- Prescription and Effects of Cardiorespiratory Training in Individuals with Intellectual Disability: a Systematic ReviewPublication . Jacinto, Miguel; Oliveira, Rafael; Martins, Alexandre D.; Brito, João; Matos, Rui; Ferreira, José PedroThis study aims to systematize effects of cardiorespiratory training (CT) programs in individuals with intellectual disability (ID) and identifying the fundamental and structuring aspects for the prescription of CT. This systematic review was carried out through four databases (Pubmed, Web of Science, Scopus, and SPORTDiscus), considering data from the period between 2013 and 2022. From 257 studies, 12 studies were included in this systematic review. Three studies used interval CT, while seven used continuous CT. Seven were carried out in the population with Down syndrome, while only three were carried out with participants with ID. The CT programs had the following characteristics: duration of 8 to 12 weeks, weekly frequency of three sessions, for 20 to 60 min, the intensity of 50% to 80% of maximal heart rate or 70% to 80% of peak oxygen consumption, using an ergometer cycle or an outdoor walking. The studies reported improvements in cardiorespiratory function, lipid, hemodynamic and metabolic profile, body composition, and neuromuscular and cognitive capacity. This review presents characteristics and recommendations that technicians can follow when structuring, prescribing, and implementing CT programs to individuals with ID.
- The relationship between ambient temperature and match running performance of elite soccer playersPublication . Morgans, Ryland; Bezuglov, Eduard; Rhodes, Dave; Teixeira, Jose; Modric, Toni; Versic, Sime; Di Michele, Rocco; Oliveira, RafaelThe influence of environmental factors on key physical parameters of soccer players during competitive match-play have been widely investigated in the literature, although little is known on the effects of sub-zero ambient temperatures on the performance of adult elite soccer players during competitive matches. The aim of this study was to assess how the teams’ match running performance indicators are related to low ambient temperature during competitive matches in the Russian Premier League. A total of 1142 matches played during the 2016/2017 to 2020/2021 seasons were examined. Linear mixed models were used to assess the relationships between changes in ambient temperature at the start of the match and changes in selected team physical performance variables, including total, running (4.0 to 5.5 m/s), high-speed running (5.5 to 7.0 m/s) and sprint (> 7.0 m/s) distances covered. The total, running and high-speed running distances showed no significant differences across temperatures up to 10˚C, while these showed small to large decreases at 11 to 20˚C and especially in the >20˚C ranges. On the contrary, sprint distance was significantly lower at temperature of -5˚C or less compared to higher temperature ranges. At sub-zero temper atures, every 1˚C lower reduced team sprint distance by 19.2 m (about 1.6%). The present findings show that a low ambient temperature is negatively related to physical match perfor mance behavior of elite soccer players, notably associated with a reduced total sprint distance.
- The relationship between wellness and training and match load in professional male soccer playersPublication . Oliveira, Rafael Franco Soares; Canário-Lemos, Rui; Peixoto, Rafael; Vilaça-Alves, José; Morgans, Ryland; Brito, JoãoThe aims of this study were to: (i) analyse the within-microcycle variations in professional soccer players; (ii) analyse the relationships between wellness and training and match load demands; (iii) analyse the relationships between match-day (MD) demands and wellness during the following day (MD+1); and (iv) analyse the relationships between MD and wellness during the day before match-play (MD-1). Thirteen professional soccer players (age: 24.85±3.13 years) were monitored daily over 16-weeks for wellness and training and match-play intensity. The daily wellness measures included fatigue, quality of sleep, muscle soreness, mood and stress using a 1–5 scale. Internal intensity was subjectively measured daily using the rating of perceived exertion (RPE) and the multiplication of RPE by session duration (s-RPE). While external intensity was quantified utilising high-speed running, sprinting, and acceleration and deceleration metrics. Data was analysed from each training session before (i.e., MD-5) or after the match (i.e., MD+1). Repeated measures ANOVA or Friedman ANOVA was used to analyse the aims (i) where Spearman correlation was applied to analyse the relationships between the aims (ii) and (iii) between sleep quality and training intensity. The main results for aim (i) showed that MD+1 presented the lowest values for wellness variables (p < 0.05). While MD-1 presented the lowest internal and external load values (for all variables), with MD presenting the highest values (p < 0.05). Regarding aim (ii), the main result showed significant large negative correlations between fatigue and s-RPE (r = -0.593; p = 0.033). Considering aim (iii), significant small to very large negative correlations were found for sleep quality, fatigue and muscle soreness with all internal and external variables (p < 0.05). Lastly, the main results for aim (iv) showed large negative correlations for fatigue and session duration; fatigue and s-RPE; muscle soreness and session duration; muscle soreness and s-RPE; and muscle soreness and decelerations (p < 0.05, for all). The main conclusions were that MD had an influence on wellness and internal and external training intensity, notably MD-1 and MD+1 were most affected. In this regard, a tendency of higher internal and external intensity on MD was associated with lower wellness measures of sleep quality, muscle soreness and fatigue on MD+1.
