Input: Question: Are impaired oxygen on-kinetics in persons with human immunodeficiency virus due to highly active antiretroviral therapy?
Answer: Oxygen on-kinetics during submaximal exercise above the ventilatory threshold was impaired in HIV-positive participants compared with a control group, and it appeared that the attenuated oxygen on-kinetic response was primarily caused by HIV infection rather than HAART.
Output:
no
