La investigación en medicina tiene por objetivo generar nuevos conocimientos que ayuden al diagnóstico, el tratamiento y la prevención de enfermedades. Pero la medicina no es una ciencia exacta, sino una actividad humana heterogénea que se basa solo parcialmente en la ciencia, con varios factores no científicos que influyen en la forma de desarrollar esta actividad. El dolor, como síntoma o como enfermedad, es probablemente el trastorno que más afecta y preocupa a las personas y el que con mayor frecuencia (...) motiva una consulta médica. A pesar de la magnitud del problema, y del interés médico y social por el dolor, la atención y el tratamiento de las personas con dolor crónico es un tema infravalorado o tratado inadecuadamente. Con base en múltiples preguntas que se plantean a lo largo del desarrollo del presente documento, nuestro objetivo es, por un lado, el de señalar que los cambios que se han producido en el manejo del dolor crónico hacen de los llamados protocolos de consenso un ejercicio obsoleto en la medicina del siglo XXI. Por otro lado, en términos de bioética, responder a la pregunta ¿se ajustan los protocolos de consenso al principio de beneficencia del paciente individual? (shrink)

Fernando González Ochoa es un referente de la filosofía colombiana y latinoamericana y como tal ha sido tomado en cuenta seriamente por grandes escritores y pensadores a nivel mundial. Entre ellos se encuentra el filósofo francés Jean-Paul Sartre, considerado como uno de los grandes precursores del existencialismo y que presuntamente elogió abiertamente el pensamiento de González. Ante ello, en este artículo se indagará sobre algunas consideraciones que configurarían la construcción de un sujeto existencial en ambos pensadores, colocando entre otras temáticas (...) la mala fe, la remembranza del tiempo y la construcción de una reflexión basada en la existencia que tiene como punto central la aceptación, convicción y certeza de la realidad humana.

El ensimismamiento como categoría antropológica depura la opinión y establece la diferencia entre el hombre y los demás animales. A partir de la obra Ensimismamiento y alteración de Ortega y Gasset, este artículo centra la atención en el ensimismamiento como camino que conduce al sí mismo, a habitar la propia intimidad, a descifrar la auténtica vocación, crear, intervenir y curar las circunstancias, dotándolas de sentido y de significado.

The Gamer's Dilemma challenges us to find a distinction between virtual murder and virtual pedophilia. Without such a distinction, we are forced to conclude that either both are morally acceptable or that both should be morally illicit. This paper argues that the best way to solve the dilemma is, in one sense, to dissolve it. The Gamer's Dilemma rests on a misunderstanding in the sense that it does not distinguish between the form of a simulation and its surface content. A (...) greater appreciation of the way structural features of a simulation affect subject experience will help us see why only simulations of murder and pedophilia generating virtually real experiences are likely to be seen as wrong. I argue that a simulation’s structural elements powerfully affect how subjects experience simulated content and hence is an important, and previously neglected, variable necessary to dissolve the Gamer's Dilemma. Properly understood, virtually real simulations of murder and pedophilia are both likely to be treated by players as morally wrong. Similarly, virtually unreal murder and pedophilia will be less likely to be judged as wrong. Subject judgments are thus consistent once a simulation’s structural variables are accounted for. The Gamer's Dilemma dissolves as a dilemma once we acknowledge these structural features of simulations and how they affect experience and moral judgment. (shrink)

Throughout humanities’ history, telling the truth has always been seen or for that matter understood, as a challenge, as a defiance of the status quo or what is established or known, and could very easily be torn down by an announced truth at any given moment. That is the main reason a speaker, in most cases, will avoid expressing their interpretation of what is real and true, and will prefer to intentionally alter it with convenient and accommodating lies that will (...) not result in any type of discomfort for the people around them. This text presents a general overview of three very important and crucial moments in history, in which daring to tell the truth came to be the very philosophical foundation and gave some specific characters in history the importance and relevance they have been given today. First, it covers a brief review of the ancient Greek term Parrhesia, its relation to other relevant philosophical terms and its importance within the different philosophy schools of the era. Later, the process of how truth is started to be manipulated from a Christian stance and later the proposal of relativity from Friedrich Nietzsche. Finally, there will be a reflection about Michael Foucault’s proposal that relates parrhesia to the care of the self. As a conclusion, an open discussion focusing on the recent post-truth issues illustrating the mechanics involved since ancient times in regard to telling the truth. (shrink)

