title: Effect of acute moderate exercise on cognitive P300 in persons having sedentary lifestyles.
abstract: BACKGROUND
  There are conflicting reports regarding the effect of exercise on cognition. We therefore planned to assess the acute effect of moderate exercise on cognition, studied by event-related brain potential P300, in subjects having sedentary lifestyles.
  
  
  METHODS
  Sixty adults (40 males and 20 females) in the age-group of 18-30 years having sedentary lifestyles were included in the study. Baseline P300 was first measured and after that the subjects were divided into two equal age- and sex-matched groups. The test group was subjected to moderate exercise (that is, to achieve 60%-80% of maximum heart rate during exercise, where 100%=200-age) on a bicycle ergometer for 5 minutes, following which postexposure P300 was measured. In the control group P300 was re-recorded 15 minutes after baseline recording, without any intervening exercise.
  
  
  RESULTS
  The latency of P300 was found to be significantly reduced after acute moderate exercise in the test group.
  
  
  CONCLUSIONS
  It appears that acute moderate exercise improves the cognitive brain functions of adults with sedentary lifestyles.
