许多优秀的女运动员在从高中过渡到大学水平（高级）体育运动的同时努力保持成绩。本研究旨在探讨影响优秀女子田径运动员升入高级组后身体成分的因素。42名优秀女子田径运动员，在日本排名前100名，参加了这项研究。在2016年和2017年的季后赛期间进行了全身模式双能X射线吸收扫描。运动员的表现采用国际田径联合会评分系统进行评估。研究了成绩变化与身体成分变化之间的关系。运动成绩的变化与脂肪量（FM）和脂肪百分比（FM%）呈显著负相关。这见于全身和下肢，而非躯干和上肢。此外，有一个性能和百分比瘦体重（LM%）之间的变化呈正相关。然而，性能变化与LM和总质量之间没有相关性。优秀女子田径运动员转入高级组后，应降低FM和FM%，增加LM%，以保持或提高成绩。监测身体成分的变化比体重更重要。
Many elite female athletes struggle to maintain performance while transitioning from high school to university-level (senior) sports. This study explores factors of body composition that influenced performance in elite junior female track and field athletes transitioning to the senior division. Forty-two elite female track and field athletes, ranked among the top 100 in Japan, were enrolled in this study. Whole-body mode dual-energy X-ray absorptiometry scans were performed during the post-season of 2016 and 2017. Athletes’ performances were assessed using the International Association of Athletics Federation scoring system. Relationships between changes in performance and those in body composition were investigated. There were significant negative correlations between changes in performance and fat mass (FM), and percentage FM (FM%). This was seen in total body and lower extremities, and not in the trunk and upper extremities. In addition, there was a positive correlation between changes in performance and percentage lean mass (LM%). However, there were no correlations between changes in performance and LM and total mass. Elite female track and field athletes transitioning to senior division should decrease their FM and FM% and increase LM%, to sustain or improve performance. It is also more important to monitor changes in body composition than body mass.
