Comparison the Effect of Two Different Intensities of Acute Aerobic Exercise on Plasma Concentrations of Apelin, Blood Glucose and Insulin Resistance in Type 2 Diabetic Men

The aim of this study was to compare the effect of two different intensities of acute aerobic exercise on plasma Apelin concentration, blood glucose and insulin resistance in type 2 diabetic men. Twelve type 2 diabetic men were selected and assigned to perform acute aerobic exercise training (mean ±SD, n = 12 age, 52.6 ± 3.6 yrs; height, 171.3 ± 6.7 cm; weight, 87.6 ± 4.7 kg). Anthropometric measures and maximal oxygen uptake (vo2max) were measured using a modified Bruce test. Acute exercise training was performed in two sessions (two different intensities 50% and 80% vo2max). Before, immediately and 24 hours after each activity, blood samples to measure plasma Apelin level, insulin, glucose and HOMA-IR were collected. Following the end blood sampling, data analysis was performed with two-way ANOVA with repeated measures and P0.05). Also, finding showed no significant difference in blood glucose and insulin resistance index in intensity, time and the interaction between intensity and time. It seems that high intensity of acute aerobic exercise has significant effect on the plasma level of Apelin in type 2 diabetic men. Although no significant effect on glucose and insulin resistance was observed.
