| 中文摘要: |
| 定期评估身体成分的变化，对监控运动员的成长、提高训练效果、评估健康及营养状况等都至关重要。传统的2C模型常常因选择不恰当的参考模型，造成测量误差。双能X线骨密度仪（DEXA）作为评估2C模型的金标准，在准确测量骨密度的同时，提供了更多全身和局部的肌肉和脂肪信息。由于它测量重复性好、快速简便、辐射量极低，在运动医学的身体成分研究中得到越来越广泛应用，是值得推荐的先进工具。 |
| 英文摘要: |
| To evaluate the changes of body composition regularly plays an important role in monitoring the growth of athletes, improving the training results, assessing the conditions of health and nutrition. The traditional 2C model often results in measurement errors owing to its inappropriate selection of reference models. DXA, as the golden standard in assessing 2C model, may measure the bone density accurately and provide more information on systemic and partial muscles and fat. It has been more and more widely used in body composition study of sports medicine due to its good measurement repeatability, quickness, simplicity and low radiation. Therefore, it is an advanced instrument worth recommending. |
