RESUMO
BACKGROUND: Active travel and school settings are considered ideal for promoting physical activity. However, previous research suggests limited effect of school-based interventions on overall physical activity levels among adolescents. The relationship between physical activity in different domains remains inconclusive. In this study, we examined the effects of adding two weekly hours of school-based physical activity on active travel rates. METHOD: We analyzed data from 1370 pupils in the 9th-grade participating in the cluster RCT; the School In Motion (ScIM) project. Intervention schools (n = 19) implemented 120 min of class-scheduled physical activity and physical education, in addition to the normal 2 hours of weekly physical education in the control schools (n = 9), for 9 months. Active travel was defined as pupils who reported walking or cycling to school, while motorized travel was defined as pupils who commuted by bus or car, during the spring/summer half of the year (April-September), or autumn/winter (October-February). The participants were categorized based on their travel mode from pretest to posttest as; maintained active or motorized travel ("No change"), changing to active travel (motorized-active), or changing to motorized travel (active-motorized). Multilevel logistic regression was used to analyze the intervention effect on travel mode. RESULTS: During the intervention period, most participants maintained their travel habits. In total, 91% of pupils maintained their travel mode to school. Only 6% of pupils switched to motorized travel and 3% switched to active travel, with small variations according to season and trip direction. The intervention did not seem to influence the likelihood of changing travel mode. The odds ratios for changing travel habits in spring/summer season were from active to motorized travel 1.19 [95%CI: 0.53-2.15] and changing from motorized to active travel 1.18 [0.30-2.62], compared to the "No change" group. These findings were consistent to and from school, and for the autumn/winter season. CONCLUSION: The extra school-based physical activity does not seem to affect rates of active travel among adolescents in the ScIM project. TRIAL REGISTRATION: Clinicaltrials.gov ID nr: NCT03817047.

AIMS: This cross-sectional study investigated the association between health-related quality of life (HRQoL), cardiorespiratory fitness (CRF) and muscular fitness in 14-year-old adolescents. METHODS: Norwegian adolescents (N = 1985) carried out a 10-min running test to assess cardiorespiratory fitness and three different muscular fitness tests (handgrip, sit-ups, and standing broad jump) and answered the KIDSCREEN-27 questionnaire to provide HRQoL data. Linear-mixed effect models were applied to detect relationships among the variables. RESULTS: Running-test results were positively associated with higher scores in the following KIDSCREEN domains: physical well-being, psychological well-being, autonomy and parent relationships, and school environment (ß = 0.01-0.04; p < .01 for all). Performance in sit-ups test was positively associated with higher scores in three out of five KIDSCREEN domains: physical well-being (ß = 0.31; p < .001), social support and peers (ß = 0.16; p = .023), and school environment scores (ß = 0.19; p = .006). An inverse association was found between the handgrip test results and the score on psychological well-being domain (ß = - 0.10; p = .013). CONCLUSIONS: The associations between HRQoL and physical fitness were trivial (abdominal strength and handgrip strength) to small (CRF) but confirmed that earlier findings from children also are applied to adolescents. Explosive strength in the lower body showed no association with HRQoL. Further research should investigate the direction of causality. TRIAL REGISTRATION: Clinicaltrials.gov ID nr: NCT03817047.

