Asthma UK said three quarters of people with asthma say physical activity is a trigger for their condition
People affected by exercise-induced asthma have been encouraged not to give up on sport after asthma sufferer Bradley Wiggins became Britain's most decorated Olympian.
Charity Asthma UK said that people who have the respiratory condition would be inspired by the cyclist.
The 32-year-old raced to glory in the time-trial around Hampton Court, giving him a record seventh Olympic medal, one clear of rower Sir Steve Redgrave, who has six.
Neil Churchill, chief executive at Asthma UK, said: "It is an amazing achievement and we're delighted that people with asthma might be inspired to follow in his footsteps.
"We encourage everyone with asthma to exercise as much as they are able to whether that's reaching the top of the stairs, the top of the nearest hill or the top of a podium, as keeping fit is good for your lungs and can help control symptoms."
Wiggins is one of a number of Team GB members who suffer from asthma. Swimmer Rebecca Adlington and 25% of the athletics team suffer from the condition, according to the charity.
Asthma UK said three quarters of people with asthma say physical activity is a trigger for their condition.
But the majority of people with exercise-induced asthma can take part in any sport they choose with proper training and medicine, the charity said.
Exercise improves lung function and can help with the management of symptoms, a spokeswoman said.
Endurance sports are most likely to cause problems for people with exercise-induced asthma, including long-distance running, cross-country skiing and cycling. Symptoms include coughing, wheezing, chest-tightness and difficulty in breathing.
