Hello! With the question "Running about 100m is tired, can't breathe, is it due to lack of oxygen?" Do you have a history of cardiovascular or respiratory disease and do you regularly exercise with a similar intensity? Otherwise, with the age of over 40, you should check your Cardiovascular and Respiratory health before intense physical activity.
Thank you for your question to Vinmec Health System. Best regards!
