Abstract

Purpose: The purpose of this study were to investigate the effects of a 12-week brisk walking program on triglycerides (TG) and apolipoprotein B (Apo B) and to compare these effects to those of a brisk walking plus diet program in middle-aged overweight/obese (BMI> or =23) Korean women with hypertriglyceridemia.

Method: This analysis was done with nineteen middle-aged overweight/obese Korean women who completed either the brisk walking program (9 women) or the brisk walking plus diet program (10 women) for 12 weeks. The brisk walking consisted of walking for 20 to 50 minutes/day at an intensity of 40 to 70% of heart rate reserve (HRR) for 3 to 6 days/week. The diet consisted of 60 minutes of group education and 20 to 30 minutes of individual counseling every week. TG and Apo B were assessed pre- and post-intervention.

Results: TG and Apo B decreased significantly after the brisk walking program (Z = -2.31, p = 0.021; Z = -2.59, p = 0.009). TG and Apo B lowering effects of the brisk walking program were not significantly different from those of the brisk walking plus diet program (U = 37.0, p = 0.549; U = 42.0, p = 0.842).

Conclusion: Brisk walking can be an effective intervention for overweight/obese middle-aged women with hypertriglyceridemia in reducing cardiovascular risk by lowering TG and Apo B levels. Adding diet to brisk walking may have no additional significant effects on changes in TG and Apo B.
