The ability to identify physiologic fatigue and related changes in kinematics can provide an important tool for diagnosing fatigue-related injuries. This study examined an exhaustive cycling task to demonstrate how changes in movement kinematics and variability reflect underlying changes in local muscle states. Motion kinematics data were used to construct fatigue features. Their multivariate a...

According to the actual working conditions of the Vribbed belt, automobile V-ribbed belt fatigue tester machine is designed to test for the automobile engine Vribbed belt fatigue wear. Finite-element analysis software ANSYS is employed to perform finite-element analysis on fatigue testing machine load shaft, bearing, universal joint key parts of the finite-element analysis, and to analyze the m...

BACKGROUND Fatigue is one of the most common presenting symptoms in primary care in Korea. In this study, we aimed to determine the effect of exercise intervention on the severity of fatigue of unknown medical cause during a period of follow-up. METHODS We used the data collected from an outpatient fatigue clinic in Seoul National University Bundang Hospital. The study was conducted from Marc...

Background: Fatigue is among the most common complications for hemodialysis patients. The theory of unpleasant symptoms is associated with fatigue in hemodialysis patients. According to this theory, fatigue has three physical, mental and situational factors. Considering this theory,   we aimed to determine some factors related to fatigue in hemodialysis patients. Methods: In this des...

vocal fatigue is a voice symptom which is frequently reported by professional voice users. teachers, singers, actors and other professions that require prolonged voice use are especially at-risk group. the vocal fatigue results in auditory perceptual and acoustic changes in the voice signal and can lead to serious pathological conditions. the present study has examined acoustic manifestations o...

A brief analysis of entropy concepts in continuum mechanics and thermodynamics is presented. The methods of accounting for friction, wear and fatigue processes in the calculation of the thermodynamic entropy are described. It is shown that these and other damage processes of solids are more adequately described by tribo-fatigue entropy. It was established that mechanothermodynamic entropy calcu...
