Figure 5

Effects of HIIT performed in single versus three shorter daily sessions on cardiac function and hypertrophy. Index of contractility (+ dT/dt) (A). Index of relaxation (− dT/dt) (B). Intrinsic heart rate (bpm) (C). Heart /body mass ratio (mg/g) (D). Left ventricle /body mass ratio (E). N = 10/group. Data are presented as mean ± SD. One-way ANOVA followed by the Tukey test. *p < 0.05, HIIT groups versus Untrained Group. 1xHIIT: High-Intensity Interval Training performed in single daily sessions; 3xHIIT: High-Intensity Interval Training performed in three shorter daily sessions.
