They may be considered by many to be a fad, but new research by Irish scientists has found that smartphone fitness trackers do actually result in people taking more exercise.
The study, conducted by researchers at NUI Galway, saw 90 participants take part in an eight-week trial, in what’s thought to be the first ever randomised controlled research on the subject.
The volunteers were divided into two groups, with one group acting as a control and the other using an app.
The app featured a pedometer with live step count recording, which provided constant feedback to those involved.
The software also enabled the participants to set goals and receive visual rewards based on performance.
Both of the groups were given similar physical activity targets and information on the benefits of exercise.
The main difference, however, was the group using the app were taught how using the app could help them to achieve those aims.
At the end of the trial, the researchers found that those who used the smartphone pedometer had markedly increased physical activity over the period.
Compared to the control group, the app users had walked over 1000 steps more a day, equivalent to half a mile.
According to the scientists, the difference is clinically meaningful and over a prolonged period would increase physical fitness.
Some of those who used the smartphone app even saw decreases in their blood pressure and weight.
The researchers also found that the control group did increase their physical activity at the start, but this levelled off and returned to baseline rates by the end of the study period.
“There is real potential within healthcare to use these devices to explore, understand and positively change human behaviour”, said Dr Liam Glynn, senior lecturer in General Practice at NUI Galway.
“Our research has shown that significant improvements in physical activity rates can be achieved, which we know can lead to long term health benefits such as reduced risk of cardiovascular disease and diabetes.”
The study is published in the British Journal of General Practice.
