Wearable Technology: are Physical activity and Fitness monitors useful ?

Once we come out of this COVID pandemic, everyone’s attention needs to be focused on the obesity pandemic.

During the COVID pandemic, lot of people started to focus on their physical fitness. People invested in Home Exercise equipment and in wearable technology such as Fitness monitors.

Even before this pandemic, lot of people have started using Fitness monitors.

Are they any good?

A recent study published in British Medical Journal (BMJ) looked the effectiveness of physical activity monitors.

The study authors looked at more than 120 trials involving more than 16 700 participants.

Most of studies they looked at were either European (31%) or North American (40%). Most of these studies included healthy participants (47%), although some included overweight participants (17%).

They found Fitness monitors are generally safe and help to increase physical activity.

Whether the Fitness monitors will help overweight people to lose weight permanently over long term needs further investigation.
