Exercise-induced bronchoconstriction (EIB) is common in individuals with asthma, and may be observed even in the absence of a clinical diagnosis of asthma. Exercise-induced bronchoconstriction can be diagnosed via standardized exercise protocols, and anti-inflammatory therapy with inhaled corticosteroids (ICS) is often warranted. Exercise-related symptoms are commonly reported in primary care; ...

High altitude leads to an increase in sympathetic nervous system (SNS) activity and pulmonary arterial pressure (PAP). We assessed whether the SNS contributes to this increase in PAP. Sympathetic discharge to the pulmonary vasculature was assessed by measuring plasma norepinephrine concentrations in central venous blood entering the lung and systemic ...

In adult dogs following right pneumonectomy (PNX) and receiving all-trans-retinoic acid (RA) supplementation for 4 mo, we found modestly enhanced alveolar-capillary growth in the remaining lung without enhanced resting lung function (J Appl Physiol 96: 1080-1089 and 96: 1090-1096, 2004). Since alveolar remodeling progresses beyond this period and the lipid-soluble ...

It has been suggested that the potential for training to alter the physiological responses to exercise in children is related to a "maturational threshold". To address this, we investigated the interaction of swim-training status and maturity on cardiovascular and metabolic responses to lower and upper body exercise. Twenty-one prepubertal [Pre: ...

Performance in intense exercise events, such as Olympic rowing, swimming, kayak, track running and track cycling events, involves energy contribution from aerobic and anaerobic sources. As aerobic energy supply dominates the total energy requirements after ∼75s of near maximal effort, and has the greatest potential for improvement with training, the ...

Reasons for performing study: Frusemide (Fru) is widely prescribed for management of racehorses experiencing EIPH. The effect of Fru in the lung appears to be a reduction in transcapillary pressures and inhibition of the erythrocyte anion exchange, which may lead to attenuation of transpulmonary fluid fluxes during exercise. Hypothesis: Treatment ...
