<![CDATA[Diabetes mellitus (DM) in older adults is associated with impaired glucose regulation and reduced insulin sensitivity. Physical activity, including walking, is a non-pharmacological strategy that can increase skeletal-muscle glucose utilization. This study aimed to analyze the effectiveness of 30 minutes of walking on blood glucose levels among elderly patients with DM in Sedati Gede Village, Sidoarjo. A pre-experimental study using a randomized control group pretest-posttest design was conducted among 15 respondents selected through purposive sampling. Respondents were divided into five groups of three: a control group without a scheduled walking program and four intervention groups performing 30 minutes of walking for 3, 7, 10, or 14 days. Blood glucose levels were measured using a glucometer before and after the intervention. Paired Samples T-Test was used to assess pre-post changes within groups, while One-Way ANOVA was used to compare mean reductions among the five groups. The mean reductions were 10.33 mg/dL in the control group, 35.53 mg/dL in the 3-day group, 7.10 mg/dL in the 7-day group, 15.17 mg/dL in the 10-day group, and 14.07 mg/dL in the 14-day group. The One-Way ANOVA showed F = 0.408 with p = 0.799 (p > 0.05), indicating no statistically significant difference in reduction among the five groups. Nevertheless, all scheduled walking groups demonstrated clinically lower mean glucose levels after intervention, and the 14-day group showed the most consistent pattern of glycemic control. Regular walking may support glucose utilization through skeletal-muscle GLUT-4 activity. The absence of a significant between-group difference was likely related to the very small sample size and uncontrolled confounding factors.]]>
