Quizplus · Accepted Answer

Exercise-induced asthma is characterized by increased airway resistance, making it difficult for the individual to breathe normally during and after exercise. This is due to inflammation and constriction of the airways, which reduces the amount of air that can flow through them. Lowering atmospheric or intrapulmonary pressure, or inhibiting action potentials to the diaphragm, would not cause or alleviate these symptoms.
