Figure 3

Effects of HIIT performed in single versus three shorter daily sessions on body composition, visceral fat mass, adipocyte size, and muscle fiber diameter (gastrocnemius muscle). Body fat percentage (%) (A, N = 10); lean mass (g/g) (B, N = 10); visceral fat mass (g) (C, N = 10); adipocyte area (µ2) (D, N = 72 cells/group from four independent experiments); representative H&E slides of adipocytes in the retroperitoneal fat (E); muscle fiber diameter (gastrocnemius, F, N = 49 fibers/group from four independent experiments); representative H&E slides of gastrocnemius muscle (G). Data are presented as mean ± SD. One-way ANOVA followed by Tukey test. *p < 0.05, HIIT groups versus Untrained group; and #p < 0.05, 3xHIIT versus 1xHIIT group. 1xHIIT: High-Intensity Interval Training performed in single daily sessions; 3xHIIT: High-Intensity Interval Training performed in three shorter daily sessions.
