J Speech Lang Hear Res:年轻人和老年人声乐加载时呼吸和喉部变化

2017-09-03 AlexYang MedSci原创

最近,有研究人员进行了旨在调查年龄和声乐加载对会洗和喉部系统的影响。研究包括了14名年轻人(年龄中值为20岁)和13名老年人(年龄中值为75岁)健康个体,并进行了40分钟的声乐挑战,同时具有70dB的背景噪音。研究人员在挑战之前和之后对呼吸运动和喉部进行了测量。研究发现,在加载了挑战后,两个小组的参与者都报道了需要更大的交流努力,并且声压水平在老年人组中增加而在年轻人组中减少。另外,在加载后,年轻

最近,有研究人员进行了旨在调查年龄和声乐加载对会洗和喉部系统的影响。研究包括了14名年轻人(年龄中值为20岁)和13名老年人(年龄中值为75岁)健康个体,并进行了40分钟的声乐挑战,同时具有70dB的背景噪音。研究人员在挑战之前和之后对呼吸运动和喉部进行了测量。

研究发现,在加载了挑战后,两个小组的参与者都报道了需要更大的交流努力,并且声压水平在老年人组中增加而在年轻人组中减少。另外,在加载后,年轻人,而不是老年人,使用更低的起始肺体积和更高的终点肺体积。对数倒谱的峰值凸显在两个小组中随着加载都增加,但是该变化程度较小并且没有临床显著性。

最后,研究人员指出,尽管变化的模式在两个小组中不同,加载的消极影响在呼吸和喉部测量中均存在。这些数据增加了人们对加载挑战对呼吸运动和喉部生理变化影响的认识,并且也许反应出了阐释声带疲劳的一些生理机制。
