The purpose of the study was to evaluate the effect of long term aerobic exercise on blood pressure, blood lipids and hematological parameters in elderly women. Subjects included twenty elderly women over 65 years old. They were selected from the elderly welfare house located at Sung-nam City. The subjects were subdivided into two groups including exercise group (n=10), and control group (m=10). They were all living in Sung-nam City and regularly go to the elderly welfare house. Anthropometric measurements included body weigh, and height. Blood pressure was measured at the onset and phase Ⅳ of the Korotkoff sounds. After an overnight fast of at least 12 hours blood samples of 10㎖ were drawn from antecubital veins. Serum was then separated for detenmination of total cholesterol, triglycerides, high density lipoprotein cholesterol and low density lipoprotein cholesterol. Hemoglobin, hematocrit, red blood cell, Hemoglobin, hematocrit, red blood cell, mean corpuscular volume, mean corpuscular hemoglobin concentration, and mean corpuscuar hemoglobin were analyzed by automated instrumentation (ADVIA 120. Bayer. USA). Serum iron and total iron binding capacity were datermined by auto-analyzer (HITACHI 7150, Tokyo, Japan) and transfemin saturation was calculated by dividing serum iron concentration by TIBC. The supervised exercise training program was conducted for 16 weeks with 3 days per week, 60 min for each session throughout the entire period of study. The exercise training program included 5-min warm-up for calisthenics and stretching, 50 min for aerobic dancing or ground walking and 5-min for cool-down. The results of the study showed that body weight were significantly increased in control group during the period of study. Systolic and diastolic blood pressure were significantly decreased (p<0.05) for exercise group after 16 weeks of aerobic exercise. Although no difference were found for total cholesterol and triglyceride in exercise group, there were significant increase (p<0.05) for those variables in control group. Significant increase could be observed for RBC in exercising group. Howeverm significant decrease (p<0.01) was found for MCV and MCH in exercise group after 16 weeks of aerobic exercise. This study indicates that long term aerobic exercise has a positive effect on blood pressure and blood lipids. |
