Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog ran from 2006 to 2016 and was intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Effect of tai chi vs a brisk walk on heart rate variability

    A study reported during the American Academy of Family Physicians 2007 Annual Scientific Assembly concluded, “tai chi is comparable to but not quite as effective as a brisk walk for raising heart rate variability.”

    First, the details as reported on Medscape

    • 24 adults either walked on a treadmill or performed 6-posture tai chi for 20 minutes with 5 minutes of rest.
    • After a week, they changed to the other exercise.
    • Heart rate variability (beat-to-beat alterations in heart rate) was recorded during both exercises.

    And, the results.

    • Heart rate didn’t differ significantly between the groups

    The bottom line?
    After viewing the poster, Dr. Ellyn Stecker, a family medicine physician from South Bend, Indiana, concluded, “If you walk at 6 km an hour, which is a little less than 3 miles, you’ll get a similar heart rate and blood pressure change. So, for people who can’t walk because they have arthritis or whatever, they might be able to do [tai chi] and still achieve the same cardiovascular benefits.”

    If you’re interested, more information about heart rate variability is here.
