While the potential triggering events for EIB are well recognized, the underlying pathogenesis is poorly understood. [4] It usually occurs after at least several minutes of vigorous, aerobic activity, which increases oxygen demand to the point where breathing through the nose (nasal breathing) must be supplemented by mouth breathing.
Through pursed-lip breathing, patients get better at pacing their breaths during exertion. Otherwise, the instinct is to inhale and hold the breath—for example, while climbing stairs.
Shortness of breath (SOB), known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct ...
Exercise-induced laryngeal obstruction (EILO) is a transient, reversible narrowing of the larynx that occurs during high intensity exercise. This acts to impair airflow and cause shortness of breath , stridor and often discomfort in the throat and upper chest.
Acute onset of breathing problems caused by fluid accumulation in lung extravascular spaces induced by immersion, usually in cold water, often with intense physical exertion. Symptoms reported developed during physical activity and usually include dyspnoea/shortness of breath and a cough, often haemoptysis, occasionally chest tightness, chest ...
Hypoventilation training is a physical training method in which periods of exercise with reduced breathing frequency are interspersed with periods with normal breathing.The hypoventilation technique consists of short breath holdings and can be performed in different types of exercise: running, cycling, swimming, rowing, skating, etc.
