This article examines an area that has received surprisingly little attention within the sociology of sport literature: the role of human movement and the ways in which it can be understood and valued. Drawing on the work of Pierre Bourdieu and Judith Butler, in this article, the authors have raised the possibility of sporting “movement capital.” The authors argued that rules and regulations produce and legitimize particular types of movements, which are then reinforced through institutionalized athlete development practices and able to be converted to symbolic capital. However, movements might also be valued as demonstrating particular traits and/or invoking emotional reactions, and be recognized as familiar. The authors concluded that, through identifying the connections between Bourdieu’s habitus and Butler’s performativity, they can understand how the value of movement is constantly in-flux, constantly regenerating as athletes imperfectly produce and reproduce recognizable movements as part of their sporting habitus.

According to Lorentz transformations, for a stationary observer, time in a moving inertial reference frame slows down, while the linear dimensions are reduced. While the first effect was observed more than 80 years ago, the second one has not been directly observed so far. The modified Duguay method is proposed in this paper for measuring the Lorentz contraction of a moving body length using the propagation of light pulses in an optical liquid medium. Three variants of the measurement scheme are considered: with a 'light square' in an optical medium, with a 'light ruler' in two optical media with different refractive indices, and with two relativistic electron bunches in a vacuum. It is shown that the classical effect of compression of spatial intervals between light pulses in an optical medium, which was not considered earlier, considerably reduces the measurement accuracy. It is also shown that the distortion of the sides of a light square oriented orthogonal to the movement direction caused by the different delays of light from different parts of a moving body also reduces the measurement accuracy of the light square method.

In the heterogeneous corpus of works published by sons of Argentinean desaparecidos one of the most interesting and original contribution are the texts written by Félix Bruzzone. The aim of this article is to outline the main characteristics of the author’s style and then to analyse his last novel Campo de Mayo (2019). The novel actually originates as another type of text, a performance, so first of all, the peculiarities of this textuality will be identified, in order to reflect on the mechanisms that intervene when a performance is transposed into a novel. It will be demonstrated that the novel keeps many elements of the performance, all linked to the theme of the search for disappeared parents, that ensure that the dynamic corporeal characteristic of the hipotext is kept in its novelisation, in order to create a discourse that through the body of the protagonist displays all the contradictions and paradoxes that this impossible search implies, using de textual image of the moving body to give an account of the complex dynamics of identity definition concerning sons of desaparecidos.

Purpose The purpose of this study is to perform computational analysis on the steady flow and heat transfer due to a slot nanojet impingement onto a heated moving body. The object is moving at constant speed and nanoparticle is included in the heat transfer fluid. The unsteady flow effects and interactions of multiple impinging jets are also considered. Design/methodology/approach The finite volume method was used as the solver in the numerical simulation. The movement of the hot body in the channel is also considered. Influence of various pertinent parameters such as Reynolds number, jet to target surface spacing and solid nanoparticle volume fraction on the convective heat transfer characteristics are numerically studied in the transient regime. Findings It is found that the flow field and heat transfer becomes very complicated due to the interaction of multiple impinging jets with the movement of the hot body in the channel. Higher heat transfer rates are achieved with higher values of Reynolds number while the inclusion of nanoparticles resulted in a small impact on flow friction. The middle jet was found to play an important role in the heat transfer behavior while jet and moving body temperatures become equal after t = 80. Originality/value Even though some studies exist for the application of jet impingement heat transfer for a moving plate, the configuration with a solid moving hot body on a moving belt under the impacts of unsteady flow effects and interactions of multiple impinging jets have never been considered. The results of the present study will be helpful in the design and optimization of various systems related to convective drying of products, metal processing industry, thermal management in electronic cooling and many other systems.

This paper aims to contribute to the theoretical discussion and empirical application of phenomenology in the sociology of sport by drawing on Maxine Sheets-Johnstone’s theories. I propose that Sheets-Johnstone’s movement-focused phenomenology can be complementary to Merleau-Ponty’s phenomenology of the body in the analyses of sporting moves and the learning of new moves. I mainly applied two concepts from Sheets-Johnstone, tactile-kinesthetic/kinetic dynamics and emotion-motion dynamics, to explore the moving body in waka ama (outrigger canoe) paddling, based on my beginner’s and other competent paddlers’ experiences. Findings demonstrate that a moving/paddling body is spontaneously a tactile-kinesthetic/kinetic, emotion-motion and intercorporeal body. These bodily dimensions enrich our understandings of the ways of learning new movements, doing sport and doing sport together.

