  • Experiences of returning to elite beach volleyball after shoulder injury
  • 2015
  • In: Journal of Exercise Rehabilitation. - : Korean Society of Exercise Rehabilitation. - 2288-176X .- 2288-1778. ; 11:4, s. 204-210
  • Journal article (peer-reviewed)abstract
    • The purpose of this study was to examine beach volleyball players' experience regarding shoulder injury and how it affects their return to play. To achieve the research aims a qualitative design with semi-structured interviews had been conducted, five elite beach volleyball players, four men and one woman aged 27-42 participated in the study. All participants had suffered a severe shoulder injury, with absence from training and competing for at least 28 days. The findings of this study indicate that it is the individual's inner motivation, together with a clear goal and support from the community, family, teammate and coach that are the most important factors when going through rehabilitation and getting back to playing beach volleyball after a shoulder injury. All participants had been affected by their injury in some way; some of the participants had been affected in a positive way since they had become mentally stronger and had developed better volleyball technique after rehabilitation. The conclusions of this study indicate that there are three distinct factors that increase the chances of getting back to playing beach volleyball after shoulder injury; it is the players' self motivation, together with a clear goal and support from the community.

  • The effects of introducing Tabata interval training and stability exercises to school children as a school-based intervention program
  • 2019
  • In: International Journal of Adolescent Medicine and Health. - : Walter de Gruyter. - 0334-0139 .- 2191-0278. ; 31:4, s. 1-11
  • 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.

  • ACL diagnosis – The correlation between Rolimeter and MRI
  • 2020
  • In: Sports Orthopedics and Traumatology. - : Elsevier. - 0949-328X .- 1876-4339. ; 36:3, s. 278-283
  • 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.

  • Physical Fitness, Dietary Habits and Substance Misuse : A Cross-Sectional Analysis of the Associations in 7,600 Swedish Adolescents
  • 2022
  • In: Physical Activity and Health. - : Ubiquity Press. - 2515-2270. ; 6:1, s. 26-37
  • Journal article (peer-reviewed)abstract
    • Introduction: Adolescence is a period of rapid physical, psychological and social changes and a time when habits are formed. This study aimed to investigate the correlation between physical fitness, alcohol consumption, tobacco consumption and dietary habits among adolescents according to the Swedish Physical power, Mental harmony and Social capacity profile (FMS profile).Methods: Data were collected from Swedish high school students, 1st – 3rd grade (16–19 yrs), both genders, overall, 7,600 Swedish adolescents using the FMS profile, comprising physical tests and questionnaires concerning lifestyle factors (e.g. physical fitness, dietary habits, alcohol and tobacco use). Participants included in this study met the requirements of inclusion, which were having a complete set of data, e.g. had undergone all physical tests and answered all questionnaires.Results: A total of 13% self-reported cigarette smoking, while 37% self-reported alcohol consumption. Adolescents who smoked were older (t-test = 9.09,p< 0.001), heavier (t-test = 4.58,p< 0.001) and had greater BMI (t-test = 3.96,p< 0.001). Adolescents who consumed alcohol were older (t-test = 8.78, p < 0.001), heavier (t-test = 4.03,p< 0.001) and taller (t-test = 3.77,p< 0.001). Significant differences were found for all fitness factors, with better mobility, strength and balance in adolescents who did not smoke compared to smokers (Mann Whitney Z test = 2.77, 7.13, 5.77, respectively; allp< 0.001). Regularity of meals and avoidance of sweets and cakes were less prevalent in adolescents who smoked (OR (95% CI): 0.63 (0.59–0.68), 0.71 (0.66–0.77), respectively).Conclusion: Among Swedish adolescents, tobacco and alcohol use increase with age. However, physical fitness is consistently protective against tobacco consumption, and dietary habits are mostly protective against alcohol consumption. Physical fitness and low alcohol and tobacco consumption are possible health factors.
