Cross-sectional study.
The main goal of this study was to examine the influence of regular physical activity (PA) on lung volumes and flows.
The study was conducted in the Vall d'Hebrón Hospital, Barcelona (Spain), and La Fe Hospital, Valencia (Spain).
Spirometric tests were performed to 67 paraplegics, and differences were established between the active group (AG) (n=37) that performed >60 min per week of moderate-to-vigorous PA (MVPA) and 30 non-AG (NAG). Further, we established the relationship between the spirometric and PA variables and between being active and reaching the lower limit of normal (LLN) of the spirometric variables.
AG had greater values than the NAG: FVC (P<0.01), FEV (P<0.01) and PEF (P<0.01). Moderate correlations between the MVPA and FVC (r=0.41, P<0.01) and the MVPA and FEV (r=0.39, P<0.01) were obtained. The relationship between being physically active and reaching the LLN was statistically significant for FEV (χ=6.184, P<0.05) but not for FVC (P>0.05).
The performance of MVPA for a minimum of 60 min per week can have a beneficial effect, both on lung volumes and on expiratory flow, and led to an achievement of the LLN in FEV.
横断面研究。
本研究的主要目标是检验规律体育活动（PA）对肺容积和气流的影响。
研究在西班牙巴塞罗那的瓦尔德希伯伦医院以及西班牙巴伦西亚的拉斐医院进行。
对67名截瘫患者进行了肺活量测定测试，并在每周进行超过60分钟中等到剧烈强度体育活动（MVPA）的活跃组（AG）（n = 37）和30名非活跃组（NAG）之间确定差异。此外，我们确定了肺活量测定和PA变量之间以及活跃状态与达到肺活量测定变量正常下限（LLN）之间的关系。
AG组的数值高于NAG组：用力肺活量（FVC）（P < 0.01）、1秒用力呼气容积（FEV）（P < 0.01）和呼气峰值流速（PEF）（P < 0.01）。MVPA与FVC（r = 0.41，P < 0.01）以及MVPA与FEV（r = 0.39，P < 0.01）之间存在中度相关性。对于FEV，身体活跃与达到LLN之间的关系具有统计学意义（χ = 6.184，P < 0.05），但对于FVC则无统计学意义（P > 0.05）。
每周至少进行60分钟的MVPA对肺容积和呼气气流都可能产生有益影响，并能使FEV达到LLN。
