- Adolescents are becoming less physically active and are increasingly adopting a sedentary life-style in front of computers and television screens. In this chapter we look at self-related health, physical activity, sleeping habits, the prevalence of overweight and body complaints in two senior high schools with questions about weight and height, health, physical activity, type of physical activity/sport, intensity, sleeping habits and possible injuries or complaints during the last three months. Seventy seven percent % of the high school students participated in sports on a regular basis. In academic programs compared to vocational programs, more males and females in academic programs participated in sports (71% and 80% respectively). Males reported significantly better health than females, but 65% reported body complaints during the last three months. A higher number of females than males reported back and hip complaints. Good sleep was reported in 82.1% of the males (76.6% of the females). In males 44.3% were often sleepy in the daytime (females 56.6%). Underweight, physical activity and good sleep were found to be factors with significant positive effect on good health, whereas overweight was a negative factor. Proper sleep habits and higher physical activity levels should be promoted among high school students and TV viewing time and video game use restricted. Additionally, schools should provide opportunities for young people to participate in a wider range of physical activities that address their individual needs, while promoting the health benefits of engaging in regular exercise.

- Context:The physical and mental demands of an elite football player are complex, which may explain why injuries are commonin football. At elite level, muscle injuries of the lower-extremity are the most common among male football players, and theresearch hitherto is limited. Objective: To investigate whether personality traits affect the incidence of muscle injuries amongmale football players from the first league in Sweden. Design: Prospective cohort study. Participants: A male football team fromthe first league in Sweden was prospectively followed, in terms of muscle injuries of the lower-extremity during 8 seasons,between 2007 and 2015. Intervention: All muscle injuries included in this study were evaluated and diagnosed withultrasonography. Players from the team filled out the Swedish Universities Scales of Personality questionnaire. SwedishUniversities Scales of Personality questionnaire consists of 91 items and is divided into 13 categories. Main Outcome Measures:The raw values of each scale were linearly transformed to T scores, having a mean (SD) of 50 (10). All variables weresummarized with standard descriptive statistics, such as frequency, mean, and SD. As data were of interval scale and no variabledistribution was severely skewed, differences between noninjured players, rarely injured players, and frequently injured playerswere analyzed with 1-way analysis of variance with post hoc tests by Tukey honestly significant difference test. Results:No significant difference in personality traits were observed between noninjured players, rarely injured players, and frequentlyinjured players regarding number of muscle injuries (P > .05). However, a trend (P = .07) was seen, where frequently injuredplayers scored higher on stress susceptibility than rarely injured players. Conclusion: A player’s stress susceptibility should betaken into consideration by the player, coaches, and medical staff when assessing the risk of a muscle injury. Also, preventivemeasures available for these players may need to be considered.

Journal article (peer-reviewed)abstract
- Background Physical activities during leisure time as well as school hours have changed over the past few years, with adolescents being less physically active and adopting a sedentary lifestyle. Objective The overall objective of this mixed-methods study was to evaluate the feasibility of introducing a 4-min Tabata interval training into a lower secondary school context. A further aim was to evaluate the possible effects on: coordination, balance, and strength. Methods The study was conducted as an intervention study with a mixed-method approach. Forty-three children, aged 7-9 years, participated in the intervention group. Additionally, 13 children were recruited as a control group. The intervention itself was delivered by the teachers and was performed for 4-min every day in a classroom setting. All participants performed physical tests before and after the intervention period to evaluate the Tabata training. After the completion of the 6-week Tabata interval training, the four teachers were interviewed. Results The push-ups (p = 0.004), kneeling push-ups (p = 0.03), and standing long jump (p = 0.01) improved in the intervention group after 6 weeks. No differences were observed between the genders. The teachers experienced that it worked well to integrate the Tabata interval training in the classroom setting. Conclusion After 6 weeks, a school-based Tabata intervention program improved physical performance. The teachers saw no obstacles in including the Tabata intervention program in a classroom setting and pointed out several positive aspects such as an increased energy level and development in the children's movement patterns.