OBJECTIVES: To determine if subpopulations of students benefit equally from school-based physical activity interventions in terms of cardiorespiratory fitness and physical activity. To examine if physical activity intensity mediates improvements in cardiorespiratory fitness. DESIGN: Pooled analysis of individual participant data from controlled trials that assessed the impact of school-based physical activity interventions on cardiorespiratory fitness and device-measured physical activity. PARTICIPANTS: Data for 6621 children and adolescents aged 4-18 years from 20 trials were included. MAIN OUTCOME MEASURES: Peak oxygen consumption (VO2Peak mL/kg/min) and minutes of moderate and vigorous physical activity. RESULTS: Interventions modestly improved students' cardiorespiratory fitness by 0.47 mL/kg/min (95% CI 0.33 to 0.61), but the effects were not distributed equally across subpopulations. Girls and older students benefited less than boys and younger students, respectively. Students with lower levels of initial fitness, and those with higher levels of baseline physical activity benefitted more than those who were initially fitter and less active, respectively. Interventions had a modest positive effect on physical activity with approximately one additional minute per day of both moderate and vigorous physical activity. Changes in vigorous, but not moderate intensity, physical activity explained a small amount (~5%) of the intervention effect on cardiorespiratory fitness. CONCLUSIONS: Future interventions should include targeted strategies to address the needs of girls and older students. Interventions may also be improved by promoting more vigorous intensity physical activity. Interventions could mitigate declining youth cardiorespiratory fitness, increase physical activity and promote cardiovascular health if they can be delivered equitably and their effects sustained at the population level.
RESUMO
BACKGROUND: Physical activity (PA) declines throughout adolescence, therefore PA promotion during this period is important. We analyzed the effect of two school-based PA interventions on daily PA levels, cardiorespiratory fitness (CRF) and muscle strength among adolescents. METHODS: For the nine-month School in Motion intervention study (ScIM), we cluster-randomized 30 Norwegian secondary schools (N = 2084, mean age [SD] = 14 [0.3] years) to one of three study arms. The physically active learning (PAL) intervention included 30 min physically active learning, 30 min PA and a 60 min physical education (PE) lesson per week. The Don't worry-Be happy (DWBH) intervention included a 60 min PA lesson and a 60 min PE lesson per week, both tailored to promote friendships and wellbeing. Both intervention arms were designed to engage the adolescents in 120 min of PA per week in addition to recess and mandatory PE lessons. The control group continued as per usual, including the standard amount of mandatory PE. PA (main outcome) was assessed by accelerometers, CRF and muscle strength (secondary outcomes) were assessed by an intermittent running test and selected tests from the Eurofit test battery. RESULTS: Daily PA and time spent in moderate- to vigorous-intensity PA (MVPA) decreased in all groups throughout the intervention. The mean difference in PA level and MVPA for participants in the PAL-intervention arm was 34.7 cpm (95% CI: 4.1, 65.3) and 4.7 min/day (95% CI: 0.6, 8.8) higher, respectively, compared to the control arm. There were no significant intervention effects on daily PA level, MVPA or time spent sedentary for adolescents in the DWBH-intervention arm. Adolescents in the PAL-intervention arm increased distance covered in the running test compared to controls (19.8 m, 95% CI: 10.4, 29.1), whilst a negative intervention effect was observed among adolescents in the DWBH-intervention arm (- 11.6 m, 95% CI: - 22.0, - 1.1). CONCLUSION: The PAL-intervention resulted in a significantly smaller decrease in daily PA level, time spent in MVPA, and increased CRF compared to controls. Our results indicate that a teacher-led intervention, including three unique intervention components, is effective in curbing the decline in PA observed across our cohort and improving CRF.

BACKGROUND: Since the early 2000s, Healthy Life Centres have been established in Norway to promote physical and mental health. Yet to date, little is known about the efficacy of Healthy Life Centres in promoting health behaviour change and maintenance or the factors that underlie these processes. Accordingly, the aim of the current study was to examine the factors that participants in a Healthy Life Centre perceive as relevant for the initiation and maintenance of lifestyle changes toward more physical activity and consumption of a healthier diet. METHOD: Participants were purposely recruited from among adherers in a 12-month multi-method research project at a Healthy Life Centre. Individual, semi-structured interviews were conducted with 8 women and 6 men who were between the ages of 20 and 61 years old. Data were analysed using Systematic Text Condensation. RESULTS: Three main themes were derived from this analysis. The first theme focused on the motives behind initiation and maintenance of lifestyle changes along with the importance of a relationally supportive environment to promote perceived competence in pursuing a healthy lifestyle. The second theme focused on strategies for coping with the challenges and potential pitfalls that were associated with various unpleasant experiences and life events. The third theme focused on several specific skills that were helpful to the initiation and maintenance of lifestyle changes. CONCLUSION: The current study enhanced an understanding of the initiation and maintenance of lifestyle changes, although these processes were not disentangled in participants' experiences. In line with self-determination theory, the results suggested that lifestyle change is more likely to be initiated and maintained when goals are not only achievable but also regulated with autonomous motivation and of intrinsic value. Conversely, lifestyle change is difficult to maintain when motives are external to the self. Further, cognitive and behavioural skills were valuable and necessary in coping with unpleasant emotions. Finally, the critical function of self-regulation skills for making realistic plans and prioritizations in order to balance healthy lifestyle behaviours with the routines of "daily life" while monitoring outcomes was readily apparent. Healthy Life Centres can contribute to these processes in meaningful ways.

