Muscle fatigue is not the same as muscle weakness, though weakness is an initial symptom. Despite a normal amount of force being generated at the start of activity, once muscle fatigue has set in and progressively worsens, if the individual persists in the exercise they will eventually lose their hand grip, or become unable to lift or push with ...
The term 'fibromyalgia' is from Neo-Latin fibro-, meaning 'fibrous tissues'; Greek μυο- myo-, 'muscle'; and Greek άλγος algos, 'pain'; thus, the term literally means "'muscle and fibrous connective tissue pain'. [15] Fibromyalgia is estimated to affect 2 to 4% of the population. [16] Women are affected about twice as often as men.
Physical fatigue, or muscle fatigue, is the temporary physical inability of muscles to perform optimally. The onset of muscle fatigue during physical activity is gradual, and depends upon an individual's level of physical fitness – other factors include sleep deprivation and overall health. [131]
Myalgia or muscle pain is a painful sensation evolving from muscle tissue. It is a symptom of many diseases . The most common cause of acute myalgia is the overuse of a muscle or group of muscles ; another likely cause is viral infection , especially when there has been no injury .
Compassion fatigue, a lessening of compassion common among those who work with trauma victims; Muscle fatigue, the decline in ability of a muscle to generate force, also known as peripheral fatigue; Battle fatigue/Combat fatigue, an outdated term for: Combat stress reaction, a military term for short-term behavioral disorganization
This meaning implies that the primary defect is within the muscle, as opposed to the nerves ("neuropathies" or "neurogenic" disorders) or elsewhere (e.g., the brain). This muscular defect typically results in myalgia (muscle pain), muscle weakness (reduced muscle force), or premature muscle fatigue (initially normal, but declining muscle force).
Two overlapping symptoms can be present: Increased fatigue after mental exertion can be associated with a reduction in cognitive function. Minimal physical effort might be felt as extreme fatigue along with pain and anxiety. Many other symptoms of bodily discomfort may be felt with either form.
Prolonged stress can disturb the immune, digestive, cardiovascular, sleep, and reproductive systems. [17] For example, it was found that: Chronic stress reduces resistance of infection and inflammation, and might even cause the immune system to attack itself. [27] Stress responses can cause atrophy of muscles and increases in blood pressure. [28]