The reductionist/anti-reductionist debate about testimonial justification (and knowledge) can be taken to collapse into a controversy about two kinds of underlying monitoring mechanism. The nature and structure of this mechanism remains an enigma in the debate. We suggest that the underlying monitoring mechanism amounts to emotion-based stereotyping. Our main argument in favor of the stereotype hypothesis about testimonial monitoring is that the underlying psychological mechanism responsible for testimonial monitoring has several conditions to satisfy. Each of these conditions is satisfied by (...) our “hot” stereotypical capacities. Intergroup emotions play a key role here. Intergroup emotions inform the agent about which candidate stereotype is better suited to the current situation. Emotions serve as evidence that makes a certain stereotype and its particular profile of features more or less expected. (shrink)

In this article, we apply the literature on the ethics of choice-architecture (nudges) to the realm of virtual reality (VR) to point out ethical problems with using VR for empathy-based nudging. Specifically, we argue that VR simulations aiming to enhance empathic understanding of others via perspective-taking will almost always be unethical to develop or deploy. We argue that VR-based empathy enhancement not only faces traditional ethical concerns about nudge (autonomy, welfare, transparency), but also a variant of the semantic variance problem (...) that arises for intersectional perspective-taking. VR empathy simulations deceive and manipulate their users about their experiences. Despite their often laudable goals, such simulations confront significant ethical challenges. In light of these goals and challenges, we conclude by proposing that VR designers shift from designing simulations aimed at producing empathic perspective-taking to designing simulations aimed at generating sympathy. These simulations, we claim, can avoid the most serious ethical issues associated with VR nudges, semantic variance, and intersectionality. (shrink)

Background:The first wave of the COVID-19 pandemic caused a shortage of qualified nurses in Spain. As a result, the government authorized the hiring of senior students.Objectives:To explore the ethical dilemmas and ethical conflicts experienced by final-year nursing students who worked during the first outbreak of the COVID-19 pandemic in Spain.Research design:A qualitative exploratory study was conducted using purposive sampling. Semi-structured interviews were carried out using a question guide. Interviews took place via a private video chat room platform. A thematic, inductive (...) analysis was performed of the information gathered.Participants and research context:Eighteen nursing students were recruited from two universities of Madrid, aged between 18 and 65 years old, enrolled in the fourth year of nursing studies and who were hired under a relief contract for health professionals during the pandemic.Ethical considerations:The present study was carried out in accordance with the Declaration of Helsinki, and the study was approved by the Local Ethics Committee of Universidad Rey Juan Carlos.Results:Three specific themes emerged: (a) coping with patient triage, (b) difficulties in providing end-of-life care, and (c) coping with patient death. Nursing students participated in the process of patient selection for resource allocation and ICU bed occupancy. They were shown how to care for patients who were not admitted to the ICU, in their last moments and were faced with the difficulties of applying end-of-life care. Finally, the nursing students were confronted with the death of their patients, in overwhelming numbers and under adverse conditions.Conclusions:These findings can help shed light on the ethical dilemmas and ethical conflicts faced by novice nursing students, incorporated into the workforce during the COVID-19 pandemic. Moreover, it was described that students may normalize the death due to the exhaustion and overwhelmed routine. (shrink)

Cet article revient sur la couverture médiatique espagnole de l'attentat survenu à la gare d'Atocha à Madrid en mars 2004. L'étude repose sur trois quotidiens madrilènes et un quotidien basque. Il analyse les orientations du discours développé par cette presse dans les jours qui ont suivi cet événement. Il montre qu'intervenant dans un contexte pré-électoral, les différents supports ont, après un moment d'incertitude quant à l'identité des terroristes, orienté essentiellement leurs discours en fonction de leurs orientations idéologiques et de leurs (...) positions à l'égard du gouvernement. Il souligne les convergences observables entre les supports espagnols qui épousent tout en l'accentuant l'émotion ressentie par le lectorat. Il atteste cependant que c'est l'enjeu interne des élections qui a sous-tendu en permanence le traitement de cet événement.This article looks at the media coverage of the Spanish attack in Atocha train station in Madrid in March 2004.

