- Analytical and Ecological Approaches to Aerobic and Anaerobic Conditioning in FootballPublication . Morgans, Ryland; Oliveira, Rafael; Oliveira, Rafael; Silva, Rui; Beato, Marco; Bishop, Chris; Turner, AnthonyResearch in professional football has shown that the physical demands of competitive match-play have substantially increased over the last few decades (Carling et al., 2016) as well as the training demands (Oliveira et al., 2022). As such, the role of support staff has developed to provide theoretical, scientific, and practical support to the manager in a variety of areas. These include performance analysis, strength and conditioning, and the integration of technical and tactical elements. The role of fitness and conditioning staff is to have knowledge of scientific literature and analyze performance data to condition and recover players appropriately to deal with the ever-evolving demands of elite football competition.

- Efectividade dos Cuidados de Enfermagem de Reabilitação no domicilio à pessoa em situação de AVCPublication . Silva, Rui; Lourenço, Jose; Esparteiro, Maria JoãoO presente relatório teve como objectivos, reflectir sobre processo de aquisição de competências do enfermeiro especialista em enfermagem de reabilitação e analisar a efectividade dos cuidados de enfermagem de reabilitação no domicílio á pessoa em situação de AVC, recorrendo ás etapas da prática baseada na evidência e mobilizando a metodologia PI[C]O. A análise dos artigos seleccionados para a revisão sistemática da literatura, evidencia que os cuidados de enfermagem de reabilitação no domicílio promovem ganhos de independência no auto cuidado e nas capacidades da família/cuidador em cuidar, com implicações positivas na recuperação funcional e social da pessoa em situação de AVC. No entanto, não aprofunda alguns aspectos relacionados com a efectividade da reabilitação domiciliária, como sejam, o seu custo-eficácia, satisfação dos clientes /cuidadores, prevenção de complicações/reinternamentos, entre outros, que importa analisar, por forma a constituir a reabilitação no domicílio á pessoa em situação de AVC uma alternativa efectiva ás unidades de reabilitação. ABSTRACT The objective of this report was to reflect on the process of skills acquisition of the specialist nurse in rehabilitation nursing as well analyzing the effectiveness of home rehabilitation nursing care for an individual in a CVA situation, using the evidence-based practice steps and mobilizing the PI[C]O methodology. The analysis of selected articles for the systematic review of literature reveals that home nursing rehabilitation care promote independence gains in self care and in the ability of the family/caregiver to take care with positive implications on the functional and social recovery of the individual in a CVA situation. However, does not develop some aspects related to the effectiveness of home rehabilitation, such as its cost-effectiveness, customer/caregivers satisfaction, prevention of complications/rehospitalizations, among others, which must be analysed, in order to make home rehabilitation to an individual in a CVA situation an effective alternative to institutional rehabilitation units.institucionais.