The phenomenon of movement awareness requires more attention to make it explicit in physiotherapy. The aim of this study was to explore the variation in physiotherapists’ conceptions of movement quality, focusing on movement awareness. The informants were 15 physiotherapists from a variety of physiotherapy fields. We collected data through two group interviews and used the phenomenographic method to analyze them. Four themes emerged from the data: 1) Being in contact with one’s own moving body; 2) Increased awareness of movement experiences; 3) Interrelationship between physiotherapist and patient; and 4) Better understanding of movement awareness. These themes varied by four descriptive categories of the movement awareness phenomenon: (I) Hesitation regarding own movement experiences; (II) Momentary contact with own movement experiences; (III) Presence in movement awareness and (IV) Better understanding of others’ movement awareness. The physiotherapists’ understanding of the movement awareness phenomenon widened through three critical aspects in the descriptive categories: Recognizing one’s own movement awareness, Distinguishing one’s own and others’ movement awareness and New insights into implementing actions related to movement awareness in physiotherapy. These results can expand the understanding of the phenomenon of movement awareness among physiotherapists, although further research is needed. peerReviewed

Dance has become a topic of increasing interest for empirical research in cognitive neuroscience and psychology. The study reviewed in this chapter aimed to reach a multifaceted community of scholars and practitioners interested in the blending between neuroscience and dance as an art form. It includes a revision on dancers’ physical expertise and skilled motor execution, studies on dancers’ timing and online synchronization abilities, and learning and memory processes, as well as a consideration of expert dancers as skilled dance observers. Following the authors’ comment on the article, they acknowledge major developments since its publication, in particular regarding recent lines of research on emotional components of dance, creativity, aesthetic perception, improvisation, entrainment, empathy, and well-being. Finally, the authors emphasize the impact of empirical research in dance beyond cognitive neuroscience and psychology and consider the potential of multidisciplinary expert teams that include the performing arts community to contribute to discourses in the arts and the sciences.

This paper aims to study a degenerate parabolic problem for a solenoidal vector field in which the time derivative acts on a moving body. We propose a fully-discrete finite element scheme combined with backward Euler’s method for the saddle-point variational formulation. The convergence of this numerical scheme is proved and error estimates for some stable finite element pairs are also established.

People speak not only under relaxed conditions but also during strenuous activities, and grammatical resources can be used to achieve displays of strain. This study looks at the relationship between progressivity of talk and bodily strain, focusing on the practice of temporarily suspending syntax while the speaker is accomplishing a physically challenging task. Based on examples from two different physical activities, rock climbing and opera rehearsals, the paper argues that the practice of suspending syntax is a resource available across contexts to render prominence to the strained body and highlight ongoing movement or other bodily action. By placing the strain-based display of incapacity to talk at a moment when the emerging syntactic structure is incomplete, participants maintain rights to resume talk while also presenting themselves as possessing the physical capacity to do so. Suspending syntax is shown to be a minutely timed speakers technique that takes advantage of the emergent nature of syntax and that demonstrates how speakers organize language in relation to the sensing and moving body.

As the main venue for sports training and competition, the thermal environment of a stadium directly could affect the comfort and health of a moving body and sports performance. In this study, the quantitative relationship between ambient temperature and subjective sensation evaluation was established by monitoring the actual thermal sensation evaluation, fatigue sensation cognition and physiological response with high physical activity, under different conditions of ambient temperature. The results show that 90% of subjects can actually accept an ambient temperature range of 18.6°C–26°C. This is 2°C higher than the maximum recommended range in the ISO 7730:2005 thermal comfort standard, reflecting a strong tolerance of the moving human body to low or high temperature environments. A high temperature environment could cause exercise fatigue to occur prematurely. Moreover, the study suggests that the critical point for early occurrence of fatigue sensation in a moving human body is 28°C. The relationship between the environmental temperature and the physiological response was evaluated by mean skin temperature, blood pressure and heart rate of the human body. These are used as evaluation indexes of physiological parameters. Ambient temperature has a significant effect on the objective physiological response of the moving human body, which coincides with the subject’s definition of subjective sensory evaluation to the ambient temperature.

