Abstract:
Approximately 70-80% of all asthma sufferers develop acute airway obstruction with exercise, while at least 7% of children in the general population develop exercise-induced bronchoconstriction. The purpose of this study was: (i) to determine whether children in the Cape Peninsula who suffer from asthma and/or exercise-induced bronchoconstriction are as inactive and uninvolved in sport as asthmatic children in the USA; and (ii) whether this uninvolvement is a direct result of their susceptibility to exercise-induced bronchoconstriction. An in-depth study was done on the intensity, frequency and level of participation in sport by children with asthma and/or exercise-induced bronchoconstriction compared with a control group of healthy children without a history of asthma or exercise-induced bronchoconstriction. Children with asthma and/or exercise-induced bronchoconstriction generally maintained a similar level of sport participation as healthy children, and only children with serious asthma or exercise-induced bronchoconstriction experienced limitations with regard to physical activity. It was found that, in contrast to children in the USA, non-participation in sport could not be explained by asthma and/or exercise-induced bronchoconstriction.

Antiasthma Drugs: β2-Adrenoceptor Agonists
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce relaxation in these...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
