The aim of the master's thesis was to design and test a tele-exercise program for patients with diabetes mellitus (DM) at home and determine whether online tools can be a useful aid in remote exercise implementation. The study involved 7 untrained volunteers with type 2 diabetes mellitus (T2DM), aged between 35 and 65 years, who do not use insulin for treatment. Prior to the study, all volunteers had a consultation with a diabetologist, underwent initial measurements for body composition assessment, provided blood samples for glycated hemoglobin (HbA1c) analysis, and completed the PROM and PREM questionnaires. The 12-week physical exercise program included strength training through the Google Meet online platform twice a week. The intervention observational study showed that tele-exercise had a positive impact on body composition, glycemic control, strength, and endurance in diabetic patients. The greatest progress was observed in the chair stand test, which improved on average by 19.8%, and the 2-minute step test, which improved on average by 23.2%. Although the average values of body mass index and glycated hemoglobin have also decreased on average, the differences were not statistically significant. Despite the small sample size, the changes demonstrated a positive trend. Our results were consistent with similar studies that also found improvements in muscle strength and endurance. Some volunteers also showed reductions in waist and hip circumference, as well as body weight, indicating positive changes in body composition. The study demonstrated that tele-exercise positively influenced the overall well-being of participants, particularly in terms of improved sleep quality, energy levels, and motivation for physical activity. In conclusion, regular physical exercise, including remote teleexercise through online tools, contributes to improving the quality of life of patients with T2DM and enhances functional aspects such as muscle strength and endurance.
