Effects of HIIT on heart rate and blood pressure. Changes of A HR (heart rate), B SBP (systolic blood pressure), and C DBP (diastolic blood pressure) were examined pre- and post-experiment using PASESA AVE-2000 PLUS. n = 13 Control group, n = 17 HIIT group. Repeated measures ANOVA followed by simple effect test analysis were used. Data are presented as mean ± SE. ^*p < 0.05, ^**p < 0.01, HIIT group (post) vs. Control group (post); ^#p < 0.05, ^##p < 0.01, pre vs. post in HIIT group; ^△p < 0.05, ^△△p < 0.01, pre vs. post in Control group
