Fig. 2. Selected metabolic variables before and after exercise. (A) ALT, (B) AST, (C) insulin, (D) HOMA-IR, (E) TG, (F) TC, (G) HDL, and (H) LDL. Data are mean±standard error. Significance: p≤error. Significance: lipoprotein cholesterol. Data are mean±-post). ^*Differences between time points within condition (pre-post). ^†Differences between training groups vs. control group. ^‡Differences between training groups.

SBE: school-based exercise, HIIT: high-intensity interval training, CG: control group, ALT: alanine aminotransferase, AST: aspartate aminotransferase, HOMA-IR: homoeostasis model assessment for insulin resistance, TG: triglyceride, TC: total cholesterol, LDL-C: low-density lipoprotein cholestero, HDL-C: high-density lipoprotein cholesterol.
