Setting Goals Crucial to Benefit from Activity Monitors
Although activity monitors are great holiday gifts, the device alone will not make their recipients active or healthy. New research finds that the trackers can have a significant health impact but only when users establish clearly defined objectives.
“To make activity trackers effective, users need to set a specific goal and stick with it,” said the study’s corresponding author, Luke Burchill, M.D., Ph.D., an assistant professor of medicine (cardiovascular medicine) in the Oregon Health & Science University.
“When paired with activity goals — such as 7,000 to 10,000 steps a day or 150 minutes of moderate intensity activity each week — these trackers can be powerful tools for increasing physical activity.”
Researchers, however, found that when people used such monitors without a specific goal in mind, their physical activity declined and their heart health did not improve.
This lackluster performance was despite 57 percent of study subjects thinking their activity had actually increased.
The study appears in the British Journal of Sports Medicine.
To counteract this tendency, Burchill recommends meeting with a medical professional such as a primary care physician to establish goals for specific health needs.
The study followed more than 400 healthy adults who were mostly office workers over the course of six months, starting in the summer and ending in the winter. The study participants’ steps were tracked every minute with an activity monitor worn on their wrists.
Like most of today’s activity monitors, the device used in this study had a three-way accelerometer — which measures motion up and down, side to side, and front to back — and an optical sensor to count heartbeats.
In the study, Burchill and colleagues assessed a variety of indications to ascertain cardiac risk: body mass index, cholesterol, blood pressure, and HbA1C, the three-month average of blood sugar.
Participants displayed a decrease in mean steps per day over the course of the study. Their cardiac risk factors also remained largely unchanged.
There was an increase in systolic blood pressure, but earlier research has shown blood pressure can increase during the winter months.