La obra al-D_aji-ra al-saniyya fi- ta�ri-j aldawla al-mari-niyya, que aborda la historia de los Banu- Mari-n, incluye una serie de noticias referentes a otras tierras de la Da-r al-Islam, como Egipto, Siria o al-Andalus. La autoría de la misma no ha sido determinada, por lo que señalaremos las noticias más destacadas sobre este asunto. De la información que ofrece esta obra acerca de al-Andalus, este artículo se centra en el análisis de los fragmentos relativos a los territorios conquistados por Castilla (...) durante el s. XIII, que no había sido aprovechada hasta el momento, y que contribuye a ampliar nuestro conocimiento acerca de este período histórico, muy especialmente por lo que respecta a la suerte que corrieron las poblaciones musulmanas y a la cronología de la conquista. Abordamos las actitudes adoptadas por los dirigentes políticos de al-Andalus y el Magreb, ante el avance de los cristianos, desde la resistencia hasta la conversión, y la importancia que este grupo concedió a las luchas contra los cristianos, que fueron un elemento de legitimación del poder político de los Banu- Mari-n, objetivo destacado del autor de la obra.

Los avances científico-tecnológicos han abierto una brecha en cuanto a los tratamientos médicos y los valores morales que deben sustentar la atención de salud. El profesional de enfermería no está exento de estos peligros, por lo que se ha generado un nuevo modelo ético que se integre al proceso de atención de enfermería. Con el objetivo de determinar los conocimientos y opiniones de estos profesionales, del área de cirugía de mínimo acceso, acerca de la aplicación del modelo en el contexto (...) de estos servicios, se diseñó una investigación de tipo observacional descriptiva con empleo de metodología cualitativa. Como técnica de exploración se usó la entrevista en profundidad, así como un panel de expertos para la construcción de la guía de entrevista. Se entrevistó a 34 enfermeras que laboraban en el Centro Nacional de Cirugía de Mínimo Acceso durante el período del estudio. Se concluye que la práctica de la cirugía de mínimo acceso es propicia para que médicos y enfermeras hagan una mayor observancia del derecho de autonomía de los pacientes. Se reconoce la capacidad de este personal para tomar decisiones independientes de los médicos en cuanto a las acciones de cuidado, lo que implica una mayor responsabilidad. Scientific and technological advances have opened a gap between medical treatments and the moral values that should support health care. The nurse is not exempt from these dangers. As such, a new ethical model that integrates to the process of nursing care has emerged. In order to determine the knowledge and opinions of the professionals who work in minimal access surgery services on the implementation of this model, a descriptive, observational study was designed utilizing qualitative methodology. In-depth interviewing was used as the primary testing technique. A panel of experts from the National Center of Minimal Access Surgery was consulted to develop the interview guide. Thirty-four nurses from the National Center for Minimal Access Surgery were interviewed over the course of the study period. Results suggest that the setting of minimal access surgery is conducive to medical professionals making greater observance of the right to patient autonomy. The ability of this staff to make independent decisions regarding medical care action is recognized, which implies greater responsibility. (shrink)

The objective was to analyze the influence of the social context on bullying. A mixed investigation was proposed: the social context was analyzed, were applied questionnaires and interviews; were analyzed descriptively, normality tests and non-parametric tests; different manifestations of bullying are presented; their frequency varies between both high schools.

In this paper, we argue that, under a specific set of circumstances, designing and employing certain kinds of virtual reality (VR) experiences can be unethical. After a general discussion of simulations and their ethical context, we begin our argu-ment by distinguishing between the experiences generated by different media (text, film, computer game simulation, and VR simulation), and argue that VR experiences offer an unprecedented degree of what we call “perspectival fidelity” that prior modes of simulation lack. Additionally, we argue that (...) when VR experiences couple this perspectival fidelity with what we call “context realism,” VR experiences have the ability to produce “virtually real experiences.” We claim that virtually real experiences generate ethical issues for VR technologies that are unique to the medium. Because subjects of these experiences treat them as if they were real, a higher degree of ethical scrutiny should be applied to any VR scenario with the potential to generate virtually real experiences. To mitigate this unique moral hazard, we propose and defend what we call “The Equivalence Principle.” This principle states that “if it would be wrong to allow subjects to have a certain experience in reality, then it would be wrong to allow subjects to have that experience in a virtually real setting.” We argue that such a principle, although limited in scope, should be part of the risk analysis conducted by any Institutional Review Boards, psychologists, empirically oriented philosophers, or game designers who are using VR technology in their work.

