1. 16. Muscle function and physical activity in pre-pubertal school children

   Författare :Susanna Stenevi Lundgren; Ortopedi - klinisk och molekylär osteoporosforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; children; physical activity; exercise; isokinetic muscle strength; vertical jump height; normative; intervention; school transport; DXA; anthropometry; fat mass; lean mass; weight; height; body mass index; girls; boys; pre-pubertal;

   Sammanfattning : Background: Regular participation in physical activity or organized exercise is regarded as one important lifestyle factor that could improve musculoskeletal health, fitness and body composition. For children and adolescents physical activity is important not only in training of the neuromuscular system, coordination and balance, but in a wider perspective, for adopting a lifestyle that possibly reduces the risk of coronary artery disease, obesity, osteoporosis and other contributors to morbidity and mortality in the population.

   Sammanfattning : Objective: To investigate the role of magnetic resonance imaging (MRI), assessment of bone mineral density (BMD) and antibodies to citrullinated proteins (anti-CCP) in predicting radiologic outcome in patients with early rheumatoid arthritis (RA). Patients: All patients were included in the BARFOT programme (baseline). LÄS MER

4. 18. Femoral Strength Prediction using Finite Element Models : Validation of models based on CT and reconstructed DXA images against full-field strain measurements

   Sammanfattning : Osteoporosis is defined as low bone density, and results in a markedly increased risk of skeletal fractures. It has been estimated that about 40% of all women above 50 years old will suffer from an osteoporotic fracture leading to hospitalization. LÄS MER

   Sammanfattning : Introduction: Thanks to achievements in paediatric heart surgery and medicine, the population of adults with surgically repaired or palliated congenital heart defects is growing. Many of these adults have reduced exercise capacity, weaker muscular strength and shorter height, all of which suggest an altered body composition. LÄS MER

7. 20. Skeletal growth and effects of physical activity during adolescence

   Sammanfattning : The aim of this thesis was to evaluate bone mass and bone size in girls and boys from age 12 to 16, with special attention to physical activity. We also wanted to retrospectively evaluate the effect of exercise for the years preceding age 12. The findings were as follows. LÄS MER
