The decrease of blood sugar level in prediabetes patients can be done in various methods, such as Aerobic Exercise and Resistance Exercise. This study aims to investigate the difference of the decrease blood sugar level through Aerobic Exercise and Resistance Exercise in prediabetes patients. Experimental with pre test and post test two group design is used in this study. It was conducted in Tonja sub-distict, North Denpasar in January until March 2020. The research sample is 24 people, where 21 is woman and 3 man which are randomly divided into 2 experimental groups. Experimental Group I was given Aerobic Exercise and experimental group II was given Resistance Exercise. Glucometer is used as a measurement tool in this study. Based on the result of paired t-test, there is a decrease in blood sugar level in Experimental Group I, which the average before intervention is 146,58±21,33mg/dL into 126,42±21,03mg/dL after intervention and obtained p=0,001(<0,05). In Experimental Group II, the blood sugar level is decreased, where the average before intervention is 142,33±16,71mg/dL and after intervention is 121,83±20,83mg/dL and p=0,001(<0,05). There is no significant difference in the decrease of blood sugar level between two groups with p=0,948(>0,05). The conclusion is both Aerobic Exercise and Resistance Exercise have a good effect in decreasing blood sugar level. Keywords: Aerobic Exercise; Resistance Exercise; Prediabetic; Blood Sugar INTRODUCTION Trend and pattern or lifestyle always change with the times. Nowadays, the fact is many people have applied unheathly lifestyle, such as tend to have a sedentary lifestyle, unhealthy eating pattern, smoking habits, alcohol and drug consumption which increased degenerative disease (a disease caused by the decrease function of organ) which is life threatening. The effect of that is there has been a transition of Non-Communicable Disease and it is increasing along with some risk factors, such as increased blood pressure, blood sugar, body mass index (obesity), unhealthy eating pattern, lack of physical activity, smoking and alcohol. The excess amount of fat in an obese person causes insulin resistance. This conditions is happened due to the decrease function of insulin hormone to reduce blood glucose level. Normally, blood glucose is stored in muscle, liver or fat cells as energy resources. However, because of insulin resistance, glucose cannot enter to the cells so that blood glucose level tends to increase but has not caused clinical diabetes which is known as prediabetes. This sitation will eventually cause exhaustion in pancreas and unable to issue insulin as needed. It causes exceed and uncontrolled production of glucose in the liver, so glucose level in blood is increased and if it is left unchecked will lead to complications, such as type 2 DM (Diabetes Mellitus) 1 . Prediabetic is a condition where blood sugar level of a person is above normal but has not categorized yet into the criteria of Diabetes Melitus (DM) 2 . Blood sugar level is the amount of glucose in a blood although it is always changing. There are efforts to control blood glucose levels, such as by interventing pharmacotherapy and/or lifestyle mofication with diet, exercise or both 3 . The change of lifestyle, including exercise, can significantly delay or prevent type 2 DM (Diabetes Mellitus), lose weight, improve insulin sensitivity and improve the uptake of blood glucose in skeletal muscles through glucose transporter 4 (GLUT 4) 4 .