This paper makes two essential claims about the nature of shame and shame punishment. I argue that, if we properly understand the nature of shame, that it is sometimes justifiable to shame others in the context of a pluralistic multicultural society. I begin by assessing the accounts of shame provided by Cheshire Calhoun (2004) and Julien Deonna, Raffaele Rodogno, & Fabrice Teroni (2012). I argue that both views have problems. I defend a theory of shame and embarrassment that connects both (...) emotions to “whole-self” properties. Shame and embarrassment, I claim, are products of the same underlying emotion. I distinguish between moralized and nonmoralized shame in order to show when, and how, moral and non-moral shame may be justly deployed. Shame is appropriate, I argue, if and only if it targets malleable moral or non-moral normative imperfections of a person’s ‘whole-self.’ Shame is unjustifiable when it targets durable aspects of a person’s “whole-self.” I conclude by distinguishing shame punishments from guilt punishments and show that my account can explain why it is wrong to shame individuals on account of their race, sex, gender, or body while permitting us to sometimes levy shame and shame punishment against others, even those otherwise immune to moral reasons.

This volume highlights interdisciplinary research on the ethical, metaphysical, and experimental dimensions of extended reality technologies, including virtual and augmented realities. It explores themes connected to the nature of virtual objects, the value of virtual experiences and relationships, experimental ethics, moral psychology in the metaverse, and game/simulation design. -/- Extended reality (XR) refers to a family of technologies aiming to augment (AR) or virtually replace (VR) human experience. The chapters in this volume represent cutting-edge research on XR experiences from a (...) wide range of approaches including philosophy, psychology, Africana studies, and cognitive sciences. They are organized around three guiding questions. Part 1, “What is Extended Reality?”, contains a series of chapters examining metaphysical questions about virtual objects, actions, and worlds. Part 2, “Is There an Ethics for Extended Realities?”, includes chapters that address ethical questions that arise within XR experiences. Finally, Part 3, “What Can We Do with Extended Realities?”, features chapters from a diverse group of social scientists on the potential uses of XR as an investigative and educational tool, including its strengths and pitfalls.

BackgroundThe use of dedicated training programs for improving decision-making (DM) in team sports players has grown in the last several years. Approaches such as imagery training, video-based training, or game-based drills are some of the interventions used in youth players in order to improve DM. However, no systematic reviews or meta-analyses have been conducted to summarize the main evidence regarding the effects of these programs on the players and identify the magnitude of the effects compared to control groups.ObjectiveThis systematic review (...) (with meta-analysis) was conducted to assess the effects of training programs on the DM of youth team sports players.Data SourcesThe data sources utilized were PubMed, PsycINFO, Scopus, SPORTDiscus, and Web of Science.Study eligibility criteriaThe criteria included the following: (i) youth (≤ 18 years old) team sports players with no restriction on sex or competitive level; (ii) players subjected to training programs to develop DM; (iii) control groups; (iv) pre–post outcomes related to tactical behavior, technical execution, reaction, and decision time; and (v) controlled trials.ResultsThe database search initially identified 2497 titles. From these, six articles were eligible for the systematic review and meta-analysis. The results showed a significant beneficial effect of DM interventions on tactical behavior (ES = 1.12;p= 0.035;I2= 80.0%; Egger’s testp= 0.066), whereas no significant effect of DM interventions on technical execution was found (ES = 0.74;p= 0.180;I2= 69.1%; Egger’s testp= 0.873).ConclusionThe DM interventions were significantly effective in improving tactical behavior in youth team sports players independently from the number of sessions to which players were exposed. In addition, DM interventions were significantly effective in improving technical execution. However, the results should be carefully interpreted due to the heterogeneity of the articles’ overall methodological quality. Future DM interventions should consider using combined approaches that allow players to develop both tactical behavior and technical execution. (shrink)

Podemos sugerir sin temor a equivocarnos que After Virtue significó un antes y un después para la investigación filosófica acerca de la moral y generó un renacido interés por la ética clásica, especialmente de las virtudes. Pero lejos de haber quedado en el pasado After Virtue es hoy bibliografía obligatoria para quien quiera comprender la ética contemporánea y sus estructuras sociales del orden moral. Es inviable estudiar las características de la ética actual sin un desarrollo histórico de sus raíces filosóficas: (...) que abarca a enemigos de la razón como Hume y Calvino, es continuada por los fundadores de la ilustración y que termina con la crítica letal de Nietzsche a todos los intentos modernos de enmascarar la voluntad de poder bajo formas contractuales o racionalistas de la moral. Además, para todo aquel que camina tras el pensamiento del filósofo Alasdair MacIntyre, esta obra contiene un esbozo y diseño intelectual de lo que serán sus obras posteriores. Por eso, a 40 años de su publicación decidimos evocar sus principales aportes, que mantienen solidez y vigencia a pesar de los años. (shrink)

