Objective:
To compare laryngoscopically observed changes in the larynx during exercise in persons with exercise-induced laryngomalacia (EIL) with changes in asymptomatic control subjects.
Study Design:
Clinical study using a standardized exercise protocol.
Methods:
Subjects exercised on an incremental ergometer: videotaped recordings of the larynx were obtained through the entire exercise; pulmonary function tests were completed before and/or immediately after the exercise.
Results:
Laryngeal lumen size decreases during exercise in subjects with EIL.
Conclusion:
Subjects with EIL had a significant decrease in laryngeal lumen size during exercise compared with asymptomatic control subjects.

Mechanism of Breathing II: Expiration
Expiration, or exhaling, is a complex physiological process that begins as the inspiratory muscles begin to relax. This relaxation triggers a series of events that epitomize the efficiency of the respiratory system.
Mechanism of Expiration:
Mechanism of Breathing III: The Accessory Muscles
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...

Respiratory Capacities
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.
The Functional Residual Capacity (FRC) represents the air in the...
Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
