3D digital modelling in visual arts education
- 2024
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- The following 3D Digital Modelling in Visual Arts Education forms part of the Tilde seriesand is based on collaboration in a project involving Aalborg University and College University Copenhagen (Denmark), the University of Gothenburg and Umeå University (Sweden).The project’s aim was to explore the learning potential held by 3D sculpting for art teachersby identifying new image-making processes in modelling and sculpting. Another aim wasto integrate the project’s outcome in didactics and teaching activities for teacher educatorsin visual arts connected to the subject area.The project was fnanced by EDDA Norden during 2021 and several seminars werearranged to present research in the subject area visual arts, 3D modelling, and use of technology. The results may be of particular interest to a wider audience in the research felds ofvisual arts education, multimodal learning designs, and teacher education. The publicationis based on presentations made at Aalborg University in Copenhagen during the autumn of2021 and at a symposium called 3D-sculpting: A Nordic Higher Education CollaborationProject at the NERA conference held in Oslo in the spring of 2023.

Samlingsverk (redaktörskap) (populärvet., debatt m.m.)abstract
- Statsvetenskapliga institutionen vid Umeå universitet etablerades samtidigt som Umeå universitet invigdes 1965. Denna bok berättar historien om institutionens första femtio år. Den ger inblickar i viktiga händelser, avgörande beslut, genomgående tendenser och tongivande förändringar. Det är en historia med både glädjeämnen och besvikelser, framgångar och motgångar.Att institutionen överlevt, expanderat och delvis kunnat förnya sig vittnar dock om att den i grunden utgör en livskraftig och dynamisk akademisk miljö med engagerade och kompetenta medarbetare.

99 years of the housing question in Sweden
- 2017
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- This book presents the history of modern architecture in Swedish housing. It is essential reading, especially at a time when a lack of accommodation is having such a brutal impact on Swedish society. However, this has not always been the case. Decisive public policies implemented during the 20th century led to an exemplary democratisation process of housing, unparalleled in terms of equality and inclusiveness. The first part of the book presents an overview of housing responses in Sweden. It dissects the housing question, describing it as a multidimensional phenomenon that cannot be addressed without considering social, political and economic circumstances. The second part compiles texts and materials from the exhibition Bo. Nu. Då: Bostadsfrågor och svar under 99 år (Housing. Now. Then: 99 Years of Housing Issues and Responses) held at ArkDes in 2016 and curated by Dan Hallemar. Based on the rich ArkDes collections, the book features examples of architectural solutions to the housing question from 1917 to the present. 99 Years of the Housing Question in Sweden brings together different perspectives, contributions, accounts and critiques from specialists and citizens alike, each illustrating in its own way how modern Swedish housing and society have developed and evolved hand in hand. The result is an important but relatively unknown discourse on the role of housing in the construction of the welfare state which offers vital lessons for today’s world.

A cultural history of color : Volume 6, In the modern age
- 2021
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- A Cultural History of Color in the Modern Age covers the period 1920 to the present, a time of extraordinary developments in colour science, philosophy, art, design and technologies. The expansion of products produced with synthetic dyes was accelerated by mass consumerism as artists, designers, architects, writers, theater and filmmakers made us a 'color conscious' society. This influenced what we wore, how we chose to furnish and decorate our homes, and how we responded to the vibrancy and chromatic eclecticism of contemporary visual cultures.The volume brings together research on how philosophers, scientists, linguists and artists debated color's polyvalence, its meaning to different cultures, and how it could be measured, manufactured, manipulated and enjoyed.Color shapes an individual's experience of the world and also how society gives particular spaces, objects, and moments meaning. The 6 volume set of the Cultural History of Color examines how color has been created, traded, used, and interpreted over the last 5000 years. The themes covered in each volume are color philosophy and science; color technology and trade; power and identity; religion and ritual; body and clothing; language and psychology; literature and the performing arts; art; architecture and interiors; and artefacts.

