Plus-minus values are means ± SD with postintervention means being adjusted for covariates of baseline values, waist circumference, and waist-to-height ratio, and data in parentheses are 95% CI. Mean difference is based on rowing group minus multimodal group after the intervention. HDL-c = high-density lipoprotein; LDL-c = low-density lipoprotein; ALT = alanine aminotransferase; AST = aspartate aminotransferase; MM-HIIT = multimodal high-intensity interval training; R-HIIT = rowing high-intensity interval training.
