- Background Long outdoor stay may cause hazardous exposure to ultraviolet radiation (UVR) from the sun even at high latitudes as in Sweden (Spring to Autumn). On the other hand, long outdoor stay is a strong predictor of primary school children ' s free mobility involving moderate to vigorous physical activity (MVPA). UV-protective outdoor environments enable long outdoor stay. We investigated the concurrent impact of different school outdoor play settings upon pupils ' sun exposure and levels of physical activity across different ages, genders, and seasons. Method During 1 week each in September, March, and May, UVR exposure and MVPA were measured in pupils aged 7-11 years. Erythemally effective UVR exposure was measured by polysulphone film dosimeters and MVPA by accelerometers. Schoolyard play was recorded on maps, and used areas defined as four play settings (fixed play equipment, paved surfaces, sport fields, and green settings), categorized by season and gender. Results During the academic year, sport fields yielded the highest UVR exposures and generated most time in MVPA. In March, time outdoors and minutes in MVPA dropped and UVR exposures were suberythemal at all play settings. In May, green settings and fixed play equipment close to greenery promoted MVPA and protected from solar overexposure during long outdoor stays. Conclusion More outdoor activities in early spring are recommended. In May, greenery attractive for play could protect against overexposure to UVR and stimulate both girls and boys to vigorous play.

Tidskriftsartikel (refereegranskat)abstract
- Background: Given the significance of motor competence (MC) for healthy development and as a cornerstone for lifelong physical activity (PA), it is crucial to understand the manifold factors that are associated with MC. Thus, the aim of the present study was to investigate correlates of children's MC and their fundamental movement skills (FMS) within their daily life from a comprehensive biopsychosocial-ecological perspective. Methods: This is a cross-sectional sub-study of the 'Physical Literacy for Communities (PL4C)' WAVES cohort study conducted in the West Vancouver School District, Canada. Motor competence was assessed using the PLAYfun tool including overall MC score and five FMS category scores, namely, running, locomotor skills, upper and lower body control and balance skills. By means of structural equation modeling (SEM), direct associationswith MC and with the specific FMS categories addressing physical activity behavior, self-perceived physical literacy, parenting, and school ground design were investigated. Results: A total of 355 children with a mean age of 7.5 years and 111.1 min of MVPA per day participated. The group comprised 51% boys and 47% girls from 14 elementary schools. Most children were at an emerging MC-level (71%), while those at a competent MC-level exhibited significantly more daily minutes of MVPA (123 versus 109, p = 0.001). Additionally, they played outdoors more frequently and engaged in more instructor-led PA. The results revealed that logistical support from parents had not only a direct positive association with overall MC, both for girls and boys, but also with most of the FMS categories. However, the correlates of MC varied between genders and showed different patterns across the five FMS categories. While time spent in sports or coach-/instructor-led physical activities had a significant SEM generated direct effect only for boys' MC and for locomotor, upper body object control and balance, the aesthetic design of the school grounds was only associated with girls' MC and those same three FMS categories. Multivariate SEM could explain 26% of variance for girls' MC and 30% for boys'. Conclusions: This exploratory baseline assessment revealed parental logistical support as an important correlate of MC, irrespective of gender. There were distinct gender patterns across biopsychosocial-ecological correlates influencing MC and FMS. Despite the heterogeneity of the results, our findings indicate a potential role of school ground design in supporting the development of children's MC, especially for girls.

Tidskriftsartikel (refereegranskat)abstract
- Background: Several studies have estimated the health effects of active commuting, where a transport mode shift from car to bicycle reduces risk of mortality and morbidity. Previous studies mainly assess the negative aspects of bicycling by referring to fatalities or police reported injuries. However, most bicycle crashes are not reported by the police and therefore hospital reported data would cover a much higher rate of injuries from bicycle crashes. The aim of the present study was to estimate the effect on injuries and fatalities from traffic crashes when shifting mode of transport from car to bicycle by using hospital reported data. Methods: This present study models the change in number of injuries and fatalities due to a transport mode change using a given flow change from car to bicycle and current injury and fatality risk per distance for bicyclists and car occupants. Results: show that bicyclists have a much higher injury risk (29 times) and fatality risk (10 times) than car occupants. In a scenario where car occupants in Stockholm living close to their work place shifts transport mode to bicycling, injuries, fatalities and health loss expressed in Disability-Adjusted Life Years (DALY) were estimated to increase. The vast majority of the estimated DALY increase was caused by severe injuries and fatalities and it tends to fluctuate so that the number of severe crashes may exceed the estimation with a large margin. Conclusion: Although the estimated increase of traffic crashes and DALY, a transport mode shift is seen as a way towards a more sustainable society. Thus, this present study highlights the need of strategic preventive measures in order to minimize the negative impacts from increased bicycling. (C) 2016 Elsevier Ltd. All rights reserved.