Particle intake by human breathing is important for developing relevant estimates of exposure in the indoor environments; however, relatively few studies are devoted to the influence from human activities. This study evaluates the nasal inhalability of micron particles for a manikin in motion by transient computational fluid dynamics (CFD) simulations. The model was built using a full-scale manikin with key facial features at the nose and mouth. The manikin was moving at a speed of 0.8 m/s through stagnant air in an indoor environment achieved by dynamic mesh. Three nasal inhalation rates of 15, 27, and 40 LPM (litres per minute) and four particle sizes (7, 22, 52, and 82 μm) were considered. The particle intake fraction was calculated to quantify the nasal inhalability of particles over different conditions. Fluid flow field of the motion-induced wake flow and particle trajectories were visualized to reveal the principles of the particle inhalability for a body in motion. This study quantifying the particle intake for a moving manikin will help to characterize a more holistic scenario for respiration modellings and developing estimates of exposure affected by human activities.

Abstract: Current study aimed to investigate student teachers’ understanding for a major concept in science education which is center of gravity and its mathematical and daily life applications. The center of gravity of an object is the point at which mass is equally distributed and all sides are in balance. This concept is useful in designing static structures such as buildings and bridges or in predicting the behavior of a moving body when it is acted on by gravity … etc. To achieve this goal, researchers conducted a conceptual understanding test and a semi-structured interviews with 52 student teachers to collect data about their understanding of center of gravity and its mathematical and daily life applications. Descriptive statistics were used to generate avrages and percentages. The major conclusions drawn from this paper were results regarding students teachers’ understanding for center of gravitiy and its applications is low by comparison with what it should be. For that reason researchers developed a program based on mathematical modeling to develop student teachers’ for center of gravitiy and its applications.

Сomprehension of the concepts: «inertial condition of a body» and «inertial force» is the main aim of the article. Authors consider an inertial condition of a body or a system, as independent, autonomous, self-retaining and only internally dialectically changeable condition of the system living under the internal laws.

This paper investigates how the study of dance and the visibility of the moving body can be used to rethink the conceptualisation of place. Examining the dancing body reveals an unspoken corporeal knowledge that subsists in our engagement with the everyday world, and exceeds our ways of talking or writing about dance as an art form. The body inscribes the space it moves across, leaving trajectories and choreographic lines and, due to its tangibility, also comes to corporeally fill or occupy a place. It is about understanding the movement of bodies in terms of the physical expression of the performer but also from the perspective of an audience, which serves as a third person perspective on corporeal expression. When watching a body move, the observer becomes attentive to the gestures, rhythm, intentionality, and the crowd of virtual movements that accompany it. Through the work of dance theorists such as Rudolf Laban, we examine how the dancing body oscillates between the intentional and the observed in the constitution of the sensual dimensions of space. Most importantly we explore how dance shifts the point of focus away from place as a locale to place as a site of corporeal witnessing.

The mathematical model of nonlinear oscillations of an elastic moving one - dimensional body is investigated. The method of research of the specified model in case of resonant and nonresonant modes of fluctuations is developed. The oscillatory systems considered in the work simulate, in particular, dynamic processes in auger electromechanical machines, technological equipment used in drilling works, etc. The equations in standard form, which determine the parameters of the dynamic process for nonlinear oscillations of a moving body, are considered and investigated. Asymptotic approaches to the study of these mathematical models of oscillations make it possible to obtain and analyze the conditions of resonant and non-resonant modes of operation of the above technological systems.

Sport, Physical Culture and the Moving Body is an important collection that will underpin and inform several perspectives and engagements-to-come with sport, leisure and physical culture. This volume meaningfully captures and expands the momentum created by feminist scholars who in the last decade have underlined the relevance of more-than-human theoretical orientations in addressing the domains of sport and leisure. In doing so, the book sets out a number of questions and domains\ud of enquiry that push the boundaries of sport and leisure scholarship and provide meaningful lines of flight in approaching the material-discursive entanglements that weave together bodies, technologies and ecologies. The breadth of topics addressed in the collection surely makes this book\ud a go-to resource for post-graduate students and for scholars across the fields of leisure, sport and physical cultural studies. However, while advancing exciting domains of enquiry, this anthology also leaves open some important questions and gaps. In this review, I briefly underline two issues that I contend are particularly relevant for more-than-human analyses of sport, leisure and physical culture.

