Effects of -3.7α Deletion and Sickle-Cell Trait on Ventilatory and Hemodynamic Responses to Maximum Exercise in Young Saudi Females.

It is concluded that individuals with 3.7 α-globin deletion might have lower fitness capacity, as demonstrated by lower VO2max, which might explain the general lower VO2max in the young women of this population. Furthermore, increments in resting systolic and posteexercise systolic blood pressure in 3.7 α-globin deletion and SCT, respectively, might indicate a future risk of cardiovascular diseases and require attention and extensive studies.
