Nasal Dilators and Athletic PerformanceE

A study in the journal from the American College of Sports Medicine shows that the nasal bands worn by many athletes help them to breathe in more oxygen and exercise more intensely (1).

These results are just the opposite of two studies reported in the same journal five months ago (2). When you have a cold, push the end of your nose upward and backward and you will get more air. The extra space in your nose should be of little benefit to an athlete during all-out exercise. The two openings in your nose have less than one tenth the surface area of your throat, so you have to take in most of your air through your mouth when you exercise intensely. However, this study shows that the extra air you get through your nose is enough to get you more oxygen and help you to exercise intensely longer.
