Dose considerations in the SO2-exposed exercising asthmatic.
In this study we have demonstrated that by combining data from several recent controlled human exposure studies it is possible systematically to relate increases in airways resistance to the rate of SO2 exposure (Dmin) in the exercising asthmatic. It was determined that the mode of SO2 exposure (oral vs. oronasal) greatly influences the degree of response in the asthmatic. Forced oral breathing...
متن کاملVoluntary decrease in breathing frequency in exercising asthmatic subjects.
Exercise rehabilitation programmes are increasingly recommended in young asthmatics, but it is unclear whether or not training should incorporate instructions on breathing pattern. In this study, we examined the effects of voluntarily decreasing breathing frequency on their ventilatory equivalents for oxygen and carbon dioxide (minute ventilation (V'E)/oxygen consumption (V'O2) and V'E/CO2 prod...
متن کاملEffects of inhaled salbutamol in exercising non-asthmatic athletes.
BACKGROUND Beta-2 agonists such as salbutamol are used, not only by asthmatic athletes to prevent exercise induced asthma, but also by non-asthmatic athletes as a potentially ergogenic agent. We have investigated whether inhaled salbutamol enhances endurance performance in non-asthmatic athletes. METHODS A prospective double blind, randomised, three way crossover design was used to study the ...
متن کاملAsthma in exercising children exposed to ozone: a cohort study.
BACKGROUND Little is known about the effect of exposure to air pollution during exercise or time spent outdoors on the development of asthma. We investigated the relation between newly-diagnosed asthma and team sports in a cohort of children exposed to different concentrations and mixtures of air pollutants. METHODS 3535 children with no history of asthma were recruited from schools in 12 com...
متن کاملNutrition and Supplementation Considerations to Limit Endotoxemia When Exercising in the Heat
Exercise-induced heat production is further elevated by exercise performed in hot conditions and this can subsequently impact inflammation, and gastrointestinal (GI) health. Implementing nutrition and supplementation strategies under these conditions may support the hyperthermic response, the systemic inflammatory response, GI permeability and integrity, and exercise performance. Therefore, the...
