My daughter after the fast running of 6 circles

Patient: My daughter after the fast running of 6 circles on the lesson of physical exercise had a cough. Already after 2 circles of fast running she had shortness of breath.Normally it doesn’t happen because at school they usually don’t run so fast and so long and they can stop when they want. If it happened only after huge amount of running should I make her run more often to get accustomed her body to more exercise or let her run and exercise as much or as small as she wants.
