In the majority of the shoulder muscles, the proportions of fatigue resistant slow-twitch fibers (SO) and fatigable fast-twitch fibers (FG) were inversely related to each other, whereas the percentage of intermediate FOG-fibers varied independently.
The highest proportions of fatigue (76%) and headache (38%) were observed on March 18 and 23, respectively, in Yaoundé.
A life prediction model has shown that nucleation occurs after few cycles at high strain ranges whereas a large proportion of the fatigue life is consumed in the nucleation process at low strain ranges.
In addition, single-lap joints were tested under cyclic fatigue loading in the two test environments, and a back-face strain technique has been used which revealed that crack propagation, rather than crack initiation, occupied the dominant proportion of the fatigue lifetime of the single-lap joints.
The resistance of each period can be evaluated according to its proportion of the whole fatigue failure process.
With regard to gender differences in HRQoL, larger proportion of women suffered fatigue and insomnia than men.
In a similar pattern to the ATTAIN trial, 2 years of treatment with abatacept decreased the proportion of patients with fatigue, pain, and sleep problems (Dougados et al. 2007a).
29 Thus, perhaps, the contralateral leg, which was significantly less painful than the involved leg, had a lower decline rate in type II fast-twitch fibers, resulting in a lower proportion of type I fatigue-resistant fibers.
A small number of patients recover from cancer-related fatigue after cessation of treatment, but in a significant proportion of cancer survivors the fatigue persists for several months or even years.
In a variable proportion of cases, polyarthritis and fatigue can persist for 2 years or longer (1 ).
