Adherence
Smoking is associated with lower cardiorespiratory fitness and respiratory function, and smoking cessation is associated with better maintenance of these functions over time.
Quitting smoking improves cardiorespiratory fitness over time, even if you were a smoker previously. Never smoking is associated with the best maintenance of fitness.
GoodSupportsHIGH confidence
Smoking was related to lower cardiorespiratory fitness and respiratory function. ... After controlling for other variables, adults who never smoked had a greater mean change in MTT (1.50 minutes) than quitters (0.81 minute)... and persistent smokers (0.58 minute).
Why this rating
Large longitudinal cohort with controlled covariates.
