CHICAGO (Apr 03, 2016) -

A competition that used technology to encourage and track physical activity was effective at helping participants lose weight and exercise more in both developed and developing countries, according to a study presented at the American College of Cardiology’s 65th Annual Scientific Session.

The researchers analyzed the records of more than 68,000 people in 64 countries who competed in small teams to increase their daily physical activity levels during a 100-day technology-based “virtual race.” They found that on average, participants increased their amount of walking by more than 3,500 steps per day, exercised nearly one additional day per week, lost just over 3 pounds and reduced their time spent sitting by about 45 minutes per day.

“Physical inactivity, sedentary lifestyles and obesity are massive global problems that affect high-, middle- and low-income countries,” said Anand Ganesan, MBBS, Ph.D., associate professor at Flinders University in Adelaide, Australia, and the study’s lead author. “We need tools to get people moving that are attractive to consumers, that are affordable and that work on a large scale. Our study suggests that by using technology in a clever way, perhaps we, as a community, can devise solutions to this problem.”

The research is based on participant data for a 100-day international event known as Stepathlon. During annual Stepathlon events, participants are organized into workplace-based teams of five, issued an inexpensive pedometer and encouraged to increase their daily step count through an interactive, multi-platform application that engages them with frequent emails, quizzes and social media communication. Each five-person team competes with other teams around the world in a virtual race that culminates with prizes awarded in various categories at the end of the 100-day period.

“The idea is to increase physical activity and wellness, but in a fun and social way that builds on teamwork and camaraderie,” Ganesan said. “Stepathlon combines a number of lessons that we know are important to helping people change their activity levels and lose weight—it uses the power of mobile technology to remind users of the need to move, it provides a social group that encourages moving, and it builds on the lessons we have learned about self-monitoring using pedometers.”

Using data from Stepathlons held in 2012, 2013 and 2014, the research team analyzed participants’ physical activity and weight before and after each 100-day Stepathlon event. The results revealed improvements in all four parameters measured—daily step count, number of days per week in which participants exercised, amount of weight lost and minutes per day spent sitting.

More than 90 percent of participants were from low- and middle-income countries, and the results were consistent across countries of all income levels. “To our knowledge, our study is the first to provide comparative data on the effectiveness of this kind of intervention in both the developed and developing world,” Ganesan said.

The results were also consistent in both men and women and were similar across all three years studied.

Stepathlon is run by a start-up company in Mumbai, India, that charges a fee for participation. Generally, its fees—$62.50 per participant or $312.50 per team of five—are paid by companies that invite their workers to enroll as part of a workplace wellness program.

Ganesan said a key goal for future research is to evaluate whether the improvements were sustained after the Stepathlon ended. One limitation of the study is that researchers relied on self-reports from participants regarding weight and other parameters, rather than objective measurements. However, the large number of people included in the study and the fact that similar benefits were seen across all three years studied offer reassurance that the findings are robust, Ganesan said.

Being physically active and maintaining a healthy weight are seen as important parts of a heart-healthy lifestyle. Obesity, physical inactivity and spending too much time sitting down have been associated with increased risk of cardiovascular disease, adverse cardiac events and death.  

Ganesan receives financial support from the National Health and Medical Research Council of Australia. The researchers have no financial relationship with the start-up company Stepathlon, which provided data on an unrestricted basis for the purpose of scientific research.

This study was simultaneously published online in the Journal of the American College of Cardiology at the time of presentation.

The ACC’s Annual Scientific Session, which in 2016 will be April 2-4 in Chicago, brings together cardiologists and cardiovascular specialists from around the world to share the newest discoveries in treatment and prevention. Follow @ACCMediaCenter and #ACC16 for the latest news from the meeting.

The American College of Cardiology is a 52,000-member medical society that is the professional home for the entire cardiovascular care team. The mission of the College is to transform cardiovascular care and to improve heart health. The ACC leads in the formation of health policy, standards and guidelines. The College operates national registries to measure and improve care, offers cardiovascular accreditation to hospitals and institutions, provides professional medical education, disseminates cardiovascular research and bestows credentials upon cardiovascular specialists who meet stringent qualifications.


Ganesan will be available to the media in a press conference on Sunday, April 3, 2016, at 9:30 a.m. CT/10:30 a.m. ET/2:30 p.m. UTC in Room N229.

Ganesan will present the study, “Reproducible Impact of a Global Mobile Health (mHealth) Mass-Participation Physical Activity Intervention on Step Count, Sitting Behavior and Weight: The Stepathlon Cardiovascular Health Study,” on Sunday, April 3, 2016, at 8 a.m. CT/9 a.m. ET/1 p.m. UTC in the Main Tent (North Hall B1).
