1. 1. Effect of Physical Activity on Bone, Muscle and Fracture Risk during Growth

   Författare :Bjarne Löfgren; Ortopedi - klinisk och molekylär osteoporosforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; BMC; bone size; children; exercise; fracture; growth; hip stucture analysis; muscle strength; physical activity;

   Sammanfattning : Osteoporosis and related fractures are a global health problem. Physical activity, especially during growth, has been suggested as a strategy to improve musculoskeletal health in the population. LÄS MER

3. 2. 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.

4. 3. Physical activity and the young female skeleton

   Författare :Örnolfur Valdimarsson; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; muskelsystem; reumatologi; Skelett; Skeleton; muscle system; rheumatology locomotion; Bone mass; Osteoporosis; Young female skeleton; Physical activity;

   Sammanfattning : The aim of this thesis was to identify the influence of calcium, physical activity and detraining on bone mass and bone size in girls and young women. We hypothesised that calcium intake above a specific level does not enhance the accrual of bone mineral, that exercise predominantly influences the skeleton in the early pubertal period and that reduced training is followed by a loss of exercise-induced skeletal benefits.

5. 4. The Influence of Physical Activity on Musculoskeletal Characteristics and Fracture Risk at Growth

   Författare :Fredrik Detter; Ortopedi - klinisk och molekylär osteoporosforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; BMC; BMD; pQCT; DXA; Fractures; Children; Bone; Muscle;

   Sammanfattning : Physical Activity (PA) can improve neuromuscular development. A high level of physical activity can perhaps however lead to more fractures. This is a longitudinal population-based exercise intervention study where the school-based physical education (PE) in one school is increased from mean 60 min/week to mean 200 min/ week. LÄS MER

7. 5. Stress in chickens : Effects of domestication and early experience on behaviour and welfare

   Författare :Maria Ericsson; Per Jensen; Linda Keeling; Bjarne Braastad; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The domestication is the process where animals have adapted to human conditions. A prerequisite for domestication is tame behaviour towards humans and subsequently, selection for other desirable traits took place which led to changes in several behavioural and physiological parameters.
