- Using a three-wave prospective cross-lagged panel design, the study examined six-month stability of burnout, self-compassion and social support among sports coaches in terms of measurement invariance, mean-level change, rank-order stability, and structural stability. The participating coaches (N = 422; Mage = 44.48, SD = 11.03) completed an online questionnaire measuring self-compassion, social support, coach burnout and demographics at baseline and two follow-ups at three months and six months. The various forms of stability were assessed using structural equation modeling. There was no significant mean-level change in burnout, self-compassion, or social support, and all three constructs exhibited measurement invariance. Rank-order stability remained relatively high, ranging from 0.78 to 0.94 across the three time points. For all three constructs, covariances between latent factors were invariant over time, indicating high structural stability. While self-compassion and social support were positively related, both were negatively related to coach burnout. These results confirm the importance of preventing and addressing symptoms of burnout, low self-compassion and poor social support in sports settings.

- Weak electromagnetic fields (WEF) alter Ca2+ handling in skeletal muscle myotubes. Owing to the involvement of Ca2+ in muscle development, we investigated whether WEF affects fusion of myoblasts in culture. Rat primary myoblast cultures were exposed to WEF (1.75 µT, 16 Hz) for up to six days. Under control conditions, cell fusion and creatine kinase (CK) activity increased in parallel and peaked at 4-6 days. WEF enhanced the extent of fusion after one and two days (by ~40%) vs. control, but not thereafter. Exposure to WEF also enhanced CK activity after two days (almost four-fold), but not afterwards. Incorporation of 3H-thymidine into DNA was enhanced by one-day exposure to WEF (~40%), indicating increased cell replication. Using the potentiometric fluorescent dye di-8-ANEPPS, we found that exposure of cells to 150 mM KCl resulted in depolarization of the cell membrane. However, prior exposure of cells to WEF for one day followed by addition of KCl resulted in hyperpolarization of the cell membrane. Acute exposure of cells to WEF also resulted in hyperpolarization of the cell membrane. Twenty-four hour incubation of myoblasts with gambogic acid, an inhibitor of the inward rectifying K+ channel 2.1 (Kir2.1), did not affect cell fusion, WEF-mediated acceleration of fusion or hyperpolarization. These data demonstrate that WEF accelerates fusion of myoblasts, resulting in myotube formation. The WEF effect is associated with hyperpolarization but WEF does not appear to mediate its effects on fusion by activating Kir2.1 channels.

Alcohol Consumption Over the Retirement Transition in Sweden : Different Trajectories Based on Education
- 2022
-
Ingår i: Work, Aging and Retirement. - : Oxford University Press. - 2054-4642 .- 2054-4650. ; 8:1, s. 74-81

Tidskriftsartikel (refereegranskat)abstract
- Retirement is a major life transition that involves changes to everyday routines, roles, and habits. Previous studies suggest that retirement may influence drinking habits. Many natural inhibitors of alcohol consumption disappear with the removal of work constraints. The potential impact depends on both individual and contextual factors. Women in the cohorts undergoing retirement now have been more active on the labor market, including the occupation of higher status jobs, which indicates more financial resources as well as a larger role loss after retirement. Also, the current cohorts who retire have had more liberal drinking habits throughout their lives compared to previous cohorts. We therefore examined changes in alcohol consumption surrounding retirement in different education groups among women and men undergoing retirement using annual data from the Health, Aging and Retirement Transitions in Sweden (HEARTS) study, a longitudinal national study of 60- to 66-year-olds (n = 5,913), from 2015 to 2018. Latent growth curve models were used to estimate trajectories of alcohol consumption. Results showed that those who retired during the follow-up increased their usual weekly alcohol consumption while those who worked or were retired throughout the period had stable drinking habits. Those who were retired reported the highest alcohol consumption. The increase surrounding retirement was driven by people with higher education. Women with tertiary education and men with intermediate or tertiary education increased their weekly alcohol intake after retirement, while those with low education had unchanged drinking habits. Mechanisms and motivations that may fuel increased alcohol intake among people with higher education should be further investigated.

