    •  The use of educational computer games in physical education (PE) has become more popular in recent years and has attracted research interest. The aim of the article is to investigate how physical activities and images of the human body are offered by the game. The results show how the “teacher” constituted in the games is one who instructs and encourages the players to exercise and think about their bodies, but not a “teacher” who can help students to investigate, argue, or discuss images of health and the human body. We argue that the use of a wide range and variety of ways of teaching would make the teaching richer and offer a deeper understanding about the body and health.

    • In society, video- and computer games are often pointed out as risk factors in relation to physical inactivity, sedentary behaviour as well as increasing levels of obesity. At the same time, computers are an important source of knowledge where IT-competence and IT-experience provide pronounced advantages in society. In the middle of this paradox a new type of videogames is introduced, where body movement and physical activity constitute the central element. These games, so called exergames or active video games, are games where physical movement is involved in the game through the use of for example balance-boards, step-up boards and dance-pads. Exergames are now more and more put forward in several countries as interesting tools to use in physical education in order to stimulate young people to be physically active.In a recent review and synthesis of research on video games and health, Papastergiou (2009) strongly argues that videogames can offer ”potential benefits as educational tools for Health Education and Physical Education, and that those games may improve young people’s knowledge, skills, attitudes and behaviours in relation to health and physical exercise” (Papastergiou, 2009, p 603). However, Vander Schee and Boyles (2010) argue that exergames rather should be seen as a body pedagogy producing certain narrow meanings about health, and that the uncritical implementation of exergames in school is a problematic way to place commercial products in school. Consequently, there are differences in views regarding exergames in educational settings that are worth paying attention to in research about people’s learning about the body, physical activity and health.The aim of this paper is to investigate how images of the human body are expected to be learned when using exergames.The use of artifacts – physical objects made by humans – is a central part of human life. In fact, there are many activities that would not be possible to perform without the use of them. In schools, students learn to use paper and pencils, computers, vaulting-horses, footballs and so on. How and why artifacts are supposed to be used in educational settings is however not given beforehand (Cuban 1986). The use of artifacts mediates certain meanings about the view of learning and the goals and choices of content in education (Almqvist 2005, Quennerstedt et al in press).  In this paper, we will use discourse analytical strategies in order to analyse how meanings about the body are expected to be learned when playing exergames. The discourse analytical strategies involve an interest in how processes of discourse constitute how we experience or relate to ourselves as well as our environment (Laclau & Mouffe 1985). Discourses constitute what is possible to say or do as partial and temporal fixations (Foucault 1980). These fixations are imbued with power, values and ideologies. As Evans and colleagues argue: “/…/ health beliefs, perceptions and definitions of illness are constructed, represented and reproduced through language that is culturally specific, ideologically laden and never value free” (Evans et al 2008 p 46). MethodTo investigate what these games offer we have explored the manuals, the content, the animations of the games as well as the instructions and comments offered during game play. The empirical material consists of exergames most commonly used in schools: Wii fit and Wii sports (sports active). In the discourse analysis we have explored what is taken for granted in the empirical material in relation to other possible ways to argue. In this way we can explore what is included and excluded in the games and what is possible to think and act in relation to statements concerning the body. Expected OutcomesThe analysis shows how the logic of the game, its animations, instructions and feedback to the player, constitutes the ideal body as a physically active, well-balanced, slim and strong body. The use of the game, the balance board and the hand control, makes it possible to measure and register how the player follows this logic. The analysis also shows how the way the player is supposed to learn about the body is strongly influenced by behaviorism. In the paper we argue that this way of learning about the body is narrow and limited and that it is important to critically discuss the effects of the use of these games in schools. ReferencesAlmqvist, Jonas (2005).

  • Maximal Aerobic Power versus Performance in Two Aerobic Endurance Tests among Young and Old Adults
  • 2011
  • Ingår i: Gerontology. - 0304-324X. ; :Aug, s. 1-11
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Aerobic fitness is of great value for reducing risk of mortality and cardiovascular diseases. Objective: This study evaluated the performance in and correlations between a new test (five-minute pyramid test, 5MPT), the six-minute walk-test (6MWT) and maximal oxygen uptake (VO(2max)) among old and young adults. Methods: Forty-four habitually active adults (females and males), 23 old (64-79 years) and 21 young (20-32 years) participated. In the 5MPT, the participants moved back and forth along a short walkway (5.5 m) over boxes (height: 'old people' 0.42 m, 'young people' 0.62 m) arranged like an elongated step pyramid for 5 min. Power in the pyramid test (5MPT(power)) was calculated as the product of numbers of laps, body weight, gravity and highest box level divided by time. A 6MWT and a maximal cycle ergometer test for direct measurements of VO(2max) were also performed. In all tests heart rate, with on-line electrocardiography, and perceived exertion were recorded. Results: There was a strong correlation between the 5MPT(power) and VO(2max) for the entire group studied (r = 0.98), and each of the four subgroups old and young females and males separately (r = 0.78-0.98). Contrary to several earlier studies, especially involving people with various diseases, the present data showed that 6MWT cannot be used to predict VO(2max) among old females and young adults. The correlation with VO(2max) was weaker for the 6MWT than for the 5MPT(power). The relative performance values for the old compared to the young (ratio old/young × 100) were considerably lower in 5MPT(power) and VO(2max) (47-55%) than in distance and 'work' in the 6MWT (82-86%). Conclusions: The results, with age and gender variations, can be valuable information in health-fitness contexts, since measuring physical aerobic capacity is very significant in connection with risk evaluations of mortality and various diseases. The 5MPT is a rapid, functional, easy and inexpensive tool for predicting assessed maximal aerobic power.

