Exercise interventions or engaging in regular physical activity is strongly associated with better measures of lung function, disease control, health status and use of health care services. According to a new review conducted by Leanne Tyson and team from the University of East Anglia in Norwich, England, interventions that promote physical activity could improve symptoms and quality of life for people with asthma. The review, published in the Journal of Health Psychology, examined 25 studies involving 1840 participants with varying degrees of asthma who in turn carried out physical activity interventions such as aerobics, strength or resistance training, yoga and walking, high-intensity interval training, indoor circuit training and aquatic training. The team said that 10 of the 25 studies showed significant improvements in relevant behavioural or health outcomes, as compared with people with asthma who engage in less physical activity and are more sedentary than people without asthma.