Tidskriftsartikel (refereegranskat)abstract
- Although it is advocated that end-users are engaged in developing evidence-based injury prevention training to enhance the implementation, this rarely happens. The € Implementing injury Prevention training ROutines in TEams and Clubs in youth Team handball (I-PROTECT)' uses an ecological participatory design incorporating the perspectives of multiple stakeholders throughout the project. Within the I-PROTECT project, the current study aimed to describe the development of holistic injury prevention training specifically for youth handball players through using knowledge from both end-users (coaches and players) and researchers/handball experts. Employing action evaluation within participatory action research, the cyclical development process included three phases: research team preparation, handball expert-based preparation and end-user evaluation to develop injury prevention training incorporating both physical and psychological perspectives. To grow the knowledge of the interdisciplinary research team, rethinking was conducted within and between phases based on participants' contributions. Researchers and end-users cocreated examples of handball-specific exercises, including injury prevention physical principles (movement technique for upper and lower extremities, respectively, and muscle strength) combined with psychological aspects (increase end-user motivation, task focus and body awareness) to integrate into warm-up and skills training within handball practice. A cyclical development process that engaged researchers/handball experts and end-users to cocreate evidence-based, theory-informed and context-specific injury prevention training specifically for youth handball players generated a first pilot version of exercises including physical principles combined with psychological aspects to be integrated within handball practice. © 2022 BMJ Publishing Group.

Children's Rights to and in Sport : A Comparative Analysis of Organizational Policies in the Scandinavian Countries
- 2024
-
Ingår i: Social Sciences. - : MDPI. - 2076-0760. ; 13:4
-
Tidskriftsartikel (refereegranskat)abstract
- It has long been stated that children have the rights to protection from, e.g., abuse and to the provision of age-appropriate leisure, play, and recreational activities along with participation in all matters that concerns them. Yet, the full range of children's rights to and in sport has not yet been explored in detail. To do so, it is relevant to turn to the Scandinavian countries, which are praised for promoting children's rights and well-being, with organized sport forming part of the daily lives of many children and youths. In this paper, we examine the organizational policies in Scandinavian sport in order to develop foundational knowledge about how the range of children's rights to and in sport may be supported. Comparing key policy documents of the major sports confederations in Denmark, Norway, and Sweden, these analyses identify great variety in the following: 1. when and how children's rights to and in sport have been made explicit in the three countries; 2. whether the emphasis is on protection and/or provision of sport to children and youths or their participation in shaping sporting activities; 3. the degree to and ways in which such rights are regulated. In sum, our findings reflect a disparity between organizational policies in the three countries, with a more liberal and individualistic approach to public policy in the Danish context, providing some explanation of the only recent development in and scattered enaction of regulations to support children's rights to and in sports. Furthermore, we identify that political attention has mainly been drawn to the protection and provision of sports to children and youths, while their participation in shaping sport is a shared challenge for sport confederations in the Scandinavian countries and beyond.

Practising movement at home : An idea for meaningful remote teaching in physical education
- 2021
-

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Since March 2020, most physical education (PE) teachers in Scandinavia have faced the challenges of remote teaching. Homeschooling has perhaps been particularly challenging for PE teachers compared to other teachers, given the essential role of bodily contact, interaction, social negotiations, game playing and shared expressions in PE (Varea and González-Calvo, 2020).Having worked with covid conditions for a year now, we trust that teachers have worked out various solutions that, we hope, are relevant and meaningful for the students. At the same time, both from our personal experiences and early research findings (Mercier et al. 2021), it appears that PE teachers have largely provided students with physical activity and fitness training during the pandemic.In this short text, we want to share an idea for a concrete alternative to fitness exercises, which, although important, is only one part of the PE curriculum. It springs from a pedagogical model we outlined in a double article from 2018, which focuses on practising. Practising, which in German is üben and in the Scandinavian languages øve/öva, is, briefly put, a form of activity in which you seek to improve some part of yourself through repeated efforts.Recently, one of our colleagues, Dillon Landi, made us aware that this practising model is particularly relevant for teaching during the pandemic. While we did not have remote teaching in mind when we outlined the model, we realise now that it could be a relevant way of coping with the current situation. It can, we believe, guide how teachers can facilitate movement activities for students at home that are both meaningful and educationally relevant.In the following, we will describe what remote teaching with a focus on practising might look like. We hope it can inspire teaching methods that add to the list of pedagogical options available for teachers during the pandemic.

