Calcium intakes of adolescent female gymnasts and speed skaters: lack of association with dieting behavior.
Calcium intake and its association with dieting behavior were assessed in female adolescents competing in an aesthetic and a nonaesthetic sport (gymnastics and speed skating). Athletes were 25 skaters and 32 gymnasts competing at a provincial level or higher. Calcium intake was assessed by food frequency questionnaire; dieting behavior by the Eating Attitudes Test Dieting subscale; and body composition by skinfolds, height, and weight. Mean calcium intakes of both groups of athletes exceeded Canadian recommendations, and skaters' mean intakes exceeded U.S. recommendations; however, many individuals had low intakes. Gymnasts were leaner than skaters and had lower calcium intakes, but this difference was not associated with Dieting subscale scores, which were similar between sports and were not correlated with calcium intake. Athletes had higher mean calcium intakes than normally active adolescents studied (measured with a similar protocol) and had lower Dieting subscale scores. Thus, although calcium intakes of some athletes require attention, sport participation was associated with increased intakes. Also, for these athletes, dieting behavior did not directly interfere with calcium intake.
