title: [Relationship between physical activity and hemodynamic parameters in adults].
abstract: OBJECTIVE
  To analyze the relationship between physical activity, as assessed by accelerometer, with central and peripheral augmentation index and carotid intima media thickness (IMT) in adults.
  
  
  METHODS
  This study analyzed 263 subjects who were included in the EVIDENT study. Physical activity was assessed during 7 days using the ActigraphGT3X accelerometer (counts/min). Carotid ultrasound was used to measure carotid IMT. The Sphygmo Cor System was used to measure central and peripheral augmentation index (CAIx and PAIx).
  
  
  RESULTS
  Mean age 55.85±12 years; 59.30% female; 26.7 body mass index and blood pressure 120/77mmHg. Mean physician activity counts/min was 244.37 and 2.63±10.26min/day of vigorous or very vigorous activity. Physical activity showed an inverse correlation with PAIx (r=-0.179; P<.01) and vigorous activity day time with IMT(r=-0.174; P<.01), CAIx (r=-0.217; P<.01) and PAIx (r=-0.324; P<.01). After adjusting for confounding factors in the multiple regression analysis, the inverse association of CAIx with counts/min and the time spent in vigorous/very vigorous activity was maintained.
  
  
  CONCLUSIONS
  The results suggest that both physical activity and time spent in vigorous or vigorous activity are associated with the central augmentation index in adults.
