- Analysis of thermal patterns in the knee: comparative study between athletes and sedentary individualsPublication . Araújo, Mirela dos Santos; Bernardes Leite, Luciano; Forte, Pedro; Malheiro, Alexandra; Januário, William Martins; Pussieldi, Guilherme de Azambuja; Coelho, Bruno de Cássio; Barreiros, Marta de Oliveira; Barros Filho, Allan Kardec Duailibe; Assis, Miller Gomes de; Navarro, Antônio Coppi; Rodrigues Junior, Jefferson Fernando Coelho; Oliveira, Mario Norberto Sevilio de; Cabido, Christian Emmanuel Torres; Pimenta, Eduardo Mendonça; Veneroso, Christiano EduardoInfrared thermography is a non-invasive technique that detects skin-emitted radiation, providing insights into body temperature and identifying thermal changes related to inflammatory or degenerative processes. This study aimed to compare knee temperatures between sedentary individuals and athletes and to evaluate differences between the anterior and posterior knee regions. A convenience sample included 32 men, 16 sedentary individuals (1.71 ± 0.05 m; 71.7 ± 11 kg; BMI: 24.5 ± 0.39 kg/m²) and 16 athletes (1.79 ± 0.06 m; 73.29 ± 11 kg; BMI: 22.84 ± 2.52 kg/m²). Temperature assessments were conducted using infrared thermography. The results showed that the posterior knee region consistently exhibited higher temperatures than the anterior region in sedentary individuals (p < .001) and athletes (p < .001). Sedentary individuals had lower knee temperatures compared to athletes, both in the posterior regions (right: p = .0006; left: p = .0035) and anterior (right: p < .0001; left: p = .0009). These findings highlight that physical training influences localised thermal responses, with athletes demonstrating higher average knee temperatures and a consistent temperature gradient between the posterior and anterior regions in both groups.
- Classification of dementia risk in the elderly through gait analysis with machine learning algorithmsPublication . Costa, Raí Braz; Almeida, Samuel Gonçalves; Encarnação, Samuel; Schneider, André; Barbosa, Tiago M.; Teixeira, José Eduardo; Forte, Pedro; Monteiro, António M.The irreversible and progressive decline of physiological functions is known as aging. Among these changes is brain aging, which leads to cognitive decline and the onset of dementia. This directly affects memory, learning, and motor skills, reducing gait efficiency. This study aimed to investigate the feasibility of identifying and classifying the risk of dementia based on the analysis of kinematic variables related to gait in older adults using machine learning algorithms. This cross-sectional observational study examined a sample of 59 individuals aged 60 +/- 8 years, divided into two groups: 26 institutionalized older adults (GI) and 33 non-institutionalized older adults (GNI), all residing in Bragan & ccedil;a, Portugal. Gait data were collected during a 10-m walk, recorded on video, and analyzed using Kinovea software. Cognitive status was assessed using the Mini-Mental State Examination (MMSE). Python (TM) was used for statistical analysis and to develop machine learning models to classify dementia risk based on gait variables. The results showed that the algorithmic models achieved an overall accuracy of 74.6%, with the AdaBoost algorithm performing best at 83.5%. Cross-validation revealed an overall accuracy of 72%, with the Support Vector Machine (SVM) classifier achieving the highest individual performance at 80%, correctly classifying 80% of cases across different data subsets. In conclusion, gait analysis combined with machine learning algorithms demonstrated a strong relationship between gait variables and dementia, proving to be a safe and efficient technique for dementia classification. This approach offers a low-cost and accessible early identification and intervention method, with potential applications in clinical and public health settings.
