- Purpose. The aim of this study was to evaluate the 2-year outcome of a multidisciplinary rehabilitation programme for working-age people, regarding sick leave and mental health. Method. The test persons consisted of 40 women and 20 men (mean age 46.8 +/- SD 7.9) with musculoskeletal disorders, mainly neck and back pain. The rehabilitation programme was individually adapted and consisted of physical activity in several forms, relaxation, theoretical and practical education and individual guidance. Before, during and after the programme all participants were evaluated with the Global Self-Efficacy Index, Hospital Anxiety and Depression Scale, and stress test. Results. At the 2-year follow-up full-time sick leave had decreased by 37% (p < 0.0001) in the women, and by 25% (p < 0.05) in the men. Both women and men showed an increased quality of life (QoL) and decreased anxiety, depression and self-experienced stress at the 2-year follow-up compared with the start of the rehabilitation programme. Conclusions. The most important conclusion was that the effects of the rehabilitation programme persisted for up to 2 years. At 2 years the majority of the participants were still physically active, their QoL was increased, and most participants had returned to work.

- 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.

- PURPOSE: Muscle strength, endurance and range of movement of the cervical spine in a group of Swedish Air Force jet pilots (AF) and in a reference group of conscripts doing their military service (RG) were compared. METHODS: We tested 30 (AF) 24-42 yr and 33 (RG) 19-22 yr. A questionnaire was used to document complaints. Maximum voluntary isometric muscle strength of the flexor and extensor muscles of the cervical spine and sub-maximum isometric endurance in the flexor and extensor muscles were measured. RESULTS: Eleven AF (37%) and four RG (12%) had experienced discomfort in the neck within the previous year. The pilots' flexor and extensor muscle strength (47 Nm and 65 Nm) was superior to that of the conscripts (36 Nm and 59 Nm) (p = 0.0001, p = < 0.05, respectively). However, the RG group had greater isometric endurance in the flexor muscles than AF (p = < 0.05) and greater neck rotation (p = <0.005). There was no difference between the two groups in the other variables. CONCLUSION: Differences between the groups with regard to muscle strength and endurance might depend on variations in work-related physical muscle strain, and/or differences in fiber composition in the muscles, which might be reflected by pilot selection procedures.

- AIM: Children and adolescents in the industrial world are becoming lessphysically active and are adopting a sedentary lifestyle in front of computersand TV. The aim of the present investigation was to determine self-relatedhealth, physical activity, prevalence of overweight and body complaints inhigh school students in Norway, and to compare students in academicprograms with those in vocational programs. METHODS: Seven hundred andtwo high school students aged 16-19 years were included in the study. Aquestionnaire was completed in three high schools and included questionsabout weight and height, health, physical activity, type of physicalactivity/sport, intensity, possible injuries or complaints during the last threemonths. RESULTS: Twenty three percent of the students suffers fromoverweight/obesity are at risk of being overweight. Males reported betterhealth than females (P<0.02). Sixty-six percent of the study group reportedbody complaints during the last three months, a higher number of femalesthan males (P=0.001). Students in vocational programs reported poorer selfrelatedhealth than those in academic programs and the males reportedbetter self-related health generally than females. Furthermore, there were ahigher level of prevalence of overweight students in vocational programsthan academic programs (P=0.039). CONCLUSION: It is important to make iteasy for school children and adolescents to do physical activity at school andduring leisure time in order to prevent overweight and obesity as well aschronic diseases later in life.

- Adolescents in the industrial world are becoming less physically active and are increasingly adopting a sedentary life-style in front of computers and television screens. OBJECTIVE: to determine self-related health, physical activity, sleeping habits, prevalence of overweight, and body complaints in Australian senior high school students. METHODS: Participants were 466 high school students aged 15-17 years enrolled in academic and vocational programs. A questionnaire was completed at 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. RESULTS: Seventy seven percent of the high school students participated in sports on a regular basis. Compared with vocational programs, more males and females in academic programs participated in sports (71% and 80% respectively) (p = .036). Males reported significantly better health than females (p < .0001). 65% of the study group reported body complaints during the last 3 months. A higher number of females than males reported complaints about the back (p = .007) and the hip (p = .05). Good sleep was reported in 82.1% of males and in 76.6% of females. In males, 44.3% were often sleepy in the daytime (females 56.6%, p < .01). CONCLUSIONS: Underweight, physical activity and good sleep are factors with significant positive effect on good health, whereas overweight is 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.

