NCT05792657

Brief Summary

The ambition of the ABEL feasibility study is to test new "green prescription" follow-up models that can get more women with obesity, regularly active, with improved health and physical fitness. The project will evaluate the effect on exercise behavior, total physical activity level and mental and physical health outcomes by four different follow-up models by an exercise professional: HIGH-dosage in-person exercise coaching (four session monthly), MEDIUM- dosage in-person exercise coaching (two sessions monthly) LOW-dosage in-person exercise coaching (one session monthly). The main aim of this study is to evaluate which of these follow-up models is most effective on improving women's exercise adherence, total physical activity level, physical fitness, and mental and physical health. This will be weighed against the cost of each of the follow-up models, in order to identify the best model from a socioeconomic cost-effectiveness perspective. Moreover, the study will identify potential barriers among patients, General Practitioners and exercise professionals that prevents optimal outcome from the current green prescription model.

Outcome Measures

Primary Outcomes (1)

  • Adherence (attendance) to prescribed exercise sessions

    Measures of adherence to exercise sessions will be collected through the ABEL-app (ABEL Technologies). Sessions performed with the exercise professional will be logged through the ABEL-app of the exercise professional, while sessions performed independently will be logged through the ABEL-app of the participant. Participants adherence will be measured by attendance (percentage of exercise sessions completed out of exercise sessions offered).

    Continuously during the intervention period of 20 weeks

Secondary Outcomes (23)

  • Fulfillment of physical activity recommendations

    At baseline and following the intervention period (20 weeks)

  • Exercise frequency

    At baseline and following the intervention (20 weeks).

  • Duration of exercise sessions

    At baseline and following the intervention period (20 weeks)

  • Mode of physical activity

    At baseline and following the intervention period (20 weeks)

  • Health-related quality of life

    At baseline and following the intervention period (20 weeks)

  • +18 more secondary outcomes

Study Arms (4)

HIGH dosage in-person exercise coaching

EXPERIMENTAL

One in-person exercise session with an exercise professional/weekly. A total of 20 hours of in-person coaching during the 20 weeks of intervention.

HIGH dosage in-person exercise coaching

MEDIUM dosage in-person exercise coaching

Low dosage (one hour every month) of in-person exercise coaching by an exercise professional

Masking Details
Each participant will be randomly assigned (1:1:1:1) to one intervention group, HIGH, MEDIUM, LOW or CONTROL following a simple computer-based randomization program. All participants included in the study will conduct the baseline assessments before the randomization procedure. The study design will not allow for further masking of study participants or the exercise professional (caregivers to the interventions). Those from the research group involved in inclusion of the participants or follow-up measurements will not have access to the group allocation list. Further, all measurements will be completed and plotted without the research group information of group allocation. The statistical analyses will be done in SPSS, following a predefined analysis plan and before unmasking the study arms.