BACKGROUND: Studies indicate that health-related components of physical fitness are associated with mental health outcomes. However, research is scarce concerning this relationship in young adolescents in general and non-existent in Norwegian populations specifically. The aim of the study was to examine whether body composition, muscular strength and cardiorespiratory fitness were associated with self-reported mental health in Norwegian adolescents. METHODS: Adolescents from four regions of Norway (n = 1486; mean age = 13.9; girls = 50.6%) participated. Self-reported mental health (psychological difficulties) was measured by completing the Strengths and Difficulties Questionnaire. Cardiorespiratory fitness was assessed with an intermittent running test; muscular strength was assessed by measuring handgrip strength, standing broad jump and sit-ups; and body composition was assessed by calculating body mass index from weight and height. Linear mixed effects models were conducted to assess the associations between the health-related components of physical fitness and psychological difficulties. School clusters were included as random effects and all models were controlled for sex, socioeconomic status and birthplace (domestic or foreign). RESULTS: Body composition was not associated with psychological difficulties. Muscular strength was independently associated with psychological difficulties, but when all independent variables were entered in the fully adjusted model, only cardiorespiratory fitness was associated with psychological difficulties. CONCLUSIONS: There was a small but significant inverse association between cardiorespiratory fitness and levels of psychological difficulties in Norwegian adolescents. The results suggest that muscular strength is not associated with psychological difficulties in adolescents, when controlling for cardiorespiratory fitness. Future research should focus on the prospective association between physical fitness components and mental health outcomes in adolescents. TRIAL REGISTRATION: The study is registered in ClinicalTrials.gov ID nr: NCT03817047. Retrospectively registered January 25, 2019.

INTRODUCTION: Implementation of school-based physical activity (PA) programmes has proven to be difficult, particularly due to schools' focus on academic performance and lack of organisational support for PA interventions. However, physically active lessons (PA integrated into academic lessons) holds promise as a teaching method that increases children's PA levels without reducing academic time. Headteachers play a significant role in facilitating change in school, but little is known about headteachers' attitudes towards physically active lessons and their benefits. The purpose of this study was to explore headteachers' perceptions of physically active lessons, and identify factors affecting headteachers' acceptance or rejection of physically active lessons implementation. METHOD: A total of 29 semi-structured telephone interviews were conducted with headteachers in primary and secondary schools in the city of Stavanger, Norway. Adopting a phenomenological approach, qualitative data were analysed using inductive content analysis. RESULTS: Although most of the headteachers believed that physically active lessons could contribute positively to pupils' health and learning, only four of 29 schools decided to proceed with implementation. Physically active lessons were more likely to be adopted when the intervention addressed a clearly defined priority area at the school. Change overload and lack of in-depth knowledge of physically active lessons' function and intent appeared to be the most important factors for choosing not to implement physically active lessons. CONCLUSION: One of the major challenges for headteachers was deciding which of the many proposed changes the school should prioritise. If physically active lessons was to be prioritised by headteachers it is very important to communicate thoroughly to the headteachers what the schools can achieve by implementing physically active lessons and how the innovation aligns with school policies and goals. Given the flexibility inherent in physically active lessons and the schools' differing needs and priorities, it was important to emphasise to headteachers that physically active lessons could be adapted to different local school contexts.

