Furthermore, in sports like gymnastics, diving and figure skating, attainment of a desired physical aesthetic is still considered important (Douda et al. 2008). Adding to these performance issues are current societal trends that encourage the pursuit of leanness for both men and women (Tantleff-Dunn et al. 2011). Unfortunately, the expectation of leanness has become increasingly important in sports where an image of physical attractiveness is desired for promotion or advertising. Athletes, or the sport itself, frequently derive substantial financial rewards for delivering an image and wearing clothing that accentuates physique (Simmers et al. 2009).
