Background: The decline in cardiorespiratory fitness and lung function was higher in smokers. Training method could
mitigate some of the negative consequences of smoking among smokers unable or unwilling to quit.
Objective: To examine the effects of continuous training on lungs functional capability and cardiorespiratory fitness in
Methods: Fifteen cigarette smokers, 14 hookah smokers, and 14 nonsmokers were assigned to low-intensity continuous
training (20-30 minutes of running at 40% of maximum oxygen uptake (O2max)). Lung function and cardiorespiratory fitness
parameters were determined using respectively spirometer and treadmill maximal exercise test.
Results: Continuous training improved forced expiratory volume in one second (FEV1) and forced expiratory flow at 50%
of FVC (FEF50 %) in all participants, smokers and nonsmokers (p < 0.05). In contrast, forced vital capacity (FVC) improvement
was significant only among cigarette smokers (CS) (+1.7±2.21%, p < 0.01) and hookah smokers (HS) (+1.3±1.7
%, p < 0.05). Likewise, an improvement in cardiorespiratory fitness in both smokers groups without significant changes in
diastolic blood pressure (DBP) for CS group and in velocity at maximum oxygen uptake (vO2max) for HS group.
Conclusion: The low-intensity continuous training improves cardiorespiratory fitness and reduces lung function decline
in both cigarette and hookah smokers. It seems to be beneficial in the prevention programs of hypertension. It could have
important implications in prevention and treatment programs in smokers unable or unwilling to quit.
