In the age of Fitbits and other wearables, consumers interested in living a healthy lifestyle have been trained to strive for 10,000 steps per day. But experts say that goal is arbitrary and isn't backed by evidence, David Cox reports for The Guardian.
According to Cox, the 10,000 steps goal is the result of a "successful Japanese marketing campaign" launched in the mid-1960s by sports health company Yamasa Tokei Keiki for what is believed to be the first wearable step counter. The device's name, manpo-kei, translates to "10,000-step meter."
But that number was not grounded in science, according David Bassett, head of kinesiology, recreation, and sports studies at the University of Tennessee. "They just felt that was a number that was indicative of an active lifestyle," Bassett said.
A research team in Japan eventually explored the number and determined that, for the average Japanese resident—who they estimated took between 3,500 and 5,000 steps a day—increasing their daily step count to 10,000 was indeed associated with a reduced risk of coronary artery disease. Since then, several studies have been conducted that seemingly reinforce the 10,000 steps per day goal, which has now been adopted by the World Health Organization, the American Heart Foundation, and HHS.
But Catrine Tudor-Locke of the University of Massachusetts Amherst's center for personalized health monitoring said these studies' findings are flimsier than they appear. The studies generally compared the blood pressure and glucose levels of subjects who are doing 10,000 steps per day with subjects that are doing significantly less—such as 5,000 or 6,000 steps.
The result, Tudor-Locke explained is "the study might find that 10,000 helps you lose more weight than 5,000 and then the media see it and report: 'Yes, you should go with 10,000 steps,' but that could be because the study has only tested two numbers. It didn't test 8,000, for example, and it didn't test 12,000."
In fact, Cox reports scientists have yet to confirm an "upper ceiling" for the number of steps people should take to achieve long-term health benefits. Research is currently underway to test whether 15,000 or 18,000 steps are more beneficial than the traditional 10,000-step benchmark.
But some experts warn that such an audacious goal won't be achievable for everyone, such as those who are older or have a chronic illness. Further, according to Cox, a sudden significant increase in daily activity could have "adverse consequences" for some, while others might be "intimidat[ed]" by the amount of exercise and avoid increasing their physical activity all together.
This has prompted some researchers to ask, what is the lowest step goal that would still produce benefits?
Bassett said some research has shown 6,000 steps or more per day is "protective against cardiovascular disease." Other studies have sought to identify a step goal equivalent to the much-recommended benchmark of 30 minutes per day of moderate exercise, finding that 7,500 steps would be an appropriate aim.
Another underexplored question is the intensity at which daily steps should be taken. "More recently, scientists have started looking at cadence, which is the idea of step rate or frequency of stepping," Tudor-Locke said. "When intensity's better, your heart is pounding a little faster, more blood goes through your body, things are crossing the cell wall that need to; all these things are happening quicker."
Regardless, experts say that any amount of physical exercise is better than none.
"We know that sedentary lifestyles are bad, and ... can lead to weight gain, increase your risk of bone loss, muscle atrophy, becoming diabetic and this litany of issues," Tudor-Locke said. With that reality in mind, according to Tudor-Locke, the obsession with 10,000 steps could be counterproductive if it stands in the way of "get[ting] people off their couches" (Cox, The Guardian, 9/3).

While several aspects of wearable technology—like the myth of 10,000 steps—might be more marketing hype than carefully researched practice, that doesn't mean that providers should overlook the enormous potential of wearables.
According to a 2018 survey by Accenture, consumer use of wearables has more than tripled since 2014. And the number of companies offering wearable products has also shot up—increasing the data captured from simple metrics like steps, sleep and heart rate, to more complex measures like acceleration, altitude, glucose levels, respiration rate, temperature, and hydration.
So how can your organization benefit from the rise of wearables? Here are two initial ways:
“These patients want a provider who will track this data”
If your organization is interested in wearables, our research has found that there are three top questions you should consider first:

Wearable technology encompasses the range of devices used by consumers to track their health- and activity-related data. As the multiple functions of wearables on the market continue to expand, consumers are becoming more invested in the potential for these devices to improve their daily habits. Wearable technology can help to facilitate patient activation and improve clinical outcomes.
