Asthma is a chronic respiratory disease that affects approximately 300 thousand people worldwide, 1 with numbers seemingly on the rise. The chronic disease is characterised by narrowing of airways from muscular contractions (bronchoconstriction mucus hypersecretion, episodic shortness of breath and chronic inflammation allergy of the bronchial membranes.
1, the chronic inflammation is associated with airway hyper-responsiveness (AHR) that causes recurrent wheezing, breathlessness, tightness of chest and coughing 2 particularly during the night, in the early morning or asthma during vigorous exercise. Causes of asthma are commonly termed atopic, meaning they stem from childhood or adolescence and can be traced back to particular triggers such as pollen, cold ambient temperatures or certain foods, or non-atopic, meaning they occur as a result of triggers that are not necessarily. 2, little research has been done into the possible pros or cons in exercising at altitude with asthma but potential insight may be drawn from existing literature on the concept.
Contents, exercise Induced Asthma edit, exercise induced asthma (EIA) is classified as the temporary constricting of the respiratory airways during or after bouts of intensive exercise, particularly those conducted outdoors where the air temperature and humidity can vary greatly, creating heightened stress on the respiratory.
3, research from recent Olympic Games has found that exercise induced asthma (EIA) amongst high end athletes is becoming more prevalent. 3, a recent study into elite sports and the rates of asthma found that 45 of road cyclists and mountain bikers displayed EIA (as did high quantities of swimmers and cold weather endurance athletes).
The common denominator between the statistics is that aerobic endurance exercises returns more asthmatic results.
This increased occurrence of EIA is leading to a heightened percentage of athletes using bronchial dilator medications, particularly in those endurance sports such as cycling (15.4 triathlon and swimming. 4, contemporary Asthma Treatment edit, the management of asthma today is constantly improving but frequently requires a tailored treatment plan consisting on various combinations of common treatments. It is has been found that women are more likely to suffer from asthma and encounter treatment difficulties as a result of their hormonal changes 5 and it for this reason that tailored treatment plans are commonly required.
The following are a list of common treatments 6 7 8, preventer Medictions (Corticosteroid inhalers for long term prevention). Relievers (Short acting beta-agonist inhalers for quick relief). Nebulisers (Vaporised liquid medication for inhalation).
The known benefits of aerobic exercise edit, there are known physiological and psychological benefits of aerobic exercise for asthmatic sufferers.
As asthma is consistently linked to abnormalities in temperature and humidity of respirated air, along with the sheer mechanical stress of a raised ventilation rate, 9 training at a wide variety of intensities has been shown to illicit various positive changes in physiology. The general concensise given by empirical literature on the topic have found the following: 10, improved peek expiratory flow (PEF improved forced expiatory volume in one second (FEV1).
Improved forced expiratory flow at 25-75 vital capacity (FEF25-75). Decreased airway inflammation, fewer symptomatic flair-ups, fewer emergency department visits.
