Acute moderate exercise does not further alter the autonomic nervous system activity in patients with sickle cell anemia.
A decreased global autonomic nervous system (ANS) activity and increased sympathetic activation in patients with sickle cell anemia (SCA) seem to worsen the clinical severity and could play a role in the pathophysiology of the disease, notably by triggering vaso-occlusive crises. Because exercise ch...