A decade of research on school principals : cases from 24 countries
- 2016. - 1
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- This book provides a unique map of the focus and directions of contemporary research on school leadership since 2000 in 24 countries. Each of these directions has its own particular cultural, educational and policy history. Taken together, the various chapters in the volume provide a rich and varied mosaic of what is currently known and what is yet to be discovered about the roles and practices of principals, and their contributions to the improvement of teaching and the learning and achievement of students. The particular foci and methodological emphases of the research reported illustrate the different phases in the development of educational policies and provision in each country. This collection is an important addition to existing international research that has shown beyond any reasonable doubt that the influence of school principals is second only to that of teachers in their capacity to impact students’ progress and achievement and to promote equity and social justice.

Parents’ experiences of transitioning to home with a very-low-birthweight infant : a meta-ethnography
- 2023
-
Ingår i: Journal of Neonatal Nursing. - : Elsevier. - 1355-1841 .- 1878-089X. ; 29:3, s. 444-452
-
Forskningsöversikt (refereegranskat)abstract
- Medical-technological advances and neurodevelopmental care have improved the survival of extremely- and very-low-birthweight infants born before 32 weeks' gestation. After months in neonatal care, the infants are discharged, and parents exited but full of anxiety. This review is designed as a meta-ethnography, addressing parents' discharge experiences to comprehend the synthesised research, which includes 12 eligible studies. From the analysis, we constructed three themes: ‘approaching discharge with both uncertainty and confidence’; ‘discharge as a longed-for though disordering turning point’; and ‘facing joys, worries and multiple challenges when at home’. The overarching interpretation was ‘discharge as double-edged sword’. We conclude that bringing home very-low-birthweight infants is a joyful event, yet parents also experience discharge as never-endingly worrying, as a time filled with challenges to which parents must adapt and as necessitating continuous support from knowledgeable providers.

- We give an upper bound on the number of perfect matchings in simple graphs with a given number of vertices and edges. We apply this result to give an upper bound on the number of 2-factors in a directed complete bipartite balanced graph on 2n vertices. The upper bound is sharp for even n. For odd n we state a conjecture on a sharp upper bound.

Governance patterns and performance of regional strategies in peri-urban areas : comparative analysis of seven cases in Europe and Chine
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report examines how different regional and local governance patterns and specific spatial planning strategies impact on peri-urban land use in Rural Urban regions. It draws from seven regional case studies, presenting a diverse mix of strategies ranging from protecting biodiversity and agricultural land, creating recreation and tourism opportunities to reducing pressure from building and infrastructure development. To study the means of influence or power an analytical framework of ‘policy arrangement’ was employed (Tatenhove et al, 2000): specifying rules of the game, resources, coalitions and discourses. Both government and nongovernment actors such as environmental groups or developers can form coalitions, adopt rules, employ resources and develop discourses to influence policies and developments in urban regions. The analytical and assessment frameworks defined by regional researchers and practitioners helped to organize the case study data and to evaluate both processes and outcomes of governance in peri-urban areas. The outcomes are represented in a summarized way for each strategy and region.The report provides examples of unsustainable developments in peri-urban regions and how certain strategies helped to counteract these, and emphasizes the importance of recognizing peri-urban areas as a policy field in its own right.A sustainable spread of land use over the Rural Urban region requires regional authorities whose jurisdiction covers the Rural Urban region and who have the appropriate mix of policy means of influence and relative power over lower level authorities. Under the current predominant discourse of ‘sustainable’ development largely being equal to economic development, the outcome of sustainability concerns depends on urban areas taking financial responsibility for the inclusion of common good interests such as ecosystem services, cultural heritage and social and environmental justice into the periurban areas. Recommendations for policy makers at different levels conclude the report.

As explained in Chap. 1, there are a range of particular policy challenges in the urban fringe. The policies of several adjacent municipalities or local authorities may be combined and managed by an indirectly elected regional authority, while different national and EU-level sectoral and regional policies frequently interfere with each other in such areas. Problems of implementation deficits with sector-based strategies are commonplace following institutional fragmentation, calling for increased co-ordination and better integration mechanisms (Tatenhove et al. 2000).

