I've been reading some papers on the effects of smoking on fitness and unsurprisingly, they all show how smokers tend to have lower VO2max and higher resting heart rates.
I was wondering if this means that smokers will also be less efficient at certain tasks compared to non-smokers.
If we were to take two identical people (same gender, BMI etc.), one a smoker and the other not, and made them walk a fixed distance on a treadmill at the same speed, would the smoker require more energy than the non-smoker?
If so, would this mean that if we measured their O2 consumption during the walk, the smoker would take up more O2 than the non-smoker?
The last part is what confuses me. A smoker shouldn't be able to take up as much O2 as a non-smoker (due to damaged lungs and CO competitively binding with hemoglobin), but if he is less efficient, he'll be taking up more O2 than the non-smoker.
I probably sound stupid and I'm sure I'm missing something very simple, but I need to know what it is.