- Comparative analysis of physical fitness and body composition in first-year bachelor sports sciences students from France and PortugalPublication . Morais, J.E.; Larrière, Onésie; Bragada, José A.; Bartolomeu, Raúl Filipe; Magalhães, Pedro; Schnegg, Antoine; Houndekon, Martial; Garnier, Yoann M.; Mourot, LaurentPhysical fitness and body composition are foundational to the training and academic success of sports sciences students. However, baseline physical profiles may vary across institutions and countries, reflecting differences in cultural, educational, and physical activity environments. This study aimed to compare physical fitness levels and anthropometric characteristics of first-year sports sciences students from three European institutions in France and Portugal. A cross-sectional study was conducted with 172 first-year university students (121 males, 51 females) enrolled in sports sciences programs at one French (UMLP) and two Portuguese institutions (IPB and IPG). Participants completed a standardized physical fitness test battery assessing aerobic capacity (estimated VO(2)max), upper- and lower-body strength (handgrip, isometric mid-thigh pull), explosive power (standing long jump), flexibility (sit-and-reach), and balance (standing stork test). Anthropometric measures included body mass, fat mass, and lean mass. Group and gender differences were analyzed using ANOVA and effect sizes. Students from UMLP displayed significantly higher performance in estimated VO(2)max (IPB vs UMLP d = 1.08; IPG vs UMLP d = 0.81), strength (isometric mid-thigh pull [IPB vs UMLP d = 0.65; IPG vs UMLP d = 0.73]), flexibility (IPB vs UMLP d = 0.61; IPG vs UMLP d = 0.69), balance (IPG vs UMLP d = 0.91), and body composition (higher lean mass [IPB vs UMLP d = 0.19; IPG vs UMLP d = 0.28], lower fat mass [IPB vs UMLP d = 0.22; IPG vs UMLP d = 0.31]) compared to their Portuguese peers. IPG students outperformed the other groups in the standing long jump test (IPB vs IPG d = 0.51; IPG vs UMLP d = 1.38). Males consistently outperformed females across all fitness domains except flexibility. Significant group-by-gender interactions were observed for flexibility and strength measures. This study highlights substantial differences in physical fitness and body composition among first-year sports sciences students across institutions in France and Portugal. These findings underline the importance of assessing students' physical readiness at university entry and suggest that institutional and cultural factors may influence physical health trajectories. Targeted interventions may be warranted to ensure baseline fitness equity and promote academic and athletic success.
- Diálogo entre culturas: a Cultura Indígena como resposta à dominação cultural na interlocução entre Enrique Dussel e Paulo FreirePublication . Alves, Deisiane; Cancian, Queli Ghilardi; 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; 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.
- Écriture de la frontière: Persepolis de Marjane Satrapi entre occidentalisation et identité iraniennePublication . Alves, Ana M.; Outeirinho, Maria de FátimaDans le cadre du questionnement contemporain sur les formes littéraires de pensée de l’Occident, Persepolis de Marjane Satrapi se signale par son inscription dans une double dynamique critique : d’une part, l’écriture autobiographique y interroge les logiques de l’occidentalisation ; d’autre part, le roman graphique propose une mise en récit des tensions entre subjectivités postcoloniales et imaginaires occidentaux dominants. Cette œuvre s’inscrit pleinement dans une démarche de « pe(a)nser l’Occident » à partir du littéraire. Persepolis constitue une écriture de la frontière – géopolitique, culturelle et intime – dans laquelle l’auteure met en scène une identité en transit entre l’Iran postrévolutionnaire et l’Europe contemporaine. L’Occident y apparaît comme un objet à la fois désirable, normatif et problématique. Satrapi déconstruit les discours orientalistes et les mythes de l’Occident libérateur, tout en évitant l’écueil d’un contre-discours simplement inversé. Elle donne ainsi à voir les contradictions internes de l’occidentalisation, vécue dans la chair de l’exil et du retour, et les ambiguïtés d’un « occidentalisme » intériorisé ou projeté. À travers une écriture graphique singulière, Satrapi propose un espace littéraire où se rejouent les rapports entre pouvoir, culture, genre et mémoire. L’écriture devient ici instrument de résistance, d’auto-représentation et de réinvention identitaire. Dans cette perspective, Persepolis s’inscrit dans un horizon post-occidental où la littérature francophone contemporaine devient un lieu stratégique de reconfiguration symbolique face à l’hégémonie des représentations occidentales. Ce travail propose ainsi une lecture de Persepolis comme enquête littéraire sur les formes d’occidentalisation et de décentrement postcolonial, inscrite dans une poétique de la frontière et du déplacement, en dialogue avec les problématiques du post-Occident.
