Respiratory muscle work and inspiratory muscle training on cytokines, oxidative stress and diaphragm fatigue in younger and older populations [PDF]

, 2013
Increased respiratory muscle work is encountered during strenuous whole-body exercise, and at rest in older adults and those with pulmonary limitations such as chronic obstructive pulmonary disease (COPD).

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.

The effect of muscle fatigue on the behavior of single muscle fibre [PDF]

Applied and Computational Mechanics, 2007
The aim of this study is to integrate the effect of muscle fatigue into skeletal muscle fibre model. The base of the skeletal muscle model previously developed in our laboratory is the sliding cross bridge theory of contraction.

Multi-scale modeling and simulation of skeletal muscles with different fatigue degrees based on microphysiology

Scientific Reports
The ability for skeletal muscle to constantly generate force is limited by the muscle fatigue. The calcium ion plays a significant role of the cross-bridge cycle under fatigue conditions in the force generation of skeletal muscle.

Characterization of Muscle Fatigue Degree in Cyclical Movements Based on the High-Frequency Components of sEMG

Biomimetics
Prolonged and high-intensity human–robot interaction can cause muscle fatigue. This fatigue leads to changes in both the time domain and frequency domain of the surface electromyography (sEMG) signals, which are closely related to human body movements ...

Effects of static exercises on hip muscle fatigue and knee wobble assessed by surface electromyography and inertial measurement unit data

Scientific Reports
Hip muscle weakness can be a precursor to or a result of lower limb injuries. Assessment of hip muscle strength and muscle motor fatigue in the clinic is important for diagnosing and treating hip-related impairments.

Stimulation-Induced Muscle Deformation Measured With A-Mode Ultrasound Correlates With Muscle Fatigue

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Muscle fatigue is a common physiological phenomenon whose onset can impair physical performance and increase the risk of injury. Traditional assessments of muscle fatigue are primarily constrained by their dependence on maximum voluntary contractions ...
