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.

Judo is a multifactorial sport where many variables or key performance indicators such as force-velocity profile, bioenergetic capacity, technical and tactical skills, and cognitive and emotional competence play a role and influence the final result. While there have been many academic studies of these variables, usually in isolation, none have examined KPIs holistically or analyzed their impact on strategic performance. The main objective of the present study, therefore, is to apply a novel and easily replicable methodology to identify and prioritize (...) the main KPIs affecting performance in professional judo. Such a methodology was applied to the High-Performance Judo Centre of Valencia, using a multi-criteria decision aid technique: the analytic network process. The ANP is used to identify and quantify cause and effect relationships not only between KPIs but also between KPIs and performance objectives. Further, the ANP offers effective results when there is a lack of historical KPI data, because it is based on experts' opinions and judgments. A judo expert group comprising elite judo coaches and half-lightweight male judokas applied the methodology to discriminate between the characteristics required when aiming to reach high-level strategic objectives. The JEG, which consisted of five elite judokas, national and international champions, and three Olympic coaches—including a former European champion and silver medalist in a world championship—provided high added value to the study. The main findings were that the KPIs that made the most difference were mostly psychological, specifically motivation, stress, and team cohesion. Of these, motivation was by far the most important KPI for success in our case study, so judokas should make sure that they analyze it properly. Motivation is usually intrinsic to the competitor and should be maintained at a high level, not only during tournaments but also during daily training and lifestyle activities. Physical and other specific forms of training, as well as lifestyle KPIs, are very important for the elite competitor but are not sufficient to reach high-level objectives. The most important of these KPIs were Kumi-Kata, dual career, focus and concentration level, scouting, nutrition, and basic technique. Power and strength were the most important physical KPIs. In general, these are essential for meeting strategic objectives, but they do not make the crucial difference. This suggests that professional psychological support should be provided in daily training and that international team composition and internships should be fostered. (shrink)

El presente artículo traza la semblanza intelectual y profesional del religioso José Mª Salvador y Barrera, natural de Marchena, que llegó a ser Rector del Colegio del Sacro Monte de Granada, Obispo de Tarazona, Obispo de Madrid-Alcalá, Arzobispo de Valencia y Senador, y que dedicó todos sus esfuerzos a defender la enseñanza religiosa y la acción social de la Iglesia desde los altos puestos que ocupó. Fue además un excelente orador y persona de gran cultura, siendo reconocida su (...) labor por las Reales Academias de la Historia y de Ciencias Morales y Políticas, que le eligieron como académico de número. El obispo Salvador fue realmente uno de los prelados más competentes y aperturistas de los dos primeros decenios del siglo XX. (shrink)

Today the definition of Spain as a national, historical and sovereign entity is in crisis. This situation has been reached because the Spanish left has assumed as its own many of the ideas about the concept of the Spanish nation of peripheral nationalisms. In this article we try to discover the causes of this identification through the study of the propaganda texts that the opposition to the Franco regime had on the national concept, rescued in the rulings of the Public (...) Order Court. In them we will observe how the opposition to Francoism in the Basque Country, Catalonia, Galicia and the Canary Islands mixed Marxist and nationalist ideologies in their messages, but with great fundamental differences in each of these regions. Furthermore, we certify that the "Burgos Process" was the turning point that cemented the identification of the Spanish left throughout the country with the nationalist movements. (shrink)

This paper explores the similarities between the conceptual structure of quantum theory and relational biology as developed within the Rashevsky-Rosen-Louie school of theoretical biology. With this aim, generalized quantum theory and the abstract formalism of (M,R)-systems are briefly presented. In particular, the notion of organizational invariance and relational identity are formalized mathematically and a particular example is given. Several quantum-like attributes of Rosen’s complex systems such as complementarity and nonseparability are discussed. Taken together, this work emphasizes the possible role of (...) self-referentiality and impredicativity in quantum theory. (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 presente trabajo pretende indagar el problema de la vida intelectual creadora en el ámbito universitario y el impulso de la realización de «lo mejor» con visión, claridad de pensamiento y razón de la vida desde el pensamiento mariano y superar de este modo el peligro de quedarse instalado en el academicismo filosófico, que enfatiza la erudición, la acumulación de información más que el aprendizaje, la relaciones interpersonales, el pensamiento propio u otras maneras de ver la realidad.