Tidskriftsartikel (refereegranskat)abstract
- The aim of the present investigation was to test the reliability of two sports related functional tests, a speed test (slalom-test) and an agility test (hurdle-test). Eleven athletes aged 11 years (8 boys, 3 girls) participated voluntarily in the study. All subjects completed four different test sessions for both the slalom-test and the hurdle-test using six standard track hurdles placed at 2-m intervals along a 12-m length of track. There were no significant differences between testing sessions for either the slalom-test (P=0.99) or the hurdle-test (P=0.96), showing no systematic variation between test times. The intraclass correlation coefficients were 0.96 and 0.90 respectively, indicating a good reliability. We conclude that the slalom-test and the hurdle-test are reliable sports related functional tests for measuring speed and agility in groups of young athletic individuals.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this investigation was to study self-related health, physical activity and level of exertion, as well as body complaints in Swedish high school students. A total of 993 high school students aged 16–19 years participated in the study. A questionnaire was completed at school and included questions about self-related health, physical activity behavior, type of physical activity/sport, intensity, duration, possible injuries or complaints, and absence from physical training at school, during the last 3 months. The results showed that 26% of the high school students participated in sports on a regular basis. Males reported significantly better health than females (p < 0.0005). A significantly higher number of females participated in physical activities at a lower level of effort (p < 0.0005) and a higher number of males trained at a higher level of effort (p < 0.005). Sixty-one percent reported body pain during the last 3 months, representing a higher number of females than males (p = 0.03). A higher number of females than males reported complaints from the back (p = 0.002), the knees (p = 0.015), the neck (p = 0.001), and the hip (p = 0.015). Females with body complaints reported poorer health than those without complaints. There was a correlation between poor self-related health and a lower level of physical effort (0.219; p < 0.001). The results showed that the prevalence of musculoskeletal symptoms was high in this population and demonstrated a certain association with self-related health. Therefore, it is important to make it easy for adolescents to perform physical activity at school and during their leisure time in order to prevent chronic diseases.

- Aim. The purpose of this study was to compare physical health, physical activity and location for possible symptoms in high school students with cross-country skiers of the same age from ski high schools. Another aim was to study back pain with regards to influence on skiing.Methods. The subjects studied were: 92% (n=120) of all Swedish cross-country skiers at ski high schools and 68% (n=993) of regular high school students from the North part of Sweden answered a reliable questionnaire (r=1) with regards to health, physical activity and location of possible symptoms/injuries during the last 3 months. Furthermore, the skiers answered questions on possible ski related back pain.Results. All skiers were active also in other sports compared with 26% of the controls and at considerably higher levels of physical effort than the controls; 92% of the skiers and 76% of the controls described themselves as healthy, meaning "very good" or "good" (P=0.0001); 55% of the skiers and 64% of the controls reported recent symptoms (P=0.06); 47% of the skiers reported previous or present complaints of back pain, mainly low back pain, which could be relieved by changing body position from a flexed to a more extended one while skiing, and 77% reported their back pain to disappear during rest.Conclusion. These results show the need for encouraging regular high school students to participate in sport. It also shows the importance of introducing preventative strategies regarding back pain to long-distance cross-country skiers, who are exposed to a prolonged flexed position of their back.

