ABSTRACT EFFECT OF INTERMITTENT BREAK WITH LIGHT EXERCISE DURING PROLONGED SITTING ON POSTPRANDIAL GLUCOSE Alfa Christina Maria NIM: 1041005 The prevalence of diabetes is increasing, one of the main causes is a chronic hyperglycemia which is a result of prolonged sitting or sedentary lifestyle. One of the efforts to keep blood glucose levels in the normal limits is by doing physical activity intermittently during prolonged sitting. One physical activity that can be used is an exercise. Exercise is beneficial to control blood glucose levels, prevent heart disease, lower the risk of type 2 diabetes, and hypertension control. This study aimed to investigate the effect of intermittent exercise to postprandial blood glucose levels. This experimental study involved 30 adult men and women as research subjects with average age (20.9 ± 1.8), BMI (Body Mass Index ) (21.2 ± 2.9), systolic blood pressure (115.0 ± 14.4), diastolic (80.8 ± 11.5), and heart rate (79.8 ± 12.9). Participants were divided into 2 groups: the treatment group (3 minutes exercises) performed after 27 minutes (each treatment is 30 minutes period that consist 3 minutes exercise + 27 minutes sitting) and the control group (30 minutes sitting) for a duration of 300 minutes. Profile changes in blood glucose levels recorded in all treatments and were taken in 0, 30, 60, 90, 120, 180, 240 ,and 300 minutes. Paired samples T-test was used to compare the significance of the average value of the treatment group and controls with p = 0.69. The hypothesis that stated there is no effect of sitting without pause prolonged intermittent exercise on postprandial blood glucose levels is accepted. Thus concluded that the 3-minute pause exercises performed during prolonged sitting did not affect changes in postprandial blood glucose levels.