- Influence and the opportunity to have one’s voice heard are fundamental rights valid for all people, including also children and youths. Despite this, research shows that young people’s voices have received less attention and young people have no influence in many contexts in which they find themselves (Evans, 2007; Fundberg, 2009; Redelius, 2005). In Sweden, the emphasis on influence can be linked to the fact that the sport club activities of the Swedish state are seen as an important arena for the civic education of young people (The Swedish Sports Confederation, 2005, 2011). The aim of this study is to explore young coaches and their opportunities to influence in the Swedish sport clubs with focus on what the youths themselves say about influence and power. We use Bourdieus’ theories on social fields to bring to light which youths are chosen to be leaders and their possibilities to influence. The results show that for young coaches to have influence, both their habitus and capital are required to ‘match’ the social context into which they are entering. One way of maintaining power is not to change the accepted way of working, which excludes the young coaches from challenging in the battle for positions.

- ‘Characteristics and consequences of different body ideals’ are a mandatory curriculum content in Swedish physical education (PE). Didactic strategies for teaching on body ideals are, however, scarce. In this paper, we introduce a classroom-based teaching unit on body ideals and present didactic possibilities and challenges of the unit. We used a lesson study approach, drawing on Nutbeam’s concept of health literacy. Our methodology involved focus group interviews with students and teachers, lesson observations and minutes of meetings which we analysed thematically. We found teaching on body ideals to be highly meaningful to students but their engagement differed based on personal backgrounds, school context and didactic design. The gendered nature of body ideals and a lack of embodied didactics constituted challenges, while the use of storied cases emerged as a potent didactic strategy. We conclude with practical recommendations for teaching on body ideals in PE.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of the current study was to investigate how combinations of different epoch durations and cut-points affect the estimations of sedentary time and physical activity in adolescents. Accelerometer data from 101 adolescents were derived and 30 combinations were used to estimate sedentary time, light, moderate, vigorous, and combined moderate-to-vigorous physical activity. Data were analyzed with repeated measurement analyses of variance. Large differences of sedentary time and times of different physical activity intensities were observed between 1 s and longer epoch durations using virtually all cut-points. Generally, sedentary time, moderate physical activity, vigorous physical activity, and combined moderate-to-vigorous physical activity progressively decreased, whereas light physical activity increased with longer epoch durations. The extreme differences between cut-points were large and increased with longer epoch durations for sedentary time and for all physical activity intensities except for vigorous physical activity per epoch duration. Caution is required when cross-comparing studies using different epoch durations and cut-points. To accurately register adolescents’ spontaneous intermittent physical activity behavior, short epoch durations are recommended.

Neck muscle function in individuals with persistent pain and disability after whiplash injury
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Neck pain and disability are common after whiplash injury. One year after the accident up to 50 % still have symptoms called whiplash associated disorders (WAD). Despite decades of research the cause of persistent pain and disability are largely unknown and effective treatment and diagnostic tools are lacking. Altered neck muscle function may cause pain and disability, and real-time non-invasive methods that investigate both superficial and deep neck muscle function need to be evaluated.Aim: The general aim of the work presented in this thesis was to investigate mechanical neck muscle function and evaluate effects of three different exercise interventions related to neck muscle function in individuals with persistent pain and disability after whiplash injury.Method: The thesis comprised two studies, reported in four papers. Study A was a prospective randomized controlled trail with 216 participants. The effects of three exercise interventions; neck-specific exercises, neck-specific exercises with behavioral approach and prescription of physical activity were evaluated. Neck muscle endurance, perceived pain following testing, kinesiophobia and satisfaction with treatment were compared between the three groups (paper I). Study B was an experimental case-control study with participants consecutively recruited from the randomized controlled trial. Deformation and deformation rates in the neck muscles were investigated with real-time ultrasound imaging during ten repetitive arm elevations (paper II-IV). To investigate ventral neck muscles, 26 individuals with WAD were compared with 26 healthy controls (paper II). The dorsal neck muscles were investigated in paper III, including 40 individuals with WAD and 40 controls. In total 46 individuals, 23 with WAD and 23 healthy controls were included in paper IV to develop ventral neck muscle interaction models.Results: Paper I: Participants in the two neck-specific exercise groups (with and without behavioral approach) showed increased dorsal neck muscle endurance (p = 0.003), decreased pain intensity following testing (p = 0.04) and were more satisfied with treatment (p < 0.001) than participants in the prescribed physical activity group. Kinesiophobia did not significantly differ between groups (p > 0.12).Paper II: Deformation and deformation rate showed linear positive relationship between ventral muscle pairs in healthy controls, especially between superficial and deep neck muscles. This relationship was weaker or absent in the WAD group.Paper III: The WAD group had higher deformation rates in the deepest dorsal neck muscles during the first and tenth (only women) arm elevations compared to the control group (p < 0.04). Women in the WAD group showed a weaker linear relationship between the two deepest dorsal neck muscles compared to women in the control group.Paper IV: The results revealed two different ventral neck muscle models in individuals with WAD and healthy controls (R2Y = 0.72, Q2Y = 0.59). The models were capable to detect different neck muscle interplay in people with WAD.Conclusion: Neck-specific exercise intervention with or without a behavioral approach appears to improve neck muscle endurance in individuals with persistent WAD. Decreased pain after the neck muscle endurance test also suggests improved tolerance of load in these two groups. Altered mechanical neck muscle function was revealed in individuals with WAD indicating decreased muscular support for maintain a stable cervical spine during repetitive arm elevations. The results show great promise for improved diagnosis of neck muscle function in WAD.