BACKGROUND: To improve health and academic learning in schoolchildren, the Active School programme in Stavanger, Norway has introduced physically active academic lessons. This is a teaching method combining physical activity with academic content. The purpose of this paper was to evaluate the response to the physically active lessons and identify facilitators and barriers for implementation of such an intervention. METHODS: Five school leaders (principals or vice-principals), 13 teachers and 30 children from the five intervention schools were interviewed about their experiences with the 10-month intervention, which consisted of weekly minimum 2 × 45 minutes of physically active academic lessons, and the factors affecting its implementation. All interviews were transcribed and analysed using the qualitative data analysis program NVivo 10 (QSR international, London, UK). In addition, weekly teacher's intervention delivery logs were collected and analysed. RESULTS: On average, the physically active academic lessons in 18 of the 34 weeks (53%) were reported in the teacher logs. The number of delivered physically active academic lessons covered 73% of the schools' planned activity. Physically active lessons were well received among school leaders, teachers and children. The main facilitators for implementation of the physically active lessons were active leadership and teacher support, high self-efficacy regarding mastering the intervention, ease of organizing physically active lessons, inclusion of physically active lessons into the lesson curricula, and children's positive reception of the intervention. The main barriers were unclear expectations, lack of knowledge and time to plan the physiclly active lessons, and the length of the physically active lessons (15-20 min lessons were preferred over the 45 min lessons). CONCLUSION: Physically active academic lessons were considered an appropriate pedagogical method for creating positive variation, and were highly appreciated among both teachers and children. Both the principal and the teachers should be actively involved the implementation, which could be strengthened by including physical activity into the school's strategy. Barriers for implementing physically active lessons in schools could be lowered by increasing implementation clarity and introducing the teachers to high quality and easily organized lessons.

While physical activity during cancer treatment is found beneficial for breast cancer patients, evidence indicates ambiguous findings concerning effects of scheduled exercise programs on treatment-related symptoms. This study investigated effects of a scheduled home-based exercise intervention in breast cancer patients during adjuvant chemotherapy, on cancer-related fatigue, physical fitness, and activity level. Sixty-seven women were randomized to an exercise intervention group (n = 33, performed strength training 3x/week and 30 minutes brisk walking/day) and a control group (n = 34, performed their regular physical activity level). Data collection was performed at baseline, at completion of chemotherapy (Post1), and 6-month postchemotherapy (Post2). Exercise levels were slightly higher in the scheduled exercise group than in the control group. In both groups, cancer-related fatigue increased at Post1 but returned to baseline at Post2. Physical fitness and activity levels decreased at Post1 but were significantly improved at Post2. Significant differences between intervention and control groups were not found. The findings suggest that generally recommended physical activity levels are enough to relief cancer-related fatigue and restore physical capacity in breast cancer patients during adjuvant chemotherapy, although one cannot rule out that results reflect diminishing treatment side effects over time.

BACKGROUND: Substance use disorder is associated with unhealthy lifestyle choices, resulting in adverse social and health consequences. People with opioid use disorder receiving opioid agonist therapy, in particular, have high morbidity and reduced quality of life. Physical activity is recommended as an adjunctive treatment for people with substance use disorder, but there is minimal evidence from randomized controlled trials on the effects of this among people with substance use disorder receiving opioid agonist therapy. METHODS: BAReAktiv is a multicentre randomized controlled trial. The study aims to recruit 324 patients receiving opioid agonist therapy (parallel groups randomized 1:1 to integrated exercise intervention or control, superiority trial). A 16-week group-based integrated exercise intervention with workouts twice a week. The exercise program consists of endurance and resistance training. The target group will be patients 18 years and older receiving opioid agonist therapy in outpatient clinics in several centers in Western Norway. The primary outcome of the study is the effect on psychological distress measured by Hopkins' symptom checklist with ten items. Secondary outcome measures include physical functioning assessed with a 4-min step test, activity level, fatigue symptoms, quality of life, and changes in inflammation markers. This study will provide improved knowledge on the effects of an integrated exercise program in opioid agonist therapy. DISCUSSION: Systematically integrating exercise programs for people receiving opioid agonist therapy could lead to a shift towards a stronger focus on health behaviors in outpatient care. Integrating exercise could benefit patient recovery and reduce disease burden. Further scale-up will be considered if the provided exercise program is safe and effective.