- This study investigated the association between spinal alignment, mobility of the hips and the thoracic spine and low back pain in adolescent cross-country skiers. Cohort of 51 elite cross-country skiers from a cross-country skiing high school in Sweden participated in the study. Sagittal spinal alignment, active range of motion in flexion, extension and rotation of the thoracic spine as well as passive and active extension of the hips were measured. The participants also completed a questionnaire regarding training, competition, skiing technique and occurrence of low back pain. A simple linear regression was calculated to predict pain score based on thoraco-lumbar relation, with a significant (P<0.05) regression equation of y=-0.069x+2.280 (standard error of estimate, 0.034). Participants with greater lordosis than kyphosis were more likely to suffer from low back pain than subjects without this offset. Thoracic mobility and passive or active hip extension showed no correlation with low back pain. Sagittal spinal alignment seems to be related with low back pain among young elite cross-country skiers. This study shows that range of motion of the thoracic spine and hips do not have an effect on the prevalence of low back pain in this population.

The elite cross-country skier : clinical and sports related functional tests, dance training, injuries and self-related health
- 2003
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The general aim of this thesis was to study cross-country skiers regarding the effect of dance training on joint mobility and muscle flexibility of the spine, hip and ankle and on speed and agility. Another aim was to perform test-retests of joint mobility and muscle flexibility of the hip and of sports related functional tests. A further aim was to compare high school students with age matched cross-country skiers concerning physical health, activity and location for possible symptoms/injuries. Finally, the aim was to study back pain regarding influence on skiing in high school cross-country skiers. Athletes aged 11 years (8 boys, 3 girls) completed four different test sessions for two sports related functional tests, emphasising speed and agility, the slalom-test and the hurdle-test. No significant differences were found between testing sessions for either the slalom-test (p=0.99) or the hurdle-test (p=0.96). Healthy athletic volunteers (5 males, 5 females) on average 30±16 years performed four joint motion and muscle flexibility tests at three times with one day intervals. The results using intra class correlation coefficients showed the following values 0.99 (knee flexion with hip extended), 0.88 (hip extension with knee extended), 0.93 (hip flexion with knee extended), and 0.53 (a combination of abduction and external rotation of the hip). Subsequently, three out of the four tests showed a good reliability. A group of young (aged 12-15 years) cross-country skiers (n=10) performed dance training during 8 months. Another aged matched group of cross-country skiers (n=10) served as a reference group. Before, during and after the intervention period joint mobility and muscle flexibility of the spine, hip and ankle as well as sports related functional tests were performed in all skiers from both groups. The results showed improvements in speed, agility and range of motion of the spine in most of the studied parameters. A group of elite cross-country skiers (aged 19±3.9 years) either performed additional preseason dance training for 3 months (n=16) or served as a reference group (n=10). Before and after the intervention period joint mobility and muscle flexibility of the spine, hip and ankle and sports related functional tests were performed in all skiers. Prior to dance training the intervention group showed a slight impairment of range of motion of the spine and the relationship between kyphosis of the thoracic and lordosis of the lumbar spine compared with the reference group. After dance training these parameters were improved and a tendency towards a positive effect on back pain was also found. Using a questionnaire cross-country skiers from ski high schools (n=120) were found to be considerably more physical active in as well other sports as skiing when compared with age matched ordinary high school students (n=993). In comparison with controls a higher number of ski high school students described themselves to be physically healthy. Half of the cross-country ski students complained of back problems, mainly low back pain, while skiing and above all during diagonal skiing.

- Objectives To evaluate possible changes in spinal curvature over a period of 5 years of an elite cross-country skiing squad, and to study whether there are any differences in this respect between individuals who report low back pain and those how do not. Participants Fifteen young cross-country skiers (M age=13.6±0.9) participated voluntarily throughout the entire study period. Main outcome measures Debrunner's kyphometer was used for measuring the difference between thoracic kyphosis and lumbar lordosis of the spine. All subjects also answered a questionnaire including questions about ski-related low back pain, the amount of ski training, and participation in other sports. Results The results at the end of the 5-year period comprise data from 15 skiers (M age=18.5±0.9 years). The relationship between thoracic kyphosis and lumbar lordosis increased from 3.5° to 13.1°, respectively (p=0.0001). Of the 15 elite cross-country skiers, seven reported low back pain at the 5-year examination. At the 5-year follow-up, skiers with low back pain showed significantly higher relationship between thoracic kyphosis and lumbar lordosis than did those skiers without low back pain, 18.2° and 10.5°, respectively (p=0.035). Of the eight elite cross-country skiers without low back pain, seven were also involved in other sports (p=0.005). Conclusions Based on these findings, our advice is that adolescent cross-country skiers also should participate in other physical activities besides cross-country skiing.

