[Q]: Question: Do athletes Condition Inspired Air More Effectively than Nonathletes during Hyperpnea?
Answer: This study shows no evidence of improved capacity to condition inspired air in endurance athletes, which could have suggested an increased bronchial blood flow or another adaptive mechanism. The absence of an adaptive mechanism could therefore contribute to airway damage observed in athletes in allowing colder but mainly dryer air to penetrate deeper in the lung.
[A]: no


[Q]: Question: Does greater body mass independently predict less radiographic progression on X-ray and MRI over 1-2 years?

[A]: yes
