Effect of low- intensity continuous training on lung function and cardiorespiratory fitness in both cigarette and hookah smokers.
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 smokers.
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\ub12.21%, p < 0.01) and hookah smokers (HS)
(+1.3\ub11.7 %, 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

Lung function profiles and aerobic capacity of adult cigarette and hookah smokers after 12 weeks intermittent training
Introduction: Pulmonary function is compromised in most smokers. Yet it is unknown whether exercise training improves pulmonary function and aerobic capacity in cigarette and hookah smokers and whether these smokers respond in a similar way as do non-smokers. Aim: To evaluate the effects of an interval exercise training program on pulmonary function and aerobic capacity in cigarette and hookah smokers. Methods: Twelve cigarette smokers, 10 hookah smokers, and 11 non-smokers participated in our exercise program. All subjects performed 30 min of interval exercise (2 min of work followed by 1 min of rest) three times a week for 12 weeks at an intensity estimated at 70% of the subject's maximum aerobic capacity (VO2max). Pulmonary function was measured using spirometry, and maximum aerobic capacity was assessed by maximal exercise testing on a treadmill before the beginning and at the end of the exercise training program. Results: As expected, prior to the exercise intervention, the cigarette and hookah smokers had significantly lower pulmonary function than the non-smokers. The 12-week exercise training program did not significantly affect lung function as assessed by spirometry in the non-smoker group. However, it significantly increased both forced expiratory volume in 1 second and peak expiratory flow (PEF) in the cigarette smoker group, and PEF in the hookah smoker group. Our training program had its most notable impact on the cardiopulmonary system of smokers. In the non-smoker and cigarette smoker groups, the training program significantly improved VO2max (4.4 and 4.7%, respectively), v VO2max (6.7 and 5.6%, respectively), and the recovery index (7.9 and 10.5%, respectively). Conclusions: After 12 weeks of interval training program, the increase of VO2max and the decrease of recovery index and resting heart rate in the smoking subjects indicated better exercise tolerance. Although the intermittent training program altered pulmonary function only partially, both aerobic capacity and life quality were improved. Intermittent training should be advised in the clinical setting for subjects with adverse health behaviors
