0.013), and role emotional (p < 0.001). Conclusion: Overall, TRT was the most effective in reducing anxiety and depression and enhancing quality of life, while FWRT showed notable gains in physical and functional capacity. HVRT demonstrated improvements primarily in role physical but was less effective in other domains.
- Comparison of the Active Drag and Passive Drag Coefficients at the same Swimming Speed Through Experimental MethodsPublication . Lopes, Tiago J.; Pinto, Mafalda P.; Oliveira, João P.; Marinho, Daniel A.; Morais, J. E.; Sampaio, TatianaStudies about drag in swimming usually report or put the focus on its absolute value. However, it is being claimed that the drag coefficient better represents the hydrodynamic profile of a swimmer. Drag is strongly dependent on speed. Thus, increases in speed will lead to increases in drag. This could lead to misleading interpretations since drag is the water resistance that makes the swimmers’ displacement difficult. Conversely, the drag coefficient is less dependent on speed, which can be seen as a more appropriate measure of the swimmers’ hydrodynamic profile. This study used a complete experimental methodology (experimental and cross-sectional study) to determine the resistive forces in crawl swimming at the same speed (i.e., 1.00, 1.05, 1.10 m/s, etc.). In 10 proficient non-competitive adult swimmers (seven men and three women), the drag coefficient (CD ) was compared and the difference between using the technical drag index (TDI) with drag (D, passive or active) or with its respective CD 's. Measurements of active drag (DA ), passive drag (DP ) and CD (CDA and CDP ) were carried out. The TDI was calculated as a measure of swimming efficiency and the frontal surface area (FSA) obtained in active conditions. The active FSA was 20.73 ± 5.56% greater than the passive FSA (large effect size), the propulsion was 58.29 ± 69.61% greater than drag and CDA was 24.60 ± 46.55% greater than CDP (moderate effect size). TDI was significantly lower, but with a small effect size when measured with CD values compared to drag. TDID vs TDICD revealed strong agreement (> 80% of plots were within IC95). This study concludes that proficient swimmers presented a CDA greater than the CDP, but with strong agreement between them, probably due to FSA during active conditions. CD data appears to be a more absolute indicator of drag than TDI.
- Diálogo entre culturas: a Cultura Indígena como resposta à dominação cultural na interlocução entre Enrique Dussel e Paulo FreirePublication . Alves, Deisiane; Cancian, Queli; Mesquita, ElzaNeste artigo analisamos o entrelaçamento entre cultura e educação, considerando os aspectos históricos que se relacionam a ambas no contexto brasileiro, desde os processos colonizadores, cujos elementos permearam a formação da identidade nacional. Processos estes que invisibilizaram a Cultura Indígena, seus saberes e tradições, elementos aqui destacados, como forma de contar uma outra história. Para tanto, nos embasamos na revisão bibliográfica, a partir da interlocução entre Enrique Dussel e Paulo Freire, ícones dos estudos pós-coloniais e decoloniais, que enfatizaram ao longo de toda sua trajetória, a dominação cultural exercida pelos processos colonizadores e a necessária identificação e libertação desta.
- Digital Humanities at the Service of Remembrance: The Creation of Digital Archive-based Activities within the Project Remembering the Past, Learning for the FuturePublication . Gombár, Zsófia; Martins, Cláudia F.D.; Ferro, Maria João; Fernandes, Ana Raquel; Szőnyi, Andrea; Xavier, Catarina; Komoly, Gabriella; Mezei, MónikaThis article explores the usage of testimonies in the Visual History Archive of the University of Southern California's Shoah Foundation to create learner-centred activities on the history of the Holocaust targeted at Portuguese students. We describe the project ‘Remembering the Past, Learning for the Future: Research-Based Digital Learning from Testimonies of Survivors and Rescuers of the Holocaust’, housed at the University of Lisbon Centre for English Studies (ULICES). Via the international partnership (USC Shoah Foundation, Zachor Foundation, and the University of Eötvös Loránd), the ULICES team developed materials using testimony from witnesses and survivors of the Holocaust through digital tools with an innovative pedagogical methodology. We introduce the constructivist theory of learning, stressing the powerful impact of survival testimonies on raising student awareness and developing a wide range of skills. We also describe the methodological process that underlay this project, namely the creation of the six learning activities for the IWitness educational platform and the IWalk visits, focusing on the translation tasks of the written materials and the audiovisual translation of the videos. We also report on how students received the activities by retrieving information from teachers’ and students’ reports, and an onsite experience with two groups of students.
- Effects of On-Court Tennis Training Combined with HIIT versus RST on Aerobic Capacity, Speed, Agility, Jumping Ability, and Internal Loads in Young Tennis PlayersPublication . Morais, J. E.; Kilit, Bulent; Arslan, Ersan; Bragada, José A.; Soylu, Yusuf; Marinho, DanielThe purpose of this study was to compare the effects of on-court tennis training (OTT) combined with high-intensity interval training (HIIT) or repeated sprint training (RST) on the physiological, kinematic, kinetic, and perceptual responses of young tennis players. Twenty-four male tennis players (age 13.6 ± 0.3 years) were randomly assigned to either the OTT + HIIT group (n = 12) or the OTT + RST group (n = 12) three times per week for six weeks. Both groups trained for the same total training time with passive rest in each session. A number of physiological, performance and perceptual responses were measured before and after the 6-week training intervention. All variables showed a significant improvement over time, with maximal oxygen uptake showing the greatest improvement (p < 0.001, η2 = 0.97). The 5-m sprint (p = 0.044, η2 = 0.17), repeated sprint ability (p = 0.021, η2 = 0.22), and T-drill agility (p = 0.048, η2 = 0.17) showed a significant group effect. The OTT + RST group had a lower internal training load (better scores), a lower rate of perceived exertion (better scores), and higher scores in the Physical Activity Enjoyment Scale (PACES) at both times compared to the OTT + HITT group. These results demonstrate that OTT + RST appears to be a more effective training approach to improve speed and agility-based performance responses with more enjoyment in young tennis players.
