The comparison of one session graded exercise test effect on fasting blood sugar in trained and untrained woman

Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 6, Issue 3

Abstract

Among the effects of various exercising methods, intensity and duration on blood glucose; aerobic exercise is considered as the main strategy to decrease blood glucose. Compared to long term aerobic exercise, one-session graded exercise test (Bruce treadmill test) program as an intense training takes lesser time and wider variety of patients can make use of it. The effects of exercise training on blood glucose may be important but have not been extensively studied in one session training. Therefore, the purpose of this study was to examine the acute effects of a one-session Graded Exercise Test (Bruce treadmill test) program as an intense training on Fasting Blood Sugar while considering the potentially confounding effects of sex, race, age, and BMI as well as changes in training status and physical fitness levels. Fifteen young (18–25 years) trained and fifteen young sedentary untrained controls women, matched for age and body mass index (BMI), were enrolled in the study. In order to evaluate halting levels of glucose, 5cc blood was drawn from anti-cubital vein in a sitting position after 12 hours of fasting in the beginning of the trial (pre-test) and at the end of the one-session graded exercise test (Bruce treadmill test) program (post-test). Concentrations of glucose were measured through GOD Photometric Method (using glucose kit made by Pars Azmoon Company-Iran with internal measurement degree of 1.28 and sensitivity of 5 mg/dl) respectively. A two-tailed independent samples t test was used for comparing of FBS means between the trained and untrained groups. The FBS means in pretest and posttest of each group compared with a two-tailed paired samples t test (p<0.05). Decrement of fasting blood sugar concentration in pretest and posttest of trained (p=0.002**) and untrained groups were significant (p=0.006**). The results of this study indicated that one-session graded exercise test (Bruce treadmill test) program were significantly decreased fasting blood glucose levels and corrected the pattern of diabetes in trained and untrained sedentary females. The results demonstrate an acute blood glucose reducing effect of one-session Graded Exercise Test (Bruce treadmill test) program as an intense training in trained and untrained women and of a magnitude similar to that obtained by others, even after one-session or a long period of exercise training.
