Har kroppsøvingsundervisningen noen langtidseffekt på helsen?: et kommenterende sammendrag av en forskningsartikkel fra Canada

Artikkelen er et sammendrag av en oversiktsartikkel i Sports Medicine 2008; 38 (4): 266-270, "Is there a Long-Term Health Legacy of Required Physical Education?" av François Trudeau og Roy J. Shephard. Det er lite forskning på området, lærere med utdannelse i kroppsøving ser ut til å lage timer som gir bedre treningseffekt enn det vanlige lærere gjør. En økning av timetallet i kroppsøving ser ikke ut til å påvirke prestasjonen i teorifag negativt

Increase in peak oxygen uptake and Andersen test performance in children from age six to ten: The Health Oriented Pedagogical Project (HOPP)

The increased prevalence of non-communicable disease risk factors among children because of lack of physical activity is concerning. The Health Oriented Pedagogical Project was set up to combine learning activities and physical activity, thus reducing sedentariness during school time. The current study aimed to measure and describe the longitudinal and cross-sectional development of oxygen uptake and running performance in children at ages six and ten. The validity of the Andersen Test in predicting V̇O2peak in these age groups was also evaluated. Eighty-six children (53 boys, 33 girls) with complete datasets at ages 6 and 10 years were included in the longitudinal study, while 192 children (106 boys, 86 girls) were included in the cross-sectional analysis because they missed data from 1 year. Oxygen uptake was measured using a metabolic analyser and maximal treadmill running, while the distance covered during the AT determined running performance. Body mass, height, and waist-to-height ratios were recorded. Multiple regression analysis was used to assess the association between oxygen uptake and running performance. The cross-sectional results did not differ from the longitudinal data for anthropometrical data, oxygen uptake and running performance. Height, body mass and waist-to-height ratio did not differ between the sexes at ages six or ten. Boys had significantly higher peak oxygen uptake than girls at 6 years of age, irrespective of how oxygen uptake was expressed. Allometric scaling of oxygen uptake revealed differences between sexes at both ages. Longitudinal running performance increased in both sexes from 6 to 10 years. Boys ran significantly longer only at age ten. The association between oxygen uptake and running performance varied according to how the oxygen uptake was expressed and with sex and age. Ten-year-old girls had the highest correlations in the longitudinal investigation, from r 2 = 0.48 (fV̇O2peak) to 0.65 (rV̇O2peak) between AT and V̇O2peak. The AT was found to be as valid as the 20-m shuttle run test in estimating peak oxygen uptake, with a random measurement error of approximately 11% of mean values.publishedVersio

A holistic perspective on continuing care for substance use and dependence: Results and implications from an in-depth study of a Norwegian continuing care establishment

This article explores, systematically and in depth, users’ perceptions of participating in a Norwegian non-profit establishment that provides a continuing care programme for substance use and dependence. Identified results are linked to a holistic system perspective, where human, technology, and organisation (HTO), as well as external environment, are viewed as intertwined. At the establishment level, i.e., where the continuing care programme is delivered, we find that a clear holistic and user-oriented profile – comprising combined interventions including physical and social activities – can create a safe and stable environment that exerts a positive mental and physical influence on the user and thereby promotes abstinence from substances. However, our results suggest that the internal environment needs to connect more strongly with the external environment, such as a substance-free network, close family, and working life. At the establishment level, we conclude that there is a need to develop an explicit strategy and practice for collaborating with the external environment, built on systemisation and application of individual users’ insights into the design of the current interventions. Further research should explore the presence and absence of interplays between elements of human, technology, and organisation and the external environment, and the associated consequences for intervention processes and users’ health outcomes. Our holistic system model, empirically informed by data from a Norwegian context, can represent a starting point for such endeavours. The holistic system model also constitutes an original and novel contribution to research on continuing care interventions.publishedVersio

The Role of Physical Activity in Opioid Substitution Therapy: A Systematic Review of Interventional and Observational Studies

ABSTRACT 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. keywORdS: Opioid maintenance treatment, exercise, medication-assisted treatmentpublishedVersio

Blood Pressure Response and Pulse Arrival Time During Exercise Testing in Well-Trained Individuals

Introduction: There is a lack of data describing the blood pressure response (BPR) in well-trained individuals. In addition, continuous bio-signal measurements are increasingly investigated to overcome the limitations of intermittent cuff-based BP measurements during exercise testing. Thus, the present study aimed to assess the BPR in well-trained individuals during a cycle ergometer test with a particular focus on the systolic BP (SBP) and to investigate pulse arrival time (PAT) as a continuous surrogate for SBP during exercise testing. Materials and Methods: Eighteen well-trained male cyclists were included (32.4 ± 9.4 years; maximal oxygen uptake 63 ± 10 ml/min/kg) and performed a stepwise lactate threshold test with 5-minute stages, followed by a continuous test to voluntary exhaustion with 1-min increments when cycling on an ergometer. BP was measured with a standard automated exercise BP cuff. PAT was measured continuously with a noninvasive physiological measurements device (IsenseU) and metabolic consumption was measured continuously during both tests. Results: At lactate threshold (281 ± 56 W) and maximal intensity test (403 ± 61 W), SBP increased from resting values of 136 ± 9 mmHg to maximal values of 219 ± 21 mmHg and 231 ± 18 mmHg, respectively. Linear within-participant regression lines between PAT and SBP showed a mean r 2 of 0.81 ± 17. Conclusion: In the present study focusing on the BPR in well-trained individuals, we observed a more exaggerated systolic BPR than in comparable recent studies. Future research should follow up on these findings to clarify the clinical implications of the high BPR in well-trained individuals. In addition, PAT showed strong intra-individual associations, indicating potential use as a surrogate SBP measurement during exercise testing.publishedVersio
