Acute effect of resistance exercise on anaerobic threshold in type 2 diabetic individuals

Abstract

Introduction: Type 2 Diabetes Mellituscan promote changes in the cardiac autonomic nervous system, during exercise and even in the recovery period, and can alter the lactic metabolism of individuals with this pathology. One way to assess these changes is through blood lactate collection. Objective: to investigate the acute effect of resistance exercise on lactic metabolism in diabetic individuals. Methods: The sample consisted of 14 diabetic individuals and 10 apparently healthy individuals, of both sexes. The anaerobic threshold was determined during the knee extension exercise (Roman table) and two tests were applied: one with 10% below and the other with 10% above the LA, each lasting one minute, maintaining spontaneous breathing. and without apnea. Results: The results of our study showed that there were more significant changes in lactate measured by blood from 30% of 1RM for the CG as well as for the DM2 group, the latter with more expressive changes when also compared with the loads of 40 and 50% of 1RM. Conclusion: Diabetic individuals tend to suffer greater and lesser metabolic stress when compared to apparently healthy individuals.
