Cigarette smoking is well correlated with lung diseases such as chronic obstructive pulmonary disease. It is common among men than women in India. In addition, sedentary lifestyle is associated with less efficient pulmonary function. Effectiveness of upper body resistance training (UBRT) in improving pulmonary function is unclear. Keeping all these factors in view, this study aims to examine the effect of UBRT on pulmonary function in male sedentary smokers.
This study recruited 36 sedentary male smokers, of which 30 were randomized into two groups after fulfilling eligibility criteria-an exercising experimental group (EG) (N=15) or non-exercising control group (CG) (N=15). The EG group were assigned to exercise for 4 weeks, 3 times weekly on non-consecutive days using UBRT program and breathing exercise. In the CG, only breathing exercise was given for 10 min. Both groups were equivalent in baseline characteristics.
The improvement in forced expiratory volume in one second (FEV(1)) and FEV(1)/forced vital capacity (FVC) values were seen significant in EG after 4 weeks of UBRT: from 3.62±0.56 to 3.96±0.51 (P=0.000) and 0.88±0.11 to 0.96±0.13 (P<0.001), respectively. But FVC did not show significant change in the EG (P=0.430). There were no significant changes in FEV(1), FVC, and FEV(1)/FVC values in CG after 4 weeks of intervention. On intergroup comparison, significant difference was found between CG and EG for FEV(1) and FEV(1)/FVC values.
Four weeks of UBRT program brought about significant changes in the pulmonary function in male sedentary smokers.
吸烟与慢性阻塞性肺疾病等肺部疾病密切相关。在印度，男性吸烟的情况比女性更为普遍。此外，久坐不动的生活方式与肺功能效率较低有关。上身抗阻训练（UBRT）对改善肺功能的有效性尚不清楚。考虑到所有这些因素，本研究旨在探讨UBRT对久坐不动的男性吸烟者肺功能的影响。
本研究招募了36名久坐不动的男性吸烟者，其中30人在满足入选标准后被随机分为两组——运动实验组（EG）（N = 15）和非运动对照组（CG）（N = 15）。EG组被安排进行为期4周的运动，每周3次，在非连续的日子里使用UBRT计划和呼吸练习。在CG组中，仅进行10分钟的呼吸练习。两组在基线特征方面相当。
经过4周的UBRT后，EG组的一秒用力呼气量（FEV(1)）和FEV(1)/用力肺活量（FVC）值有显著改善：分别从3.62±0.56提高到3.96±0.51（P = 0.000）和从0.88±0.11提高到0.96±0.13（P < 0.001）。但EG组的FVC没有显著变化（P = 0.430）。干预4周后，CG组的FEV(1)、FVC和FEV(1)/FVC值没有显著变化。在组间比较中，发现CG组和EG组在FEV(1)和FEV(1)/FVC值方面存在显著差异。
为期4周的UBRT计划使久坐不动的男性吸烟者的肺功能发生了显著变化。