Forskningsöversikt (refereegranskat)abstract
- The extent and depth of traumatic brain injury (TBI) remains a major determining factor together with the type of structural insult and its location, whether mild, moderate or severe, as well as the distribution and magnitude of inflammation and loss of cerebrovascular integrity, and the eventual efficacy of intervention. The influence of exercise intervention in TBI is multiple, ranging from anti-apoptotic effects to the augmentation of neuroplasticity. Physical exercise diminishes cerebral inflammation by elevating factors and agents involved in immunomodulatory function, and buttresses glial cell, cerebrovascular, and blood-brain barrier intactness. It provides unique non-pharmacologic intervention that incorporate different physical activity regimes, whether dynamic or static, endurance or resistance. Physical training regimes ought necessarily to be adapted to the specific demands of diagnosis, type and degree of injury and prognosis for individuals who have suffered TBI. © 2012 John Wiley & Sons A/S.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to evaluate the symmetry of anthropometry and muscle function in cross-country skiers and their association to vertical jumping power. Twenty cross-country skiers were recruited (21.7 +/- 3.8 yrs, 180.6 +/- 7.6 cm, 73.2 +/- 7.6 kg). Anthropometric data was obtained using an iDXA scan. VO2max was determined using the diagonal stride technique on a ski treadmill. Bilateral functional tests for the upper and lower body were the handgrip and standing heel-rise tests. Vertical jump height and power were assessed with a counter movement jump. Percent asymmetry was calculated using a symmetry index and four absolute symmetry index levels. At a group level the upper body was more asymmetrical with regard to lean muscle mass (p = 0.022, d = 0.17) and functional strength (p = 0.019, d = 0.51) than the lower body. At an individual level the expected frequencies for absolute symmetry level indexes showed the largest deviation from zero for the heel-rise test (chi 2 = 16.97, p = 0.001), while the leg lean mass deviated the least (chi 2 = 0.42, p = 0.517). No relationships were observed between absolute symmetry level indexes of the lower body and counter movement jump performance (p > 0.05). As a group the skiers display a more asymmetrical upper body than lower body regarding muscle mass and strength. Interestingly at the individual level, despite symmetrical lean leg muscle mass the heel-rise test showed the largest asymmetry. This finding indicates a mismatch in muscle function for the lower body.

- 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.

- 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.

- 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.

- Aim: Physical conditioning of youth has always been a controversial topic as it raises ethical, physiological, and medical issues. Current recommendations and guidelines suggest that strength training is a relatively safe and worthwhile method in conditioning youth. This, however, requires well-informed coaches who follow age-appropriate strength training recommendations and guidelines, compiles well-designed strength training programs, and provides qualified supervision and instructions. The purpose of this study was to investigate coaches’ awareness of current recommendations and guidelines regarding strength training for youth.Method: A total of 39 football (US: soccer) coaches (34 males and 5 females) training boys in age groups 8–12 years were included in this study. Data were collected using an attitude statement questionnaire, and the assertions were based upon current recommendations and guidelines.Results: The results revealed significant differences among coaches in terms of knowledge of important aspects of strength training for youth.Conclusions: The results suggested that coaches in the present study were not aware of the latest recommendations and guidelines regarding strength training for youth.

Tidskriftsartikel (refereegranskat)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
-
Ingår i: International Journal of Environmental Research and Public Health. - : MDPI. - 1661-7827 .- 1660-4601. ; 19:19

Tidskriftsartikel (refereegranskat)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.

