This study measures the effect of exercise on a variety of biomarkers in blood and urine selected to evaluate the physiological pathways of hemolysis, myolysis, thrombosis, inflammation, and renal function in subjects with sickle cell trait. These pathways have been shown to be associated with adverse events in athletes and warfighters with SCT upon protracted, repeated, strenuous exertion. Changes in biomarkers post-exercise compared to pre-exercise (and compared to healthy controls) suggest activation of the associated pathway(s) which may contribute to exercise-related events in athletes and warfighters and subclinical complications in non-athletes.
