Physical training in people with asthma improved cardiopulmonary fitness without harming lung-function
Because exercise can worsen symptoms, people with asthma have often been prevented from playing sports or attempting to keep fit. But physical training programmes have been designed that enable these people to improve physical fitness, muscle coordination and confidence.
Working on this Review, the authors drew together the results of 13 studies that involved 455 participants. While the studies varied in the features they were setting out to measure, the researchers concluded that exercise can increase the total amount of oxygen a person can take in by up to 20%. It can also increase the amount of air a person can transfer in and out of their lungs each minute by up to 6L/min. Improvements in fitness were seen by a 6.27 watt increase in work capacity and an average increase in maximum heart rate of more than 3 beats per minute. All these changes are clinically important and will improve patient well-being.
One note of caution: "It is imperative to give asthmatic subjects guidance on how to prevent or treat exercise-induced asthma before encouraging them to start training," says Ram.
