Fatigue is a common and disabling symptom in multiple sclerosis but is poorly understood. We investigated 'physiological' fatigue in 21 patients with multiple sclerosis who complained of disabling fatigue by measuring the decline in strength during a 45 s maximal contraction of the adductor pollicis muscle. The results were compared with those from a control group of 19 healthy subjects. The st...

Cold-in-place recycling (CIR) is an environmentally sustainable alternative for preservation of asphalt pavements. A major disadvantage of this practice is the lower strength of the cold-in-place mixtures. Addition of cement into this type of mixture is a method for increasing its bearing capacity. The effect of cement content on the mechanical properties of the cold-in-place recycled asphalt m...

OBJECTIVE To determine the association between the 5 subscales of the Multidimensional Fatigue Inventory (MFI-20) and physical function in late mid-life. DESIGN Cross-sectional study. SUBJECTS A population-based sample of adults who participated in the Copenhagen Aging and Midlife Biobank population cohort (n = 4,964; age 49-63 years). METHODS Self-reported fatigue was measured using the ...

This paper presents the results of an experiment to investigate the high cycle fatigue properties of the ultra-high strength steel TM210A. A constant amplitude rotating bending fatigue experiment was performed at room temperature at stress ratio R = -1. In order to evaluate the notch effect, the fatigue experiment was carried out upon two sets of specimens, smooth and notched, respectively. In ...

BACKGROUND Respiratory muscle weakness occurs in sarcoidosis and is related to decreased exercise capacity, greater fatigue, dyspnea, and lower quality of life in sarcoidosis patients. The effects of inspiratory muscle training in this population have not been comprehensively investigated so far. This study was planned to investigate the effects of inspiratory muscle training on exercise capaci...

Stabilizer bar is an important component of the vehicle’s independent suspension system and plays an important role in the safety traffic. Therefore, the research on fatigue strength characteristics of the automobile stabilizer bar is very important. In this paper, the finite element model is established for the automobile stabilizer bar by utilizing ANSYS finite element analysis software. The ...

The low-back pain has demonstrated to be a common finding among athletes and particularly the overload in the lumbar column resulting from a strength or isometric resistance involvement of muscles of this segment as result of the muscular fatigue has been considered as important etiological factor for its development. In this context, tests used for the training evaluation of the lumbar spinae ...

The aim of this case–control study was to investigate the prevalence of exercise intolerance, muscle weakness and fatigue in sarcoidosis patients. Additionally, we evaluated whether fatigue can be explained by exercise capacity, muscle strength or other clinical characteristics (lung function tests, radiographic stages, prednisone usage and inflammatory markers). 124 sarcoidosis patients (80 ma...
