1. Effects of unloading and resistance exercise on skeletal muscle function, size and composition in man
Sammanfattning : Exposure to microgravity, i.e., spaceflight, causes muscle unloading leading to muscle atrophy and dysfunction. Thus, there is a need for effective countermeasures to combat these effects. LÄS MER
2. Ankle fractures. Outcome and rehabilitation. A physiotherapeutic perspective
Sammanfattning : The overall aim of this work was to evaluate symptoms, subjectively scored function and physical outcome in patients with surgically treated ankle fractures. Another aim was also to evaluate the effects of a standardised but individually suited supervised training program. LÄS MER
3. On spinal mechanisms for reflex control in man : modulation of Ia-afferent excitation with changes in muscle length, activation level and fatigue
Sammanfattning : To control muscle force, neural activation has to take alterations in muscle mechanics into account. This thesis assesses modulations in excitatory efficacy of Ia-afferents during muscle length changes at different levels of voluntary activation and during fatigue. LÄS MER
4. Elite sprinters, ice hockey players, orienteers and marathon runners : isokinetic leg muscle performance in relation to muscle structure and training
Sammanfattning : In male athletes from different sports, isokinetic knee extensor, and in orienteers also plantar flexor peak torque (PT), contractional work (CW) and integrated surface electromyograms (iEMG) were analysed.Single contraction PT, CW and iEMG in sprinters and marathon runners were significantly correlated to the cross-sectional area (CSA) of m.

5. Evaluation of surface electromyography and aspects of muscle strength in persons without motor impairment and in children with hemiplegic cerebral palsy
Sammanfattning : Impaired muscle function significantly affects persons with Cerebral Palsy (CP), affects that include muscle strength, fatigue and endurance. This thesis evaluates a test method, an endurance test, and estimates aspects of muscle fatigue and muscle endurance in persons without impaired muscle function and in children with CP. LÄS MER