- Effects of insect consumption on human health: a systematic review of human studiesPublication . Cunha, Nair; Andrade, Vanda; Ruivo, Paula; Pinto, PaulaInsects have been consumed as food in diverse cultures worldwide, gaining recognition as a sustainable and nutritious food source. This systematic review aims to update information on the impact of insect consumption on human health based on human randomized controlled trials (RCTs) and allergenicity assessment studies. Following PRISMA guidelines, studies published in the last 10 years were analyzed. From one-thousand and sixty-three retrieved references, nine RCTs and five allergenicity studies were analyzed. Post-prandial amino acid levels increased after insect protein consumption. In comparison with other protein sources, insect protein showed no significant differences in the area under the curve (AUC) values for essential amino acids but tended to have lower peaks and peak later. In terms of muscle protein synthesis, there were no significant differences between insect protein and other protein sources. Glucose levels did not differ; however, insulin levels were lower after the consumption of insect-based products. The effects on inflammatory markers and microbiota composition were inconclusive and the studies did not show significant effects on appetite regulation. Allergenicity assessments revealed a sensitisation and cross-reactivity between insect allergens and known allergens. A partial reduction of cross-allergenicity was observed via thermal processing. Insect protein is an adequate protein source with promising health benefits; however, further research is needed to fully understand its potential and optimise its inclusion into the human diet.

- Sustainability Education in the School of Education of Polytechnic Institute of SantarémPublication . Cavadas, Bento; Branco, Neusa; Colaço, Susana; Linhares, ElisabeteThe School of Education of Polytechnic Institute of Santarém (PISantarém) is a teacher education institution with more than 40 years of experience, dedicated to the training of kindergarten educators (0 to 5 years old children) and elementary school teachers (6 to 12 years old students). Sustainability Education (SE) and Sustainability are strongly embedded in the programs and activities of the institution. In fact, we recognize that our goal is to achieve the development of our students’ sustainability competences trough SE, following the goals of this educational process as presented by Bianchi et al. (2022): “provide learners with sustainability competences in order to reflect and embrace sustainability in their daily lives as students, consumers, producers, professionals, activists, policymakers, neighbours, employees, teachers and trainers, organisations, communities, and society at large.” (p. 13). Some examples of how the institution carries out sustainability education are presented in this poster.
- Avaliação do processo de gestão de altas uma contribuição para a melhoria contínua nos Serviços Médicos do Centro Hospitalar do OestePublication . Rosinha, Ana Catarina Marques dos Santos Conceição; Oliveira, SandraCom a crescente necessidade de gerir de forma sustentável os recursos, torna-se imperioso delinear processos de gestão de alta eficazes, padronizados, que sejam capazes de mitigar os fatores que interferem no planeamento de alta, como a comunicação ineficaz, a colaboração ineficiente e a indefinição de papéis. Este trabalho tem como objetivo avaliar e compreender os processos de gestão de altas que ocorrem nos Serviços Médicos do Centro Hospitalar do Oeste e efetuar uma proposta de modelo de planeamento de alta. Para tal, desenhou-se e implementou-se um estudo de natureza qualitativa e quantitativa, descritivo, exploratório e transversal, que levou à aplicação de um questionário aos utentes e cuidadores, assim como aos profissionais de saúde e a realização de focus group envolvendo três grupos distintos de profissionais. Do ponto de vista do cuidador, a escassez de informação e a sua diminuta intervenção no planeamento de alta são as suas principais preocupações. Relativamente aos profissionais, a escassez de tempo para a realização de ensinos, a comunicação deficitária, a insuficiência do trabalho em equipa e a indefinição dos papéis são os principais fatores de insucesso do planeamento de alta. No final foi elaborado um modelo de planeamento de alta, ajustado às características do Centro Hospitalar do Oeste, que resulta da pesquisa bibliográfica e da análise aos resultados obtidos. O modelo proposto prevê uma definição clara de papéis, assente numa comunicação e colaboração multidisciplinar efetiva, tendo em vista uma transição segura de cuidados para a evitar readmissões futuras.
