10,000 Steps vs. Moderate Intensity ExerciseOne group exercised for 39 minutes per day at moderate intensity - where they were breathing hard but still able to speak one or two full sentences at a time. The pedometer group was only coached to log 10,000 steps per day at no particular intensity. A control group did neither form of exercise. After 6 months, the moderate intensity group had improved their respiratory fitness by 10%, compared with 4% for the 10,000 steps group. They also saw a greater benefit in reducing systolic blood pressure.
Pedometer Walking is a Great StartResearcher Dr. Vicki Harber said, "Getting people to do more than they currently do is imperative. The 10,000 step program is an excellent starting point. The pedometer itself provides instant feedback, is motivating for many and shows accumulated steps very nicely. It is self-paced and is geared toward getting people who do virtually nothing to do something. 'Something' is definitely better than nothing. So - we encourage people to accumulate 10,000 steps over the day. This would include shuffling back and forth from your desk to the photo-copier or the coffee machine as well as a hurried sprint to catch the bus. All the steps count."
Don't Stop with 10,000 Steps - Pick Up the PaceDr Harber continues, "Once the daily step count is higher, then the addition of some briskness is recommended. There are a growing number of studies showing the benefits (oxygen consumption, body fat control, lipid/glucose metabolism) of including higher intensity activity.
"We're not suggesting people start with higher intensity activity, it must be introduced once the person is accustomed to activity. As well, we are not suggesting that all activity must be performed at a high intensity. Periodic bouts of moderate to higher intensity (ie bouts of activity where speaking may be limited to 1 or 2 sentences at a time OR perhaps limited conversation)," Dr. Harber said in an interview for About.com
Increasing Your IntensityDr Harber had these recommendations for those ready to increase their exercise intensity:
- Make some of the steps harder - walk up hills and stairs.
- Go faster - try to do the same steps in a shorter time.
Increase Intensity GraduallyIf you do not typically have any intensity, you should start with small changes. Allow a gradual introduction to this kind of activity so the muscles can adjust. "If one goes too hard (too intense) or too long, the entire activity routine may be dropped. Work with the idea of progressive overload to give those tissues (joints, muscles - feet and knees are often sore ifyou start walking up hills, for example) - a chance to adapt to the challenge," Dr. Harber said.
Dr. Harber gave this suggested regimen to build time:
- Start with 10 minute bouts and work your way up.
- Do 10 minutes once per day, then twice per day'
- Do 15 minutes once plus 10 another time, then maybe 10 plus 5 and so on until you get up to 30 minutes.
