The purpose of this study was to gain further insight into the relationship between perceived energy expenditure (EE) for physical activity (PA) and age, gender, Body Mass Index (BMI), education, and leisure time PA (LTPA) levels. A 19-item interviewer administered questionnaire was completed by 798 individuals to assess accuracy of perception of EE (in calories) for various types of PA (sedentary, moderate and vigorous). Participants, age 21 to 64 years, were recruited from ten sites of the Department of Motor Vehicles in Miami, Florida. Only 30% were able to accurately assess EE for PA. Higher education and age were associated with greater accuracy. The range for estimated EE for PA was from 0-60,000 calories. These results are of interest as they suggest efforts should be made to educate the public regarding EE for PA in reference to energy balance and weight management.
