Exercise increases muscle performance. You can train your muscles to be more fatigue resistant, larger, stronger, and more powerful. It all depends on the selection of what are known as acute variables. Acute variables include sets and repetitions performed, tempo, intensity, and rest period given between sets.
Signs and symptoms [edit]. The anti glomerular basement membrane (GBM) antibodies primarily attack the kidneys and lungs, although, generalized symptoms like malaise, weight loss, fatigue, fever, and chills are also common, as are joint aches and pains.
AchR antibodies hinder the action of acetylcholine, a chemical (neurotransmitter) that transmits messages between nerve cells. The antibodies do this in three major ways:  1 Binding antibodies attach to the acetylcholine receptors on nerve cells and may initiate an inflammatory reaction that destroys them.n acetylcholine receptor (AChR) antibody test is used to help diagnose myasthenia gravis (MG) and to distinguish it from other conditions that may cause similar symptoms, such as chronic muscle fatigue and weakness.
