There are not many studies about the effects of physical activity on pulmonary function in normal population. However, it seems that strengthening and persevering respiratory muscles is an effective technique for improving pulmonary function.
The purpose of this study was to evaluate and compare the effects of eight-week aerobic, resistance, and interval exercise routines on respiratory parameters in non-athlete women.
Thirty-six non-athlete women between 18-25 years old participated in this prospective quasi-experimental trial. The subjects were randomly divided into three groups (aerobic, resistance and interval exercise, 12 in each group). Each group exercised three times a week for a total of eight weeks (24 sessions in total). Pulmonary function tests (PFT), including tidal volume (VT), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), inspiratory capacity (IC), vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in the first seconds (FEV), the ratio of FEV/FVC, peak inspiratory flow (PIF), and forced expiratory flow (FEF 25-75%) were recorded before and after the implementation of the exercise program for all participants. Data were analyzed using paired t-test and one-way ANOVA.
The mean age of participants was 20.17 ± 2.13. The results of the paired T-test indicated that VC significantly increased in the group assigned to aerobic exercise (P = 0.028), while IC (P = 0.012) and PIF (P = 0.019) significantly increased in the group assigned to interval training.
Our results showed that interval and aerobic exercise routines could improve pulmonary functions and aerobic and interval training can be used to increase VC, IC, PIF, in non-athlete women.
关于体力活动对正常人群肺功能影响的研究并不多。然而，增强并坚持锻炼呼吸肌似乎是改善肺功能的有效方法。
本研究旨在评估和比较为期八周的有氧运动、抗阻运动和间歇运动对非运动员女性呼吸参数的影响。
36名年龄在18至25岁之间的非运动员女性参与了这项前瞻性准实验性试验。受试者被随机分为三组（有氧运动组、抗阻运动组和间歇运动组，每组12人）。每组每周锻炼三次，共八周（总计24次训练）。对所有参与者在实施锻炼计划前后进行肺功能测试（PFT），包括潮气量（VT）、吸气储备量（IRV）、呼气储备量（ERV）、吸气量（IC）、肺活量（VC）、用力肺活量（FVC）、第1秒用力呼气量（FEV）、FEV/FVC比值、最大吸气流量（PIF）和用力呼气流量（FEF 25-75%）。数据采用配对t检验和单因素方差分析进行分析。
参与者的平均年龄为20.17±2.13。配对t检验结果表明，有氧运动组的VC显著增加（P = 0.028），而间歇训练组的IC（P = 0.012）和PIF（P = 0.019）显著增加。
我们的结果表明，间歇运动和有氧运动可以改善肺功能，有氧运动和间歇训练可用于增加非运动员女性的VC、IC和PIF。