The Sami Representations Reflecting the Multi-Ethnic North of the Saga Literature
- 2017
-
Ingår i: Journal of Northern Studies. - Umeå : Umeå University. - 1654-5915 .- 2004-4658. ; 11:2, s. 7-30
-
Tidskriftsartikel (refereegranskat)abstract
- This article focuses on contextualizing the Sami (finnar) representations in Old Norse saga literature. The purpose is to show that the Sami representations reflect multi-layered Old Norse textual and oral traditions, and complex interaction between the Sami and the Norwegians in the Middle Ages. The stereotypes of the Sami tell us more about the society that created them than about real, historical events. We can be sure that behind them lie very mundane phenomena such as trade and marriages.The ultimate goal of the article is therefore to reveal the multi-ethnic North that provided the background for the saga sources, a North whose history is not as homogeneous as sources suggest and quite unlike the modified version which found its way into the histories of nation states. The literary conventions of sagas are not just imaginary tales—their use in various contexts can reveal something essential in otherwise schematic images or configurations. Even researchers of the sagas have certain personal conceptions of what the “real” lives of the Sami were like at the time, and how the sagas depict this. In fact, they participate in a continuum of saga literature that generates representations of the Sami in history.

Scholars' open debate paper on the World Health Organization ICD-11 Gaming Disorder proposal

-

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Concerns about problematic gaming behaviors deserve our full attention. However, we claim that it is far from clear that these problems can or should be attributed to a new disorder. The empirical basis for a Gaming Disorder proposal, such as in the new ICD-11, suffers from fundamental issues. Our main concerns are the low quality of the research base, the fact that the current operationalization leans too heavily on substance use and gambling criteria, and the lack of consensus on symptomatology and assessment of problematic gaming. The act of formalizing this disorder, even as a proposal, has negative medical, scientific, public-health, societal, and human rights fallout that should be considered. Of particular concern are moral panics around the harm of video gaming. They might result in premature application of diagnosis in the medical community and the treatment of abundant false-positive cases, especially for children and adolescents. Second, research will be locked into a confirmatory approach, rather than an exploration of the boundaries of normal versus pathological. Third, the healthy majority of gamers will be affected negatively. We expect that the premature inclusion of Gaming Disorder as a diagnosis in ICD-11 will cause significant stigma to the millions of children who play video games as a part of a normal, healthy life. At this point, suggesting formal diagnoses and categories is premature: the ICD-11 proposal for Gaming Disorder should be removed to avoid a waste of public health resources as well as to avoid causing harm to healthy video gamers around the world.

Tidskriftsartikel (refereegranskat)abstract
- Objective:The primary aim was to assess, the association of the quantity and quality of dietary fat intake from 6 to 12 months of age and serum lipids at 12 months.Subjects/Methods:Three hundred healthy term Swedish infants were recruited in a longitudinal prospective study at the age of 6 months; 276 remained in the study at 12 months. Food records and anthropometric data were collected monthly from 6 to 12 months; serum lipids were analysed at 6 and 12 months.Results:Swedish infants had a total fat intake within the Nordic recommendations, but intake of polyunsaturated fatty acids (PUFA) was low (5.6 percent of total energy (E%)) and intake of saturated fatty acids (SAFA) was high (15.1 E%). Higher PUFA intake was associated with lower total serum cholesterol (TC, B=-0.13, P=0.003), lower low-density-lipoprotein cholesterol (LDL-C, B=-0.12, P=0.004) and apolipoprotein B (B=-0.03) (P=0.034) in girls but not in boys. When data from the present study were compared to data from similar studies in Finland and Iceland, it appears that the quality of the dietary fat has greater impact on serum lipid levels than the quantity of fat in the diet.Conclusions:Higher PUFA and lower SAFA intakes may reduce TC and LDL-C early in life, particularly in girls. Further, with respect to lowering serum lipid concentrations in early childhood it seems appropriate to set focus on fat quality rather than the quantity.Sponsorships:Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning (Formas), Swedish Research Council, Medicine, Stiftelsen Oskar Foundation, Sven Jerring Foundation, Samariten Foundation, Stiftelsen Goljes minne and Semper AB.European Journal of Clinical Nutrition advance online publication, 20 June 2007; doi:10.1038/sj.ejcn.1602824.

