- 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.

- The COVID-19 pandemic precipitated numerous changes in daily life, including the cancellation and restriction of sports globally. Because sports participation contributes positively to the development of student-athletes, restricting these activities may have led to long-term mental health changes in this population. Using a repeated cross-sectional study design, we measured rates of depression using the Patient Health Questionnaire-2 and anxiety using the Generalized Anxiety Disorder-2 scale in student-athletes attending elite sport high schools in Sweden during the second wave of the pandemic (February 2021; n = 7021) and after all restrictions were lifted (February 2022; n = 6228). Depression among student-athletes decreased from 19.8% in 2021 to 17.8% in 2022 (p = .008, V = .026), while anxiety screening did not change significantly (17.4% to 18.4%, p > .05). Comparisons between classes across years revealed older students exhibited decreases in depressive symptoms, while younger cohorts experienced increases in symptoms of anxiety from 2021 to 2022. Logistic regressions revealed that being female, reporting poorer mental health due to COVID-19, and excessive worry over one’s career in sports were significant predictors of both depression and anxiety screenings in 2022. Compared to times when sports participation was limited, the lifting of restrictions was associated with overall reduced levels of depression, but not anxiety.

- This review reexamines use of accelerometer and oxygen uptake data for assessment of activity intensity. Accelerometers capture mechanical work, while oxygen uptake captures the energy cost of this work. Frequency filtering needs to be considered when processing acceleration data. A too restrictive filter attenuates the acceleration signal for walking and, to a higher degree, for running. This measurement error affects shorter (children) more than taller (adults) individuals due to their higher movement frequency. Less restrictive filtering includes more movement related signals and provide measures that better capture mechanical work, but may include more noise. An optimal filter cut-point is determined where most relevant acceleration signals are included. Further, accelerometer placement affects what part of mechanical work being captured. While the waist placement captures total mechanical work and therefore contributes to measures of activity intensity equivalent by age and stature, the thigh and wrist placements capture more internal work and do not provide equivalent measures. Value calibration of accelerometer measures is usually performed using measured oxygen uptake with the metabolic equivalent of task (MET) as reference measure of activity intensity. However, the use of MET is not stringent and is not a measure of activity intensity equivalent by age and stature. A candidate measure is the mass-specific net oxygen uptake, VO2 net (VO2 tot - VO2 stand). To improve measurement of physical activity intensity using accelerometers, research developments are suggested concerning processing of accelerometer data, use of energy expenditure as reference for activity intensity, and calibration procedure with absolute versus relative intensity.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Previous population-based studies investigating the relationship between physical activity and the gut microbiota have relied on self-reported activity, prone to reporting bias. Here, we investigated the associations of accelerometer-based sedentary (SED), moderate-intensity (MPA), and vigorous-intensity (VPA) physical activity with the gut microbiota using cross-sectional data from the Swedish CArdioPulmonary bioImage Study.METHODS: In 8416 participants aged 50-65, time in SED, MPA, and VPA were estimated with hip-worn accelerometer. Gut microbiota was profiled using shotgun metagenomics of faecal samples. We applied multivariable regression models, adjusting for sociodemographic, lifestyle, and technical covariates, and accounted for multiple testing.FINDINGS: Overall, associations between time in SED and microbiota species abundance were in opposite direction to those for MPA or VPA. For example, MPA was associated with lower, while SED with higher abundance of Escherichia coli. MPA and VPA were associated with higher abundance of the butyrate-producers Faecalibacterium prausnitzii and Roseburia spp. We observed discrepancies between specific VPA and MPA associations, such as a positive association between MPA and Prevotella copri, while no association was detected for VPA. Additionally, SED, MPA and VPA were associated with the functional potential of the microbiome. For instance, MPA was associated with higher capacity for acetate synthesis and SED with lower carbohydrate degradation capacity.INTERPRETATION: Our findings suggest that sedentary and physical activity are associated with a similar set of gut microbiota species but in opposite directions. Furthermore, the intensity of physical activity may have specific effects on certain gut microbiota species.FUNDING: European Research Council, Swedish Heart-Lung Foundation, Swedish Research Council, Knut and Alice Wallenberg Foundation.

Tidskriftsartikel (refereegranskat)abstract
- It is common in elite sport to monitor athletes' training load, injuries and illnesses, but mental distress is rarely included. An improved understanding of the epidemiology of mental distress among elite Para athletes and how their coaches perceive such monitoring would allow us to better develop and implement preventive measures. The purpose of this study was therefore to (1) prospectively describe elite Para athletes' mental distress, before, during and after the Beijing Paralympic Games (Paralympics Games 22 = PG22); and to (2) gain a better understanding of if and potentially how awareness of athletes' mental distress changed, through weekly monitoring, and influenced how coachers perceive athletes' mental distress and if they accounted for this before, during and after PG22. A mixed-method study design was used, in which prospective mental distress (depression and anxiety) data were collected weekly from 13 [Swedish] elite Para athletes in preparation, during and after PG22. Data were screened and evaluated weekly by a physiotherapist and a sports psychologist, and coaches also received weekly reports. A focus-group interview with the coaches were conducted post Paralympics to address coaches' awareness about mental distress and athlete health monitoring in Parasport. For data analyses, descriptive statistics was used for the quantitative data and a content analysis was conducted for the qualitative data. The results reveled the following proportion of datapoints indicating symptoms of anxiety and depression: before PG22 (15.8 and 19.1%); during PG22 (47.6 and 38.2%); and after PG22 (0 and 11.8%). The qualitative results indicated that coaches perceived athlete health monitoring as helpful for increasing their awareness of mental distress, and as a useful tool to initiate support for their athletes as well as improving their coaching. In summary, this cohort of elite Para athletes reported a high proportion of mental distress during the Winter Paralympic Games in Beijing. The results also show that it is important and feasible to monitor Para athletes' mental distress to detect and manage early symptoms of mental distress.

