目的：住院医师培训的需求预计将导致身体状况的解除。这项研究确定了居住时间对身体健康的影响。方法：采用军队体能测试作为体能的标准化测量指标，对驻院期间体能变化进行前瞻性队列研究。从1999年7月到2002年6月，94名现役美国陆军医生在接受住院医师培训期间接受了跟踪调查。军队体能测试结果在整个住院期间进行的间歇测试结果与入学时的基线结果进行了比较。记录总分、2分钟内完成俯卧撑和仰卧起坐的次数、2英里跑时间和体重的变化。评估初始分数和最终分数之间的相关性。结果：所有测量的参数都恶化了，在体重(p<；0.01)、俯卧撑(p<；0.05)和2英里跑(p<；0.01)方面有统计学意义。在俯卧撑(p=0.004)、仰卧起坐(p=0.0003)和总分(p=0.0192)中，初始测试和后续测试之间存在显著的负相关。结论：住院医师培训期间体能下降。这种影响在医学教育开始时健康水平较高的居民中最为显著。有必要进一步研究，以评估平民居民中是否出现类似的下降。
Purpose: Demands of medical residency training would be expected to result in physical deconditioning. This study determined the effects of residency on physical fitness. Methods: A prospective cohort study of the change in physical conditioning during residency using the Army Physical Fitness Test as a standardized measure of fitness was conducted. Ninety-four active duty U.S. Army physicians were followed during their medical residency training from July 1999 to June 2002. Army Physical Fitness Test results from interval tests performed throughout residency were compared to baseline results at matriculation. Changes in total score, number of push-ups and sit-ups completed in 2 minutes, 2-mile run time, and weight were recorded. Correlations between initial and final scores were evaluated. Results: All measured parameters worsened with statistical significance noted in the weight (p < 0.01), push-ups (p < 0.05), and 2-mile run (p < 0.01). Statistically significant negative correlations between initial and subsequent tests were noted in push-ups (p = 0.004), sit-ups (p = 0.0003), and total score (p = 0.0192). Conclusions: Physical fitness declines during medical residency training. This effect is most notable in residents with higher levels of fitness at the start of medical education. Further studies are necessary to evaluate for a similar decline among civilian residents.