The future of greying Europe : Conclusion
- 2013
-
Ingår i: Old age in Europe. - Dordrecht : Springer Netherlands. - 9789400761346 - 9789400761339 ; , s. 131-136
-
Bokkapitel (refereegranskat)abstract
- Although Europe’s population is greying, the future of Europe does not look grey. What can be learned from this book is that old age is not necessarily characterized by frailty and decline, but instead can be a time of self-fulfillment, activity, and social participation. Moreover, we now know that population ageing does not need to threaten extant social and welfare state-related institutions, but instead opens up potentials for restructuring and reinvention. Life expectancy is longer than ever before and living conditions that enhance healthy ageing have very much improved. New technologies and Information and Communication Technologies may assist older people to stay in their homes longer. The growing possibilities to reach a good old age may have given rise to what is sometimes called ‘a silver economy’: an economy with all kinds of new products and services, particularly aimed at the growing share of healthy and wealthy senior citizens. The greying of Europe might, thus, ultimately lead us into a bright and colourful future.

- This article examines and compares principal training programs in Sweden and Norway, the two Nordic countries with national leadership programs for already active school leaders. To investigate the knowledge base and design of the programs we draw on two research-derived tools about successful professional learning programs for school leaders. Based on the examinations, we suggest that the programs reflect international research both in terms of content and process factors. In addition, we identify topics and issues, such as balancing democratic participation with managerial decision-making, which can be characterized as making up a Nordic profile.

- Background: The main aim was to examine whether patients with persistent upper quadrant pain have higher end-point variability in goal directed pointing movements than pain-free controls when the pointing task is performed in total darkness and under full vision. An additional aim was to study associations between the magnitude of end-point variability and a clinical movement control test battery and self-rated functioning among patients.Methods: Seventeen patients and 17 age- and gender-matched pain-free controls performed a pointing task that evaluated end-point variability of repetitive shoulder movements in horizontal adduction and abduction with full vision, and abduction with no visual information, completed a movement control test battery of neck and shoulder control tests and answered questionnaires.Results: Patients had higher end point variability for horizontal abduction when performed with no visual information. For horizontal adduction the variability was higher, but only when it was controlled for movement time. No significant correlations were found between end-point variability and self-rated functioning, nor between end-point variability and neuromuscular control of the glenohumeral joint.Conclusions: This study provides preliminary evidence that patients with persistent neck/shoulder pain can partly compensate proprioceptive deficits in goal-directed arm movement when visual feedback is present.

Tidskriftsartikel (refereegranskat)abstract
- Study design: Inter-rater reliability study. Background: Physiotherapists (PTs) use clinical tests including movement tests to identify faulty movement patterns. Aims: To investigate the inter-rater-reliability of active movement tests in the cervical spine, shoulder joint and scapulo-thoracic joint, and to describe the reasons for judgment of a positive test. Methodology: Four PTs, two experienced and two recently educated (novice), rated performance of five movement tests for 36 participants. Twenty-one of the participants were patients under treatment because of neck and/or shoulder problems, while 15 participants declared no problem from this region of the body. All tests were video recorded and the ratings were done by observing the video recordings. First, the PTs judged the tests as negative (the movement being ideally performed) or positive (the movement not being ideally performed). Then, the PTs described why the movements that they judged positive were not being ideally performed, using a predefined protocol, which represented different movement quality aspects. The inter-rater reliability was calculated for each test using Kappa statistics between the two experienced and the two novice PTs, respectively, and between each of the experienced and each of the novice PTs. Major findings: The experienced PTs had a higher inter-rater reliability than the novice PTs. The reasons for considering a movement test being positive differed highly between the (novice) PTs. Principal conclusion: This study supports previous studies concluding that the observation of active movement tests is reliable when assessed by experienced PTs. Novice PTs might benefit from further supervision.