Managing Intensity in Knowledge Work : Self-Leadership Practices among Danish Management Consultants
- 2021
-
Ingår i: Journal of Management and Organization. - : Cambridge University Press (CUP). - 1833-3672 .- 1839-3527. ; 27:2, s. 342-360

Tidskriftsartikel (refereegranskat)abstract
- This paper examines the sources of knowledge workers’ work intensity and the self-leading strategies they apply to deal with it. The paper is based on focus group interviews with management consultants in a Danish management consultancy firm. Work intensity was identified as resulting from a combination of: (1) a results-only focus, (2) vagueness, (3) boundaryless work, and (4) low control of the quantitative load. A framework for self-leading strategies is developed based on the dimensions of reactive/proactive and self-focused/externally-focused strategies in different combinations. The results indicate that while consultants expressed a belief in internal self-discipline strategies of a more reactive nature, in fact, external and proactive strategies were the most effective in practice. In conclusion, the paper contributes to an extension of self-leadership theory to better account for current research on self-control.

Navigating the Activity Based Working Environment – Relationships of Self-Leadership, Autonomy and Information Richness with Cognitive Stress and Performance
- 2019

Ingår i: Scandinavian Journal of Work and Organizational Psychology. - Stockholm : Stockholm University Press. - 2002-2867.

Tidskriftsartikel (refereegranskat)abstract
- In Activity Based Working Environment (ABWE) offices, employees are allowed increased autonomy and are expected to choose where, when, with whom, and to some degree with what, to work; in other words, employees are expected to self-lead to a higher degree and to coordinate and align with colleagues. Effects of these expectations on employees’ cognitive stress and performance are understudied. In the present study, Swedish ABWE workers (N = 416) are compared with workers in cell offices (N = 30) and landscape offices (N = 64), and relationships of self-leadership, information richness, and autonomy with cognitive stress and performance were examined using regression analysis. Results show no relationship between office type and outcomes. For cognitive stress, information richness had the largest negative relationship, followed by self-leadership: goal-setting and autonomy. For performance, self-leadership: goal-setting had the largest positive relationship, followed by information richness. This suggests that when organizational situations cannot be strongly structured – for example because the best work process is not known, or innovation or different collaboration constellations are needed – they need instead to be enriched so that employee orientation and coordination do not become too much of a burden on the individual employee, disrupting cognitive functioning and performance.

- In this study, a previously evaluated guided Internet-based cognitive behavior therapy for social anxiety disorder (SAD) was adapted for mobile phone administration (mCBT). The treatment was compared with a guided self-help treatment based on interpersonal psychotherapy (mIPT). The treatment platform could be accessed through smartphones, tablet computers, and standard computers. A total of 52 participants were diagnosed with SAD and randomized to either mCBT (n = 27) or mIPT (n = 25). Measures were collected at pre-treatment, during the treatment, post-treatment and 3-month follow-up. On the primary outcome measure, the Liebowitz Social Anxiety Scale - self-rated, both groups showed statistically significant improvements. However, mCBT performed significantly better than mIPT (between group Cohen's d = 0.64 in favor of mCBT). A larger proportion of the mCBT group was classified as responders at post-treatment (55.6% versus 8.0% in the mIPT group). We conclude that CBT for SAD can be delivered using modern information technology. IPT delivered as a guided self-help treatment may be less effective in this format. (c) 2014 Elsevier Ltd.

Anti-doping and legitimacy : an international survey of elite athletes’ perceptions
- 2016

Tidskriftsartikel (refereegranskat)abstract
- Anti-doping work is a comprehensive enterprise that entails control and governance of elite athletes’ everyday lives. However, in policy-making regarding doping and anti-doping in elite sports, the athletes’ perspective has not been considered adequately. Focusing on elite athletes’ perceptions of anti-doping as both principle and praxis, the study aimed to analyse how these perceptions can be understood from a legitimacy perspective. A survey study involving 261 elite athletes from 51 different countries and four international sports federations was conducted. The results showed that the athletes did not question the legitimacy of the rules, but had concerns about the legitimacy of the way the rules and principles are enforced in practice, specifically with regard to matters of privacy, lack of efficiency and equal conditions as well as athletes’ involvement in the anti-doping work. The article describes how athletes’ perceptions of the legitimacy of anti-doping work constitute the basis for their willingness to follow regulations as well as a precondition for the work’s functionality and stability. In light of this finding, the article calls for the empowerment of athletes in anti-doping work.
