ABSTRACT
Introduction:
Physical exercise has been proposed as a non-pharmacological treatment of diabetes due to its hypoglycemic effect.
Objective:
To investigate the acute effect of exercise on blood glucose in diabetics who use insulin or oral antidiabetic agents.
Methods:
We have studied patients using oral hypoglycemic agents (G1, n=7), non-diabetics (G2, n=8, control group) and patients using insulin (G3, n=8) at the Diabetic Association of Bauru (ADB). Subjects were submitted to clinical and biochemical evaluation, blood pressure and anthropometric measu-rements and to a session of aerobic exercise (60% to 80% HRmax). Blood glucose was measured at eight times during the session (M1 to M8). We used descriptive statistical analysis (mean ± standard deviation), and nonparametric tests used were Kruskal Wallis and Friedman's.
Results:
Participants were 23 individuals aged 59.35 ± 14.59 years, 17 female and six male. The blood glucose levels of M2 to M8 have been compared to M1, with significant reductions in times 4, 5, 6, 7, 8 (p ≤ 0.05). In the initial analysis of G1 and G3 were obese and G2 overweight. In the analysis of the variation in blood glucose during the exercise, it was observed that G1 and G3 have differed at times 2, 3 and 5, G2 and G3 at all times (p <0.05). There was a significant reduction only in G2 (control group) at times 4, 5, 6 and 7 (p < 0.05).
Conclusion:
Exercise has hypoglycemic action, however, in individuals with altered carbohydrate meta-bolism (G1 and G3) glycemic reduction is not so evident.
