The purpose of this study was to determine the effects of a 12-week walking exercise using a mobile device on cardiopulmonary function, metabolic risk factors, and self-efficacy in obese middle-aged women. For this study, 14 middle-aged subjects with obesity were included and performed walking exercise of 50%–60% maximum oxygen uptake in-tensity 3 times a week for 12 weeks. As a result, weight, % body fat, body mass index, and waist circumference significantly reduced. In ad-dition, systolic blood pressure, diastolic blood pressure, mean arterial pressure, and hemoglobin A1c significantly reduced, while high-density lipoprotein cholesterol and flexibility significantly increased. Further-more, exercise using a mobile device significantly increased self-effica-cy. In conclusion, walking exercise using a mobile device is a good method to constantly increase the exercise participation rate, as it im-proves metabolic risk factor and obesity index, and increases self-effi-cacy.