Nuestro objetivo examinar las razones por las que se dice que la modernidad ha entrado en crisis y por qué sus avances, tan glorificados en la Ilustración, representan más bien un retroceso. En este sentido, se abordará en un primer momento la crítica realizada por un pensador que, aún inserto en esta época, vislumbra los elementos que han constituido el fracaso de algunos proyectos occidentales. Tal es el caso de Nietzsche, quien fue uno de los primeros que criticaron a la (...) razón y a la noción de verdad; a la primera en tanto facultad sobrevalorada e irracional, y a la segunda como una ficción, creada por el ser humano en tanto útil para sus empresas prácticas. Asimismo, se menciona de forma breve a Max Weber y su concepto de Jaula de Hierro en cuanto fue una de las primeras reflexiones sobre la modernidad entendida como periodo de debilitamiento de las ideas absolutas sobre el mundo. En segundo lugar, se abordará la teoría crítica de la Escuela de Frankfurt, concentrándose en la caracterización que hacen de la razón como razón instrumental. La crítica que realizan estos teóricos se centra en los supuestos que han coronado a la razón y al conocimiento científico como el centro y la jerarquía más alta de todo saber. Una vez hecho esto, se abordará la crítica más reciente a la modernidad dentro de la tradición occidental, conocida bajo el nombre de Posmodernidad.La última parte del escrito busca determinar qué es aquello que se conoce bajo el nombre de Posmodernidad. Para esto, se establecerán cuáles son los problemas relativos a su definición, se analizarán algunos de los elementos del contexto histórico que influyeron en su surgimiento y, por último, se hablará acerca de su alcance teórico. A pesar de ser un concepto problemático, y no tener un núcleo teórico concreto, este concepto se ha usado para definir la aparente crisis de valores generada a partir de la Segunda Guerra Mundial y la expansión del capitalismo en su forma globalizada. Más aún, la tendencia mayoritaria de la Posmodernidad es rechazar, en su totalidad, los valores desarrollados y defendidos en la modernidad. (shrink)

We aim to generate a dilemma for virtual reality-based research that we motivate through an extended case study of Judith Thomson’s (1985) Bridge variant of the trolley problem. Though the problem we generate applies more broadly than the Bridge problem, we believe it makes a good exemplar of the kind of case we believe is problematic. First, we argue that simulations of these thought experiments run into a practicality horn that makes it practically impossible to produce them. These problems revolve (...) around concepts that we call “perspectival fidelity”and “context realism.” Moral dilemmas that include features present in the Bridge variant will, as a result, be practically impossible to simulate. We also argue that, should we be wrong about the practical impossibility of creating a VR simulation of Bridge, such a simulation must face an ethical horn which renders these simulations ethically impermissible to develop or use. For these reasons, we argue that it is virtually impossible to simulate the bridge problem (and other thought experiments with similar features) both practically and ethically in VR. (shrink)

In this paper, we assess the impact of extended reality technologies as they relate to sexual forms of harassment. We begin with a brief history of the nature of sexual harassment itself. We then offer an account of extended reality technologies focusing specifically on psychological and hardware elements most likely to comprise what has been referred to as “the metaverse”. Although different forms of virtual spaces exist (i.e., private, semi-private, and public), we focus on public social metaverse spaces. We do (...) this to better explain how the concept of sexual harassment must be adjusted to such spaces and how approaches aimed at mitigating harassment must be sensitive to the type of metaverse spaces users utilize. We then offer a typology of sexual harassment for the metaverse focusing on three distinct forms of sexual harassment: (1) invariant (2) mixed variance or modified and (3) unique or metaverse specific. Although existing normative and legal frameworks may function well with respect to the first and, possibly, second forms of harassment, we argue such frameworks will not helpfully address metaverse-specific harassment. Ultimately, the changing nature of privately owned public spaces (POPS) which metaverses are likely to represent pose distinct ethical and regulatory challenges. (shrink)