- Study Design Randomized controlled trial. Background Low back pain is a common disorder. Patients with low back pain frequently have aberrant and pain-provocative movement patterns that often are addressed with motor control exercises. Objective To compare the effects of low-load motor control (LMC) exercise and those of a high-load lifting (HLL) exercise. Methods Seventy participants with recurrent low back pain, who were diagnosed with nociceptive mechanical pain as their dominating pain pattern, were randomized to either LMC or HLL exercise treatments. Participants were offered 12 treatment sessions over an 8-week period. All participants were also provided with education regarding pain mechanisms. Methods Participants were assessed prior to and following treatment. The primary outcome measures were activity (the Patient-Specific Functional Scale) and average pain intensity over the last 7 days (visual analog scale). The secondary outcome measure was a physical performance test battery that included 1 strength, 3 endurance, and 7 movement control tests for the lumbopelvic region. Results Both interventions resulted in significant within-group improvements in pain intensity, strength, and endurance. The LMC group showed significantly greater improvement on the Patient-Specific Functional Scale (4.2 points) compared with the HLL group (2.5 points) (P<.001). There were no significant between-group differences in pain intensity (P = .505), strength, and 1 of the 3 endurance tests. However, the LMC group showed an increase (from 2.9 to 5.9) on the movement control test subscale, whereas the HLL group showed no change (from 3.9 to 3.1) (P<.001). Conclusion An LMC intervention may result in superior outcomes in activity, movement control, and muscle endurance compared to an HLL intervention, but not in pain intensity, strength, or endurance.

A descriptive analysis of functional impairments and patho-anatomical findings in eight powerlifters
- 2020
-
Ingår i: Journal of Sports Medicine and Physical Fitness. - : Edizioni Minerva Medica. - 0022-4707 .- 1827-1928. ; 60:4, s. 582-593
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Low back pain (LBP) is a common pain problem in powerlifters. There is a lack of evidence to guide powerlifters and health-care professionals in understanding the role of powerlifting in the development of LBP and treatment of injuries in powerlifters. This study aimed to describe functional impairments and patho-anatomical findings in eight powerlifters with and without LBP. METHODS: First, four powerlifters with LBP were recruited. Each powerlifter was then matched with a pain-free lifter (Control) by age, Body Mass Index and competition weight class. They all performed physical performance tests and were examined with magnetic resonance imaging. Four weeks prior to the examination the powerlifters also recorded training load. Powerlifters with LBP were also examined by a physiotherapist in order to define their pain and impairments. RESULTS: The four male powerlifters with LBP had a nociceptive pain associated with non-ideal squatting technique, higher flexibility in their lumbar spine than in their hips and patho-anatomical findings such as degenerated discs (four), spondylolysis (one) and spinal stenosis (one). However, the controls also showed similar functional impairments and patho-anatomical findings. CONCLUSIONS: Powerlifters with and without LBP show similar functional impairments and patho-anatomical findings. However, powerlifters' LBP seems associated with pain during movement and loading of the lumbar spine. The association and causation between specific functional impairments, patho-anatomical findings and LBP in powerlifters has to be further investigated in studies including more participants.

