The effect of exercise volume on lipoprotein metabolism in individuals with diabetes or pre-diabetes

Purpose: To determine the relationship between blood lipid and lipoprotein concentrations and the amount of exercise normally performed in individuals with diabetes or pre-diabetes. Method: Non-smoking adults who were diabetes or pre-diabetes and 45 to 85 years of age were participants. No attempt was made to alter the participants' medications during this investigation. Fasting blood samples and anthropometric measurements were collected, and were analyzed for blood lipid and lipoprotein-cholesterol concentrations. A Pearson Correlation was used to calculate the relationship between exercise volume and blood lipid and cholesterol concentrations. The exercise volume will be collected by a survey and the FitLinx system used by LEAD-UP. The criterion reference for statistical significance was set at P ≤ 0.05. Result: Thirty participants were included in the final analysis. Within these thirty participants, one was type 1 diabetes, 12 were type 2 diabetes and the rest of the participants were at borderline diabetes. TC concentrations was 188.4 ± 34.5 mg/dl, mean TG concentrations was 137.1 ± 48.6 mg/dl, mean LDL-C concentrations was 104 ± 33.3 mg/dl, and mean HDL-C concentrations was 56.9 ± 8.2 mg/dl. The average calorie expenditures from aerobic exercise were 251 ± 199 kcal/session. The frequency to perform resistance was 1.9 d/week and the frequency to perform aerobic exercise was 2.1 d/week. Conclusion: The results from present study indicated there was no significant relationship between exercise volume and the concentrations of TC, TG, LDL-C, and HDL-C. Therefore, exercise was not related to lipid profiles.
