Effects of a school-based physical activity intervention on academic performance in 14-year old adolescents: a cluster randomized controlled trial – …
2021
Abstract Background School-based physical activity interventions evaluating the effect on academic performance usually includes children. We aimed to investigate the effect of a nine-month, school-based physical activity intervention titled School in Motion (ScIM) on academic performance in adolescents. Methods Thirty secondary schools in Norway were cluster-randomized into three groups: the Physically active learning (PAL) group (n = 10), the Don’t worry – Be Happy (DWBH) group (n = 10) or control (n = 10). Target dose in both intervention groups was 120 min/week of additional PA during school hours. Parental consent was obtained from 2084 adolescent students (76%). Standardized national t…
Associations between parenting and substance use, meal pattern and food choices: A cross-sectional survey of 13,269 Norwegian adolescents
2019
Identifying factors that affect adolescent lifestyle behaviors is essential in order to develop effective generic prevention approaches. This study aimed to investigate the association between parental monitoring, parental emotional support, parental-adolescent conflict and adolescent substance use, meal pattern and food choices. The study included data from 13,269 Norwegian adolescents aged 13–16 years collected in 2016. Multivariable logistic regression models adjusted for gender, age and parental education were applied. Results show that low parental monitoring was associated with increased substance use (Odds ratios (OR) ranging from 2.8; 95% Confidence intervals (CI) 2.1–3.6 to OR 3.8;…
Elite athletes get pregnant, have healthy babies and return to sport early postpartum
2019
ObjectivesTo enhance knowledge on pregnancy and return to sport in the postpartum period in elite female athletes.Methods34 Norwegian elite athletes (33.1 years) and 34 active controls (31.5 years) were asked about training and competitive history, pregnancy-related issues, injuries, body dissatisfaction (BD), drive for thinness (DT), eating disorders (ED) and practical experiences, through a questionnaire and interview. Independent samples T-tests or χ² tests for between-group differences and paired-samples T-tests and repeated measures analysis of variance for within group differences were used.ResultsNo group differences in fertility problems, miscarriage, preterm birth or low birth weig…
Criterion validity of two physical activity and one sedentary time questionnaire against accelerometry in a large cohort of adults and older adults
2020
ObjectivesWe compared the ability of physical activity and sitting time questionnaires (PAQ) for ranking individuals versus continuous volume calculations (physical activity level (PAL), metabolic equivalents of task (MET), sitting hours) against accelerometry measured physical activity as our criterion.MethodsParticipants in a cohort from the Tromsø Study completed three questionnaires; (1) The Saltin-Grimby Physical Activity Level Scale (SGPALS) (n=4040); (2) The Physical Activity Frequency, Intensity and Duration (PAFID) questionnaire (n=5902)) calculated as MET-hours·week-1 and (3) The International Physical Activity questionnaire (IPAQ) short-form sitting question (n=4896). We validate…
The Phys-Can observational study: adjuvant chemotherapy is associated with a reduction whereas physical activity level before start of treatment is a…
2020
AbstractBackgroundAdjuvant therapy may cause multiple sideeffects on long term health, including reduced cardiorespiratory fitness (CRF) in patients with breast cancer (1, 2). However, there is currently limited knowledge regarding the effect of different types of adjuvant cancer treatment on CRF in other cancer populations. The primary objective of the present study was to assess whether previously known correlates (age, diagnosis, initial CRF, physical activity level), type of adjuvant treatment and cancer-related fatigue were associated with changes in$$ \dot{V}{O}_2\mathit{\max} $$V̇O2maxin patients with breast, prostate or colorectal cancer.MethodsProspective study with two time points…
Physical Activity Level Following Resistance Training in Community-Dwelling Older Adults Receiving Home Care: Results from a Cluster-Randomized Contr…
2021
Older adults’ physical activity (PA) is low. We examined whether eight months of resistance training increased PA level in community-dwelling older adults receiving home care. A two-armed cluster-randomized trial using parallel groups was conducted. The included participants were >
Psychosocial Risk Factors for Overuse Injuries in Competitive Athletes: A Mixed-Studies Systematic Review
2021
Abstract Background While the psychosocial risk factors for traumatic injuries have been comprehensively investigated, less is known about psychosocial factors predisposing athletes to overuse injuries. Objective The aim of this review was to systematically identify studies and synthesise data that examined psychosocial risk factors for overuse injuries in athletes. Design Systematic review. Data Sources MEDLINE, Web of Science and PsycINFO databases, supplemented by hand searching of journals and reference lists. Eligibility Criteria for Selecting Studies Quantitative and qualitative studies involving competitive athletes, published prior to July 2021, and reporting the relationship betwee…

Do Obese Children Achieve Maximal Heart Rate during Treadmill Running?
2019
Objective: Maximal heart rate (HR) is commonly defined as the highest HR obtained during a progressive exercise test to exhaustion. Maximal HR is considered one of the criteria to assess maximum exertion in exercise tests, and is broadly used when prescribing exercise intensity. The aim of the present study was to compare peak HR measurements during maximal treadmill running and active play in obese children and adolescents. Design: Comparison of peak heart rate during active play vs. maximal treadmill running in 39 (7&ndash
Effect of Sex, Body Mass Index and Physical Activity Level on Peak Oxygen Uptake Among 14–19 Years Old Adolescents
2020
The aim was to describe longitudinal trends in peak oxygen uptake (VO2peak) among 14- to 19-year-old adolescents in Norway, and to examine effects of sex, body mass index (BMI), and physical activity (PA) level on VO2peak during adolescence. Of 124 invited students from two lower secondary schools in Norway, 116 eighth-grade students (61 boys and 55 girls; 14 years old at baseline) volunteered to participate. The study has a longitudinal design with 6 yearly repeated measures of body height and mass, VO2peak and PA level. VO2peak allometrically scaled to body mass raised to the power of 0.67 was measured using a walking or running incremental test on a treadmill, whereas PA level was self-r…
