If you have moderate to severe asthma currently being treated with drugs alone, the new study you can provide additional relief. According to the study by researchers at the University of Sao Paulo Medical School in Brazil, regular aerobic exercise may be more effective in controlling the symptoms that a regimen of drugs alone.
The study led by Dr. Celso Carvalho, participants were randomly assigned to a three-month exercise on a treadmill. Participants showed improvements in two areas that make breathing difficult asthma: the sensitivity of the airways and inflammation of elevated patient. Improvements have been found even among patients whose symptoms were under control with medication.
The World Health Organization estimates that 235 million people worldwide suffer from asthma, a chronic incurable disease. Asthma patients experience sudden onset of shortness of breath and wheezing. As the attacks occur, the lining of the bronchial tubes swells. The airways narrow and flow of air into and out of the lungs is restricted.
The anti-inflammatory drugs are frequently prescribed. Taken daily, can reduce inflammation and mucus production in the airways, relieving the symptoms of patients. Other asthma patients use medications called bronchodilators. The form of long-acting bronchodilator provides symptom control in progress, and the short form of action helps stop sudden attacks. Both work by relaxing the muscle bands around the airways, control of the entry and exit of air in the lungs.
Carvalho and his team of researchers examined the impact of aerobic exercise in 43 patients with asthma. Participants ranged from 20 to 59 years. His symptoms had been well managed by drugs for at least one month, and all of them had been monitored by their physicians for a period of at least six months.
Patients who had cardiovascular, musculoskeletal, or other chronic lung conditions, former smokers and people who were already getting plenty of exercise were excluded from the study.
Whether or not they were assigned to the exercise group, each participant in the study attended yoga breathing classes twice a week for 12 weeks. The exercise group also walked on treadmills for 35 minutes twice a week. At the end of the study, it was found that the exercise group have decreased bronchial hyperresponsiveness and extreme sensitivity resulting in narrowed airways. In addition, participants showed lower proteins known as cytokines, which are associated with inflammation levels.