Tidskriftsartikel (refereegranskat)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.

- The manner in which health professionals and coaches act and decide on treatment and prognosis can influence athletes in a way that not only strengthens them, but it can also reduce their confidence in their own ability. The purpose was to determine who has the responsibility for child and adolescent psychosocial support needed in connection with a severe sports injury as well as investigate whether coaches, physiotherapists and parents are aware of the support that is needed. Qualitative interviews with coaches, parents and physiotherapists with experience of serious sports injuries in young people aged 12 to 16 years old from different sports were analysed using content analysis. The study showed that all actors independently imparted communication as being the major problem and indicated that the role of a coordinator was missing. They imparted cognitive, emotional and behavioural reactions in children, which were considered to be more common in younger children as indicated in previous studies. Coaches felt they had lack of education and time; parents described their disappointment in caregivers and personality changes in their children in connection with the injury. Physiotherapists felt that rehabilitation was often served as a substitute for the sport and that they therefore had greater responsibility for the child than they had been educated for. Results should be communicated to participants who are involved in children's and adolescent's sports to increase their knowledge and thus allow them to be able to give our children the best possibility, regardless of whether they return to the sport or not.

Tidskriftsartikel (refereegranskat)abstract
- Objectives The heel-rise test is used to assess the strength and endurance of the plantar flexors in everyday clinical practice. However, several factors may affect outcomes, including sex, age, body mass index and activity level. The aims of this study were to revisit the reliability and normative values of this test, and establish normative equations accounting for several factors. Interventions Subjects performed single-legged heel rises to fatigue, standing on a 10 degrees incline, once on each leg. A subset of subjects (n = 32) repeated the test 1 week later. Reliability was quantified using intraclass (ICC) correlation coefficients and BlandAltman plots {mean difference [95% limits of agreement (LOA)]}, whereas the impact of sex, age, body mass index and activity level on the number of heel rises was determined using non-parametric regression models. Results The test showed excellent reliability (ICC = 1.0 right leg, 1.0 left leg), with mean between-day differences in the total number of heel-rise repetitions of 0.2 (95% LOA -6.2 to 6.5) and 0.1 (95% LOA -6.1 to 6.2) for right and left legs, respectively. Overall, males completed more repetitions than females (median 24 vs 21). However, older females (age >60 years) outperformed older males. According to the model, younger males with higher activity levels can complete the most heel rises. Conclusions The heel-rise test is highly reliable. The regression models herein can be employed by clinicians to evaluate the outcomes of heel-rise tests of individuals against a comparable normative population.

- Compliance with a rehabilitation program is significant among athletes following a sports injury. It is also one of the main factors that influence the rehabilitation process; moreover, the outcome is also influenced by the athlete's motivation. It is primarily an autonomous motivation, resulting in rehabilitation adherence. The aim of this study was to investigate the perceived motivation of female football players during rehabilitation after a sports injury and the extent to which these motivating factors were autonomous. Qualitative interviews, based on a semistructured interview guide with injured female football players undergoing rehabilitation, were analyzed using content analysis. The motivational factors that were described were their set goals, social support as well as external and internal pressures during rehabilitation. The perceived autonomy varied somewhat but overall, they experienced external motivation; therefore, the behavior was not entirely self-determined. Results are expected to provide a better understanding of women football players' motivation in relation to their rehabilitation; hence, physiotherapists and coaches who are part of the rehabilitation process can contribute by increasing the autonomous motivation, thus, improving the compliance and outcome of the rehabilitation.

