Framework for Dynamic Evaluation of Muscle Fatigue in Manual Handling Work [PDF]

, 2008
Muscle fatigue is defined as the point at which the muscle is no longer able to sustain the required force or work output level. The overexertion of muscle force and muscle fatigue can induce acute pain and chronic pain in human body. When muscle fatigue

Daytime Exposure to Blue-Enriched Light Counters the Effects of Sleep Restriction on Cortisol, Testosterone, Alpha-Amylase and Executive Processes

Frontiers in Neuroscience, 2020
Sleep debt is becoming a better acknowledged cause of physiological stress and neurobehavioral deficits with major public-health concerns. We investigated whether exposure to blue light during daytime could be an efficient countermeasure to limit sleep ...

Early Relationships of a Low‐Energy Diet With Symptoms of Fibromyalgia

ACR Open Rheumatology, 2022
Objective Previous studies have demonstrated that weight loss has been shown to improve pain in weight‐bearing joints, and more recent studies suggest that weight loss may be accompanied by improvements in pain in non–weight‐bearing regions.

Postural destabilization induced by trunk extensor muscles fatigue is suppressed by use of a plantar pressure-based electro-tactile biofeedback [PDF]

, 2008
Separate studies have reported that postural control during quiet standing could be (1) impaired with muscle fatigue localized at the lower back, and (2) improved through the use of plantar pressure-based electro-tactile biofeedback, under normal ...

Stress biomarkers, mood states and sleep during a major competition: success and failure athlete’s profile of high-level swimmers.

Frontiers in Physiology, 2016
The aim of this study was to evaluate stress markers, mood states and sleep indicators in high-level swimmers during a major 7-days competition according to the outcomes. Nine swimmers (6 men and 3 women (age: 22 ± 2 years and 22 ± 4 years, respectively)
