Abstract
Combinations of various types of dynamics of integrated synchronously recorded bioelectrical activity of the gastrocnemius (lateral and medial) and soleus muscles were analyzed in healthy test subjects and patients with occlusive diseases of vessels of the lower limbs (obliterating endarteritis and atherosclerosis), who performed static work “to capacity”, maintaining a load of 50% of the maximum force of the muscles (plantar flexors of the sole of the foot). The frequency analysis of the elicited types of changes in the electromyogram integrals and their combinations testifies to general regularities in the functional organization of voluntary organization of an effort when fatigue develops in test subjects of two groups, and some features in the conjugate activity of the muscles ascribed to the group of the so-called “principal synergists,” recorded only in the patient group.
