Turns out, activity trackers discourage teenagers from exercise

LONDON: Wearable activity trackers such as FitBit could be doing more harm than good in encouraging young teenagers to exercise, a study suggests.

Over decades, physical activity interventions targeted at young people in schools have only produced modest effects, researchers said.
The study from Brunel University London and University of Birmingham in the UK on school pupils aged 13-14 showed that wearing a FitBit for eight weeks demotivated the teenagers from exercising rather than encouraging them to do more.

Surveys and focus groups conducted before and after the trial period concluded that the device (in this case, the FitBit Charge wristband and app) ultimately made participants feel less confident about their competence at exercising, less connected to their peers, and less like they had autonomy or choice over how to engage with physical activity.

The FitBit app is designed with features to encourage competition and interaction among peers, and while pupils reported that they set up competitions in their friendship groups, the end result did not always have positive implications.

The FitBit 'community' often helped encourage pupils to engage with discussions about physical activity and develop common understandings and behaviours, but the competitive element also led to peer-pressure to achieve goals.

In some cases, it induced a sense of guilt and other negative feelings of self, researchers said.

Competition was an external pressure to engage in physical activity rather than an internal motivator, and while the desire to get to the top of the leader-board encouraged some participants to be more active, most of the pupils did not report engaging in activity 'for fun' during the eight-week period.
