Fatigue performance of external fixator pins

Journal of Orthopaedic Research, 1984
AbstractThe fatigue performance of several types of commonly used external fixator pins was examined. The pins were tested under a cyclic bending mode. A strength reduction factor (SRF) was defined to quantify the effect of stress concentration caused by the pin threads as compared with the smooth portion of the pin.

Fatigue, Performance, and Overtraining

Medical Problems of Performing Artists, 2010
Almost by definition, the performance of dance, music, or any other performing art involves physical exertion of some type and some degree. In most performances, the amount of energy expended appears to be substantially higher than the resting state but significantly lower than many athletic events that last about the same amount of time.

Reproducibility of performance and fatigue in trail running

Journal of Science and Medicine in Sport, 2014
This study aimed to test the reproducibility of running performance, neuromuscular fatigue markers and indirect muscle damage indicators in a field-based trail time-trial.Running performance and changes in classical physiological parameters were analysed in 11 experienced trail runners before and in the days following four bouts of outdoor trail ...

Fatigue and human performance

2022
Fatigue has been defined differently in the literature depending on the field of research. The inconsistent use of the term fatigue complicated scientific communication, thereby limiting progress towards a more in-depth understanding of the phenomenon.

Effects of Fatigue on Residents’ Performance in Laparoscopy

Journal of the American College of Surgeons, 2015
The influence of fatigue on residents' performance in laparoscopy was prospectively assessed through a computer-based virtual reality simulation (VRS) model.Twenty-six residents (14 novices, 12 experienced) were recruited. In the first stage, each participant was initially tested on 8 VRS-based tasks.

Fatigue performance of rib-to-deck double-side welded joints in orthotropic steel decks

Engineering Failure Analysis, 2019
Fatigue cracking of rib-to-deck welded joints is the major fatigue problem of the orthotropic steel deck (OSD). It is important to evaluate the fatigue performance improvement of rib-to-deck double-side welded joints in an OSD when compared with single ...

Fatigue Behavior of High‐Performance Concrete

Journal of Materials in Civil Engineering, 1993
A fatigue study was performed two commercial high-strength concretes of 70 MPa and 95 MPa with water/cementitious material ratios of 0.28 and 0.23, respectively. Specimens were cast at the construction site and cured in the laboratory. Tests were performed under constant amplitude, and strains were measured continuously using strain gauges.

Fatigue, sleep restriction and driving performance

Accident Analysis & Prevention, 2005
We ran a randomized cross-over design study under sleep-deprived and non-sleep-deprived driving conditions to test the effects of sleep restriction on real driving performance. The study was performed in a sleep laboratory and on an open French highway. Twenty-two healthy male subjects (age = 21.5 +/- 2 years; distance driven per year = 12,225 +/- 4739
