The syndrome variously called Da Costa's syndrome, effort syndrome, neurocirculatory asthenia, etc has been studied for more than 100 years by many distinguished physicians. Originally identified in men in wartime, it has been widely recognised as a common chronic condition in both sexes in civilian life. Although the symptoms may seem to appear after infections and various physical and psychol...

In this study the effects of surface texture on the fatigue life of a high-strength low-alloy steel were evaluated in terms of the apparent fatigue stress concentration. An abrasive waterjet was used to machine uniaxial dogbone fatigue specimens with specific surface quality from a rolled sheet of AISI 4130 CR steel. The surface texture resulting from machining was characterized using contact p...

Exercise-induced fatigue is charactered by the feeling of tiredness and a decrease in muscle performance resulting from intense prolonged exercise. With development modern society, exercise-induced has become widespread problem besetting people's daily life. Over years, increasing attention been paid to study anti-fatigue peptides. Several animal models have developed mimic fatigue, which could...

BACKGROUND Fatigue is associated with loss of independence in older adults; however, little is known about optimal treatment or how fatigue manifests in daily life activities. "Fatigability" was recently proposed to clarify the fatigue-activity relationship. The purpose of this study was to present a new measurement method of fatigability and begin to test its validity. METHODS Our sample inc...

BACKGROUND Fatigue is the most frequent symptom reported by patients with chronic illnesses. As a subjective experience, fatigue is commonly assessed with patient-reported outcome measures (PROMs). Currently, there are more than 40 generic and disease-specific PROMs for assessing fatigue in use today. The interpretation of changes in PROM scores may be enhanced by estimates of the so-called min...
