Background and purpose: Homocysteine is a new cardiovascular risk factorthatits enhancement can cause increase in cardiovascular diseases. Because of physical activity importance in cardiovascular diseases prevention (specially in older people) this study intend to investigate the effect of 8-week low impact rhythmic aerobic (LIA) exercise on total plasma homocysteine concentration in non athlete Iranian older women for first time.
Materials and methods: Twenty five healthy women of (60-85) in Taravat retirement home at Shahrekord were the statistical sample of this study. They were purposefully divided in to two groups: (including) experimental and control. The Control group was also able to do the physical activity. At first, anthropometric characteristics including height, weight, Body Mass index (BMI) and Waist-to-Hip Ratio(WHR) were measured and recorded. Then resting blood sampling was taken from anterior vein in 5cc amount, while they did not eat any breakfast for 8-hours. Experimental group were directed to the LIA exercise program such as musical aerobic exercise with 40 percent of maximum heart rate for 15 minutes in first week and with 65 percent maximum heart rate for 40 minutes in the final week. Then WHR, BMI, resting blood sampling and total plasma homocysteine were measured again.
Results:For pre-test and post-test data comparison in two groups paired t-test and between groups in dependent t-test and Pearson correlation coefficient for assessment of relationship between homocysteine with WHR and BMI were applied. According to these results, there was a significant difference between total plasma homocysteine, BMI and WHR before and after the training in experimental group while nonsignificant difference was observed in control group. In investigating the relationship among these factors in experimental group, although there was not a meaningful relationship between BMI & homocysteine, a direct but incomplete relationship was observed (p=0.372, r=0.27) and also, between homocysteine and WHR in this group has been obtained similar results to previousone was obtained. In control group no significant relationship was observed among the variables.
Conclusion:Observations from this study, reveals that an 8-week low impact rhythmic aerobic training had useful effects on older women’s total plasma homocysteine concentration BMI & WHR reduction.