AIMS AND OBJECTIVES: To examine research findings regarding predictors of adherence to exercise programmes in cancer populations. BACKGROUND: Cancer patients are advised to participate in daily exercise. Whether they comply with the recommendations for physical activity or not remains unclear. DESIGN: A systematic review and meta-analysis. METHODS: Empirical articles published in English between 1995 and 2011 were searched in electronic databases and in reference lists, using the search terms 'adherence', 'predictors', 'exercise', and 'cancer' in varying combinations. Twelve of 541 screened abstracts met the inclusion criteria. The included studies' eligibility considering predictors of exercise adherence were reviewed. A quality assessment process evaluating the studies methodological quality was performed. Eight of the reviewed studies were considered eligible for a meta-analysis involving Pearson's r correlations. RESULTS: Exercise stage of change, derived from the transtheoretical model of behaviour change (TTM) was found to be statistically significant and a strong predictor of exercise adherence. In addition, the theory of planned behaviour (TPB) construct; intention to engage in a health-changing behaviour and perceived behavioural control, demonstrated significant correlations with exercise adherence. CONCLUSIONS: The review identified that both the TPB and the TTM frameworks include aspects that predicts exercise adherence in cancer patients, and thus contributes to the understanding of motivational factors of change in exercise behaviour in cancer populations. However, the strengths of predictions were relatively weak. More research is needed to identify predictors of greater importance. RELEVANCE TO CLINICAL PRACTICE: Surveying the patients' readiness and intention to initiate and maintain exercise levels, as well as tailoring exercise programmes to individual needs may be important for nurses in order to help patients meet exercise guidelines and stay active.

Background: Use of physical activity in the treatment and follow-up of people receiving opioid substitution therapy is an understudied area of research. Therefore, the objective of this systematic review was to synthesize the currently available research on the role of physical activity in opioid substitution therapy and proper adaptions for the group. Methods: A systematic search was performed on PsycINFO, EMBASE, MEDLINE, CINAHL, and Web of Science until September 2021 (PROSPERO-reg.no: CRD42020109873). The inclusion criteria were studies involving physical activity interventions for opioid substitution patients. Reference lists of relevant studies were screened to identify additional relevant studies. Data extracted were compiled into tables and descriptively presented. Results: The search yielded 2105 unique records. A total of 10 studies were included, whose methodological quality ranged from satisfactory to very good. Study quality was assessed using a 7-/8-point quality score. The agreement between the reviewers, assessed with Cohen's kappa, was 0.91. Overall, the results suggest that physical activity increases physical fitness of patients in opioid substitution therapy and decreases substance use. The minority of studies in this field are of high quality with sufficient power. Conclusions: The findings of this systematic review suggest beneficial effects of physical activity on physical fitness, substance use, and mental health for patients in opioid substitution therapy. Although the findings are quite consistent across studies, high-quality studies and sufficiently powered clinical trials are needed to confirm and validate the findings and to conclude on the degree of impact.
RESUMO
Healthy Life Centers (HLCs) have been established throughout Norway to support lifestyle changes and promote physical and mental health. We conducted a 12-month observational study among participants in an HLC that aimed to improve physical activity (PA) and dietary behaviors, and this study examined predictors of completion, and changes in psychological variables, lifestyle behaviors, and physical health indicators. The participants (N = 120, 71% female, mean age = 44 years) reported symptoms of psychological distress (77%) and were obese (77%). No baseline characteristics were found to be consistent predictors of completion (42%). Completers had significant improvements in autonomous motivation for PA (d = 0.89), perceived competence for PA (d = 1.64) and diet (d = 0.66), psychological distress (d = 0.71), fruit intake (d = 0.64), vegetable intake (d = 0.38), BMI among all participants (d = 0.21) and obese participants (d = 0.34), body fat percentage among all participants (d = 0.22) and obese participants (d = 0.33), and lower body strength (d = 0.91). Fat-free mass and all forms of PA remained unchanged from baseline to 12 months. Hence, there were indications of improvement among completers on psychological variables, lifestyle behaviors, and physical health indicators. The low rate of completion was a concern, and the unchanged levels of PA reflect an important area of focus for future interventions in the context of HLCs.

