1. Identification of single motor units in ultrafast ultrasound image sequences of voluntary skeletal muscle contractions
Sammanfattning : The central nervous system controls human force production by successive recruitment of motor units in the skeletal muscles and changing their neural firing rate. The motor unit comprises a motoneuron, its innervated muscle fibers, and its axons. LÄS MER
2. Flow in contractions with application to headboxes
Sammanfattning : .... LÄS MER
3. Dynamic Fetal and Placental Circulatory Changes during Uterine Contractions
Sammanfattning : The best mode of delivery for fetuses with intrauterine growth restriction (IUGR) and umbilical artery (UA) blood flow changes is not well elucidated. Uterine artery, fetal UA, middle cerebral artery (MCA), and venous blood flow changes during uterine contractions during an oxytocin challenge test (OCT) have not been observed systemically. LÄS MER
4. Muscular force production during non-isometric contractions: Towards numerical muscle modeling
Sammanfattning : The main objective of the study was to investigate skeletal muscle force production during isometric contractions, active muscle stretches and shortenings. The motivation behind this work is to improve the dominant model of muscle contraction force generation based on the theories of Hill. LÄS MER
5. Modelling of muscular force induced by non-isometric contraction
Sammanfattning : The main objective of the study was to investigate and simulate skeletal muscleforce production during and after isometric contractions, active muscle lengtheningand active muscle shortening. The motivation behind this work was to improve thedominant model of muscle force generation based on the theories of Hill from 1938. LÄS MER
