Introduction

Asthma is a predisposition to chronic inflammation of the lungs in which the airways (bronchi) are reversibly narrowed. Asthma affects 7% of the population of the United States, 6.5% of British people and a total of 300 million worldwide.[3] During asthma attacks (exacerbations of asthma), the smooth muscle cells in the bronchi constrict, the airways become inflamed and swollen, and breathing becomes difficult. This is often referred to as a tight chest and is a sign to immediately take medication. Exercise-induced asthma is a medical condition characterized by shortness of breath induced by sustained aerobic exercise. It shares many features with other types of asthma, and responds to some typical asthma medications, but does not appear to be caused by the same inflammatory reaction as the other types. you cough, wheeze or feel out of breath during or after exercise, it may be more than exertion causing your symptoms. You might have exercise-induced asthma. As with asthma triggered by other things, exercise-induced asthma symptoms occur when your airways tighten and produce extra mucus.

On many occasions, patients have asked me whether exercise will help prevent asthma. This issue is receiving more attention in light of the global increase in the prevalence and severity of asthma and the ongoing efforts to explain this phenomenon. Could a change in lifestyle somehow be responsible for this trend in asthma? Scientists who work in this area have pointed out several childhood developmental and lifestyle differences during the past 40 years. (Philip, 2007, 878)

Discussion

People with asthma have what is called a chronic continuing problem with their airways, which can become swollen, narrowed, and clogged with mucus. To make matters worse, common stuff, like pollen and cigarette smoke, can worsen breathing problems and cause flare-ups. Most people with asthma (up to 90%) have symptoms when they exercise. And some people have asthma symptoms only when they exercise. This is called exercise-induced asthma (EIA).

Creatine is an amino acid that is stored in the liver and muscles. It's an all-natural substance that helps in muscle contraction and helps maximize a person's workout (Klein). Ninety-five percent of the body's creatine is found in the skeletal muscles. The remaining 5% are scattered throughout the rest of the body (Sahelian). Creatine can be found in protein foods like milk, steak and fish (Klein). The amount of creatine in a high protein meal can be reached by purchasing the supplement over the ...
