[Effect of 8-week walking program on serum lipoprotein [a] concentration in non-athlete menopausal women]

ABSTRACT

Lipoprotein [a] [Lp[a]] is a new cardiovascular risk factor and its concentration increase cardiovascular diseases, while physical activity decrease cardiovascular diseases. This study intend to investigate the effect of eight week walking program on lipoprotein [a] concentration in non-athlete Iranian menopausal women. Twenty two healthy menopause women of 47-55 year of age any specific disorder were enrolled in this study. The subjects randomly divided into experimental and control groups. Anthropometric characteristics including height, weight, body mass index [BMI], body fat percent and Waist-to-Hip ratio [WHR] and serum lipoprotein on fasting were measured pre and post-walking program. The data were compared using independent t-test, U mann witny and pearson correlation coefficient was used for assessement of relation between lipoprotein [a] with anthropometric indexes. According to these results, there was a significant reduction of serum lipoprotein [a] [pre test12.5 +/- 4/1; post test 10.5 +/- 3md], WHR, BMI and body fat percent prior and after the training in experimental group [P<0.05] while non significant changes was observed in control group. Also, there was non significant relationship between lipoprotein [a] with Anthropometric indexes. This study revealed that 8-week walking program had useful effects on menopausal women' serum lipoprotein [a] concentration, WHR, BMI and body fat percent