Test-retest reliability of repeated knee laxity measurements in the acute phase following a knee trauma using a Rolimeter
- 2017

In: Journal of Exercise Rehabilitation. - : Korean Society of Exercise Rehabilitation. - 2288-176X .- 2288-1778. ; 13:5, s. 550-558

Journal article (peer-reviewed)abstract
- The purpose was to examine the test-retest reliability of the Rolimeter measurement procedure in the acute time phase, following a substantial knee trauma. In total, 15 participants with acute knee trauma were examined by one single observer at three different time-points with the Rolimeter using a maximum force. The selected time-points were: baseline (0–7 days after the trauma), midpoint (3–4 weeks after the trauma), and endpoint (3–4 weeks after the trauma). The anterior-posterior displacement was recorded where the endpoint evaluation was used as the reference value. The mean anterior laxity scores remained constant over the measurement time-points for both knees, with an anterior laxity that was 2.7 mm higher (on average) in the injured than the noninjured knee (9.5 mm vs. 6.8 mm). The mean difference (i.e., bias) between laxity scores, for the injured knee, measured at endpoint versus baseline was 0.2±1.0 mm and −0.2±1.1 mm when measured at endpoint versus midpoint, with average typical errors of 0.7 and 0.8 mm and intra-class correlations that were very strong (both r=~0.93). For the same comparisons on the noninjured knee, systematic bias was close to zero (0.1±0.3 and −0.1±0.3 mm, respectively), and both the intra-class correlations were almost perfect (r=~0.99). The current study implicates that repeated Rolimeter measurements are relatively reliable for quantifying anterior knee laxity during the acute time-phases following knee trauma. Hence, the Rolimeter, in combination with manual tests, seems to be a valuable tool for identifying anterior cruciate ligament injuries.

Journal article (peer-reviewed)abstract
- Background: Sports activities are the most common way to get an anterior cruciate ligament (ACL) injury. Correct diagnoses in the early phase after the knee injury is essential to establish a rehabilitation plan and, in the case of ACL-diagnosis, to avoid re-injuring the knee with increased risk of meniscal tears and/or osteoarthritis. The aim was to determine whether it is possible to confirm an ACL-injury with the Rolimeter measurements in the acute phase of a knee trauma, and if it cor-relates with magnetic resonance imag-ing (MRI) findings or arthroscopy. Material and Methods: Thirty-four patients with an acute knee trauma, 20 women and 14 men, aged from 15–44 years, with a mean age of 24.8 (SD 7.3) participated. All were examined with the Rolimeter in the acute phase after a suspected ACL-injury. They also underwent MRI (n = 29) or arthroscopy (n = 5) wherein the injury was confirmed. Results: A great consistency was seen in diagnosing the ACL-injuries with the Rolimeter measurement compared to MRI findings. The specificity (90.9%), sensitivity (91.3%), accuracy (91.2%), PPV (95.5%) and NPV (83.3%) were high in this study. Conclusions: The Rolimeter measure- ment procedure is a safe and quick method in diagnosing an ACL-injury in the acute phase. Further studies should focus on larger cohorts and compare an early diagnosis to patient related outcome measures and societal/economical gains.

Association between Physical Fitness, Physical Activity Level and Sense of Coherence in Swedish Adolescents : An Analysis of Age and Sex Differences
- 2022
-
In: International Journal of Environmental Research and Public Health. - : MDPI. - 1661-7827 .- 1660-4601. ; 19:19

Journal article (peer-reviewed)abstract
- Introduction: The aim of this study was to investigate the association between physical fitness, physical activity, and sense of coherence (SOC) in Swedish adolescents (n = 2028 males, n = 1287 females) aged 14 to 18 using a cross-sectional design. Methods: Using the Swedish Physical power Mental harmony and Social capacity (FMS) student profile, participants performed physical tests measuring their cardiovascular ability (CV) and muscular strength. Questionnaires were used to measure physical activity levels (PA), the participation in organized physical training, sedentary behavior (SB), screen time, and SOC value. Multiple linear regression analyses were used to analyze the association between SOC and independent variables. Results: The regression analyses explained a small, shared variance between SOC and the independent variables in boys (4.3%) and girls (3.3%). SB showed a positive association with SOC both in girls (β = 0.114, p = 0.002) and boys (β = 0.109, p = 0.013). Abdominal strength was positively associated, while VO2max was inversely associated, with SOC (β = 0.113, p = 0.022; β = −0.109, p = 0.026, respectively) in boys. Girls had poorer fitness than boys did across all age groups except at age 18. PA levels decreased from age 14 to 18 in girls and boys, but without differences between sexes. Abdominal strength decreased from age 14 to 18 in girls and boys. In general, girls had lower SOC than boys across all age groups.Conclusions: Poor sedentary behavior was significantly associated with weaker SOC for both genders, indicating overall physical activity as the most important factor for stronger SOC. However, emotional support in vulnerable environments may have a bigger impact than physical activity or sedentary behavior on the SOC value for adolescents.

- I antagningen till ett riksidrottsgymnasium ingår fysiska tester. Vår analys av tester från gymnasiet i Växjö visar att de möjligen kan förutsäga idrottslig framgång som senior, men sambanden är så svaga att de inte bör vara helt avgörande vid antagningen.
