Abstract
The pages of fitness, health, sport, and sport enthusiast (biking, running, bodybuilding, etc.) magazines are filled with advertisements for various nutritional supplements, all claiming to significantly improve the athletic performance of the supplement user. These advertisements often include dramatic “before and after” pictures showing greatly changed (improved) physiques that supposedly occurred as a result of taking the advertised supplement. The advertisements may also include pictures of individuals with impressively muscled physiques or pictures of famous athletes who claim to have achieved great results with the advertised supplement. However, “before and after” pictures are often altered. In some cases the pictures may even be taken on the same day and then altered on the computer (widening of the chest and shoulders, narrowing of the waist, airbrushing; Bell, 2008). In advertisements, muscular models might take the advertised supplement, but they also may ingest illegal steroids, use other products, and engage in other physique-altering activities (Bell, 2008). Furthermore, athletes providing testimonials for products are likely to be taking other nutritional supplements as well as participating in other performance-enhancing activities (physical training, getting proper rest) that may account more for performance outcomes than does taking the advertised supplement.