  • Physical activity for persons with obesity—a health project reported
  • 2008
  • Ingår i: Forum on Public Policy Online. - Oxford Round Table. - 1938-9809. ; 4:Spring
  • Tidskriftsartikel (refereegranskat)abstract
    • In public health contexts, increased physical activity habits and fitness (aerobic and strength capacities) are positively related for promoting health and preventing  and treating common diseases/problems, including obesity and overweight. A strongly graded inverse association between physical activity and obesity has been shown both for adults and children. However, a lower mortality risk has been shown for those with greater weight but good aerobic capacity than for those of recommended weight but less fit. On the basis of a health project with physical activity for persons with or without obesity, the paper discusses evidence-based methods for promoting physical activity. General guidelines for the amount of physical activity for persons are described, as are the numerous physiological and medical advantages of physical activity. The economic benefits are also illustrated. The paper exemplifies methods of measuring physical activity habits and physical fitness. These two factors must be observed when showing improvements in public-health contexts, including groups with obesity.

  • Neuromuscular fatigue and recovery in elite female soccer effects of active recovery
  • 2008
  • Ingår i: Medicine & Science in Sports & Exercise. - 0195-9131. ; 40:2, s. 372-380
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: To investigate the time course of recovery from neuromuscular fatigue and some biochemical changes between two female soccer matches separated by an active or passive recovery regime. METHODS: Countermovement jump (CMJ), sprint performance, maximal isokinetic knee flexion and extension, creatine kinase (CK), urea, uric acid, and perceived muscle soreness were measured in 17 elite female soccer players before, immediately after, 5, 21, 45, 51, and 69 h after a first match, and immediately after a second match. Eight players performed active recovery (submaximal cycling at 60% of HRpeak and low-intensity resistance training at < 50% 1RM) 22 and 46 h after the first match. RESULTS: In response to the first match, a significant decrease in sprint performance (-3.0 +/- 0.5%), CMJ (-4.4 +/- 0.8%), peak torque in knee extension (-7.1 +/- 1.9%) and flexion (-9.4 +/- 1.8%), and an increase in CK (+ 152 +/- 28%), urea (15 +/- 2), uric acid (+ 11 +/- 2%), and muscle soreness occurred. Sprint ability was first to return to baseline (5 h) followed by urea and uric acid (21 h), isokinetic knee extension (27 h) and flexion (51 h), CK, and muscle soreness (69 h), whereas CMJ was still reduced at the beginning of the second match. There were no significant differences in the recovery pattern between the active and passive recovery groups. The magnitude of the neuromuscular and biochemical changes after the second match was similar to that observed after the first match. CONCLUSION: The present study reveals differences in the recovery pattern of the various neuromuscular and biochemical parameters in response to a female soccer match. The active recovery had no effects on the recovery pattern of the four neuromuscular and three biochemical parameters.

  • Physical activity before radical prostatectomy reduces sick leave after surgery - results from a prospective, non-randomized controlled clinical trial (LAPPRO).
  • 2016
  • Ingår i: BMC urology. - 1471-2490. ; 16:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Studies have reported that early physical rehabilitation after surgical procedures is associated with improved outcome measured as shorter hospital stay and enhanced recovery. The aim of this study was to explore the relationship between the preoperative physical activity level and subsequent postoperative complications, sick-leave and hospital stay after radical prostatectomy for prostate cancer in the setting of the LAPPRO trial (LAParoscopic Prostatectomy Robot Open).METHODS: LAPPRO is a prospective controlled trial, comparing robot-assisted laparoscopic and open surgery for localized prostate cancer between 2008 and 2011. 1569 patients aged 64 or less with an occupation were included in this sub-study. The Gleason score was <7 in 52 % of the patients. Demographics and the level of self-assessed preoperative physical activity, length of hospital stay, complications, quality of life, recovery and sick-leave were extracted from clinical record forms and questionnaires. Multivariable logistic regression, with log-link and logit-link functions, was used to adjust for potential confounding variables.RESULTS: The patients were divided into four groups based on their level of activity. As the group with lowest engagement of physical activity was found to be significantly different in base line characteristics from the other groups they were excluded from further analysis. Among patients that were physically active preoperativelly (n = 1467) there was no significant difference between the physical activity-groups regarding hospital stay, recovery or complications. However, in the group with the highest self-assessed level of physical activity, 5-7 times per week, 13 % required no sick leave, compared to 6.3 % in the group with a physical activity level of 1-2 times per week only (p < 0.0001).CONCLUSIONS: In our study of med operated with radical prostatectomy, a high level of physical activity preoperatively was associated with reduced need for sick leave after radical prostatectomy compared to men with lower physical activity.TRIAL REGISTRATION: The trial is registered at the ISCRTN register.

