2. 1. Physiology of Adventure Racing : with emphasis on circulatory response and cardiac fatigue

   Author : C. Mikael Mattsson; Björn Ekblom; Keith P George; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiovascular drift; cardiac fatigue; adventure race; cardiac biomarkers; cardoac function; exercise echocardiography; Physiology; Fysiologi; Cardiology; Kardiologi; Sports; Idrott; Medicin Teknik; Medicine Technology;

   Abstract : The overall aims of this thesis were to elucidate the circulatory responses to ultra-endurance exercise (Adventure Racing), and furthermore, to contribute to the clarification of the so called “exercise-induced cardiac fatigue” in relation to said exercise. An Adventure race (AR) varies in duration from six hours to over six days, in which the participants have to navigate through a number of check-points over a pre-set course, using a combination of three or more endurance/outdoor sports, e.

4. 2. Mitochondrial function in human skeletal muscle: with special reference to exercise and training

   Author : Michail Tonkonogi; Högskolan Dalarna; Karolinska Institutet; Karolinska Institutet; []
   Keywords : aerobic metabolism; oxidative phosphorylation; mitochondria; oxygen utilisation; citrate synthase; ADP sensitivity; ATP; muscle fibres; hydrogen ions; lactate; free radicals; proton leak; uncoupling; exercise; aerobic metabolism; oxidative phosphorylation; mitochondria; oxygen utilisation; citrate synthase; ADP sensitivity; ATP; muscle fibres; hydrogen ions; lactate; free radicals; proton leak; uncoupling; exercise;

   Abstract : The overall objective of this thesis was to study the adaptation of oxidative function in human skeletal muscle to acute exercise of different modes, intensities and durations, and to endurance training. The effects of endurance training on mitochondrial function were evaluated in cross-sectional and longitudinal studies by measurements of mitochondrial oxygen consumption in isolated mitochondria and permeabilised muscle fibres and measurements of mitochondrial ATP production rate in isolated mitochondria.

5. 3. The role of exercise and exercise-related factors in the control of mitochondrial oxidative function

   Author : Brandon Walsh; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Skinned fibers; permeabilized fibers; skeletal muscle; exercise; mitochondria; ADP sensitivity; aerobic metabolism; training; eccentric; high intensity; creatine; phosphocreatine; inorganic phosphate; hydrogen ions;

   Abstract : The effects of exercise and exercise-related factors on the control of mitochondrial oxidative function were investigated in human and rat skeletal muscle. Oxidative function was assessed through the measurement of oxygen consumption in chemically permeabilized (skinned) fibers. READ MORE

6. 4. Skeletal muscle metabolism in patients with severe chronic obstructive pulmonary disease : A study of carbohydrate and fat metabolism

   Author : Per Jacobsson; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : In chronic obstructive pulmonary disease (COPD) deterioration of skeletal muscle metabolism is reported in both respiratory and non-respiratory muscles. This deterioration may contribute to both the development of respiratory failure and general disability often seen in severe COPD patients. READ MORE

7. 5. Human muscle response to sprint exercise in a gender perspective

   Author : Mona Esbjörnsson Liljedahl; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Anaerobic; Performance; Wingate-test; muscle biopsy; Adenine nucleotides; hormones; glycogen; type I fibres; type II fibres; fast twitch; slow twitch; muscle morphology; men; women; sprint training;

   Abstract : Anaerobic performance, muscle characteristics and acute and chronic response to sprint exercise were studied in physically active healthy women (n=35; age 24) and men (n=38; age 25). The aims of the present study were to: 1) Establish if women possess lower oxidative and glycolytic capacity, higher proportion of type I fibres and smaller type II fibre areas in relation to type I fibre areas in thigh musculature than men.