Ambulance Work : Relationships between occupational demands, individual characteristics and health-related outcomes
- 2005
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Although musculoskeletal disorders (MSDs) and other health complaints are an occupational problem for ambulance personnel, there is a lack of knowledge regarding work-related factors associated with MSDs and other health complaints. The overall aim of this thesis was to investigate the relationships between occupational demands, individual characteristics and health-related outcomes among ambulance personnel. A random sample of 234 female and 953 male ambulance personnel participated in a national questionnaire survey on work-related factors, and musculoskeletal and other health complaints. Physical demands was associated with activity limitation due to neck-shoulder and low-back complaints among the female personnel. Among the male personnel, physical demands was associated with low-back complaints and activity limitation due to low-back complaints. Psychological demands was significantly associated with neck-shoulder complaints, sleeping problems, headache and stomach symptoms among both female and male ambulance personnel. Worry about work conditions was associated with musculoskeletal disorders and sleeping problems, headache and stomach symptoms. A local sample of 26 ambulance personnel was followed during a 24-hour work shift and for the next two work-free days. Subjective stress- and energy levels, and cortisol levels were measured at regular intervals, and heart rate was registered continuously by electrocardiogram (ECG). Autonomic reactivity to standardized tests before (pre-work) and at the end of the work shift (post-work) was also investigated. For the whole group, baseline values of heart rate were higher pre-work than post-work, but autonomic reactivity did not differ. Increased reactivity to the mental test, modest deviation in heart rate variability (HRV) pattern during the late night hours at work and higher morning cortisol values during work than during leisure time were observed in personnel with many health complaints, but not among their co-workers without or with few complaints. Ambulance personnel with many health complaints also reported higher psychological demands and tended to be more worried about work conditions. Heart rate (HR), lactate level (LL) and perceived exertion (RPE) were investigated in 17 female and 48 male ambulance personnel during a simulated standardized work task “carry a loaded stretcher”. The ambulance personnel had to carry the loaded stretcher (920 N) up and down three flights of stairs twice. The high physiological strain (HR, LL, RPE) for the male, and near or at maximal strain for the female ambulance personnel, implied the importance to identify what kind of physical capacity is most important for ambulance personnel. Therefore, the explained variance of developed fatigue by tests of cardiorespiratory capacity, muscular strength and endurance, and coordination was investigated. The results showed that VO2max and isometric back endurance were important predictors for development of fatigue when carrying a loaded stretcher. The influence of body size on the relationships between maximal strength and functional performance was investigated in a methodological study. The results confirm that the assessment of physical performance could be confounded by the body weight. Therefore, the models for explaining development of fatigue when carrying the loaded stretcher were adjusted for height and weight. Including height in the models significantly increased the explained variance of accumulated lactate among female, but not among male personnel. Lactate levels were higher among short compared to tall female personnel. Weight had no effect on any of the models. In conclusion, the national survey showed that self-reported physical demands was a risk factor of having MSDs, and that self-reported psychological demands and worry about work were important risk factors of having MSDs and other health complaints. Stress monitoring of ambulance personnel during work and leisure time showed that physiological and subjective stress markers did not show any differences between the 24-hour ambulance work shift and leisure time afterwards. However, ambulance personnel with many health complaints had certain physiological changes during the work shift in comparison with the next two work-free days. The physiological and subjective responses during carrying a loaded stretcher, especially among the female ambulance personnel, showed that female and male ambulance personnel could be exposed to internal exposures at different levels when performing the same work task. A better understanding of the relationships between occupational demands and health-related outcomes require further studies on age- and gender matched groups in long-term perspective studies.

- The aims of the study were (1) to investigate the effects of participation in low impact body conditioning classes on physical fitness in sedentary women at different ages and (2) to examine the correspondence between physical self-concept and participation in, and fitness change after, the participation. Ninety-two sedentary women (mean age 44.2 years) participated in 11-weeks of bi-weekly classes that included cardiovascular, strength, core, endurance and mobility exercises, all performed in synchrony with music. Cardiorespiratory fitness, maximal lifting strength, mobility and balance tests were performed pre- and post the exercise period and the short-form Physical Self-Description Questionnaire (PSDQ-S) was completed. Zero-order Spearman correlation analyses showed that women who rated the PSDQ-S dimension Sport competence higher participated in a larger number of sessions (rs=0.24, p=0.040). At post-tests, all participants had increased their balance, the participants aged 20-34 years had increased their lifting strength, and the participants aged 35-65 years had increased their cardiorespiratory fitness and mobility. Most PSDQ-S dimensions did not affect performance change, but the perception of being physically active was related to increased cardiovascular fitness. We conclude that women with a sedentary lifestyle who wish to increase their physical capacity benefit from music exercise and that inquiries about perceived sport competence and physical activity can improve recommendations made by strength and conditioning professionals.