BackgroundFor a long time, in sports, researchers have tried to understand an expert by comparing them with novices, raising the doubts if the visual search characteristics distinguish experts from novices. Therefore, the aim of the present study was to review and conduct a meta-analysis to evaluate the differences in visual search behavior between experts and novices in team sports athletes.MethodsThis systematic review with meta-analysis followed the PRISMA 2020 and Cochrane's guidelines. Healthy team athletes were included, which engaged in regular practice, (...) from any sex or competitive level, specifically classified a priori as expert or novice in the original research. We considered only research published in peer-reviewed journals, with no limitations regarding date or language. It was considered healthy team sport athletes engaged in regular practice. The scenarios could be in situ or film-based. The databases of EBSCO, PubMed, Scopus, SPORTDiscus, and Web of Science were used to perform the searches. The risk of bias was calculated through the RoBANS tool.ResultsFrom a total of 6,257 records, of which 985 were duplicates, titles and abstracts of 5,272 were screened, and 45 required full-text analysis. Of those, 23 were excluded due to not fulfilling the eligibility criteria regarding participants. In the end, 22 studies were selected, however, as two studies were part of the same trial and were analyzed conjointly.DiscussionExperts showed to be older and with more years of practice. The ability to distinguish experts from novices was not so clear regarding the variables analyzed. This could be due to the strategies chosen in each study, which were specific to each scenario, and when grouping all together, it was lost information within non-representative averages. The distinction between experts and novices was not clear, showing a lot of heterogeneity in the included studies. The expert classification itself may have been the conditioning aspect for these results, retaining the doubt and the need for more studies in the field.Systematic review registrationThe protocol was pre-registered in OSF.

This paper addresses a variant of the job shop scheduling problem with total tardiness minimization where task durations and due dates are uncertain. This uncertainty is modelled with intervals. Different ranking methods for intervals are considered and embedded into a genetic algorithm. A new robustness measure is proposed to compare the different ranking methods and assess their capacity to predict ‘expected delays’ of jobs. Experimental results show that dealing with uncertainty during the optimization process yields more robust solutions. A sensitivity (...) analysis also shows that the robustness of the solutions given by the solving method increases when the uncertainty grows. (shrink)

The authors of Beziau and Franceschetto work with logics that have the property of not satisfying any of the formulations of the principle of non contradiction, Béziau and Franceschetto also analyze, among the three-valued logics, which of these logics satisfy this property.

However, the enrichment of a language with an (...) implication connective leads us to more interesting systems, therefore we look for one implication for these logics and we study further properties that the logics obtain when this connective is added to these systems.

O artigo discute passagens importantes da obra de Santo Agostinho e argumenta que muitas são as antecipações de teses comumente atribuídas a Descartes. Entre elas, uma clara antecipação à célebre fórmula “penso, logo existo” na obra do Bispo de Hipona, assim como de outras teses importantes distribuídas ao longo de sua obra. Na segunda parte, culmina o texto com outro dado praticamente desconhecido: o fato de que o estilo meditativo empregado por Descartes também já fora antecipado por uma autora cuja (...) obra era amplamente conhecida na Europa da metade do século XVI e do século XVII. Trata-se da freira Teresa D’Ávila que fora canonizada quando o jovem Descartes estudava com os jesuítas em La Flèche.

Background: Mental fatigue can impact physical demands and tactical behavior in sport-related contexts. Small-sided games are often used to develop a specific sport-related context. However, the effects of mental fatigue on physical demands and tactical behaviors during soccer SSGs have not been aggregated for systematical assessment.Objective: This systematic review was conducted to compare the effects of mental fatigue vs. control conditions in terms of the total running distance and tactical behavior of soccer players during SSGs.Methods: The data sources utilized were (...) PubMed, PsycINFO, Scielo, Scopus, SPORTDiscus, and Web of Science. The study eligibility criteria were established based on PICOS: Population: healthy youth and young adult men soccer players with regular training practice and belonging to teams with regular competitions; Intervention: exposed to mental fatigue-induced protocols only before SSGs; Comparator: control conditions before SSGs; Outcomes: physical demands and tactical behavior ; Study design: counterbalanced cross-over design; and only full-text and original articles written in English.Results: The database search initially identified 111 titles. From those, six articles were eligible for the systematic review and meta-analysis. Results showed no significant effect of fatigue on total running distance and tactical behavior.Conclusions: A non-significant effect of mental fatigue on total running distance and tactical behaviors performed by soccer players during SSGs was found in this systematic review.
