Catenacci, MD, a weight management physician and researcher at CU Anschutz Medical Campus.

Morning Exercise Lowers Blood Pressure






Wheeler’s group evaluated 67 sedentary participants with an average body mass index of 31.2 kg/m2and a mean age of 67.

Participants were assigned to each of the following in random order:

  • Exercise and breaks: sitting for 1 hour, moderate-intensity walking for 30 minutes, and then sitting interrupted every 30 minutes with 3 minutes of light-paced walking for 6.5 hours.
  • Uninterrupted sitting for 8 hours
  • Exercise and sitting: sitting for 1 hour, moderate walking for 30 minutes, and then uninterrupted sitting for 6.5 hours

The main limitation was lack of a group that only took breaks in sitting without more extensive exercise, Wheeler said.

“This was intentional, because we considered the evidence that an acute 30-minute bout of exercise impacts BP responses to be strong, and there are a number of studies that support the BP-lowering effect of active breaks compAdding a few minutes of walking throughout the day also helps, trial shows.