- Assessing the agreement between a global navigation satellite system and an optical-tracking system for measuring total, high-speed running, and sprint distances in official soccer matchesPublication . Makar, Piotr; Silva, Ana Filipa; Oliveira, Rafael; Janusiak, Marcin; Parus, Przemysław; Smoter, Małgorzata; Clemente, Filipe ManuelThis study aimed to compare the agreement of total distance (TD), high-speed running (HSR) distance, and sprint distance during 16 official soccer matches between a global navigation satellite system (GNSS) and an optical-tracking system. A total of 24 male soccer players, who are actively participating in the Polish Ekstraklasa professional league, were included in the analysis conducted during official competitions. The players were systematically monitored using Catapult GNSS (10-Hz, S7) and Tracab optical-tracking system (25-Hz, ChyronHego). TD, HSR distance, sprint distance, HSR count (HSRC), and sprint count (SC) were collected. The data were extracted in 5-min epochs. A statistical approach was employed to visually examine the relationship between the systems based on the same measure. Additionally, R2 was utilized as a metric to quantify the proportion of variance accounted for by a variable. To assess agreement, Bland–Altman plots were visually inspected. The data from both systems were compared using the estimates derived from the intraclass correlation (ICC) test and Pearson product–moment correlation. Finally, a paired t-test was employed to compare the measurements obtained from both systems. The interaction between Catapult and Tracab systems revealed an R2 of 0.717 for TD, 0.512 for HSR distance, 0.647 for sprint distance, 0.349 for HSRC, and 0.261 for SC. The ICC values for absolute agreement between the systems were excellent for TD (ICC = 0.974) and good for HSR distance (ICC = 0.766), sprint distance (ICC = 0.822). The ICC values were not good for HSRCs (ICC = 0.659) and SCs (ICC = 0.640). t-test revealed significant differences between Catapult and Tracab for TD (p < 0.001; d = −0.084), HSR distance (p < 0.001; d = −0.481), sprint distance (p < 0.001; d = −0.513), HSRC (p < 0.001; d = −0.558), and SC (p < 0.001; d = −0.334). Although both systems present acceptable agreement in TD, they may not be perfectly interchangeable, which sports scientists and coaches must consider when using them.
- Phase angle as a key marker of muscular and bone quality in community-dwelling independent older adults: A cross-sectional exploratory pilot studyPublication . Martins, Alexandre; Brito, João; Batalha, Nuno; Oliveira, Rafael; Parraca, Jose A.; Fernandes, OrlandoThe aim of the present cross-sectional exploratory pilot study was to analyze the ability of the Phase Angle (PhA) to predict physical function, muscle strength and bone indicators, upon adjusting for potential confounders [age, sex, lean mass, and body mass index (BMI)]. This study included 56 physically independent older adults (age, 68.29 ± 3.01 years; BMI, 28.09 ± 4.37 kg/ m2 ). A multi-frequency segmental bioelectrical impedance analysis was used to measure PhA at 50 KHz. Additionally, physical function was assessed through four functional capacity tests [30- sec chair-stand; seated medicine ball throw (SMBT); timed up & go; and 6-min walking test (6 MWT)], muscle strength through the handgrip test (dominant side) and maximal isokinetic strength of the dominant knee flexor and extensor. Moreover, bone indicators and body composition were assessed through the dual energy X-ray absorptiometry. PhA was significantly associated with SMBT (r = 0.375, effect size (ES) = moderate); 6 MWT (r = 0.396, ES = moderate); 30-sec chair-stand (rho = 0.314, ES = moderate); knee extension (rho = 0.566, ES = large) and flexion (r = 0.459, ES = moderate); handgrip (rho = 0.432, ES = moderate); whole-body bone mineral content (BMC) (r = 0.316, ES = moderate); femoral neck BMC (r = 0.469, ES = moderate); and femoral neck bone mineral density (BMD) (rho = 0.433, ES = moderate). Additionally, the results of multiple regression analysis demonstrated that PhA is significantly associated with SMBT (p < 0.001; R2 = 0.629), 6 MWT (p = 0.004; R2 = 0.214), knee extension (p < 0.001; R2 = 0.697), knee flexion (p < 0.001; R2 = 0.355), handgrip test (p < 0.001; R2 = 0.774), whole-body BMC (p < 0.001; R2 = 0.524), femoral neck BMC (p = 0.001; R2 = 0.249), and femoral neck BMD (p = 0.020; R2 = 0.153). The results of the preliminary analysis suggested that PhA is linked to muscle strength and some factors related to physical function and bone quality in community-dwelling older adults.
- A influência da diversidade de género na política de distribuição de dividendos:evidência do mercado ibéricoPublication . Moreira, Crisolita Alice Monteiro Furtado; Teodósio, JoãoEsta dissertação analisa o impacto da diversidade de género nos Conselhos de Administração nas políticas de distribuição de dividendos de empresas não financeiras, que integram os principais índices bolsistas de Portugal e Espanha, PSI20 e IBEX 35, respetivamente. A amostra integra 44 empresas, no período compreendido entre 2011 e 2020, com um total de 440 observações. Os resultados desta investigação indicam que o efeito das diretoras mulheres na distribuição de dividendos varia em função da amostra em estudo. Considerando como amostra global o mercado ibérico, a diversidade de género nos Conselhos de Administração não tem efeitos significativos no montante e na percentagem de distribuição de dividendos, embora exista uma tendência para uma associação negativa.
