Sport Has Never Been Modern
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Sport has often been understood as a set of formalised physical contests, and moreover as something inherently modern. New conceptions of the term implicates that sport ought to comprise all physical activity. However, the studies and approaches that describe the range and tension between those positions are lacking. The thesis addresses this lacuna and suggests that the aforementioned conceptions could be inquired as the narrow (physical contest) and the broad (physical activity) understanding of sport. The work presented in this thesis sets out to outline a theoretical and methodological framework that could comprise the different conceptions of sport. This framework is laid out with inspiration from Bruno Latour’s symmetrical anthropology. The empirical material was collected from an array of sources with a broad range of ethnographical methods. Four sporting practices (break time football, parkour, eSport, and company table tennis) that embody the tension between the broad and the narrow are inquired into in the articles. The comprehensive framework that the thesis seeks to outline takes form in shape of the different concepts (“dromography,” “minor sport,” and “the art of tracing”) constructed within the articles. It is concluded that the broad understanding of sport threatens to hollow the term. However, the narrow understanding of sport tends to downplay the material dimension of modernity. It is argued that the connection between the material and the social dimension of sport, with regards to categories such as age and gender, mustn’t be neglected in the study of sport. Furthermore, it is argued that the competitive element of modern sport is related to modern science in an unexpected way that adds new understanding to the ontology of modernity in general.

Education for sustainable food consumption in home and consumer studies : Lärande för hållbar matkonsumtion i hem- och konsumentkunskap
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Education as a means to enable sustainable food consumption has gained increasing recognition as a vital means to decrease current burdens upon both natural resources and human health. In response, the Swedish compulsory school subject of home and consumer studies, which positions education about food as core content, has been revised to incorporate in its national syllabus a perspective of sustainable development since 2011. However, because sustainable development remains an ambiguous, contested concept with a range of definitions and interpretations, it is necessary to gain better understanding of what incorporating its perspective can entail in home and consumer studies, particularly regarding the core food-related content knowledge that it teaches. Building upon four papers, this thesis reports research guided by an interpretive and exploratory approach that involved analysing data from syllabuses, observations, recordings of in-class lessons and interviews with practising teachers. The results reveal two ways of understanding what incorporating a perspective of sustainable development can entail in home and consumer studies in Sweden. The first understanding proposes an enriched and unified practice in which the curriculum prioritises embodied forms of knowledge about healthy, ethical and resource-efficient food consumption by allowing a multi-relational, systems thinking approach while focusing a homemade meal practice. By contrast, the second understanding proposes a practice riddled with inconsistencies and contradictions in providing teaching and learning opportunities to attain the intended goals. This ultimately results in fragmented learning opportunities focused more on informed reasoning than on informed actions. Taken together, both understandings pose theoretical, conceptual and practical implications, both for home and consumer studies in particular and in education for sustainable food consumption in general.

Hälsocoach i skolan - En utvärderande fallstudie av en hälsofrämjande intervention
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Today young school children in Sweden spend less time taking part in physical activities, compared to what they did 15-20 years ago. Physical activity is a major health component, which can make children maintain or increase their health. Earlier research has shown that a minimum of 60-90 minutes a day of physical activity is needed for young children to develop good health. The purpose of this study is to explore a longitudinal (two years) health coach intervention, focusing on the effects and experiences of expanded physical activities in an elementary school, managed by a health coach. The research team planned the health coach intervention based on the theoretical model; Youth Physical Activity Promotion Model (YPAPM). In the study, quantitative and qualitative data have been collected over a period of two years. Analysis has shown that the health promotion activities attracted even those children who usually do not like the PE classes. These children like playful activities where they can feel athletic competent and involved. The Health Coach project did not significantly improve the students' healthy lifestyles, at least not in the short term, even if the children had gained new insights about how to promote their own health. This study has shown that a health coach in school could be needed, but this position needs to be full-time, because it requires more efforts to increase children's physical activity. It is also important that the health coach has the right qualification and receive support from the head master and from the class teachers.

Idrotten sätter agendan : En studie av Riksidrottsgymasietränares handlande utifrån sitt dubbla uppdrag
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This study aims to describe and analyse the actions of the school coaches at the National sport upper secondary schools in light of the conditions that govern and shape the activities at those schools.The theoretical standpoints are based on Lave and Wengers' (1991) theoretical concept community of practice, and as an explanatory theoretical framework Scott's (2008) interpretation of new institutional theory is used. In the analysis of the coaches’ space for actions given the current conditions, Berg's (2014) free space theory is used.The study has a qualitative approach and the design is based on four case studies, where interviews and document analyses have been used to produce the data.The main findings can be summarized in that the cultural-cognitive conditions are very strong, whereas the regulatory and normative conditions play a less significant role. The coaches belong to a community of practice, where the sport’s inherent culture becomes the reference point for how the practice will be run, even though they are part of the school.

