GLYCEMIC RESPONSES AFTER ISOMETRIC EXERCISE WITH HANDGRIP IN ELDERLY WOMEN WITH TYPE 2 DIABETES MELLITUS: RANDOMIZED CLINICAL TRIAL

Abstract

Objective: To evaluate the effect of a single isometric exercise session with a handgrip on the glycemic responses of elderly women with type 2 diabetes mellitus (DM2). Methodology: This is a randomized clinical trial. The sample consisted of 14 elderly women with DM2, physically active, aged 66.29 ± 7.3 years. The participants were randomly divided into two groups, the control group (CG n = 7) and the intervention group (IG n = 7). With a handgrip dynamometer, the maximum voluntary contraction force (CVM) was measured in both hands. For the intensity of the experimental session, 50% of the CVM load found in the test was used. Capillary blood glucose was collected in the pre-times, immediately after (AI), 30, and 60 minutes after the intervention. Results: There was no statistical difference between interactions (group vs. time) and between groups. Only the IG showed a significant difference in relation to time (pre = 165.5 ± 39.4 mg / dL vs. AI = 139.2 ± 25.9 mg / dL; p = 0.026; pre = 165.5 ± 39.4 mg / dL vs. post 30 = 126.2 ± 17.1 mg / dL; p = 0.012; pre = 165.5 ± 39.4 mg / dL vs. post 60 = 120.8 ± 20.2 mg / dL; p = 0.009) when compared with the CG. Conclusion: Acute isometric exercise with a handgrip at 50% of CVM was able to promote a significant reduction in capillary glycemia levels in elderly women with DM2, exposed to the exercise protocol.
