VAPERS are just as unfit as smokers, a study has found.
Both found it harder to breathe and became tired more quickly than non-smokers on an exercise bike, tests showed.
The findings add to concerns that the health implications of vaping are not yet fully understood.
In Manchester Metropolitan University’s study of people in their 20s, those who vaped produced a peak power output of 186 watts on an exercise bike and had an oxygen uptake of 2.71 litres a minute.
It was similar to tobacco smokers who generated 182 watts of energy and took in 2.6l litres of oxygen a minute.
But those who did not smoke or vape, hit 226 watts and three litres a minute.
Dr Azmy Faisal, who presented the data at the European Respiratory Society Congress, said: “The smokers and the vapers found it harder to breathe, their muscles became more fatigued and they were less fit.
Our research indicated vaping is no better than smoking.”
But statistician Prof Kevin McConway, who was not part of the study, said: “It is possible the results are caused by other lifestyle differences.”
VAPING has been touted as an effective tool to help people quit smoking.
Though vaping is substantially less harmful than smoking, the habit isn’t completely harmless and comes with its own set of risks.
The NHS only recommends it for adult smokers, to support quitting smoking.
GP and author Dr Philippa Kaye explained to The Sun that the differences between vaping and smoking – and whether one is better than the other – is “complicated”.
“In a nutshell, vaping is better than smoking, but breathing air is better than vaping at all.”
Vaping exposes users to far fewer toxins – and at lower levels – than smoking cigarettes.
Switching to vaping significantly reduces your exposure to toxins that can cause cancer, lung disease, and diseases of the heart and circulation like heart attack and stroke.
These diseases are not caused by nicotine, which is relatively harmless to health. But research has still linked vaping to a higher risk of failure and lung disease.
