Postprandial glucose is regulated by skeletal muscle movement, and exercise is the cornerstone of T2D therapy as it improves glucose uptake and metabolism in skeletal muscles. The ability to perform functional exercises is determined through (6MWT). To investigate the effect of 6mwt on glucose levels in patients with type 2 diabetes as well as to compare their functional abilities with healthy controls. Using a purposive sampling strategy, this case-control study included 62 subjects: 31 with T2DM and 31 with healthy controls. All the participants were nonsmokers with no pulmonary problems that could have influenced the 6MWT.Age, sex, and BMI were matched to each T2DM and healthy controls. We assessed demographic, anthropometric, biochemical, and physical parameters. The 6MWT was used to assess functional exercise capacity. The maximum amount of oxygen consumed (VO2 max) was calculated. Cardiac parameters and random blood glucose (RBG) were measured pre and post the 6-MWT. Descriptive and inferential statistics were used to analyze the data. p was chosen as the Alpha level < 0.05. There was a decrease in glucose levels post-6MWT in the T2DM group, with a mean and stander deviation pre (260.6±103.9) and post 6MWT (214.3±92.6). Type 2 diabetes patients had a lower functional exercise capacity than healthy controls, with mean and standard deviations of 6MWD and estimated VO2 max of (445.678.7) and (10.91.3) for T2DM and (529.770.1) and (12.31.1) for healthy controls, respectively. Blood glucose control will be enhanced by health education on self-care management, particularly walking. In comparison to matched healthy controls, exercise capacity is reduced in T2DM patients.
