This study explored links among body image, dieting behavior, and nutritional status among 40 nationally ranked junior figure skaters.
Questionnaires were provided to 40 junior skaters (range 12.9-22.9 years) during a skaters' camp. Food intakes were recorded over 4 consecutive days and blood samples were drawn. Nutritional status was assessed using food intake records and selected biomarker data.
Data suggested that these athletes dieted despite relative satisfaction with body image. Although biochemical measures of nutritional status were all within normal range, inadequate energy intakes and delayed menarche (in women) were widespread in this athlete sample.
Data dispute common theories of dieting being linked to dissatisfaction with body image. The article also cautions against overreliance on biochemical assessment as a marker of nutritional inadequacy.
本研究探讨了40名全国排名靠前的青少年花样滑冰运动员的身体形象、节食行为和营养状况之间的联系。
在一次滑冰训练营期间，向40名青少年滑冰运动员（年龄范围12.9 - 22.9岁）发放了问卷。连续4天记录食物摄入量，并采集血样。利用食物摄入记录和选定的生物标志物数据评估营养状况。
数据表明，尽管这些运动员对身体形象相对满意，但他们仍在节食。虽然营养状况的生化指标均在正常范围内，但在这个运动员样本中，能量摄入不足和月经初潮延迟（女性）的情况普遍存在。
数据对节食与对身体形象不满相关的常见理论提出了质疑。文章还告诫不要过度依赖生化评估作为营养不足的指标。
