It’s over for the quick vape before training: what it does to teenagers at equal effort has just been measured, and it has nothing to do with the lungs
A groundbreaking study from Manchester Metropolitan University has found that vaping reduces exercise capacity by roughly 15% in young adults, despite normal lung function. The culprit isn’t the airways—it’s the blood vessels, which become less responsive to delivering oxygen during physical exertion. Teenagers are particularly at risk, as their cardiovascular systems may be especially vulnerable to e-cigarette chemicals during these critical developmental years.