Problem statement: in this article the essence of the symbiotic robot “Triangel” based on SEMS which comprises in its mechanical union with the patient’s body and with a single coordinate system, is shown. As a result, the symbiotic robot “Triangel” is able to perform massage manipulations of the patient’s back or chest not only in the passive position of the body, but also on the moving body, regardless of its spatial orientation. Also the patient can simultaneously massage its chest and back by two symbiotic robots “Triangel”. The symbiotic robot “Triangel” can function both autonomously and under the remote supervision of a massage therapist via the Internet. However, when moving the patient during the massage with the help of a symbiotic robot “Triangel”, he may fall, for example, tripping, slipping or as a result of loss of consciousness. Purpose of research: development of algorithms for decision-making by the symbiotic robot “Triangel” after a patient falls to the surface. Results: possible types of patient falling to the surface and their classification are shown. The decision-making model axiomatics and the algorithms developed on its basis for decision-making by single or two symbiotic robots “Triangel” installed simultaneously on the patient’s chest and back are presented. The decision-making algorithms are formed depending on the patient’s condition, for example in the following cases: the patient is conscious and does not need help; the patient is conscious and needs help; the patient is unconscious; the patient has died. Practical significance: decisions-making by the symbiotic robot “Triangel” both autonomously and under the remote control of the massage therapist in real time via the Internet will reduce the risk of a threat to the patient’s health or life after falling to the surface during the massage.

We show existence and uniqueness of regular time-periodic solutions to the Navier–Stokes problem in the exterior of a rigid body, \(\mathcal B\), that moves by arbitrary (sufficiently smooth) time-periodic translational motion of the same period, provided the size of the data is suitably restricted. Moreover, we characterize the spatial asymptotic behavior of such solutions and prove, in particular, that if \(\mathcal B\) has a nonzero net motion identified by a constant velocity \(\overline {\boldsymbol {\xi }}\) (say), then the solution exhibits a wake-like behavior in the direction \(-\overline {\boldsymbol {\xi }}\) entirely analogous to that of a steady-state flow around a body that moves with velocity \(\overline {\boldsymbol {\xi }}\).

Gross motor development is inferred from assessments measuring competence in specific motor skills involving the large and small muscle groups. Age shows the most consistent relationship (positive) with all aspects of motor competence, regardless of how competence is defined. Additionally, children scoring higher on global scores of motor competence tend to be more physically active and weigh less than those with lower scores. Competence and development of the gross motor skills and balance characteristics can be assessed using a variety of assessments depending on whether the goal involves product outcomes (e.g., speed, hitting a target, balancing time) or process qualities (e.g., quality of moving body segments). Process assessments include the Test of Gross Motor Development and the Children’s Activity and Movement in Preschool Study Motor Skill Protocol. The chapter also discusses some product assessments such as the Movement Assessment Battery for Children and the Peabody Developmental Motor Scales.

Our study aimed to analyze movement control strategies using predefined criteria for amplitude and differences in these strategies between children with and without DCD. Children with (n = 28) and without DCD (n = 15) were included. A video-observation-tool was used to score the moving body parts during a Wii Fit slalom task over multiple time points. Two-step cluster analysis was used to extract distinct movement strategies. Two different movement strategies were identified that were independently validated by a measure of task performance and a subjective mark of quality of the movement. Initial differences between groups and changes over time toward the more successful strategy were found in both groups, albeit in a different percentage. This study shows that the more efficient movement strategy is seen in the majority of the TD children and only in a small number of children with DCD, even after practice.

The moving-coordinate method presented by the authors is a method for computing flows about the moving body, where the coordinate systems are attached to individual moving bodies, so that each body could stand still with stationary grid. Here, as numerical methods for flows including moving boundaries, first, a review is given about the conservative form in general coordinates with implication of geometric conservation laws and the ALE (Arbitrary Lagrangean–Eulerian) formulation, to show that the governing equations are derived from the former to the latter systematically. Then, the moving-coordinate method is derived. From the perspective given above, the advantages and disadvantages of this method are discussed. Finally, applications confirmed availability of the moving-coordinate method.

