The Effect of a Short-Term High-Intensity Circuit Training Program on Work Capacity, Body Composition, and Blood Profiles in Sedentary Obese Men: A Pilot Study

Table 2

Blood sample measurements from baseline (before HICT program), weeks 1, 2, and 3 of the HICT program, and after the final exercise session in week 4 (after HICT program). Blood sample measurements and 𝑃 values that are bolded indicate that there was a significant (𝑃<0.05) difference from before HICT program measurements. All data represent means ± SD. Low-density lipoprotein (LDL), high-density lipoprotein (HDL), homeostasis model analysis (HOMA), insulin resistance (IR), and beta cell function (𝛽).
