Feasibility of an Online Exercise Community Among Individuals With Type 2 Diabetes

Research Progression Criteria obtained through self-reported data from weekly questionnaires organized into the following categories:

Participant recruitment Completion of intervention Adherence to online physical exercise Adherence to the group meeting Adherence to goal setting Difficulty in participating in the objectively measured physical activity Improvement of physical activity Adverse events

Evaluation of participant recruitment was made by calculating number of participants recruited within three months.

Evaluation of completion of the intervention was made by calculating the percentage of participants who provided baseline and postintervention data out of the total number of participants at baseline

Evaluation of adherence to online physical exercise, participants received weekly web-based questionnaires instantly after the online physical exercise to respond whether they attended the session.

Adherence to online physical exercise was calculated by counting the number of completed online meetings separately, divided by the eight planned sessions.

Evaluation of adherence to online group meetings, participants received weekly web-based questionnaires instantly after the online meeting to respond whether they attended the session.

Adherence to online meeting was calculated by counting the number of completed online meetings separately, divided by the eight planned sessions.

During the 8-week intervention, participants wrote down a weekly activity goal for the forthcoming week and if they completed the activity goal from the previous week.

Difficulty in participating in the objectively measured physical activity was evaluated with a questionnaire at postintervention regarding participants' satisfaction with applying and wearing the accelerometers during the intervention

Evaluation of improvement of habitual physical activity, all participants wore axivity (AX3) (Axivity, Newcastle, UK) accelerometers for seven consecutive days before, during and after the intervention. Accelerometer data was considered valid if the participant had minimum 22 hours wear time out of 24 possible. A measurement period was considered valid, if the participant had at least three valid weekdays and one valid weekend day. Any improvement in habitual physical activity (daily counts per minute) from baseline to postintervention was considered as an improvement

Evaluation of adverse events involved experienced severity of adverse events in the postintervention questionnaire according to the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE®).

Minor adverse events covered dizziness, acute and prolonged musculoskeletal pain, and minor falls. Serious adverse events covered life-threatening events, disability, permanent damage, or hospitalization

• Change in behavioral physical activity measured using a weekly questionnaire and compared at baseline and post-intervention
• Change in mental well-being measured using a weekly questionnaire and compared at baseline and post-intervention. Self-reported mental well-being were obtained with the World Health Organization( WHO)-5-Well-Being-Index Health-Related Quality of Life ( HRQoL). Questions were scored from 0 (none of the time) to 5 (all time).

According to the recommendations, the raw score is multiplied by 4 to obtain a percentage score ranging from 0-100. The score was interpreted as following: 2.1. A score <50 was categorized as low HRQoL and described as being at risk for developing stress and depression 2.2. A score ≥50 was categorized as moderate to high HRQoL