This experimental study examines ventilated supercavity formation in a free-surface bounded environment where a body is in motion and the fluid is at rest. For a given torpedo-shaped body and water depth ($H$), depending on the cavitator diameter ($d_{c}$) and the submergence depth ($h_{s}$), four different cases are investigated according to the blockage ratio ($B=d_{c}/d_{h}$, where$d_{h}$is the hydraulic diameter) and the dimensionless submergence depth ($h^{\ast }=h_{s}/H$). Cases 1–4 are, respectively, no cavitator in fully submerged ($B=0$,$h^{\ast }=0.5$), small blockage in fully submerged ($B=1.5\,\%$,$h^{\ast }=0.5$), small blockage in shallowly submerged ($B=1.5\,\%$,$h^{\ast }=0.17$) and large blockage in fully submerged ($B=3\,\%$,$h^{\ast }=0.5$) cases. In case 1, no supercavitation is observed and only a bubbly flow (B) and a foamy cavity (FC) are observed. In non-zero blockage cases 2–4, various non-bubbly and non-foamy steady states are observed according to the cavitator-diameter-based Froude number ($Fr$), air-entrainment coefficient ($C_{q}$) and the cavitation number ($\unicode[STIX]{x1D70E}_{c}$). The ranges of$Fr$,$C_{q}$and$\unicode[STIX]{x1D70E}_{c}$are$Fr=2.6{-}18.2$,$C_{q}=0{-}6$,$\unicode[STIX]{x1D70E}_{c}=0{-}1$for cases 2 and 3, and$Fr=1.8{-}12.9$,$C_{q}=0{-}1.5$,$\unicode[STIX]{x1D70E}_{c}=0{-}1$for case 4. In cases 2 and 3, a twin-vortex supercavity (TV), a reentrant-jet supercavity (RJ), a half-supercavity with foamy cavity downstream (HSF), B and FC are observed. Supercavities in case 3 are not top–bottom symmetric. In case 4, a half-supercavity with a ring-type vortex shedding downstream (HSV), double-layer supercavities (RJ inside and TV outside (RJTV), TV inside and TV outside (TVTV), RJ inside and RJ outside (RJRJ)), B, FC and TV are observed. The cavitation numbers ($\unicode[STIX]{x1D70E}_{c}$) are approximately 0.9 for the B, FC and HSF, 0.25 for the HSV, and 0.1 for the TV, RJ, RJTV, TVTV and RJRJ supercavities. In cases 2–4, for a given$Fr$, there exists a minimum cavitation number in the formation of a supercavity while the minimum cavitation number decreases as the$Fr$increases. In cases 2 and 3, it is observed that a high$Fr$favours an RJ and a low$Fr$favours a TV. For the RJ supercavities in cases 2 and 3, the cavity width is always larger than the cavity height. In addition, the cavity length, height and width all increase (decrease) as the$\unicode[STIX]{x1D70E}_{c}$decreases (increases). The cavity length in case 3 is smaller than that in case 2. In both cases 2 and 3, the cavity length depends little on the$Fr$. In case 2, the cavity height and width increase as the$Fr$increases. In case 3, the cavity height and width show a weak dependence on the$Fr$. Compared to case 2, for the same$Fr$,$C_{q}$and$\unicode[STIX]{x1D70E}_{c}$, case 4 admits a double-layer supercavity instead of a single-layer supercavity. Connected with this behavioural observation, the body-frontal-area-based drag coefficient for a moving torpedo-shaped body with a supercavity is measured to be approximately 0.11 while that for a cavitator-free moving body without a supercavity is approximately 0.4.

Quando discutido para além dos determinismos biofisiológicos, o corpo mostra-se um objeto valioso de estudo, embora ainda sejam discretas ações a esse respeito. Com isso, indaga-se quais são as constituições corporais estabelecidadas pelo catolicismo brasileiro, uma vez que as religiões possuem em seu amálgama a busca pela organização da experiência nômica humana por meio da oferta e da difusão de estruturas de legitimação e plausibilidade, que constroem um cosmo coeso. Para tanto, foi realizada uma pesquisa de bases etnográficas com os católicos da comunidade tricentenária de Brumal (MG), buscando-se observar as diferentes constituições corporais e os diferentes usos do corpo durante as manifestações dessa comunidade de fé. Do mesmo modo, procedeu-se à seis entrevistas com moradores da localidade, maiores de 18 anos e de ambos os sexos. Nessa perspectiva, constatou-se que o corpo em movimento assume, nos diferentes momentos instituídos por tal solução sacral, maneiras de o católico viver e se situar em relação ao sagrado.

European psychosomatics, as a branch of psychoanalytic psychopathology, has existed for almost two centuries, but it is a constantly moving body of thought. From epistemology to aetiology, its questions are still evolving and concern the debate between the psyche/soma dualism and the monistic alternative, but also the psychic meaning that is to be attributed to somatic symptoms. In France, the discipline has not had its last word, for it is constantly seeking to position itself as a field of research and clinical practice within psychoanalysis. However, it still needs to affirm itself and open itself more towards other branches of knowledge, such as medicine, neuroscience, or the social sciences. In this context, are the processes of somatisation still to be thought of as boundary objects for psychoanalysis? On what epistemological, theoretical, methodological, and practical conditions is the psychosomatic question still or at last possible? In particular, is it possible to reintroduce the question of the "meaning" of the somatic phenomenon in order to breathe new life into it, without returning, however, to the symbolic interpretation of symptoms, while preserving the subjectivising approach of psychoanalysis and its logic of interpolation? Can we speak in the human sciences of a truly psychosomatic revolution in the image of psychoanalytic advances?
