1. 11. Cardiopulmonary Function in Healthy Individuals and in Patients After Hematopoietic Cell Transplantation

   Författare :Margareta Genberg; Andrei Malinovschi; Eva Nylander; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hematopoietic stem cell transplantation; echocardiography; cardiopulmonary execise testing; stress testing; onchology; childhood leukemia; healthy adults; breathing reserve; oxygen uptake; Clinical Physiology; Klinisk fysiologi;

   Sammanfattning : Background: The cardiopulmonary exercise test (CPET) is the gold standard of clinical exercise tests, combining conventional stress testing with measurement of oxygen uptake and carbon dioxide production. In order to interpret CPET findings, adequate reference values are needed. Currently, no Swedish reference values exist. LÄS MER

3. 12. Roller skis' rolling resistance and grip characteristics : influences on physiological and performance measures in cross-country skiers

   Författare :Mats Ainegren; Peter Carlsson; Marko Laaksonen; Mittuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adjustable grip; blood lactate; centre of pressure; cycle length; cycle rate; economy; efficiency; friction coefficient; heart rate; normal force; OBLA; oxygen uptake; power; ratcheted wheel; ratings of perceived exertion; roller skis; rolling resistance; tangential force; time to exhaustion;

   Sammanfattning : The aim of this thesis was to investigate roller ski characteristics; classical and freestyle roller skis’ rolling resistance coefficients (μR) and classical style roller skis’ static friction coefficients (μS), and to study the influence of different μR and μS on cross-country skiers’ performance and both physiological and biomechanical indices. The aim was also to study differences in skiing economy and efficiency between recreational skiers, female and male junior and senior elite cross-country skiers. LÄS MER

4. 13. Physical Fitness and Pregnancy

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical fitness; oxygen uptake; pregnancy; back pain; blood pressure; duration of gestation; relaxin; cycle ergometer test; physical exercise; perceived health;

   Sammanfattning : Objectives To assess physical fitness in pregnancy and to evaluate its effect on perceived health, back pain, blood pressure and duration of gestation. Also, to evaluate the effect of serum relaxin levels on blood pressure and duration of gestation. LÄS MER

5. 14. The rolling resistances of roller skis and their effects on human performance during treadmill roller skiing

   Författare :Mats Ainegren; Peter Carlsson; Marko Laaksonen; Per Tesch; Mittuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood lactate; cycle length; cycle rate; heart rate; oxygen uptake; performance; power; roller skis; rolling resistance; ratings of perceived exertion; work economy; Sports; Idrott;

   Sammanfattning : Modern ski-treadmills allow cross-country skiers, biathletes and ski-orienteers to test their physical performance in a laboratory environment using classical and freestyle techniques on roller skis. For elite athletes the differences in performance between test occasions are quite small, thus emphasising the importance of knowing the roller skis’ rolling resistance coefficient, µR, in order to allow correct comparisons between the results, as well as providing the opportunity to study work economy between different athletes, test occasions and core techniques.

7. 15. Exercise in patients with chronic heart failure. With emphasis on peripheral muscle training, hydrotherapy and type 2 diabetes mellitus

   Författare :Åsa Cider; Göteborgs universitet; []
   Nyckelord :Exercise tolerance; Ejection fraction; Metabolic function; Muscle function; Oxygen uptake; Physical therapy techniques; Quality of life; Rehabilitation; Stroke volume; Water immersion;

   Sammanfattning : Chronic heart failure (CHF) is not uncommon in developed countries with a growing ageing population. CHF is a chronic syndrome, which markedly impact negatively on the patient s life situation. Considerable impaired physical function and reduced health related quality of life is often present.