- Hierarchical clustering of the pre-exam anxiety levels in physically inactive and active adolescent students from 56 countries: an observational study using PISA program dataPublication . Encarnação, Samuel; Teixeira, José Eduardo; Forte, Pedro; Leite, Luciano Bernardes; Sortwell, Andrew; Branquinho, Luís; Ferraz, Ricardo; Afonso, Pedro; Vaz, Paula Marisa Fortunato; Monteiro, António M.The relationship between physical activity and anxiety among students has been extensively studied, with research highlighting the protective effects of physical activity on mental well-being. Methods: This article synthesizes existing literature on the topic and presents a novel analysis of pre-exam anxiety rates among physically inactive high school students from 56 countries. Using data from the Programme for International Student Assessment (PISA) 2018, a hierarchical clustering method was applied to identify four clusters based on strati ed country groups by the students pre-exam anxiety levels. Results: The results indicated ve clusters for low physically active students (three with higher anxiety rates and two with lower levels of the condition) and four clusters for the low physically active individuals (two for higher anxiety rates and two for lower levels). Furthermore, the hierarchical model worked with good precision in the clustering task. In conclusion, considering the low physically active students, Brazil (82%) and the Dominican Republic (81%) recorded the highest pre-exam anxiety levels, while the Czech Republic (35%) had the lowest. Among the physically active students, Malaysia (82%), Brazil (81%), and Costa Rica (81%) recorded the highest anxiety levels, whereas again, the Czech Republic (35%) had the lowest. Discussion: These ndings emphasize that although physical activity generally relates to reduced anxiety, this association varies across cultural and educational contexts.

Faustino, Florêncio; Silva, Constantino; Gonçalves, Bruno F.Nos últimos anos, temos assistido a uma revolução tecnológica que está transformando radicalmente a maneira como as pessoas aprendem e os educadores ensinam. Um dos avanços tecnológicos mais promissores nesse campo é a inteligência artificial. Pesquisas nesse campo podem influenciar políticas educacionais, garantindo que as regulamentações estejam alinhadas com as melhores práticas. Este artigo tem como objectivo discutir a integração da inteligência artificial na educação, bem como as suas implicações do uso dessa tecnologia em ambientes educativos. Em termos de metodologia, optou-se pela pesquisa bibliográfica, baseada em consultas de obras científicas. Em termos de conclusões, a partir deste artigo, percebemos que a inteligência artificial tem um potencial de revolucionar a educação e traz benefícios significativos, mas também conduz desafios enormes que exigem muita atenção. Dentre as principais implicações ou riscos da IA na educação destaca-se a dependência excessiva da IA na educação que pode criar uma lacuna digital. Para além desta implicação, sinaliza-se a digitalização de tarefas educacionais por meio da IA que pode levantar preocupações sobre a substituição de professores. Por fim, destaca-se o facto que a IA pode ser usada para criar conteúdo falso, como trabalhos de pesquisa ou respostas a exames, representando um risco a ética e desonestidade académica.
- Machine learning classification of consumption habits of creatine supplements in GYM goersPublication . Magalhães, Patrícia C.; Encarnação, Samuel; Forte, Pedro; de Araújo Teixeria, José Eduardo; Monteiro, António M.; Barbosa, Tiago M.; Pereira, Ana M.; Encarnação, Samuel; Pereira, Ana Maria Geraldes RodriguesThe aim is to identify usage patterns and the main factors that influence creatine supplementation, providing a basis for future educational interventions and recommendations for safe and effective use. The study was applied to gym goers in Bragança, where a QR code for a survey was released. 158 people participated, 65 non-consumers of creatine supplementation (37.34% men; 22.78% women) and 95 consumers (15.19% men; 24.68% women). Five machine learning algorithms were implemented to classify creatine consumption in gym goers: Logistic Regression, Gradient Boosting Classifier, Ada Boost Classifier, Xgboost Classifier. K-folds cross-validation was implemented to validate the machine learning performance. There was an increased proportion of females with considered themselves not sufficiently informed about the creatine effects/side effects (22.2%) in comparison to males (8.47%), p=0.03. The AdaBoost classifier exposed the best overall performance (86%) in classifying overuse of creatine in gym goers based on their Smoke habits (r = 0.33), grams of creatine used per day (r = 0.50) and lack information about the side effects of creatine intake (r = -0.33). The K-folds method validates the results with very good performance (86%). In conclusion, the five machine learning methods employed well characterized the overuse of creatine in gym goers based on smoke habits, grams of creatine per day, and lack information about the side effects of creatine intake.