- Effects of High-Intensity Interval Training on Functional Fitness in Older AdultsPublication . Schneider, André; Leite, Luciano Bernardes; Santos, Fernando; Teixeira, José Eduardo; Forte, Pedro; Barbosa, Tiago M.; Monteiro, António M.The global increase in life expectancy has generated growing interest in strategies that support functional independence and quality of life among older adults. Functional fitness—including strength, mobility, flexibility, and aerobic endurance—is essential for preserving autonomy during aging. In this context, physical exercise, particularly High-Intensity Interval Training (HIIT), has gained attention for its time efficiency and physiological benefits. This randomized controlled trial aimed to evaluate the effects of a group-based HIIT program on functional fitness in older adults. Functional outcomes were assessed before, during, and after a 65-week intervention using standardized field tests, including measures of upper and lower body strength, flexibility, aerobic endurance, and agility. This study was prospectively registered at ClinicalTrials.gov (NCT07170579). Significant improvements were observed in the HIIT group across multiple domains of functional fitness compared to the control group, notably in upper body strength, lower limb flexibility, cardiorespiratory endurance, and mobility. These results suggest that HIIT is an effective and adaptable strategy for improving functional fitness in older adults, with the potential to enhance performance in daily activities and support healthy aging in community settings.
- Effects of hydrotherapy on gait control in older adults with neurological conditions: A systematic reviewPublication . Rodrigues, Zélia; Pires, Patrícia; Pires, Sónia; Gonçalves, Sara; Pires, TelmaHydrotherapy appears safe and more effective than conventional physiotherapy for improving gait control, balance, and mobility in older adults with neurological impairments. Its buoyancy and resistance effects facilitate motor re-education and confidence in movement. Integrating aquatic therapy into neurorehabilitation programs may enhance outcomes and quality of life, although long-term follow-up studies are still needed.
- O galego na literatura portuguesa e vice-versa: uma proposta didática inovadora para o estudo da literatura comparada luso-galegaPublication . Dotras Bravo, Alexia; Santos, Filipa Raquel VeledaThe aim of this research is to verify the hypothesis that in the teaching of foreign literature to Portuguese students, they exhibit a predisposition towards negative biases against their own national literature. This phenomenon arises from the mandatory nature of studying Portuguese literature during their academic education, which often leads to its rejection and hinders a deeper understanding of it. Conversely, foreign literature studied at higher education levels frequently sparks genuine interest among students, as they have no prior knowledge of or prejudice against it. The innovative methodology will be developed in the context of Spanish literature at a higher education institution in Portugal. The goal is to expose students to and surprise them with Hispanic culture beyond Castilian. This approach also aims to reconnect Portuguese students with their own literature through Galician, establishing a less conventional connection to Castilian. In this way, an intimate bond is fostered between the three Atlantic languages, using translation as a driving force to generate a sense of discovery. To achieve this, innovative activities will be implemented, including the introduction of texts devoid of context, creating ambiguity regarding their linguistic origin and authenticity
- The Impact of Knee Braces on Plantar Pressure Distribution in Elderly Individuals: Implications for Fall Risk PreventionPublication . Lumini, José; Ribeiro, Andrea; Schneider, André; Monteiro, António M.; Sousa, JoãoFalls are a major public health concern in older adults, largely due to age-related declines in proprioception and postural control. Although knee braces are commonly prescribed to enhance joint stability and sensory feedback, their effects on plantar pressure distribution remain unclear; Thirteen community-dwelling older adults (mean age: 79.6 ± 3.2 years) participated in a repeated-measures study under three conditions: no brace, knee brace A, and knee brace B. Plantar pressure variables were assessed barefoot during quiet standing using a baropodometric platform. Conditions were compared using non-parametric Friedman tests; Significant differences were observed for left foot total surface area (p = 0.041) and left rearfoot surface area (p = 0.020). Compared with no brace, brace A increased plantar contact area, whereas brace B reduced it. No significant differences were found for pressure magnitude, load distribution, or right foot variables; Knee braces induce subtle, brace-specific and lateralized changes in plantar pressure distribution, potentially reflecting altered postural control strategies. Although limited to specific variables, these effects may be clinically relevant for fall risk assessment and individualized knee brace prescription in older adults.
