Use Of Auditory Distraction To Alter Exertional Dyspnea In Young, Obese Females: A Case Study

Introduction: It is well understood that exercise is an important component in the prevention and treatment of obesity. Many obese adults are unable or unwilling to exercise due to dyspnea on exertion (DOE). Previous research has demonstrated that auditory distraction (AD) can reduce DOE in patients with respiratory disease. Exercise cardiorespiratory and perceptual responses with and without AD in obese females with DOE will be examined. Methods: The subject completed standardized tests of body composition, pulmonary function, and peak aerobic capacity during the initial visit. Intensities of breathlessness and unpleasantness of breathlessness were assessed during a 6 minute, 60 watts constant-load cycling test on two separate occasions. AD via headphones was presented during the exercise test on one of the two occasions. Negative affect dimensions were recorded after the exercise test using visual analog scales. Results: The subject exhibited normal pulmonary function and cardiovascular conditioning but reduced physical fitness. Ratings of perceived breathlessness, unpleasantness, and negative affect dimension scores were similar between the no auditory distraction (NAD) and AD trials. Conclusion: It appears from the current data that AD does not alter perceptual responses related to dyspnea in young, obese females. However, additional subjects are needed to complete the investigation.
