6. Postural and Muscular Responses of Car Occupants under Pre-Crash Conditions
Sammanfattning : Advanced integrated safety technologies in modern cars such as collision avoidance intervention and pre-crash activated restraint systems require comprehensive research on how vehicle occupants respond to these systems. The aim of this thesis is to provide insights into car passengers’ body kinematics and muscle activations in representative pre-crash circumstances with respect to two belt configurations (i. LÄS MER
7. Between Ourselves : Automatic mimicry reactions as related to empathic ability and patterns of attachment
Sammanfattning : This thesis investigated emotional communication in experimentally created face-to-face interaction situations. The hypotheses were based on the conception of a process which leads to emotional empathy, assuming that automatic mimicking tendencies are involved in an automatic part of the process. LÄS MER
8. Trapezius muscle fatigue and electromyographic frequency analysis
Sammanfattning : This study, comprising 6 separate articles, is concerned with different validity and reliability aspects of the electromyogram mean power frequency (MPF) as an estimator of localized musele fatigue in the trapezius muscle. A series of new, and partly controversial and problematic findings are reported. LÄS MER
9. 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
10. Performance and Flotation-REST in Tests of Marksmanship, Problem-solving and Perceived Exertion
Sammanfattning : This present thesis examines whether or not relaxation as floating may be exploited to reinforce primary process (inner-directed) orientation, and thereby enhance performance, creative problem-solving ability and originality. Two Articles are presented both using randomized factorial design. Article I include two subexperiments. LÄS MER