  • Amino Acid-induced S6K1 Activity In Human Skeletal Muscle Is Mediated By Increased mTor/Rheb Interaction 128 June 1, 11: 15 AM - 11: 30 AM.
  • 2016
  • Ingår i: Medicine And Science In Sports And Exercise 2016 May; Vol. 48 (5S Suppl 1), pp. 17.. ; s. 17-17

    • Cell culture studies have shown that amino acids activate mTORC1 signaling by increasing the interaction between mTOR and its essential activator Rheb. However, the existence of this mechanism in human skeletal muscle remains to be determined.PURPOSE: To determine if increased mTORC1 signaling in response to amino acids in human skeletal muscle is due to an increased interaction between mTOR and Rheb.METHODS: Eight well trained men performed resistance exercise on two separate occasions. In connection with the exercise, subjects were supplemented with flavored water (Pla) and essential amino acids (EAA) in a double-blind, randomized cross-over design. Muscle biopsies were taken in the vastus lateralis muscle before, immediately after and 90 and 180 min post exercise. Activity of the mTORC1 pathway was assessed by a radiolabeled in-vitro kinase assay for its immediate downstream target S6K1. Protein-protein interactions were determined by western blot following co-immunoprecipitation of mTOR with Rheb. Co-immunoprecipitation was performed on pooled muscle samples from three of the eight subjects.RESULTS: Activity of S6K1 remained unchanged immediately after exercise in both trials. However, at 90 min post exercise, S6K1 activity increased by approximately 2- and 8-fold (p<0.05) from baseline the Pla and EAA trials, respectively. At the 180 min time point, S6K1 activity remained elevated in both trials being approx. 3-fold higher in the Pla trial and 5-fold higher (p<0.05) in the EAA trial. The fold-change in mTOR and Rheb interaction largely resembled the activity pattern of S6K1 in both trials; in the Pla trial the fold-change was 0.9, 1.3 and 1.4 while in the EAA trial the fold-change was 1.6, 2.9 and 1.9 immediately after, 90 min after and 180 min after exercise, respectively.CONCLUSIONS: The large increase in S6K1 activity following EAA intake appears to be mediated by an increased interaction between mTOR and its proximal activator Rheb. This is the first time this mechanism has been demonstrated in human skeletal muscle.

  • The level of leisure time physical activity is associated with work ability-a cross sectional and prospective study of health care workers
  • 2013
  • Ingår i: Bmc Public Health. - 1471-2458. ; 13:855
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: With increasing age, physical capacity decreases, while the need and time for recovery increases. At the same time, the demands of work usually do not change with age. In the near future, an aging and physically changing workforce risks reduced work ability. Therefore, the impact of different factors, such as physical activity, on work ability is of interest. Thus, the aim of this study was to evaluate the association between physical activity and work ability using both cross sectional and prospective analyses.METHODS: This study was based on an extensive questionnaire survey. The number of participants included in the analysis at baseline in 2004 was 2.783, of whom 2.597 were also included in the follow-up in 2006. The primary outcome measure was the Work Ability Index (WAI), and the level of physical activity was measured using a single-item question. In the cross-sectional analysis we calculated the level of physical activity and the prevalence of poor or moderate work ability as reported by the participants. In the prospective analysis we calculated different levels of physical activity and the prevalence of positive changes in WAI-category from baseline to follow-up. In both the cross sectional and the prospective analyses the prevalence ratio was calculated using Generalized Linear Models.RESULTS: The cross-sectional analysis showed that with an increased level of physical activity, the reporting of poor or moderate work ability decreased. In the prospective analysis, participants reporting a higher level of physical activity were more likely to have made an improvement in WAI from 2004 to 2006.CONCLUSIONS: The level of physical activity seems to be related to work ability. Assessment of physical activity may also be useful as a predictive tool, potentially making it possible to prevent poor work ability and improve future work ability. For employers, the main implications of this study are the importance of promoting and facilitating the employees' engagement in physical activity, and the importance of the employees' maintaining a physically active lifestyle.

  • A qualitative investigation of commitment to dance findings from the UK Centres for Advanced Training.
  • 2014

  • Tidskriftsartikel (refereegranskat)abstract
    • Commitment to an activity forms an essential part of the talent development process, yet little is known about the reasons why young people commit to dance training. The aim of this study was to investigate the factors that affect young dancers’ commitment to a selective dance talent scheme. Semi-structured interviews were conducted with 19 committed dancers and transcripts were content analysed. Enjoyment was the most important factor relating to commitment, and stemmed from several sources such as self-expression, movement sensations and feelings associated with performing. Relationships with dance peers and teachers, parental support and the opportunities available on the scheme also enhanced commitment. While some potential barriers to participation were identified, such as concerns about injury, these seemed insufficient to affect the participants’ commitment. The results of the study may help educators to develop young dancers’ talents optimally by enhancing their commitment to training. [ABSTRACT FROM PUBLISHER]
