Previous studies have failed to show consistent differences in pulmonary function between wind instrument musicians and normal controls. In this study, respiratory sensation was assessed in 13 professional wind instrument players and 13 age-matched controls. Psychophysical techniques were used to assess magnitude estimation and reproduction of lung volumes and inspiratory pressures. The exponent for volume magnitude estimation was not different in musicians and controls (1.17 +/- 0.11 vs. 1.16 +/- 0.11), but volume reproduction was more accurate in musicians. The mean exponent for pressure magnitude estimation was 1.34 +/- 0.14 and 1.06 +/- 0.09 (P = 0.057) in musicians and controls, respectively. There was no difference between groups for absolute or constant error for pressure reproduction. Professional wind instrument players appear to have some inherent or acquired differences in respiratory perception and ventilatory neuromuscular control compared with other normal subjects.
以往的研究未能显示管乐器演奏者与正常对照组在肺功能方面存在一致的差异。在本研究中，对13名专业管乐器演奏者和13名年龄匹配的对照组人员进行了呼吸感觉评估。采用心理物理学技术评估肺容积和吸气压力的大小估计及再现情况。音乐家和对照组在容积大小估计的指数上没有差异（分别为1.17±0.11和1.16±0.11），但音乐家在容积再现方面更准确。音乐家和对照组压力大小估计的平均指数分别为1.34±0.14和1.06±0.09（P = 0.057）。两组在压力再现的绝对误差或恒定误差方面没有差异。与其他正常受试者相比，专业管乐器演奏者在呼吸感知和通气神经肌肉控制方面似乎存在一些内在或后天获得的差异。
