Recognized methods for treatment are behavioral intervention (physical activity and diet) and pharmacotherapy. Regular physical activity can cause normalization of glycemia without the use of medication and diet. Aim: The aim of paper is to present the influence of regular, moderate physical activity on the metabolism and carbohydrate parameters without a change in diet or pharmacotherapy in a prediabetic 53 year old man. Material and Methods: A 53 male patient exhibiting abnormal glucose values for 6 years. The patient had a sedentary lifestyle and refused pharmacotherapy and diet restriction of simple carbohydrates. OGTT tests showed. 2021 fasting glucose at 115mg/dL and after 2 hours 86mg/dL 2023 106 mg/dL 2025 107 mg/dL The patient began physical activity (5 times a week running for 30 minutes, 2 times per week playing badminton for 90 minutes, and an increase in spontaneous physical activity). After a year of increased physical activity OGTT tests were performed resulting in normal results. 2026 fasting glucose 94 mg/dL, glucose after 2 hours 115 mg/dL Accompanying the positive glucose results there was a reduction of body mass from 100 kg to 92 kg. Conclusion: In a patient leading a sedentary lifestyle, physically little active after 12 months of regular physical activity, mainly aerobic there occurred normalization of glycemia and reversal of prediabetes.