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)

El hombre mediocre está integrado por las lecciones sobre psicología del carácter que dio José Ingenieros en la cátedra de la Facultad de Filosofía y Letras de Buenos Aires, durante el año 1910. En ellas se proponía comprender cómo funcionan las sociedades humanas. Para ello establecía y describía tres tipos o caracteres que según él era posible reconocer en cualquier comunidad de seres humanos: el idealista, el hombre mediocre y el inferior. Ingenieros no ocultaba su admiración hacia el primer (...) tipo pero, más allá de los juicios morales. Hizo el esfuerzo de entender en clave psicológica las particularidades de cada tipo y su función específica en nuestras sociedades. Así, dedicaba una parte importante de El hombre mediocre al segundo tipo, porque él constituye el grueso de las sociedades: «¿La continuidad de la vida social sería posible sin esa compacta masa de hombres puramente imitativos, capaces de conservar los hábitos rutinarios que la sociedad les transfunde mediante la educación? El mediocre no inventa nada, no crea, no empuja, no rompe, no engendra; pero, en cambio, custodia celosamente la armazón de automatismos y prejuicios y dogmas acumulados durante siglos, defendiendo ese capital común contra la asechanza de los inadaptables. Su rencor a los creadores compénsase por su resistencia a los destructores.». (shrink)

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.

Este artículo tiene por objeto explicar cuándo en el estado de necesidad la distinción entre un mal mayor o menor responde al universo ético consecuencialista y desde qué consideraciones no lo haría; segundo, explicar por qué es posible desde el principio del doble efecto la ponderación de la vida humana, aceptando la objetivización de sus parámetros según los efectos de una acción. Por ello, a continuación trataremos en la primera sección el concepto de mal en clave consecuencialista y, posteriormente, moral (...) absolutista. Se trata de un análisis sobre la materia que reconoce, en la segunda sección, la importancia de la existencia de estos universos en la ponderación de males. Luego, contrastaremos nuestros razonamientos con las soluciones que, para casos semejantes, se proponen desde el doble efecto para algunas situaciones de estado de necesidad. Finalmente, en la tercera sección, entregaremos los criterios de una política criminal para distinguir y no encubrir exigencias deónticas en el estado de necesidad. (shrink)

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)

El objetivo de este trabajo es mostrar la importancia que tiene recuperar el concepto de «ideología» y con él la labor de crítica ideológica en la teoría del derecho. En las teorías positivistas de Kelsen y Ross era uno de los conceptos centrales, pero cayó paulatinamente en desuso en la segunda mitad del siglo xx, tanto a nivel político como en el campo específico de la teoría jurídica. En este trabajo se examinan algunas de las razones por las que se (...) dejó de utilizar y se propone un concepto de «ideología» capaz de evitar esos cuestionamientos. Por último, se ponen de manifiesto las consecuencias perjudiciales (tanto teóricas como prácticas) que trae aparejado el abandono de la crítica ideológica en la teoría jurídica. Se utiliza como caso de estudio la concepción postpositivista sobre la naturaleza del derecho defendida por Manuel Atienza y algunas de las decisiones argumentativas que el propio Atienza ha adoptado guiado por ella en una polémica sobre el estatus normativo de la gestación por sustitución en la práctica jurídica española.

