title: Acute effects of different aerobic exercise duration on pulse wave velocity in healthy young men.
abstract: BACKGROUND
  The purpose of present study was to determine the acute effects of different aerobic exercise duration on pulse wave velocity (PWV) in healthy young men.
  
  
  METHODS
  One week after measuring peak oxygen uptake to determine the duration of each exercise trial, 11 healthy males (age: 23.4±0.6 years, height: 172.5±2.3 cm, weight: 64.1±2.4 kg) cycled on an ergometer for 15 (15 min-EX), 30 (30 min-EX) and 45 minutes (45 min-EX) at 65% peak oxygen uptake in random order. After supine rest for at least 15 minutes, aortic (carotid-femoral) and leg (femoral-ankle) PWV were measured before and at 30, 60 and 90 minutes after each exercise trial.
  
  
  RESULTS
  Compared with before exercise trials, aortic PWV decreased at 30 minutes after 15, 30 and 45 min-EX (P<0.05, P<0.01 and P<0.05, respectively) and persisted for 60 minutes after 30 and 45 min-EX (P<0.05), leg PWV decreased at 30 minutes after 15, 30 and 45 min-EX (P<0.01) and persisted for 60 minutes after 30 and 45 min-EX (P<0.01, respectively).
  
  
  CONCLUSIONS
  These results suggest that PWV might be further decreased into recovery with prolonged exercise.
