Step-Aerobics Versus Core Exercise for Non-HDL Cholesterol Reduction in Sedentary/Obesity Women

Step-Aerobics Versus Core Exercise for Non-HDL Cholesterol Reduction in Sedentary Women With Overweight/Obesity

This study investigated the effects of a step-aerobics program versus a core exercise program on serum non-HDL-C levels and other cardiometabolic parameters in sedentary women with overweight/obesity.

Non-high-density lipoprotein cholesterol (non-HDL-C) is a key predictor of cardiovascular disease (CVD), yet the comparative effects of different exercise modalities on this marker, particularly in high-risk populations, are not fully understood.

This study will investigate the effects of a step-aerobics program versus a core exercise program on serum non-HDL-C levels and other cardiometabolic parameters in sedentary women with overweight/obesity.
