Time and time again, it has been documented that regular exercise has many health benefits including lowering risks associated with the comorbidities of obesity. With only 30% of Americans trying to lose weight meeting the National Institutes of Health exercise guidelines of 300 minutes/week, a study in the January/February 2010 issue of the Journal of Nutrition Education and Behavior explores the paradox that exists - an antidote for obesity and its comorbidities is exercise, but the majority of obese Americans do not exercise. Investigators explore and compare the barriers associated with regular exercise in health clubs between overweight and normal weight individuals.
Researchers at The George Washington University Medical Center examined overweight individuals' intent to exercise at health clubs by administering an online survey instrument based on Ajzen's Theory of Planned Behavior. This theory is based on (1) one's attitude toward the behavior in question, (2) the perceived social pressure (subjective norm) to perform the behavior, and (3) the ease or difficulty with which one can actually perform the behavior (perceived control). Of the 1,552 individuals surveyed, 989 were classified into the overweight category.
The researchers found overweight individuals believed exercise improved appearance and self image more than normal weight individuals. In addition, overweight individuals felt more embarrassed and intimidated about exercising, exercising around young people, exercising around fit people, and about health club salespeople than individuals of normal weight. Overweight and normal weight individuals felt the same about exercising with the opposite sex, complicated exercise equipment, exercise boredom, and intention to exercise. The study interestingly found that the demographics of older age and overweight Caucasians (versus overweight non-Caucasians) had more of an effect on exercise intent than did weight. Most notably, the heavier the subject's weight, the lower his or her perception of health. In other words, for the overweight, sedentary person, the negative emotions associated with health club exercise may be stronger in controlling regular exercise than the intellectual facts.
