While more research is necessary on the topic, the correlation found between individuals with sickle cell trait and an increased risk of sudden death appears to be related to microcirculatory disorders, during exercise.[28] In recent years the NCAA has partnered with the ACSM and issued a joint statement, warning athletes about both the prevalence and the potential risk factors of sickle cell trait.[29] The NCAA has also recently encouraged athletes to become aware of their sickle cell trait status, as the trait itself does not typically result in symptoms under normal conditions but can become dangerous during extreme physical activity similar to the daily training that athletes undergo.
