atrophy
Most every kind of disease causes the body weakness and fatigue at some point. In the beginning of a sickness the body instinctively desires rest in order to better consolidate its resources against the viral or bacterial attack. Frequently, over time, weakness and fatigue reappear with a gradual vengeance if a disease is winning, as the body slowly begins to buckle, having consumed its strength fighting. Diseases that are especially known for causing weakness and fatigue: AIDS CFS - Chronic Fatigue Syndrome Malnutrition Mononucleosis Heart conditions Muscular dystrophy Polio Malaria Influenza Cancer
myolysisrhabdomyolysis is the breakdown of muscle fibers. This releases the contents of the fibers into the blood stream. Rhabdomyolysis can be caused by damage to the muscle itself.Muscular AtrophyDegeneration of muscle tissue is known as myolysis.

HIV can affect muscle tone through several mechanisms, primarily related to the virus's impact on the immune system and overall health. Chronic inflammation and the direct effects of HIV can lead to muscle wasting and weakness, known as HIV-associated myopathy. Additionally, opportunistic infections and side effects from antiretroviral therapy can further contribute to changes in muscle tone and strength. As a result, individuals living with HIV may experience decreased muscle mass and altered muscle function.
Atrophy is the wasting away of a body part.
A weakness or slight muscular paralysis is known as paresis. It is characterized by a partial loss of voluntary muscle movement and can be caused by various factors such as nerve damage, stroke, or certain medical conditions. Physical therapy and medications can help manage paresis and improve muscle strength.
The phenomenon known as muscle pump is caused by increased blood flow to the muscles during exercise, which helps deliver oxygen and nutrients while removing waste products.
Low levels of potassium, known as hypokalemia, can lead to muscle cramping. Potassium plays a crucial role in proper muscle function, and a deficiency can result in muscle weakness, spasms, and cramping. Maintaining adequate potassium levels is essential for overall muscle health.
A stroke can lead to increased muscle tone, known as spasticity, in some cases. This can cause muscles to become stiff and resistant to movement. However, in other cases, a stroke can also lead to decreased muscle tone, known as flaccidity, which results in weakness and reduced muscle control. Treatment and rehabilitation aim to manage muscle tone changes and optimize function.
J.R. Poortmans is known for his work in the field of exercise physiology, particularly in studying muscle metabolism and the effects of physical training on performance. He has conducted research on topics such as muscle bioenergetics, endurance exercise, and the physiological adaptations to exercise.
The ability of a muscle to exert maximum force is known as muscle strength. It is typically tested by measuring the maximum amount of force a muscle or muscle group can generate during a specific movement or exercise. Muscle strength is influenced by factors such as muscle size, recruitment of muscle fibers, and neural control.
When one does pull down exercises, they are doing a strength training exercise in which ultimately develops the latissimus dorsi muscle, also known as the back.