BACKGROUND: The purpose of the study was to assess whether people could be motivated in a simple way to cycle regularly to and from work during one year, and to assess whether this could lead to any health-related physiological benefits. MATERIAL AND METHODS: 25 persons who cycled to and from work during one year were included in the study. Maximum oxygen uptake (VO2max) and body mass index (BMI) were measured at baseline, after six months and after one year. Total-cholesterol (TC) and HDL-cholesterol (HDL) were measured at the start and the end of the project. RESULTS: During the study VO 2max increased with 15.8 %; from 32.5 (8.1: SD) to 37.1 (7.6) ml x kg(-1) x min(-1) (p < 0.001). HDL-cholesterol increased with 15.3 %; from 1.31 (0.31) to 1.51 (0.40) mmol x l(-1) (p < 0.001). No changes were recorded for BMI. The numbers of cycling sessions were greatly reduced during the winter months because of poor cycling conditions. INTERPRETATION: This study shows that cycling to and from work may positively affect physiological variables and thereby have a beneficial health effect.

Combining physical activity and academic content is a promising way to improve health and academic learning in schoolchildren. This paper examined the continuation of physically active lessons (PAL) in five Norwegian elementary schools, two years after a 10-month intervention period, which consisted of weekly minimum 2 x 45 min of PAL. Data were collected through semi-structured interviews with nine teachers and five school leaders. The Level of Use instrument was used to assess how the teachers integrated PAL into the school day. Two years after the intervention period, seven of nine teachers conducted PAL regularly, on average one lesson per week. Teachers' implementation progress varied from struggling with logistics, to stable routine and creative adaption. Perceived benefits for the children, active leadership, and ongoing implementation support seem important for continuation. Introduction of PAL as a school development project, systematic planning from the onset and a gradual introduction of PAL, can be an effective strategy for continuation and long-term sustainability. In addition, the Level of Use instrument was useful to better understand which support mechanisms are needed at different stages in the implementation of PAL.

BACKGROUND: This cross-sectional study investigated whether the relationship between aerobic fitness and academic performance was mediated by executive functioning. METHODS: A total of 378 children (9-10 years old) from nine primary schools in Stavanger, Norway were included. The children's aerobic fitness was measured by a 10-minute interval-running test; executive function was tested by four cognitive tests (Stroop, Trail Making, Verbal Fluency and Backwards Digit Span). A composite score for executive functions was computed and used in analyses. Academic achievement in reading, mathematics and English was determined using Norwegian national standardized tests. RESULTS: Bivariate correlation analysis showed the following significant associations: mathematic achievement with executive functions (r=0.48, P=0.001), aerobic fitness with mathematics (r=0.13, P=0.012) and executive functions (r=0.17, P=0.001). A regression-based mediation analysis (PROCESS) with executive function as a mediator variable was conducted. Mediation analysis showed that the relationship between aerobic fitness and mathematic achievement was mediated by executive functions (P<0.001). CONCLUSIONS: Findings revealed an indirect effect of executive function on the positive relationship between aerobic fitness and mathematic achievement.

