In brief: Sixteen professional ballet dancers from the Ohio Ballet in Akron were x-rayed, tested on a Cybex dynamometer, and tested for maximal aerobic power on a treadmill to determine musculoskeletal and cardiopulmonary capabilities. The x-rays indicated that the dancers had metatarsal abnormalities characteristic of such artists. The Cybex data were considered normal for the knee. The dancers had higher than normal cardiopulmonary capacity, although it was still in the range of nonendurance athletes.
对来自阿克伦市俄亥俄芭蕾舞团的16名职业芭蕾舞演员进行了X光检查、在赛百斯测力计上进行测试，并在跑步机上测试了最大有氧能力，以确定其肌肉骨骼和心肺功能。X光检查表明，这些舞者具有此类艺术家特有的跖骨异常。赛百斯测试的数据显示膝盖正常。这些舞者的心肺功能高于正常水平，尽管仍处于非耐力运动员的范围内。