- Background Olympic weightlifting and powerlifting are two sports that expose the body to great forces. Injury characteristics have not been systematically reviewed for these two growing sports.Objective The purpose of this study was to systematically review the literature regarding various definitions of injuries used, injury localisation, the prevalence and incidence of injuries and the associated risk factors for injuries in weightlifting and powerlifting.Design Systematic review.Data sources Five databases, PubMed, MEDLINE, SPORTDiscus, Scopus and Web of Science, were searched between 9 March and 6 April 2015.Eligibility criteria for selecting studies Studies assessing injury incidence and prevalence in Olympic weightlifting and powerlifting were included. The Quality assessment tool for observational cohort and cross-sectional studies was used to assess methodological quality.Results 9 studies were included in the review. Injury was defined fairly consistently across studies. Most studies were of low methodological quality. The spine, shoulder and the knee were the most common injury localisations in both sports. The injury incidence in weightlifting was 2.4–3.3 injuries/1000 hours of training and 1.0–4.4 injuries/1000 hours of training in powerlifting. Only one retrospective study had analysed possible risk factors.Summary/conclusions The risk of injury in both sports were similar to other non-contact sports also requiring strength/power, but low compared to contact sports. The severity of injuries differed in the included studies. Since little has been studied regarding possible risk factors to injuries, further research is therefore warranted to explain why athletes get injured and how to prevent injuries.Trial registration number PROSPERO CRD42015014805.

- The aim of the study was to test the hypothesis that the body size plays an important role in assessment of muscle ability to exert force by standard functional performance tests. Twenty-one male students were tested on maximal isometric lift, one leg rising, vertical jump, and box lift tests, and the maximal isokinetic strength of hip and knee extensors was also recorded. When indices of the 4 functional performance tests were related to the strength of each of the 2 leg extensor muscle groups, only maximal isometric lift demonstrated positive correlation with knee extensors strength. When muscle strength was corrected for body mass, however, the aforementioned relationship became insignificant, but the 1 leg rising performance demonstrated a positive relationship with knee extensor strength. In addition, maximal isometric lift and 1 leg rising test performance provided positive and negative correlation, respectively, with body mass. The obtained findings were in line with the effects of scale applied on the tested performance. We generally conclude that the assessment of muscle capability to exert force based on some standard functional performance tests could be confounded by the body size effect.

- STUDY DESIGN: Longitudinal design. A cohort followed in 3 waves of data collection.OBJECTIVE: The aim of the study was to describe the relationships between the performance of 2 tests of spinal control at the age of 52 years and low back pain, physical activity level, and fitness earlier in life, as well as to describe the cross-sectional relationships between these measures.SUMMARY OF BACKGROUND DATA: Altered spinal control has been linked to pain; however, other stimuli may also lead to inability to control the movements of the spine.METHODS: Participants answered questions about physical activity and low back pain, and performed physical fitness tests at the age of 16, 34, and 52 years. The fitness test battery included tests of endurance in the back and abdominal muscles, a submaximal bicycle ergometer test to estimate maximal oxygen uptake, and measurements of hip flexion, thoracic spine flexibility, and anthropometrics. Two tests were aggregated to a physical fitness index. At the age of 52, also 2 tests of spinal control, the standing Waiter's bow (WB) and the supine double leg lower (LL) were performed.RESULTS: Logistic regression analyses showed that higher back muscle endurance at the age of 34 years could positively predict WB performance at 52 years and higher physical fitness at the age of 34 could positively predict LL performance at 52 years. Regarding cross-sectional relationships, an inability to perform the WB correctly was associated with lower physical fitness, flexibility and physical activity, and larger waist circumference. An inability to correctly perform the LL was associated with lower physical fitness. One-year prevalence of pain was not significantly associated with WB or LL test performance.CONCLUSION: An active life resulting in higher physical fitness is related to better spinal control in middle-aged men and women. This further strengthens the importance of physical activity throughout the life span.LEVEL OF EVIDENCE: 3.
