Exercise intervention may offer therapeutic effects in asthma

Researchers have found that moderate- and vigorous-intensity aerobic exercise training may be effective in patients with asthma, according to a study published in The Journal of Allergy and Clinical Immunology: In Practice.

The researchers randomly assigned 46 adult patients with asthma to three groups: those undergoing 45 minutes of moderate-intensity aerobic exercise training three times weekly, those undergoing 30 minutes of vigorous-intensity aerobic exercise training three time weekly or a control group. They then examined the patients’ asthma-related quality of life, asthma control, cardiorespiratory fitness, body composition and airway systemic inflammation prior to and following the exercise intervention.

Compared with controls, the patients in the moderate-intensity exercise group achieved statistically and clinically significant improvements in their asthma-related quality of life and asthma control, whereas the patients in the vigorous-intensity exercise group achieved statistically, but not clinically significant, improvements in the same measures. Both groups experienced reductions in their sputum macrophage and lymphocyte counts compared with the control group.

As a result of the findings, the researchers recommended that both moderate- and vigorous-intensity exercise interventions may be used to manage asthma in the adjuvant setting.