Tidskriftsartikel (refereegranskat)abstract
- Few studies have investigated the incidence of injuries in kayakers. The aim was to study the prevalence of shoulder pain in competitive flatwater kayakers and to evaluate any differences in range of motion or scapula stability of the shoulder joint among kayakers with or without the history of shoulder pain. Thirty-one kayakers were participated in the study, and a questionnaire including background data was used. Shoulder range of motion was measured with a goniometer, and the participants were observed for scapula dyskinesis in flexion and abduction. Of the participating kayakers, 54.8% (n=17) had experienced shoulder pain. Kayakers who had experienced shoulder pain showed a significantly lower degree of internal rotational range of motion versus kayakers with no reported shoulder pain, with a mean degree of internal rotation in the right shoulder 49.3 vs 60.0 (P=0.017) and the left shoulder 51.9 vs 66.0 (P=0.000). Kayakers who had experienced shoulder pain were also observed with a scapular dyskinesis (n=15 of 17 kayakers) to a significantly higher degree (P=0.001) than kayakers with no reported shoulder pain. Findings suggest that screening for scapular dyskinesis and testing for rotational range of motion in the shoulder joint is essential in order to treat and maybe prevent shoulder pain in kayakers.

Ingår i: Journal of Psychology & Psychotherapy. - : OMICS Publishing Group. - 2161-0487. ; 5:4
-
Tidskriftsartikel (refereegranskat)abstract
- Objective: Prevention of alpine ski injuries is less studied when it comes to psychological aspects. The aim of the present investigation was to study if there were any relationships between some personality traits and alpine ski injuries. Additionally, find out if gender could be a significant factor in these relationships. Methods: 298 alpine skiers (139 males, 159 females) at a Swedish ski high school completed the Swedish universities Scales of Personality (SSP). SSP is a self-report personality inventory containing 91 items divided into 13 subscales regarding e.g. stress susceptibility, impulsivity and sensation seeking behavior. Three groups of skiers were analyzed those without any injuries, with one injury, and with two or more injuries. Results: Injury rate was significantly related to stress susceptibility (p=0,046) with higher values for the uninjured skiers and the lowest values for the group with higher injury rates (for both males and females). No signficant relationships were found between adventure seekiing, impulsivity, and anxiety proness and injury rate. Conclusion: Stress susceptibility seems to be a preventing factor in alpine skiing injuries among skiers 16-20 years old.

- Background: Physical activity and sport participation often decline during adolescence. Aim: To investigate if physical exercise during 6 months could lead to a positive behavior of physical activity, improve physical fitness and self-related health in physically inactive female high school students. Methods: A prospective cluster-randomized controlled intervention study included 104 physically inactive female high school students, 60 in an intervention group and 44 controls. At baseline there were no group differences regarding self-related health. The intervention group exercised at least once per week. A questionnaire and physical fitness tests were used for evaluation, at baseline and 6 months later. Results: The intervention group improved their self-related health compared with the controls (P = .012). When divided into a regular (n = 27) and an irregular training group (n = 33) the regular training group improved their self-related health compared with the controls, while the irregular training group did not differ from the other groups. Maximal oxygen consumption was improved in the intervention group compared with the controls (P < .001). No group differences were found in muscle strength and endurance. Conclusion: Physical exercise at least once per week during 6 months improved physical fitness (maximal oxygen consumption) and self-related health in physically inactive female high school students.

- BACKGROUND: Physical activity provides fundamental health benefits and plays a positive role in physical well-being. The aim of this present study was to investigate whether a 6-month physical activity program could influence physical self-esteem and frequency of physical activity in physically inactive female high school students in short- and long-term periods and whether personality traits were related to physical activity behaviour and compliance with the program. METHODS: The study was a cluster-randomised controlled intervention study including 104 physically inactive female high school students aged 16-19 years, 60 females in an intervention group and 44 females in a control group. The intervention group exercised at sport centres at least once per week during a 6-month period. Questionnaires were used for evaluation. RESULTS: At a 6-month follow up, the intervention group improved physical self-perception in all subdomains and significantly improved physical condition, physical self-worth and self-related health compared to the control group. At 1-year follow up, 25 females out of 53 females were still physically active, and all ratings remained almost the same as at the 6-month follow up. There were no particular personality traits that were dominant in the groups. CONCLUSION: A 6-month physical activity program can positively influence physical self-esteem and the frequency of physical activity, both from a short- and long-term perspective.