- Research question and purpose: Les Mills is a New Zealand-based fitness distributor with a community consisting of approximately 140.000 instructors worldwide who teach standardized workout routines. This paper aims to explore how the COVID-19 pandemic and related measurements, such as social distancing affect the everyday lives and professions of Les Mills International (LMI) group fitness instructors. The aim was met with the following research questions: RQ1: How are social distancing and social connectedness understood, and how do they condition LMI instructors' understanding of their profession? RQ2: What do LMI instructors think about the #LesMillsUnited campaign to maintain a strong trainer community in the midst of the pandemic? RQ3: How do LMI instructors think that group fitness will change long term due to social distancing? Research methods: Using qualitative measures and a case-study-based approach, data were gathered through interviews with LMI-certified group fitness instructors. Seven semi-structured focused group discussions with fifteen group fitness instructors from different countries were conducted and audio recorded. The first round of virtual discussions took place in April 2020, and the follow-up talks in September 2020. A thematic analysis was employed to analyze the material. Results and findings: According to the participants, online classes as a means of upholding group fitness in times of social distancing is an insufficient substitute to face-to-face instructing, lacking social connectedness that is normally maintained through successful rituals or social scripts. Navigating "instructorhood" during the pandemic includes emotional labor where not only relationships to clients are challenged, but instructors also experience societal pressure to reinvent themselves as instructors. Implications: With no way of telling how long social distancing needs to be practiced, the group fitness industry is facing unprecedented challenges. Making sense of the group fitness profession currently preoccupies instructors who may now have to redefine to themselves how they can teach, and who for.

Tidskriftsartikel (refereegranskat)abstract
- Background Most injuries in track and field are caused by overuse with conflicting reports concerning the underlying mechanisms. The purpose of this study was to evaluate how biomechanical and clinical factors relate to the risk of overuse injuries, and to investigate whether the relationships between potential risk factors and injury become stronger if injuries are grouped by location. Methods The study is a prospective cohort study conducted during a Swedish track and field season over eleven months, from October to August. The cohort consisted of elite male and female track and field athletes competing in either middle- and long-distance running, sprinting, jumping, or throwing events (n = 96). Athletes performed a baseline screening at enrollment consisting of a clinical examination, running, and strength tests. Injury data was collected during the season by medical professionals and divided according to their anatomical location into upper-body, thigh/hip, knee, or foot/shank injuries. Results Thirty-four (54.8%) injuries where located at the foot/shank, followed by sixteen injuries at the thigh/hip (25.8%). Only eight knee (12.9%) and four upper-body (6.5%) injuries were registered during the season and therefore not analysed. Effect sizes were calculated for all test variables. Small effect sizes (r(pb) = .10-.23) were found for eleven risk factors between the overall injured (all injuries combined) and non-injured athletes. By further sub-grouping the injured group into thigh/hip injuries, effect size increased in hip adduction range of motion knee flexion velocity and the muscle flexibility of the iliopsoas. For foot/shank injuries, only the hamstring:quadriceps strength ratios increased for the right side to a small effect size. Conclusions Injury grouping appears to increase effect size for certain risk factors. Athletes with a slower knee flexion velocity during stance phase were more likely to become injured (p-value <.03, r(pb) = .37). An increased cohort size to further sub-divide injuries into specific diagnoses is needed.
