TUESDAY, July 26, 2022 (HealthDay News) — Your fitness tracker, pedometer or smartwatch can motivate you to exercise more and lose weight, according to Australian researchers.
In a large review of research, investigators found that tracking your activity could spur you to walk up to 40 minutes more per day (about 1,800 more steps). And those extra steps could translate to losing more than two pounds in five months.
“In the mainstream media, there can be a lot of skepticism about wearable activity trackers, for example if they make a difference and if they even have negative impacts, like making people feel guilty,” the company said. lead researcher Carol Maher. She is Professor of Population and Digital Health at the University of South Australia, Adelaide.
“Our review found no evidence of negative impacts from wearable activity trackers,” Maher said.
Devices are big business: Between 2014 and 2020, the number of trackers sold worldwide increased by nearly 1,500%. In 2020 alone, nearly $3 billion was spent on these products.
In the new study, which Maher said was not paid for by any fitness equipment manufacturer, his team found that trackers had a significant effect on the amount of physical exercise, and a lesser fitness benefit. physique and weight loss.
“There were also clear patterns of change in other physiological outcomes, such as arterial pressure and cholesterol,” she said. “The size of the benefits was sufficient to conclude that they are clinically significant.”
To determine the value of fitness trackers, Maher’s team looked at nearly 400 published studies, which included about 164,000 people.
“Wearables are a convenient and inexpensive tool to boost your daily activity and achieve slight weight loss,” Maher said.
While the reported 2-pound weight loss may seem insignificant, she said it’s important to remember that these weren’t weight loss studies, but ones that focused on physical activity.
