generally, fatigue failure in an element happens at the notch on a surface where the stress level rises because of the stress concentration effect. the present paper investigates the effect of a notch on the fatigue life of the hsla100 (­high strength low alloy) steel which is widely applicable in the marine industry. tensile test was conducted on specimens and mechanical properties were obtain...

this study aims to consider the relationships between job fatigue, organizational citizenship behavior and organizational atmosphere. the evaluation of each variable is a kind of decision making problem which has systematic transaction between variables. so, decision making trial and evaluation laboratory (dematel) is suitable for defining the cause and effect relationships between variables. w...

objectives the aim of this study was to examine temporal changes in technical and physical performances during a small-sided game (ssg) in elite soccer players. methods sixty elite youth players (age 14.8 ± 0.2 yr; stature 177 ± 5 cm; body mass 66.2 ± 4.7 kg) completed a 5 v 5 ssg using two repetitions of 8 minutes interspersed by 3 minutes of passive recovery. to evaluate temporal changes in p...

Background: High rates of medical errors have been documented within the healthcare industry. Fatigue is a factor that has been linked to performance decrements in numerous industries, including healthcare. Due to the nature of their work, nurses may be particularly susceptible to multiple dimensions of fatigue, and their performance is closely linked to patient safety. Objectives: Perceived le...

introduction: sensory-motor control and in general gaining balance will be impaired after an ankle injury and in fatigue situations. the aim of this research was to study the effect of exercise-based fatigue on static and dynamic balance in mountaineering athletes who were successful in returning to a suitable level of physical activity after an ankle sprain injury. materials and methods: 25 ac...

Objectives: Skeletal-muscular disorders affect the biomechanics of the human body, especially the lower extremity, with a negative effect on the biomechanics of exercise. The main aim of this study was to evaluate the effect of fatigue on the kinematic variables of knee joints during countermovement jumps in female students of physical education with valgus knee deformity.  Methods: Fifte...

Fibromyalgia is a condition characterized by chronic widespread muscle pain and fatigue. The primary objective of this study was to determine if pain, perceived cognitive fatigue, and perceived physical fatigue were enhanced in participants with fibromyalgia compared to healthy controls during a cognitive fatigue task, a physical fatigue task and a dual fatigue task. Twenty four individuals wit...

This paper reviews the current literature examining the pervasive symptom of fatigue experienced in three of the most common degenerative neurological conditions: multiple sclerosis (MS), Parkinson’s disease (PD) and post-polio syndrome (PPS). The existing literature can be considered under four headings definition and prevalence, type, cause, impact of fatigue. Fatigue is a common symptom in d...
