Objectives: This study aims to determine the effect of progressive muscle relaxation training on blood sugar, choleterol and uric acid levels in the elderly in Medan Sunggal sub-district. Methods: This research study used an pre-experimental one group pretest-postest with examination of blood sugar, cholesterol and uric acid levels before and after progressive muscle relaxation exercises. Respondents in the study were 39 elderly in environment II and III of Medan Sunggal District. Blood sugar, cholesterol and uric acid levels were measured before the first session and after the progressive muscle relaxation training session ended three times a week for 4 weeks. The implementation of progressive muscle relaxation therapy using a tool or standard operating procedure (SOP) with an instrument for measuring cholesterol, blood sugar and uric acid is a detection tool for the nesco multicheck-1 brand. Data analysis in this study using SPSS 26. Results: These results were analyzed using the Wilcoxon test using SPSS 26. Data analysis found that the value of blood sugar levels of 1,000> 0.05 means that Ha is rejected, which means that there is no effect between blood sugar levels and progressive muscle relaxation exercises. Cholesterol value 0.157> 0.05 means that there is no effect of cholesterol levels with progressive muscle relaxation exercises. However, it is different from the value of uric acid levels of 0.046 <0.05, meaning that Ha is accepted where there is a significant effect between pre and post Arduino Uno-based progressive muscle relaxation exercises. Conclusion: Progressive muscle relaxation exercises only affect uric acid levels and have no effect on cholesterol and blood sugar levels in the elderly. The implication of this study is that it is used for the elderly who experience impaired physical activity, joint pain and increased uric acid. The results of this study are expected to be able to improve the quality of life of the elderly well. Keywords: Progressive Muscle Relaxation Exercises, The Elderly, Arduino Uno. © 2020 The Authors.