Clemente, Filipe Manuel; Oliveira, Rafael; Silva, Rui; Akyildiz, Zeki; Halil, Ibrahim Ceylan; González, Javier Raya; Fernández, Francisco Tomás González; Araújo, Rui; Sarmento, Hugo; Lima, Ricardo; Silva, Bruno; Matos, Sérgio; Chen, Yung-Sheng; Afonso, JoséThis book systematically summarizes the accuracy, precision, and repeatability levels of field-based tests applied in soccer. It considers such details as the effectiveness of tests for different age categories and sexes. In this book, the readers will be able to check all the field-based tests conceived for fitness assessment in soccer through a large systematic review made to the literature. In addition a brief characterization of each test and presentation of the concurrent validity and repeatability levels for each test will be provided. Finally, the book contains a general discussion of the implications of the tests for different methodological approaches to training. It will be use to sports scientists and practitioners.
- The influence of playing position on physical, physiological, and tchnical demands in adult male soccer matches: a systematic scoping review with evidence Gap MapPublication . Sarmento, Hugo; Martinho, Diogo V.; Gouveia, Élvio R.; Afonso, José; Chmura, Paweł; Field, Adam; Savedra, Nestor Ordoñez; Oliveira, Rafael; Praça, Gibson; Silva, Rui; Barrera-Díaz, Joel; Clemente, Filipe ManuelBackground There has been an increase in studies examining the demands of soccer relative to each playing position in recent years. Understanding the physical, physiological, and technical demands on soccer players according to their positional role during competitive matches is necessary to understand match requirements and develop position-specifc training practices. Thereby, there is a clear need to synthesize the information on the diferent profles of each playing position. Objective This review aimed to organize the literature investigating physical, physiological, and technical demands accord ing to playing positions and provide a framework to identify gaps and suggestions for future studies. Methods A systematic search was conducted in October 2023 using four electronic databases: Web of Science, SPORT Discus, PubMed and Scopus. The review followed PRISMA 2020 guidelines and the PRISMA-ScR extension for Scoping Reviews. The studies were included if the sample comprised adult male soccer players categorized from Tier 3 to Tier 5 (i.e., highly trained/national level, elite/international level, or world class) and compared the physical, physiological, or technical parameters across playing positions. Results A total of 178 studies met the inclusion criteria and were included in the review. The number of teams, players, and matches analyzed per study varied considerably. Although a range of classifcations were reported across studies, 59% of studies classifed players as central defenders, full-backs, central midfelders, wide midfelders, and forwards. The fnd ings suggests that central and external midfelders, and external defenders cover greater total and high-speed distance than forwards or central defenders. Sprint distance was higher in external midfelders versus all other positions. Defenders and central midfelders perform more passes than external midfelders and forwards. Heart rate was the most commonly reported physiological variable across playing positions. When expressed as a percentage of maximal heart rate, midfelders presented higher mean values than all other playing positions. Conclusion This scoping review demonstrates that there are diferences in the demands on players across playing positions in soccer. Training practices in soccer should be based on the specifc requirements of each positional role to ensure players can fulfll their tactical responsibilities during the game.
- Jogos reduzidos para o treino da aptidão cardiorrespiratóriaPublication . Silva, Rui; Oliveira, Rafael; Clemente, Filipe Manuel"Jogos reduzidos também conhecidos como jogos condicionados consistem em tarefas que modificam a estrutura dinâmica de um jogo normal por constringir algum tipo de tarefa no mesmo (1,2). Este tipo de jogos tem vindo a aumentar a sua popularidade e utilização no futebol porque permitem treinar e aumentar a perceção dos jogadores de algumas questões técnico-táticas e ao mesmo tempo permitem a variação de estímulos fisiológicos (3,4). De igual modo produzem uma eficácia semelhante aos métodos tradicionais de treino cardiorrespiratório (de corrida) sem o uso de bola para desenvolver aptidão física dos jogadores (3). "
- A systematic review of the criterion validity and reliability of technical and tactical field-based tests in soccerPublication . Clemente, Filipe Manuel; Praça, Gibson; Oliveira, Rafael; Aquino, Rodrigo; Araújo, Rui; Silva, Rui; Sarmento, Hugo; Afonso, JoséBackground: Field-based tests are important since they can guarantee ecological validity. Although most such tests are designed to assess physical fitness, tactical and technical dimensions are also determinants in a full battery of tests. Objectives: This systematic review aimed to (a) summarize the criterion validity and reliability of technical and tactical field-based tests applied in soccer and (b) list valid and reliable technical and tactical field-based tests. Methods: A systematic review of EBSCO, PubMed, Scielo, SPORTDiscus, and Web of Science databases was performed according to PRISMA guidelines. The eligibility criteria included (i) population (soccer players from any age group, com petitive level, or sex); (ii) exposure (exposure to technical and/or tactical field-based tests covering individual technical skills, tactical behaviours, tactical knowledge, and decision-making in the field); (iii) comparator (a laboratory test and/ or a criterion field-based test); (iv) outcome (measures of reliability); and (v) no restrictions concerning study design. The synthesis of results focused on the outcomes considered in the eligibility criteria. Results: A total of 5008 titles were identified, of which 21 met the eligibility criteria. Eight studies’ analyses centred on tactical tests. Of those, six studies tested the same instrument (FUT-SAT), one study examined divergent thought, and one study used a soccer-specific skills test Among the 10 included studies involving technical tests, only two repeated the same test (the Loughborough Soccer Passing Test). Three studies included tests concurring with physical ones. According to the main findings, the eight studies that used tactical tests revealed that the outcomes obtained from the tests and observers were reliable. The 10 studies that used technical tests, as well as the three concurrent studies, revealed similarly high reliability. Of the eight studies that used tactical tests, seven involved youth participants. Furthermore, three of the 10 studies that conducted technical tests were done on adults. Of the concurrent tests, three involved youth athletes. Only one study including a tactical analysis presented values for validity, while three others provided information about validity. The four studies provided information about test validity. Conclusions: Overall, the selected technical and tactical tests, most of which were carried out on youth players, revealed their validity and reliability. Although most studies focused on reliability (which was confirmed regardless of the test included), criterion validity was also observed in the few studies that analysed such factors. Thus, the tests cur rently proposed for assessing technical and tactical behaviours possess acceptable criterion validity and reliability.

- Variations of external workload across a soccer season for starters and non-startersPublication . Nobari, Hadi; Silva, Rui; Manuel Clemente, Filipe; Oliveira, Rafael; Carlos-Vivas, Jorge; Pérez-Gómez, JorgeThe aims of this study were to (i) analyze within-group (starters and non-starters) for the weekly acute (wAW), chronic (wCW), and acute:chronic workload ratio (wACWR) throughout the pre-, early-, mid-, and end-season periods, and (ii) analyze the within-group differences for the weekly total distance (wTD), sprint total distance (wSTD), high-speed running distance (wHSRd), and repeated sprint (wRS) throughout the soccer season. The study included a professional soccer team that participated in the highest level of the Iranian Persian Gulf Pro League during a full season. A Global Positioning System was used for data collection during the study. Results revealed significant differences between season periods for wAW and wACWR for both starters (wAW: p = 0.003, ηP2 = 0.541; wACWR: p < 0.001, ηP2 = 0.964) and non-starters (wAW: p < 0.001, ηP2 = 0.696; wACWR: p < 0.001, ηP2 = 0.943). Only non-starters had meaningful differences for wCW (p = 0.009, ηP2 = 0.408). There were significant differences in wTD and wSTD for both starters (wTD: p < 0.001, ηP2 = 0.810; wSTD: p = 0.014, ηP2 = 0.457) and non-starters (wTD: p < 0.001, ηP2 = 0.895; wSTD: p < 0.001, ηP2 = 0.781). Only non-starters showed significant differences (p < 0.001, ηP2 = 0.722) for wRS, while both groups showed no significant differences for wHSRd. In conclusion, these results revealed that both groups experienced significant differences in wAW, wACWR, wTD, and wSTD, while non-starters presented significant differences in wCW and wRS. Coaches should consider these group differences when planning training sessions. Exposure to wSTD and wRS should be addressed for non-starters, as well as fatigue monitoring for starters, especially for players with full match participation.
