1. The heart rate method for estimating oxygen uptake in walking and cycle commuting : Evaluations based on reproducibility and validity studies of the heart rate method and a portable metabolic system
Abstract : Walking and cycling to work can contribute to population health, but more objective knowledge concerning exercise intensities, oxygen uptake and the metabolic demands of this physical activity is needed for this and other evaluations. To attain this, valid and reliable instruments are a requirement. READ MORE

2. Roller skis' rolling resistance and grip characteristics : influences on physiological and performance measures in cross-country skiers
Abstract : 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. READ MORE

3. The rolling resistances of roller skis and their effects on human performance during treadmill roller skiing
Abstract : 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.

4. Assessment of Aerobic Capacity A Novel Rating Scale and Further Development of an Exercise Test including Analysis of Gas Exchange
Abstract : Different methods are proposed to assess the aerobic capacity. A novel scale, rating of perceived capacity (RPC) based on metabolic equivalents (METs) from 1 to 20, is presented. Selected MET values are linked to physical activities. READ MORE

5. The significance of mitochondrial respiratory function in regulating oxygen uptake and performance in humans
Abstract : The mitochondrion is one of the most fascinating organelles of our cells which has kept and keeps researchers busy in studying its origin, the complex morphology, the numerous functions, the rapid adaptations to a variety of stimuli and its role in health and disease. Exercise challenges cellular homeostasis and skeletal muscle mitochondria greatly adapt to repeated bouts of exercise by increasing mitochondrial respiratory function and content to match energy requirements and to better sustain future perturbations induced by muscle contractions.