Breathing resistance in metabolic systems : Its effects on pulmonary ventilation and oxygen uptake in elite athletes with high aerobic power
- 2020

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to investigate the effects on pulmonary ventilation and oxygen uptake ( (V) over dot athletes with a very high maximal oxygen uptake (V) over dotO(2)max) and corresponding high ventilation capacity when using a modern metabolic system with relatively high resistance to breathing (HIGH(RES)), compared to a traditional system with low resistance to breathing (LOWRES). Four rowers and three cross-country skiers (without asthma), competing at a high international level, performed in experimental conditions with LOWRE (S)and HIGH(RES) using a rowing ergometer and roller skis on a treadmill. The results showed that (V) over dotO(2), blood lactate, heart rate and respiratory exchange ratio were not different between the LOWRES and HIGH(RES) test conditions during both submaximal and maximal exercise. Also, the athlete's time to exhaustion (treadmill) and mean power (rowing ergometer) from maximal tests were no different between the two conditions. However, ventilation and expiratory O-2 and CO2 concentrations were different for both submaximal and maximal exercise. Thus, the authors have concluded that the differences in resistance to breathing of metabolic systems influence elite endurance athletes (V) over dot(E)at low to very high workloads, thus affecting the expired gas fractions, but not the submaximal (V) over dotO(2), (V) over dotO(2)maxand performance in a laboratory setting at sea level.

Guarding the boundaries of belonging: the Church of Sweden, Gypsy mission and social care in the 1910s–40s

Tidskriftsartikel (refereegranskat)abstract
- Historically, social welfare providers have defined social and ethnic minorities such as ‘vagrants’ and Romani people as non-deserving and thus excluded them from their work. Gradually during the nineteenth century, however, Christian actors and organizations across Europe were among the first to recognize Romani groups as legitimate targets of relief. The operations required boundary changes where previously undeserving categories were transferred to deserving, thus becoming legitimate targets of relief. The article discusses the Church of Sweden’s social care for minorities, with a special focus on Romani groups from the 1910s to the 1940s. At that point, Protestant social work was permeated by conservative paternalism and focused on changing the individual through interventions defined as help-to-self-help, rather than challenging the unjust social structures in Swedish society. However, welfare measures were enacted differently depending on the majority/minority position of the individual; the recognition or rejection of minority rights affected the distribution and content of Lutheran social welfare. Examining church-led or church-endorsed activities, the contribution sheds light on the differentiation of social and ethnic subgroups and brings nuance to a field that has overlooked the Swedish state church as a welfare provider in the twentieth century. The instances of intersection between and sometimes confusion of social and ethnic boundaries serve as examples of the historicity of such boundaries and churchmen’s contribution to establishing these.

‘Rise up and walk!’ The Church of Sweden and the ‘problem of vagrancy’ in the early twentieth century
- 2022
-
Ingår i: Scandinavian Journal of History. - : Informa UK Limited. - 0346-8755 .- 1502-7716. ; 47, s. 156-177
-
Tidskriftsartikel (refereegranskat)abstract
- The article examines how people within the Church of Sweden’s leadership tried to solve ‘the problem of vagrancy’ in Sweden in the early twentieth century. In focus are the priest John Melander and the deacon Josef Flinth, who advocated and realized various activities for categories of poor and mobile men in the population. These interventions, defined as help-to-self-help, differentiated between the ‘worthy’ and the ‘unworthy’ needy. In publications and lectures, Melander and Flinth presented arguments to transfer ‘unworthy’ categories to the ‘worthy’, thereby expanding the community of value. This expansion was conditioned, however, by boundaries drawn regarding ideas on belonging and ethnicity. Working in the borderlands of the community as part of a Christian calling, Melander and Flinth contributed to the expansion of social work in the early twentieth century.
