ABSTRACT
Regarding the importance of physical activity in preventing lipids disorders, this study was done with the goal of
comparing one type of aerobic exercise in open and closed place on some lipids intensify CVD disorders, In this
study, 45 healthy middle aged postmenopausal women were randomly divided into 3 groups of 15, tow earobic
exercise and control. First, the heart rate was measured (04/15 ± 47/80), then maximal oxygen consumption (22.65
± 1.46) and the body dimensions, including height (156.7 ± 6.72) weight (68.87 ± 9.22) and body mass index (28.74
± 1.78), then, cholesterol, VLDL and triglycerides values were studied in Laboratory. Time and intensity of exercise
were identical for two groups. Increasing intensity of 50-70% of maximum heart rate was in 12 weeks, 30 to 90
minutes, and 5 times a week (30 minutes at 50% MHR intensity for the first week and 90 minutes of 70 percent MHR
in the last week). After the training period, cholesterol, VLDL and triglycerides values were measured again and the
data were analyzed with the dependent T-test, MANOVA and TUKY follow-up test. The results indicate that
differences between exercise groups and control group were significant. Accordingly, the results of exercise group
in open place had significant effects on reducing mean cholesterol, VLDL and triglycerides (P≤0.05). And aerobic
exercise in closed place had significant effects on reducing mean cholesterol, VLDL but had not significant effects
on reducing mean triglycerides and there was significant difference in VLDL values between two groups after 12
weeks (P≤0.05) as the open place group showed higher mean. As the exercise group in open place showed higher
mean, this study showed that aerobic exercise, either exercise group in open place or in the exercise group in closed
place causes decrease in the mean of some blood lipids like cholesterol, VLDL and triglycerides in postmenopausal
women, among which exercise group in open place maby because of more exciting time indicates greater
effectiveness.