Physiological responses to acute physical and psychosocial stress- relation to aerobic capacity and exercise training.
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Exercise training is an effective method to promote health and to prevent development of disease. Both physical and mental health have been shown to benefit from exercise training. It has also been speculated that physical exercise might affect responses to acute psychosocial stress. In an acute stress situation, several physiological systems respond to ensure survival and it is suggested that exercise training may influence these stress systems. The main purpose of this thesis was to study physiological responses to acute physical and psychosocial stress and possible associations with aerobic capacity and exercise training. The thesis is based on four papers analysing data from a randomized controlled trial (RCT). The participants were healthy individuals who reported themselves as untrained at screening. The RCT included testing of acute physical and psychosocial stress. Before and after the tests, hormonal and autonomic responses were assessed. After initial testing, the participants were randomized to either an intervention- or a control group. The intervention consisted of regular aerobic exercise training conducted for six months. At follow-up, the same tests were repeated for both groups. The main findings were that most participants showed an increase in the studied variables in response to acute stress. Aerobic capacity did not seem to have any relation to hormonal or blood pressure responses to acute psychosocial stress. Neither did the subjective perception of stress at the psychosocial stress test correlate with the actual physiological response. Due to methodological issues, it was not possible to evaluate the effects of exercise training. Thus, in healthy individuals, the stress systems seem to respond adequately to acute stress, irrespective of level of aerobic capacity or type of stressor.

Lärande av rörelseförmåga i idrott och hälsa ur ett praktikutvecklande perspektiv : Movement capability. Development of teaching practice in physical education and health
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this investigation was to explore how the connections between teaching and learning about movement capability in the school subject physical education and health can be developed and transferred through research in practice development. Three research questions guided the investigation (1) What areas regarding teaching of movement capability in the school subject physical education and health have been studied in relation to teachers’ teaching assignment? (2) What necessary prerequisites are required to systematize and transfer research in practice development on movement capability between educational contexts? (3) What linkages are made visible between the treatment of learning content, the teaching design and students’ learning through variation in lesson design? Cultural-historical perspective and variation theory were used as frameworks and the methodology, mixed method research. The empirical data consists of published articles, video-observed lessons, recorded meetings with teachers and students, pre- and post-tests. The findings position the thesis in a guided teaching perspective. Moreover, findings show how the connection between teaching and learning about movement capability systematically can be developed and transferred between teaching contexts through iterative processes with revised lessons based on students’ knowledge. By the use of variation theory, understanding of the meaning of movement capability became more nuanced and itemized. The results also illustrate how the collaboration between teachers and researchers generated development of science-based teaching of movement capability.

Game demands and fatigue profiles in elite football – an individual approach -Implications for training and recovery strategies
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The physical activities performed during a football game are of intermittent prolonged character, including explosive actions and running at different speeds. The prolonged intermittent activities are conjoined with periods where physical intensity is markedly increased. The intense periods and prolonged activities affect the physiological and metabolic systems which provoke fatigue both temporarily throughout the game as well as towards the end of a game. Therefore, physical training in football should aim to reach physiological and metabolic adaptations to be able to resist fatigue in order to perform optimally throughout the game. Furthermore, post-game recovery and restoration of performance seems to be a slow process. Physical game demands, training responses and recovery can vary largely between players and needs to be studied with individual emphasis. The aim of the thesis is to improve the understanding of physical game demands, fatigue profiles in male elite football players with an emphasis on individual differences and implications for fitness training strategies. Running distance and in-game fatigue profiles were investigated through an analysis of game activity data from top-class football players (n = 473). Post-game fatigue and recovery profiles were examined using maximum voluntary contraction in various muscle groups after a simulated football model in competitive players (n = 12). Inter-individual relations between physical game demands and physical response in different small-sided game formats were investigated with global positioning system techniques on professional players (n = 45). Finally, muscular adaptations and physical performance responses of two different training protocols (four weeks of small-sided games or speed endurance training) were examined by means of pre- and post-intervention muscle biopsies and performance tests on 39 competitive football players. The results demonstrated that all playing positions indicate temporary fatigue after intense periods during a football game. However, after shorter intense periods central defenders were the only position that did not show a decline in running performance. A large inter-player variation in running performance between and within playing positions was found. Post-game fatigue showed large inter-player differences between various muscle groups and between players. Muscle performance in all investigated groups had recovered within 24 hours post-game except trunk-muscles, which was back to baseline values within 48 hours post-game. The physical response in small-sided game formats differed from game demands on an individual level. High intensity training was more potent in up-regulating muscle oxidative capacity and physical performance compared to small-sided games. In conclusion, individual differences in game demands and fatigue profiles are large and need to be considered when planning training. Small-sided games seem not to be the most appropriate training method to meet the individual game demands of all individual players. Thus, in order to increase exercise performance and associated physiological adaptations, additional high-intensity training should be considered for some individual football players.