PURPOSE: This study's purpose was to examine whether established risk categories of waist circumference (WC)-normal, high risk, and very high health risk-reflected significant differences in cardiorespiratory fitness (CRF) and physical activity (PA) level. METHODS: CRF was directly measured as maximal oxygen uptake during a progressive graded treadmill test to exhaustion in 722 individuals (349 women) aged 20-85 years. WC was measured between the lower rib and the iliac crest. Objectively measured PA was assessed using an accelerometer. RESULTS: Men in the normal risk group (WC < 94 cm) had a 31% higher CRF and 43% higher level of moderate-to-vigorous PA than men in the very high risk group (with a WC > 102 cm). Corresponding numbers for women within normal (WC < 80 cm) and very high risk group (WC > 88 cm) were 25% and 18% (p < 0.05). There was a high negative correlation between CRF and WC in men (r = -0.68), and a moderate correlation for women (r = -0.49; p < 0.001). For each cm increase in WC, CRF was reduced by 0.48 and 0.27 mL/kg/min in men and women, respectively (p < 0.001). CONCLUSION: The recommended WC thresholds for abdominal obesity reflected significant differences in CRF for both men and women, and could serve as a useful instrument for estimating health-related differences in CRF.
RESUMO
The Active School program was designed to positively impact health and academic-related outcomes in school. The core intervention component was physically active academic lessons, a teaching activity that combines physical activity and educational content. The purpose of this study was to investigate the effect of a 10-month, cluster-randomized controlled trial on physical activity level and aerobic fitness conducted in the city of Stavanger, Norway, in 2014-15. The physical activity level during physically active academic lessons was also studied. A total of 447 children (9-10â¯years) participated. The weekly intervention consisted of physically active academic lessons, physically active homework and physically active recess. Physical activity level and aerobic fitness were measured objectively by accelerometry and a 10-minute interval running test. Intervention effects were found for time in moderate to vigorous physical activity (MVPA) (adjusted mean difference of 8â¯min/day, 95% CI: 3.4-13, pâ¯<â¯0.001) and total physical activity (60â¯counts/min, 95% CI: 15-105, pâ¯=â¯0.009). Children with low aerobic fitness increased their running distance compared to controls (dâ¯=â¯0.46; pâ¯=â¯0.001). During physically active academic lessons children spent 26% of the time in MVPA, which was comparable to physical education lessons. The Active School program successfully increased physical activity for the intervention group and aerobic fitness for the least fit children. The activity level during physically active academic lessons was as high as in physical education lessons. Clinicaltrail.gov ID identifier: NCT03436355.
RESUMO
PURPOSE: The goal was to register physical training volume and to measure changes in physical fitness in soldiers during a peacekeeping mission. The relationship between these factors and motivation for physical training was also investigated. METHODS: Physical training volume was registered and maximal oxygen uptake, 3-km run time, sit-ups, push-ups, and chin-ups were tested before and after 1 year of service for 71 Norwegian soldiers in the international Kosovo Force. Self-determined motivation was measured at the end of the service. RESULTS: Physical training volume was 117 +/- 77 minutes/week. The average maximal oxygen uptake decreased by 2.5 +/- 0.8% (p < 0.01). Intrinsic motivation positively predicted physical training volume (p < 0.01). CONCLUSIONS: A large variation in training volume was found, and only one-third of the soldiers improved physical fitness and maintained body weight. Fostering intrinsic motivation toward physical training is key to increasing training volume. However, obligatory training could ensure a minimum of physical training among the soldiers who were least motivated for physical training.

OBJECTIVE: Evaluate the physical fitness and training of Norwegian infantry soldiers during 10 months of compulsory military service. METHODS: Maximal oxygen uptake (VO2max) and maximal numbers of sit-ups, push-ups, and chin-ups and 3-km running time were tested in 107 male infantry soldiers at the beginning and end of basic training (BT), and again at demobilization. The amount of physical training was registered throughout the military service. RESULTS: During BT, major improvements in sit-ups and push-ups were found. VO2max increased in soldiers with the lowest initial VO2max, but decreased to pre-BT level at demobilization. The amount of obligatory physical training was 8.5 hours x week(-1) during BT and 35% lower after BT, and was usually performed in uniform at low to moderate intensity. CONCLUSION: The amount of high-intensity endurance and strength training during compulsory military service is to low to improve the soldiers' endurance and muscular strength.
