Monocyte changes in response to 10 weeks of high-intensity interval training (HIIT). a Representative forward vs. side scatter of cluster of differentiation 16 (CD16) expression on CD14+ monocytes. Frequency of (b) total CD16-expressing monocytes, (c) intermediate monocytes, and (d) nonclassical monocytes pre- and post-HIIT training. Surface expression of (e) Toll-like receptor 2 (TLR2), (f) TLR4, and (g) human leukocyte antigen (HLA)-DR on intermediate monocytes pre- and post-HIIT training. h Phagocytosis of fluorescein isothiocyanate-labeled Escherichia coli pre- and post-HIIT training. All data are mean ± SEM (n = 12). MFI Median fluorescence intensity