Food, body weight, and health among adolescents in the digital age: An explorative study from a health promotion perspective
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis was to explore adolescents’ relationship with food, body weight, and health communication in online digital media, as well as how adolescents experience participating in a health promotion intervention regarding food and physical activity habits. Health promotion as a research area served three purposes: to inform the research questions, to direct the data collection, and to identify implications from the research findings. The four included studies explored how adolescents portray food in a widely used image-sharing application, why and how adolescents in treatment for obesity engaged with online health-related information, and how these adolescents experienced presenting themselves on social media. The fourth study explored adolescents’ experiences of participating in a health promoting intervention, focusing on their experiences of using a social media group within the intervention. Overall, the findings suggest that food is a significant means of adolescents’ online self-presentation practices. Food imagery was most often communicated in a positive way, associated with commercial elements, and often depicting high-calorie foods. Adolescents with obesity experienced this user-generated food content as challenging for their weight management. These findings also question the separation between media and information content as stated in the original definition of eHealth literacy. The findings also emphasize a need to explore the adolescents’ own experiences of acceptability of using social media in health promotion practices, with regards to the type of social media and in what context it was or could be used.

An empowerment-based school physical activity intervention with adolescents in a disadvantaged community: A transformative mixed methods investigation
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- It is important for the health of adolescents to engage in regular physical activity. The majority of adolescents do not, however, engage in sufficient physical activity to meet contemporary guidelines, and adolescents of low socioeconomic status appear to be less physically active compared to adolescents of high socioeconomic status. As such, the overall aim of this thesis is twofold. First, the thesis aims to gain insight into adolescents’, from a multicultural community of low socioeconomic status, views on physical activity. Second, the thesis aims to describe and problematize the development and implementation of an empowerment-based school intervention, in a Swedish multicultural community of low socioeconomic status, and to evaluate the effects of the intervention focusing on basic needs satisfaction, motivation, and objectively measured physical activity. This compilation thesis is based on four papers and is written within the ‘How-to-Act?’-project which has its starting point in a two-year empowerment-based school intervention. For the purpose of the ‘How-to-Act?’-project, one intervention school (n=54 7th graders) and two control schools (n=60 7th graders), situated in a multicultural area of low socioeconomic status in Gothenburg, were recruited. For paper I and II, focus group interviews were conducted with adolescents (n=53) in the intervention school, before implementation of the intervention, to illuminate what they convey concerning factors that facilitate respectively undermine their physical activity. Paper III describes and problematizes the development and implementation of the empowerment-based school intervention, which was continuously developed and implemented through cooperation and shared decision making, focusing on physical activity. For paper IV physical activity was measured with accelerometers and basic needs satisfaction and motivation through questionnaires at baseline (7th grade), midpoint (8th grade), and endpoint (9th grade), to evaluate the effects of the intervention. On the one hand, the adolescents’ voices illuminated that, within their environment, it is difficult to establish healthy physical activity habits. More specifically, the adolescents expressed a profound awareness of tempting screen-based activities as undermining their physical activity, and several stereotypical gender norms were highlighted as undermining the girls’ physical activity. On the other hand, the adolescents mentioned that they enjoyed engaging in physical activity. According to the adolescents, enjoyment related to physical activity was promoted through variation and options, experiencing and developing physical skills, and the presence of peers. The adolescents also suggested that social support facilitated their physical activity, and proposed some ideas on how the school could become more supportive of their physical activity. Through the empowerment-based school intervention, the adolescents were offered opportunities to engage in a variety of physical activities and to assess and critically reflect upon health-related information and recommendations. Further, the intervention involved the adolescents in the decision-making process and thus, arguably, facilitated participation and empowerment. Nonetheless, the development and implementation of the intervention led to a number of ethical dilemmas that required cautious consideration. During the course of the two-year intervention, there was a credible decrease in controlled motivation, autonomous motivation, and moderate-to-vigorous physical activity. There were no credible effects of the intervention on controlled motivation, autonomous motivation, or moderate-to-vigorous physical activity. Future school-based physical activity interventions, in multicultural areas of low socioeconomic status, are recommended to include multidimensional intervention approaches across contexts to counteract the decline in physical activity during adolescence and to achieve lasting change in adolescents’ physical activity.

How to Make Bicycling Safer - Identification and Prevention of Serious Injuries among Bicyclists
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis was to guide current and future safety improvements that address serious injuries among bicyclists. The thesis is compiled by four studies, of which the first two aimed to identify injuries leading to loss of health from a biopsychosocial perspective, and the two following studies aimed to understand how these injuries occur and how they can be prevented. Study I investigated health-related quality of life (HRQoL), based on the EQ-5D questionnaire, while Study II investigated sickness absence (SA), following a bicycle crash. On a general level, the injuries associated with problems in HRQoL and long-term SA included mainly fractures of the hip and upper leg, fractures of the lower leg and ankle, fractures of the upper arm, fractures and sprains of the shoulder, traumatic brain injuries, and fractures and strains to the spine. Study III found that the majority (68%) of such injuries occurred in single bicycle crashes, and further 17% in collisions with motor vehicles. In Study IV it was shown that the current Swedish safety performance indicators related to cycling could address up to 22% of crashes involving injuries associated with problems in HRQoL and long term SA. In addition to the current safety performance indicators, the following five actions should be the focus of more rapid implementation: autonomous emergency braking with cyclist detection on passenger cars, extended maintenance to include all urban roads used for cycling, improved design of curbstones, and to separate cyclists from both motor vehicles and pedestrians. Overall, this thesis highlights that additional interventions targeting single bicycle crashes need to be prioritised by road authorities in order to prevent health loss among bicyclists.
