Effects of HIIT on blood lipids. Changes of A TC (total cholesterol), B TG (Triglyceride), C LDL (Low-density lipoprotein), D HDL (High-density lipoprotein), and E TC/HDL (Total cholesterol/High-density lipoprotein) were examined pre- and post-experiment using Cholesterol Monitoring system CCM-111. 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 < 0.01, pre vs. post in HIIT group; ^△p < 0.05, pre vs. post in Control group
