Previous studies suggest that pulmonary function of singers and wind-instrument players may be better than normal control subjects due to breath-control training; however, prior studies were poorly controlled or limited in scope. In the present study, we compare 34 singers and 48 wind instrumentalists with a control group of 31 string or percussion instrumentalists using a pulmonary questionnaire, measurements of inspiratory and expiratory pressures, and spirometry. We found no significant difference between groups in maximum voluntary ventilation, forced expiratory volume in one second (FEV1), forced vital capacity (FVC), mean forced expiratory flow during the middle half of the FVC, the FEV1/FVC, peak expiratory pressure, or peak inspiratory pressure, independently or when corrected for age, sex, height, weight, years performing, smoking, presence or absence of cough, or sputum production. Smoking correlated negatively with measurements of pulmonary function in all groups. There was evidence of a heightened awareness of health among singers, who exercised more and smoked less than their colleagues. The differences in health habits may account in part for the myth of improved pulmonary volumes among singers.
先前的研究表明，由于呼吸控制训练，歌手和管乐器演奏者的肺功能可能优于正常对照组；然而，先前的研究控制不佳或范围有限。在本研究中，我们使用肺部问卷、吸气和呼气压力测量以及肺活量测定法，将34名歌手和48名管乐器演奏者与31名弦乐器或打击乐器演奏者组成的对照组进行比较。我们发现，在最大自主通气量、一秒用力呼气量（FEV1）、用力肺活量（FVC）、FVC中间一半时间的平均用力呼气流量、FEV1/FVC、呼气峰值压力或吸气峰值压力方面，各组之间没有显著差异，无论是单独比较还是在校正年龄、性别、身高、体重、表演年限、吸烟情况、是否咳嗽或咳痰后比较。吸烟与所有组的肺功能测量值呈负相关。有证据表明歌手对健康的意识增强，他们比同事锻炼更多且吸烟更少。健康习惯的差异可能部分解释了歌手肺容量改善的传言。
