Comparison effect of sub maximal aerobic training on lipid profiles and Apo lipoproteins A-1 and B in overweight women

Traditionally, LDL-C, HDL-C and lipid ratios are risk factors of cardiovascular (CV) disorders. Nevertheless, there is evidence that indicates apoB, apoA-I, and especially the apo-ratio, are better than conventional lipids to predict CV risk and during lipid-lowering treatment. Thereby, the aim of this study was to compare the changes of LDL-C, HDL-C, TG, apoB and apo A-1 concentration, Apo-ratio, as well as cholesterol, and BMI follow aerobic exercise training in overweight women.
Subjects and Twenty-four healthy but overweight women participated in the study. Subjects were divided into two groups control (C) and experimental (E) groups, (n=12 in each). Aerobic exercises were conducted for 8 weeks/3 sessions/week with 60-75% heart rate max. Blood samples before and after exercise were collected before starting the protocol and after the last session of the exercise training. For data analysis t-student test was used to compare mean differences between groups.
Based on our results, TG, TC, and apoA1, and apo reatio significantly decreased and HDL levels increased markedly following aerobic protocol. In contract, LDL and apo-B did not change significantly in compare with the control group.
Such results suggest that changes in the levels of lipid profiles are in relationship with apoA-1, apo-B, and aporatio.
