Definition of Pedometer

A pedometer is a small electronic device that you clip to the waist of your pants to track the number of steps you take. You can use it while walking or running for your exercise routine. When used properly, the pedometer can be a powerful tool that helps improve the consistency and effectiveness of your workouts.

How a Pedometer Works

When you first program your pedometer, you clip it to your waist halfway between your bellybutton and your side. Then program in the average stride length you want to record, be it a walking, jogging or sprinting stride. Inside the pedometer is a suspended lever that moves vertically when you raise your leg to step. Each time the lever raises the amount you programmed in, the pedometer records it as a single step and records the distance of that step.

Uses

The shortcoming of many physical activity programs is that a person does not regularly track his progress. Use your first week with the pedometer to establish a baseline for the number of steps you take per day. Once you know your average, you can gradually increase your daily steps and know exactly how much progress you are making.

Effectiveness

In 2007, a meta-research study conducted at Stanford University found that pedometer use increased a person's daily physical activity by just over 2,000 steps, or nearly one mile. More than 2,000 articles and 26 studies were reviewed to reach the conclusive results. Dena Bravata, the lead researcher for the study, also found that a person's body mass index decreased an average of .4 points when a pedometer was used to monitor daily workout activity.

Cost

Pedometers are a low-cost investment, considering their potential to motivate you for a healthier lifestyle. Generally, pedometers range in price between $10 and $35, as of 2011. Though they are inexpensive, it is recommended that you tie a piece of string to your pedometer as a safety catch because it is possible for them to unclip from your clothing while in use.
