Characterization of peripheral blood mononuclear cell (PBMC) types in high-fit and low-fit females at baseline and after a recent bout of exercise. Stacked (A) and single percentages of CD14⁺ (B), CD56⁺ (C), CD19⁺CD20⁺ (D), CD3⁺CD8⁻CD4⁻ (E), CD3⁺CD8⁺ (F), CD3⁺CD4⁺ (G), CD3⁺CD4⁺CD25⁺ (H), CD3⁺CD4⁺CD25⁺CD127⁻ (I), and CD3⁺CD4⁺CD25⁺CD127⁺ (J) subsets relative to the total number of viable PBMCs (%) at baseline and postexercise in low-fit (n = 16, left in stacked plot, gray in single plots) and high-fit (n = 15, right in stacked plot, colored in single plots) females. Main effects (fitness level and recent exercise) and interaction effects were analyzed using repeated-measures ANOVA (RM-ANOVA). Significant P values (<0.05) are indicated in bold.
