Association of Arterial Stiffness Following Glucose Uptake and Exercise with Baseline Vitamin D Levels in Inactive Men and Women

vitamin D deficiency is associated with many cardiovascular disorders. Arterial stiffness responses also depend on nutritional and exercise. Therefore, the study aimed to investigate the relationship between arterial stiffness response after glucose uptake and exercise with baseline levels of vitamin D in inactive men and women.The present study was an analysis correlation study, and the subjects were 88 inactive men and women with an age range of 20 to 45 years. Vitamin D, body composition, and arterial stiffness, were measured. Subjects then ran for 30 minutes at 65% of maximum heart rate. Also, 75g of glucose was given to the subjects after 30 minutes of activity, 60 minutes after the of glucose consumption and arterial stiffness was measured. Data were analyzed using Pearson correlation test and analysis of variance with repeated measures at a significant level (P≤0.05).there was a negative and significant relationship between baseline levels of vitamin D and changes in CAVI in women (p=0.001 and r=-0.559) and in men a positive and significant relationship (p=0.005 and r=0.413).It seems that basal levels of vitamin D can be effective in the vascular response; due to little research, more research is need.
