title: Relationship between Short-Form Health SF36 Questionnaire and oxygen uptake in healthy workers.
abstract: BACKGROUND
  Physical activity is associated with better health levels, and cardiopulmonary fitness is recognized as one of the best indicators of physical performance, which can be related with some items of quality of life (QoL). The aim of this study was to analyze the relationship between the QoL and cardiorespiratory fitness (VO2max) of healthy workers, measured with the Short-Form Health Survey SF36 and incremental cardiopulmonary Test.
  
  
  METHODS
  Sample was formed by 250 healthy workers (90 men, mean age 37.25 and 160 female, mean age 37.91).
  
  
  RESULTS
  Analyzing the results, VO2's Mean values were higher in men (39.00 mL/kg/min SD 7.56) than in women (29.70 mL/kg/min SD 5.73) with significant differences (P<0.01). We found differences in all dimensions of SF36 indicating that men had higher scores than women, but significant differences between both are present only in physical functioning (PF) (P<0.01). Correlating the values obtained in the domains of Questionnaire SF36 and the Vo2 Max, correlation was significant (positive) in PF (0.276), bodily pain (0.189), general health (0.155), vitality (0.241) and mental health (0.129). Results showed that better cardiorespiratory fitness is related to higher scores in SF36.
  
  
  CONCLUSIONS
  These findings suggest that if the values of oxygen uptake in healthy workers are higher, results in SF36 will be better. Therefore it can be assumed that having a good fitness means having a better QoL.
