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.
To examine the effects of continuous training on lungs functional capability and cardiorespiratory fitness in smokers.
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.
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.
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.
吸烟者心肺功能和肺功能的下降更为明显。训练方法可以减轻那些无法或不愿戒烟的吸烟者吸烟带来的一些负面后果。
研究持续训练对吸烟者肺功能和心肺适能的影响。
将15名吸烟者、14名水烟吸食者和14名非吸烟者分配到低强度持续训练组（以最大摄氧量（O2max）的40%进行20 - 30分钟跑步）。分别使用肺活量计和跑步机最大运动试验来测定肺功能和心肺适能参数。
持续训练使所有参与者（包括吸烟者和非吸烟者）的一秒用力呼气量（FEV1）和用力肺活量50%时的呼气流量（FEF50%）均有所改善（p < 0.05）。相比之下，用力肺活量（FVC）仅在吸烟者（CS）（+1.7±2.21%，p < 0.01）和水烟吸食者（HS）（+1.3±1.7%，p < 0.05）中有显著改善。同样，两组吸烟者的心肺适能均有所提高，CS组舒张压（DBP）无显著变化，HS组最大摄氧量时的速度（vO2max）无显著变化。
低强度持续训练可改善吸烟者（包括吸卷烟者和吸水烟者）的心肺适能并减少肺功能下降。这似乎对高血压预防计划有益。对于那些无法或不愿戒烟的吸烟者的预防和治疗计划可能具有重要意义。
