Thanks for the query.
This could be an exercise-induced intolerance, causing asthma or difficult breathing. There will be tightness in the chest and back as well. However, the other causes like gastritis, COPD, angina, etc need to be ruled out. Avoid exercising until you see a doctor.
Kindly consult a physician for an examination and tests like ECG AND ECHO. Pulmonary function tests to rule out obstructive and other airway disease needs to be done.
Avoid oily and spicy food. Make sure you drink plenty of water daily.
Avoid stress, smoking and alcohol too.
Hope this helped.
