1. Muscle Thixotropy : Implications for Human Motor Control
Sammanfattning : Human skeletal muscles possess thixotropic, i.e. history-dependent mechanical properties. This means that the degree of passive muscle stiffness and resting tension is dependent on the immediately preceding history of contractions and length changes. LÄS MER
2. Classification of muscle stretch receptor afferents in humans
Sammanfattning : The response patterns of human stretch receptors in the finger extensor muscles of the forearm were studied using the microneurography technique. Single-unit recordings were obtained from one-hundred and twenty-four afferents. LÄS MER
3. Muscular forces from static optimization
Sammanfattning : At every joint there is a redundant set of muscle activated during movement or loading of the system. Optimization techniques are needed to evaluate individual forces in every muscle. The objective in this thesis was to use static optimization techniques to calculate individual muscle forces in the human extremities. LÄS MER
4. The Fight on the Flights : Emergency evacuations – human physiological performance, leg muscle activity and gait biomechanics during exhaustive stair and slope ascent
Sammanfattning : Physical exhaustion can constrain stair ascending capacity during emergency evacuation. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations when using two different modes: 1) self-preferred pace on three different public stairways, and 2) four machine-controlled paces on a stair machine corresponding to different percentages of maximal aerobic capacity (V̇O2max).

5. Mastication in jaw muscle pain
Sammanfattning : Background: Integrated Pain Adaptation Models suggest a possible pain-motor interaction. Mechanisms affecting the jaw muscle spindles seem to affect the ability to bite and chew, suggesting that jaw muscle pain may be a potential modifier of mastication in humans. LÄS MER
