title: The influence of regular physical activity on lung function in paraplegic people.
abstract: METHODS
  Cross-sectional study.
  
  
  OBJECTIVE
  The main goal of this study was to examine the influence of regular physical activity (PA) on lung volumes and flows.
  
  
  METHODS
  The study was conducted in the Vall d'Hebrón Hospital, Barcelona (Spain), and La Fe Hospital, Valencia (Spain).
  
  
  METHODS
  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.
  
  
  RESULTS
  AG had greater values than the NAG: FVC (P<0.01), FEV1(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 FEV1(r=0.39, P<0.01) were obtained. The relationship between being physically active and reaching the LLN was statistically significant for FEV1(χ2=6.184, P<0.05) but not for FVC (P>0.05).
  
  
  CONCLUSIONS
  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 FEV1.
