The impact of moderate and high intensity total body fatigue on passing accuracy in expert and novice basketball players [PDF]

, 2007
Despite the acknowledged importance of fatigue on performance in sport, ecologically sound studies investigating fatigue and its effects on sport-specific skills are surprisingly rare.

Study on the evolution mechanism of concrete properties under the coupled effects of freeze-thaw cycle, chloride salt and fatigue loading

Frontiers in Physics
The long-term durability performance of ballastless track systems exhibits significant dependence on their in-service environmental conditions. In addition to cyclic fatigue loading from train operations, critical durability challenges arise from the ...

Changes in the flexion relaxation response induced by lumbar muscle fatigue

BMC Musculoskeletal Disorders, 2008
Background The flexion relaxation phenomenon (FRP) is an interesting model to study the modulation of lumbar stability. Previous investigations have explored the effect of load, angular velocity and posture on this particular response.

Monitoring Training Load to Understand Fatigue in Athletes [PDF]

Sports Medicine, 2014
Many athletes, coaches, and support staff are taking an increasingly scientific approach to both designing and monitoring training programs. Appropriate load monitoring can aid in determining whether an athlete is adapting to a training program and in minimizing the risk of developing non-functional overreaching, illness, and/or injury.

Vehicle Load Spectrum and Fatigue Vehicle Model of a Long-Span Concrete-Filled Steel Tube (CFST) Arch Bridge Based on Measured Data of Weight-In-Motion System

Advances in Civil Engineering, 2022
Highway traffic load, speed, and volume have been increasing continuously over the years. Because of its special structural form, the fatigue problem of a long-span concrete-filled steel tube arch bridge becomes more and more serious.

Harmonic Equivalence of the Impulse Loads in Vibration Fatigue

Strojniški vestnik – Journal of Mechanical Engineering, 2019
In vibration fatigue, three unique types of loads are typical: random, harmonic and impulse. In an application any of these loads are possible. A fatigue-life analysis is possible in the time and frequency domains using the frequency-response function of a structure. Recent studies demonstrated that the impulse loads influence the accuracy of a fatigue-

Digital Cognitive Testing in Mitochondrial Disease: Validity and Challenges for Clinical Trial Use

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Primary mitochondrial disease is a group of genetic disorders caused by pathogenic variants in nuclear or mitochondrial DNA, often resulting in progressive neurodegeneration and cognitive decline. Current management is primarily supportive, though recent research offers hope for disease‐modifying treatments in the future.
