Table 3 Implementation of the intervention components

At 4 week review appointment

Set up participants with a MWC account, configure initial activity goals on the MWK and demonstrate how to use the device and web platform.

Take the MWK home, sign into their MWC account on their home computer and connect their MWK to read data and charge it.

Over the study period (48 weeks)

Interact with participants to monitor and adjust their goals, send positive comments and set up group challenges through direct messaging via a linked website called Professional Cloud.

Use the device daily and connect the MWK to a computer at least twice per week to upload data to the MWC, receive feedback and charge the device.

Manually enter information about activity that the device does not readily measure, i.e. swimming, weight training, cycling.

At 8 months from start

Telephone participants to check on their progress with exercising and remind them of the study and encourage use of the MWK, MWC and associated features.

Participants with a MWK continue to use it daily.

At 12 months from start

Exercise professionals will have a consultation with all participants for usual NERS assessments and to collect the MWK.

Hand the MWK back to the exercise professional.
