Reduced Electromyographic Fatigue Threshold After Performing a Cognitive Fatiguing Task

Journal of Strength & Conditioning Research, 2021
Abstract Ferris, JR, Tomlinson, MA, Ward, TN, Pepin, ME, and Malek, MH. Reduced electromyographic fatigue threshold after performing a cognitive fatiguing task. J Strength Cond Res 35(1): 267–274, 2021—Cognitive fatigue tasks performed before exercise may reduce exercise capacity. The electromyographic fatigue threshold (EMGFT) is the highest

Drillstring Fatigue Performance

SPE Drilling Engineering, 1990
Summary The life-prediction technique of a whole-life fatigue model was applied to drillstring components. Good agreement existed between the life predictions and the experimental data of drill collars. These life predictions were then used to study the effects of material properties and commonly used thread profiles on the fatigue life ...

Fatigue Transfer in Endurance Performance

Research Quarterly. American Alliance for Health, Physical Education and Recreation, 1976
Abstract Data on 32 male college students were used to test the hypothesis that fatigue products produced by the performance of heavy physical work involving the largest and most powerful muscle groups of the body (legs) would transfer to and impair another immediately following motor performance which utilized musculature that was not active during ...

Respiratory Muscle Fatigue Alters Cycling Performance and Locomotor Muscle Fatigue

Medicine & Science in Sports & Exercise, 2020
ABSTRACT Purpose This study aimed to determine if preexisting respiratory muscle fatigue (RMF) alters motoneuronal output, locomotor muscle fatigue, and cycling performance. Methods Eight trained male cyclists performed 5-km cycling time trials after a resistive breathing ...

Effects of fatigue on golf performance

Sports Biomechanics, 2012
The purpose of this study was to determine if body position, weight transfer, and/or pelvis/trunk rotations changed as a result of a golf specific fatiguing protocol and whether these changes affected resultant club head velocity at impact and shot consistency. Six male golfers and one female golfer participated in the study, who had a mean age, height,

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.

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 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.

Fatigue performances of helicopter gears

Materials Testing, 2023
Abstract Gears are widely used machine elements to transmit power and motion in the industry. During the power transmission, the gears are subjected to cyclic loads. Thus the fatigue resistance of the gears should be deeply investigated. In particular, this issue is gaining much more importance in the space and aviation fields.

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