The rise in Study Abroad participation among college students has increased interest among educationalists wondering about the impact of SA on students, particularly when students return home without evidence of deep engagement and understanding of other cultures and people. The purpose of this case study was to locate one potential source of the meanings ascribed to the SA experience, through analysis of multimodal representations on the institutional website of a popular SA program provider. In this study, Kress’ model of multimodal (...) social semiotic communication was employed in the analysis of the ensemble of modes of communication on the website, and their role in the production and dissemination of discourses of SA. Findings indicate that discourses of tourism prevail over discourses of education, and the representations enacted on the institutional website are mirrored in the discursive practices of students.

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.

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)

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.

In the context of a didactic for learning and updating the texts and classical languages, this work proposes a translation and interpretation of the philosophical and political sense of the fable The Aged Horse of Babrius. The translation follows the Greek version of Crusius and the Gredos edition, while the interpretation is based on the philosophical and political reflections of Cicero and Plutarch in On old Age and Whether an old man should engage in plublic affairs. These reflections can also (...) be seen from a statistical analysis of Long-Lived Men of Lucian of Samosata. Thus, the meaning of the fable says that young statesmen should avoid becoming the next useless politicians or “old horses” of the State. This reflection contributes today to weigh the political participation of young people and updates the civic importance of the elderly in their intervention on public affairs. (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.

There is widespread agreement that an adequate understanding of the nature of science (NOS) is a critical component of scientific literacy and a major goal in science education. However, we still do not know many specific details regarding how students and teachers learn particular aspects of NOS and what are the most important feature traits of instruction. In this context, the main objective of this review is to analyze articles from nine main science education journals that consider the teaching of (...) NOS to K-12 students, pre-service, and in-service science teachers in search of patterns in teaching and learning NOS. After reviewing 52 studies in nine journals that included data regarding participants’ views of NOS before and after an intervention, the main findings were as follows: (1) some aspects of NOS (empirical basis, observation and inference, and creativity) are easier to learn than others (tentativeness, theory and law, and social and cultural embeddedness), and subjective aspects of NOS and “the scientific method” seemed to be difficult for participants to understand; (2) the interventions most frequently lasted 5 to 8 weeks for students, one semester for pre-service teachers, and 1 year for experienced teachers; and (3) most of the interventions incorporated both decontextualized and contextualized activities. Given the substantial diversity in the methods and intervention designs used and the variables studied, it was not possible to infer a pattern of more-effective NOS teaching strategies from the reviewed studies. Future investigation should focus on (a) disentangling whether a difference exists between the easy and difficult aspects of learning NOS and formulating a theoretical explanation for distinguishing the two types of aspects and (b) assessing the effectiveness of different kinds of courses (e.g., history of science, NOS or informal) and strategies (e.g., hands-on vs. drama activities; SSI vs. HOS).

El SARS-CoV-2 más conocido como COVID 19 ha evidenciado de forma radical como el sistema capitalista neoliberal, nos ha llevado a una serie de maquillajes de la realidad que no permitían ver la gravedad de su construcción de inequidad, pero lo que es peor, al convertir en una empresa rentable todo lo que toca, termino por desdibujar la democracia, la justicia, y el estado mismo.

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)

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.

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.

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)

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.

Background: Small-sided games are an adjusted form of official games that are often used in training scenarios to introduce a specific tactical issue to team sports players. Besides the acute effects of SSGs on players' performance, it is expectable that the consistent use of these drill-based games induces adaptations in the technical execution and tactical behaviors of youth team sports players.Objective: This systematic review with meta-analysis was conducted to assess the effects of SSG programs on the technical execution and tactical (...) behaviors of young and youth team sports players.Data Sources: The data sources utilized were PubMed, Scopus, SPORTDiscus, and Web of Science.Study Eligibility Criteria: Young and youth team sports players (i.e., 17 and <17 SSG training sessions, respectively.Conclusions: This systematic review and meta-analysis revealed a significant beneficial effect of using SSG training programs for enhancing technical execution in young and youth players. The benefits were similar despite the various numbers of training sessions applied. Further studies should add tactical behaviors as one of the outcomes for controlling the effects of SSG training programs. (shrink)
