Abstract
Purpose: Considering the relationship between vascular problems and low-density lipoprotein (LDL), the purpose of this research was to investigate the relationship between baseline levels of LDL, and CAVI and ABI (indices of arterial stiffness), following glucose ingestion and exercise. Materials and Methods: This intervention and trial research was conducted on 82 inactive subjects (40 women and 42 men) in the age group of 20 to 45 years, Shahrood city. After 12 hours of fasting, low density lipoprotein cholesterol (LDL) were measured. Then measurements of weight, height, body composition and arterial stiffness (cardiovascular index-ankle index (CAVI) and brachial-ankle index (ABI)) were taken at baseline and response 30 minutes of acute endurance activity with 65% maximum heart rate was performed on the treadmill. After that, consumption of 75 grams of glucose in 225 ml of water was done in 5 minutes, and finally, after 1 hour of inactive rest, arterial stiffness was measured again. Data analysis was performed using simple linear regression. Results: There is no significant relationship between LDL levels and baseline levels of CAVI index in both male and female groups (p>0.05). But, there is a significant relationship between baseline LDL levels and CAVI index changes (changes in the second stage of measurement after intervention compared to rest levels) in both male and female groups (p=0.001). Also, changes in ABI index were significantly related to LDL only in the male group (p=0.013). Conclusion: In general, it can be concluded that the baseline levels of LDL, can affect the arterial stiffness response to exercise and glucose consumption. The results show that CAVI response was significantly related to LDL levels in both male and female groups. Also, gender was effective in the way of this relationship, because the relationship between ABI response and LDL was only in the male group.
