Figure 2. Flow cytometric analysis of apoptosis and autophagy in CD4 lymphocyte (Day 0).

Graph showing the flow cytometric analysis of high intensity-interval (HIT) (A) and moderate intensity-continuous (MCT) (B) exercise training effects on main biomarkers of apoptosis and autophagy [i.e., LAMP-2, active caspase -3, and annexin V staining (phosphotidylserine exposure)] in untreated CD4 lymphocytes (Day 0). Pre, pre-intervention; Post, post-intervention; Rest, resting; HE, hypoxic (12%O₂) exercise test; Basal, untreated CD4 lymphocytes (Day 0).
