The prevalence of disordered eating and eating disorders vary from 0-19% in male athletes and 6-45% in female athletes. The objective of this paper is to present an overview of eating disorders in adolescent and adult athletes including: (1) prevalence data; (2) suggested sport- and gender-specific risk factors and (3) importance of early detection,(More)
OBJECTIVE To examine the prevalence of dieting, reasons for dieting and prevalence of disordered eating among adolescent elite athletes and age-matched controls, and to examine the differences between athletes competing in leanness and non-leanness sports. METHODS First-year students of 16 different Norwegian Elite Sport High Schools (athlete group, n =(More)
AIMS Controversies exist on the role of physical activity on urinary incontinence (UI), and search on PubMed revealed no studies on UI in fitness instructors. The aim of this study was to investigate the prevalence of UI among female group fitness instructors, including Pilates and yoga teachers. METHODS This was a cross-sectional study of 1,473(More)
PURPOSE The aim of this study was to examine symptoms of eating disorders (ED), drive for muscularity and physical activity in a Norwegian adolescent population. METHODS A total of 722 adolescents aged 12-18 years (response rate: 83%) filled out a questionnaire containing the Drive for Muscularity Scale, Eating Disorders Inventory subscales Drive for(More)
OBJECTIVE To examine self reported versus objectively assessed moderate-to-vigorous physical activity (MVPA), and different reasons for exercise, in patients with longstanding eating disorders (ED) when compared with controls. METHOD Inpatient females (n = 59, mean 30.1 years) and nonclinical age matched controls (n = 53, mean 31.3 years) accepted(More)
OBJECTIVE To describe changes in physical activity (PA) and exercise dependence score during treatment of eating disorders (ED), and to explore correlations among changes in PA, exercise motivation, exercise dependence score and ED psychopathology in excessive and non-excessive exercisers. METHOD Thirty-eight adult females receiving inpatient treatment(More)
OBJECTIVE To examine associations among exercise dependence score, amount of physical activity and eating disorder (ED) symptoms in patients with longstanding ED and non-clinical controls. METHODS Adult female inpatients (n = 59) and 53 age-matched controls participated in this cross sectional study. Assessments included the eating disorders examination,(More)
Indirect calorimetry is a common and noninvasive method to estimate rate of fat oxidation (FatOx) during exercise, and test-retest reliability should be considered when interpreting results. Diet also has an impact on FatOx. The aim of the present study was to investigate day to day variations in FatOx during moderate exercise given the same diet and 2(More)
It remains to be established how high-intensity aerobic interval training (HAIT) affects risk factors associated with type 2 diabetes (TD2). This study investigated effects of HAIT on maximal oxygen uptake (VO2max), glycated Hemoglobin type A1C (HbA1c), insulin resistance (IR), fat oxidation (FatOx), body weight (BW), percent body fat (%BF), lactate(More)
PURPOSE High-intensity interval training (HIIT) is documented to yield effective improvements in the cardiovascular system and be an excellent strategy for healthy aging. However, it is not determined how age may affect the training response of key components of aerobic endurance. METHODS We recruited 72 males (mean ± SD, weight = 84.9 ± 12.9 kg, height =(More)
